OHSW-Workshop in Garching (28.11.2015 & 29.11.2015)

[H. Nikolaus Schaller]

Hi,
we are still open for more presentations and participants for our yearly 
OpenPhoenux
workshop for the 7th time. Isn't 7 a lucky number (at least in some cultures)?

This event is a nice opportunity to meet old friends, present your latest ideas 
and projects
(if related to open hard and software), learn from others and also spend at 
least two
nice evenings in Garching / Munich. And participation is free (except travel 
expenses
and invested time).

Please refer to http://www.ohsw.org for details where location, times, how to 
register
etc. is described. You can also check what we have done in the past years to get
an impression what you can expect as speaker, workshop moderator or participant.

Awaiting to meet you in person,

your organizing team
(Nikolaus, Lukas, Christoph)

PS: please forward to mailing lists where you think interested persons are 
subscribed.

+++ last and final production batch GTA04A5 can be ordered now +++

[H. Nikolaus Schaller]

Hi,
waiting time is over. The GTA04 will be available again for a limited period!

We are happy to announce that we have organized everything to start preparation
of production next week (which means finally sourcing the remaining components, 
PCBs
and preparing everything else).

And, we have now been able to calculate a price that covers all cost (don't 
forget that
this project has no sponsor or investor who is willing to cover big losses).

For those who are already eagerly waiting, here is the link to the shop:



For all others here a full and lengthy description:

=== Products ===

GTA04A5:the new motherboards

GTA04A4:while preparing the GTA04A5 project we have found
a box with a handful fresh and unused GTA04A4 boards.
Most likely they were put aside for warranty handling 
and
then forgotten (because there weren't many warranty
cases). They are fully tested and working and 
immediately
available.

Letux 2804  we have collected a handful of used Neo Freerunner devices
where we can replace the motherboard and thanks to Ch. 
Pulster
we also got ~40 sets of plastic parts to build new 
Freerunner
cases. We also have enough spare displays so that we can
build "virtually new" devices from them.

Camera modules: unfortunately we have not found a supplier of a 100%
compatible module. We did get some samples of more or 
less
similar looking ones from China but none works.

=== Quantities ===

The quantities are really limited to 80-100 in total. The reason is that it
becomes almost impossible to source all components and for some of
them we can't get good replacements. Some others have been in stock
for a handful of years and may have weakened. The other important
limitation is availability of plastic cases or parts.

This means, we will produce ~100 GTA04A5 boards and expect to build
~40 Letux 2804 complete devices and provide ~40 more GTA04A5 boards
which you can install in your existing Neo Freerunner.

Yes, this will definitively be the last chance to get a GTA04. We will not
be able to build more units. Even if you offer to pay twice the price.

Well, if demand is high enough and someone finds a good strategy
how to compete with the cheap (but yery closed) ~79 € devices with
Android inside, we could develop a GTA05 :)

=== I did a preorder for a GTA04A5 a while ago ===

We have recorded it and updated your order for a GTA04A5 board

if your preorder was 100€ or more, i.e. counts as a reservation, we
have reserved a GTA04A5 for you (from the ~40). You will get a
personal "update" mail.

If you want to switch to a GTA04A4 or Letux 2804 please contact our
shop and we can change it.

Since the preorders/vouchers usually do not cover the final price of
a GTA04 or Letux 2804, there is an open balance which you can pay
by SEPA/IBAN bank transfer. Using Credit card is also possible but
needs a trick in our shop software so that you please contact us and
we will prepare a CC field for you.

=== Price ===

Oops, why is it so expensive.

Yes, that is the price we have from being in a niche and in need of something
very exceptional to play with.

But if you look at the original preorder page, we were even able to reduce
the price below estimates: http://shop.goldelico.com/wiki.php?page=GTA04A5

How does this magic work? The main reason is that we have some common
components and suppliers with the Pyra  and use
the same production company. They are better in reducing cost than the
company who did build the GTA04A3 and GTA04A4.

You might still doubt and think that we want to rip you off. Therefore I have
decided to publish a coarse calculation (always for 1 unit):

a) GTA04A5

 280€   Component cost
+63€Production cost
+52€HW Development&Project management
+50€Software maintenance funds (see below)
===
 445 €
+85 €   German sales tax (19%)
===
 529 €  price for GTA04A5

b) Letux 2804

 445 €  GTA04A5
+45 €   components for plastics case
+94 €   display, battery, box, assembly (time)
===
 584 €
+111 €  German sales tax (19%)
===
 695 €  price for Letux 2804

We are not getting rich. But we do something for open source and this community.

=== Software ===

First of all we already have a lot of software available:
* boot system
* kernel 3.7, kernel 3.12, ongoing kernel 4.3, 4.4-rc2 and later
* Debian Wheezy / Jessie images (X11 w/o or with LXDE, XFCE or whatever you 
apt-get install)
* Replicant for GTA04 with access to the F-Droid App-Store
* QtMoko (may not run 100% on GTA04A5 because it needs adjustments)
* whatever you like to install

But we know from experience that especially the

 The secondhand GTA04 I have now is pretty beat up and can't charge
 because the USB port is disconnected.  I've been using a spare
 GTA02 as a charger, but every time I switch out batteries the
 clock resets to 12/12/1999 16:00 and it's a pain to re-set it

 on the wiki about replacing the CMOS battery to solve this
 problem; has anyone here dealt with this same problem before and
 have recommendations?

The GTA04 already has a supercap in battery shape. They came to the market
in ~2011.

Since there is nothing to replace (a supercap rarely fails), it is most likely
a software issue that the charging current provided by the tpw65950 is not
enabled.

So which OS&kernel are you using? In most systems I know, the RTC
"resets" to 1st Jan 2000.

Should not be the case. You should move the USB+GPS socket as flat as
possible into or out from  the case. Then push out the case at the position
of the headset connector so that the latter snaps down a little in its hole.

This avoids breaking off connectors.

See also photos in chapter 4 (especially page 18) of the GTA04 system
manual:

That is fine and indeed sometimes needed if a socket was broken off.

 I disassembled a GTA02 enough to see the battery, but it didn't
 yield to gentle pressure trying to slide out of its bracket and I
 don't want to destroy things too badly in my attempt to fix them
 so I didn't push too hard.  Because of this, I don't even know the
 exact type of button cell to buy to replace it.  Any help would be
 appreciated.

The GTA04 original part is a PAS414HR-VG1.

BTW: it should also work in the GTA02 (which has a real 3.3V LiIon cell
in 414 package).

 
 Thanks,

BR and also good luck,

Welcome to the Tinkerphones community

[H. Nikolaus Schaller]

Hi,
after several years of running the OpenPhoenux community, we
thought that it is time to refresh it a little and replace the awkward
name "OpenPhoenux" (it was always difficult to spell and pronounce)
with something new, self-explaining, that your mom understands.

"OpenPhoneux" was originally coined in ca. 2009 as the name of an
initiative, when it became clear that the Openmoko company would stop
to develop a successor of the Openmoko Freerunner. It finally brought
the GTA04 device to life.

Back then, this was a motivating allusion to the situation of building
something new on the remains of Openmoko, but nowadays probably
only some core members of our community are able to understand
this background.

Therefore we discussed in a small circle what the core of Openmoko
and Openphoenux is.

It was easy to find what it is not:
* it is not a 100% fair phone (we don't have the resources to track
  components - it is enough challenge to have it working and being produced)
* it is not a 100% open phone (we have not found a feasible solution for
  WLAN and GPU)
* it is not a 100% secure phone (we can't do security audits of every
  component)
* it is not a cutting edge phone (we do not get the latest and greatest
  chips as mainstream manufacturers do)
* it is not a geeks (only) phone (we want everybody to be able to use
  it)

But then we found what the common denominator of all Openmoko
activities was and is:

It is a device that allows you to tinker with it, i.e. find out how it works,
to replace software and even hardware components for smaller or
bigger improvements and even repairs. It is designed in a way to enable
such changes instead of stopping you (e.g. by protected boot loaders,
undocumented code etc.).

All this is facilitated by being open (as far as NDAs and other limitations
allow) and using open source technology (e.g. GNU/Linux, Debian).

Here is a definition of what "tinkering" is [1]:

"tinker or tinker around to make small changes to something in order to 
improve or repair it"
"tinker with: He spends hours tinkering around with car engines."

So we are now happy to tell the world that we are members of
"the Tinkerphone community" :)

There is a new web domain representing this change:



I hope you will agree with us and stay here, contribute and share
your ideas and achievements. And invite new tinkerers to participate.

Happy tinkering,
Nikolaus

PS: it will need your help to update the documentation pages...

No, nothing. Just the the domain registration and minor changes to the mailing
list and home page.

So there is plenty of room for volunteers to make proposals and many topics for
our community to discuss.

I wonder where you want to get all the tiny glue components from...

E.g. toppoly display, pogo pins for speakers, speakers, vibramotor, battery 
connector, HF08 battery,
shields, just to name some. Many of them are EOL for years and almost 
impossible to locate even
through broker networks.

You may be able to find almost compatible replacements for *some* of them but 
then you have to
redesign everything and it is no longer a verbatim clone. BTW: it was already a 
problem when
designing the GTA04 years ago.

And: can you produce Neo Freerunner plastic cases?

Well, with necessary funding Goldelico would be mass producing a GTA17 this
year which would beat the latest iPhones and alike in quality, user-experience,
functionality and openness.

If we get enough funding, we can even get proper FCC/CE certification and
modify the standards so that a free&open modem can be certified. It is
all just a matter of getting a big enough budget...

Unfortunately, free&open is contradicting big-budget. Like Heisenberg's
uncertainty principle.

In that case, please convince him/her to spend money for more important
things. Like fighting diseases (incl. dictatorship and nationalism) and
rescuing endangered species (like homo sapiens).

Your wish is already fulfilled...

It is also (mirrored) on github:

https://github.com/goldelico/gta04-qtmoko

And the page http://git.goldelico.com/?p=gta04-qtmoko.git lists it in the "URL" 
section as

Hope this helps.

AFAIK git automatically adds a git: prefix if you say

Sorry, but no plans. We have no recent kernel or build system for it.

But you can still compile and modify it yourself based on the original

Linux gta04 4.1.0-rc4-gta04+ #1096 SMP Tue May 19 13:58:31 CEST 2015 armv7l GNU/Linux

[Dr. H. Nikolaus Schaller]

We are proud to have this kernel available for testing [1].

What is new:
* we have fixed a NULL pointer issue in the bq27x00 driver which was introduced 
by 4.1-rc1
* we are preparing for DT support of the camera module; the OMAP3 ISP (Image 
Signal Processor) should already be configured correctly
* everything else that is new with 4.1 and comes to us without big efforts

Some things we are still working on:
* get the GPS chip power managed on open(“/dev/ttyO1”). Technically it works 
since 2 years, but we need to find a solution that is accepted by upstream 
maintainers.
* some tweaks to the touch screen driver are needed to make it more general 
(and useable for Replicant)
* camera
* twl4030 battery driver (fallback for devices like L3704 where hdq is n/a)
* general power management
* sound (we still need to implement voice hardware routing, and headset 
detection)

Please give it a try (it also runs on BeagleBoard/XM, BeagleBone Black or 
PandaBoard ES).

As usual, collaboration is welcome and/or donations [2] to support this work.

I didn’t know about this event until some weeks ago - and I personally

Yes, that would have been a good occasion. But you can also send it to me
(any time you like) and I can return it next day (sometimes same day). It
needs around 10 minutes to repair if the person knows how to do it quickly
and reliable.

1st notice: Letux/GTA04 Kernel- and Userspace-Hacking weekend

[Dr . H . Nikolaus Schaller]

Hi all,
we (OpenPhoenux community Munich) are organizing a kernel- and user-space
hacking weekend to improve the Letux/GTA04 kernel and to make progress on
matching QtMoko with newer kernels and latest Debian.

This workshop is planned to have two groups:

a) Kernel - to work on the known (and new) issues [1], mainly power management,
but also others (e.g. Camera, Audio for GSM/FM/Bluetooth). The idea is to close
as many issues as possible.

b) QtMoko [2] - update the basis to Debian Jessie, make it compile,
add fixes so that we can use the latest kernels, make new packages.

The workshop location will be in Munich (Germany) area (details to be defined).
Date is also to be defined so that it fits for the participants, but the target 
is some
Saturday+Sunday in spring 2016.

We have a budget to support travel expenses.

Participation will be limited in the total number of people. I think a good 
group
size will be ca. 5 developers each. More is not productive and less is not 
enough
breadth of different experience.

If you think you can and want to participate and actively contribute, please 
apply
by a short mail to me, telling what you want to do and which expertise you have
and if you need support with travel expenses.

If you don't, but know somebody who could be interested and helpful, please
forward this e-mail.

Let's hope this helps to bring our community forward and fix some issues we
want to see solved for a long time.

BR and thanks,
Nikolaus

New 2.6.24.3 kernel and Debian Lenny for JZ4730 based MINIPCs

[Dr . H . Nikolaus Schaller]

Hi all,
as you may know we have worked a while on the JZ4730 based MINIPCs  
(available under different brands e.g. Letux 400) which are quite  
lightweight (ca. 670 g) and still low powered to make them a nice  
companion for the Freerunner with keyboard and larger display.

Now I think the kernel and rootfs efforts are ripe enough to be  
useable. We have recently fixed:

* missing touchpad button driver
* issue with RTC / i2c bus driver
* device did not power off after 'shutdown -h now'
* correct bootstrap of Debian Lenny base install (no X11 predefined  
but apt-get install is your friend...)

The kernel & rootfs can be installed on a two-partition SD Card and  
can (only) be booted from there (it is not yet ready for permanently  
flashing). More fixes will come to make it bullet proof and user  
friendly (e.g. LEDs should indicate caps/num lock etc.). Please also  
note that sound is not working correctly.

CDC Ethernet/USB connection of a Freerunner now also works out of the  
box following instructions at [1].

To keep things systematic there are two separate projects

a) Kernel

The Phoenux is coming: Openmoko Beagle

[Dr. H. Nikolaus Schaller]

Recently,
on 1st April,
we have made jokes about how the future might look for Openmoko devices.

The future begins now!

We can soon provide a printed circuit board ("Openmoko Beagle") that  
can carry a Freerunner display module (incl. touch screen) and is  
connected to a Beagleboard. It fits into a (slightly cut) Freerunner  
case (although you can do everything without destroying a Freerunner;  
only the buttons are a little more difficult to use).

Thus one can experience how a OMAP 3530 would feel inside a  
Freerunner. And with an external battery pack and a UMTS stick the  
whole thing is even mobile. See photos [1], [2]. A prototype had  
already been shown briefly during FOSDEM: [3] so you may think you  
have already seen this.

The U-Boot software is completed and even has a graphical menu: [4].  
Sources will become available together with the hardware.

For the Linux kernel, there is still some work to do. But it is  
essentially a BeagleBoard kernel plus Angstrom (or what ever you want  
to use). This means that experienced Freerunner users and developers  
can easily participate actively. And of course user-space software  
like SHR, QtMoko, Android, Debian, FSO, etc. can be ported...

With the new capabilities of the OMAP CPU (integrated vector-pipeline,  
3D graphics engine, separate DSP for audio / video processing) we can  
reach the power of a Pre Palm, HTC, N900 or iPhone.

Assuming that the community wants to aquire at least 50 units (please  
confirm!) and that the EUR does not crash, we think we can offer the
* empty PCB (with placement plan and shopping list) at around 49 EUR,
* a set of components (without display) for DIY soldering (but we  
don't recommend because of a few tiny SMDs and BGAs) also at 49 EUR.
* A populated board (without display) for ca. 99 EUR
* and ca. 169 EUR with a display module (if you do not want to  
disassemble your Freerunner).
Note: the OMAP3530 CPU is not on this board, so you must obtain a  
BeagleBoard separately.

So are you interested in giving your Freerunner an exciting new life  
[5]? Want to participate to really go in the direction of Free&Open- 
UMTS high-powered smartphones? This is not the end of development. It  
is a new beginning. Promised. Let's do it. Yes, we can. Etc.

We would appreciate your communicative, encouraging, financial and  
practical support and your questions.

There are approx. 3000 pages of documentation of every bit of the OMAP  
processor - except the 3d engine:

http://www.ti.com/litv/pdf/sprs507f

As far as I understand the situation, the kernel drivers are open  
source but the libraries are not. Details are described here:

http://elinux.org/BeagleBoard#Graphics_accelerator
http://code.google.com/p/beagleboard/wiki/HowtoUseSGXunderAngstrom

Without we still have graphics, framebuffer etc. to acces through X11  
and cairo. Just no 3D acceleration and OpenGL ES API. But the guys  
from OpenPandora are using it and show some 3D videos 
(http://www.youtube.com/watch?v=wnr4HCIoFlk 
). So it should be possible to get them for open source projects.

Openmoko Beagle Hybrid

[Dr. H. Nikolaus Schaller]

There is now a new Wiki page for the project:

http://wiki.openmoko.org/wiki/Openmoko_Beagle_Hybrid

I have received some questions why we did not put all this into a nice  
design. The main reason is that we can't redesign the Beagleboard (it  
has fixed dimensions) and we can't afford to build plastic injection  
moulds (if someone has an idea how to reduce cost this is very  
welcome). So the easiest solution was to combine what we have: a given  
Beagleboard and the Freerunner case.

Other questions were what one could do with this. Here some ideas (not  
assuming it is complete - you may have more and it is a platform for  
your creativity):

• experimenting with touchscreen and new user interfaces on Beagleboard
• learn how the OMAP3530 CPU works
• make it a truly open mobile application development platform by  
adding a battery pack and a UMTS usb stick
• investigate how an Openmoko with UMTS and OMAP3530 feels (not from  
haptics but screen operation and UMTS speed)
• porting SHR, QtMoko, Android, etc. to ARM-Cortex A8

And here some feature list:

• PCB that fits into Freerunner case (top cover and middle part after  
cutting a hole)
• works also without such a case (except speakers and earset)
• Toppoly LCM interface (same display as used in the Freerunner -  
otherwise it would not fit into the case)
• TSC2007 touch screen controller
• Microphone
• Earset and Speaker connector (for those sitting in the Freerunner  
case)
• 2 buttons (AUX and Power)
• 2 dual color LEDs (in the AUX and Power buttons)
• vibracall driver
• headset jack to connect microphone, earset and speaker

For the software, we have to rearrange the code on our server a little  
and then it will be made public.

Finally, here you can do preorders:

You are completely right in your expectation that we share. We would  
be happier if we could offer a motherboard replacement for the  
Freerunner. With OMAP and UMTS. But as Werner has already found out in  
the GTA02-core project this is still very far from becoming reality.  
The complexity is balancing circuit design with availability and cost  
of chips, and pcb layout with production processes.

Nevertheless, the great open source mobile phone software developed by  
this community (SHR, QtMoko, FSO etc.) needs to have modern open and  
documented hardware to keep pace with pretededly-open platforms like  
iPhone, WebOS, etc. Therefore, this Openmoko Beagle Hybrid board gives  
us a tool to develop mobile applications with state of the art  
performance (except form factor).

We, a small team of hardware developers, will continue to work on  
integrating everything better - but this is a long way to go. I am  
sure we will finally succeed because we have decided to do so, but I  
don't know when.

So it is better to have something suboptimal than nothing...

I don't know if there is enough room inside the case for a Gumstix.  
But generally, the Gumstix and Beagleboard are quite similar from  
circuitry. Maybe, the connectors (Video, USB-OTG, SD-Card, 2nd USB)  
are much different.

We didn't because we simply had more experience with the BeagleBoard  
and it costs less.

money) you need a volume of >200 units. If you make any small mistake,  
you have to repeat the process and cost will increase by factor 2...  
So it is not good for learning and protoyping.

The alternative would be 3D-Printing. There are now some quite good  
machines that can produce in ABS. Unfortunately these machines are  
rather expensive and operators want to have fast amortization. This  
raises cost of small quantities of cases like the freerunner well  
beyond 100 USD.

So our observation is that there is no method which allows to produce  
1-100 units for experimenting and testing - and still meets the  
expectations in quality and cost.

But we may have missed something. When I walked through the "Golden  
Mall" during CeBIT this year, I wondered how approx. 500 small asian  
booths could display approx. 50 different products each (headsets,  
mice, keyboards, batteries, plugs, covers, fake phones, real phones,  
etc...). Each one must have its own plastics. So I would estimate  
several million USD in moulds have been on display :)

A third alternative could be to experiment with Makerbot / Cupcake.  
Anyone tried to "print" a Freerunner case from the open 3D data?

Unfortunately the Beagle Board is too large. We have evaluated if wen

The general problem is making plastics. This is the most expensive  
investment if you want high quality (as used to from the Freerunner).  
But we will look into that and as soon as we have a solution...

Well ,we also reuse the earpiece and speaker.

Unfortunately no. The GPS system consists of ca. 50 components in  
addition to the pure chip. But you will see that the board has an area  
for a Wi2Wi GPS module (W2SG0004) with less external components - but  
we have not yet tested that. So it may be totally inoperable.

Re: Openmoko Beagle Hybrid

[Dr. H. Nikolaus Schaller]

The problem is not technology or DIY capabilities, but cost.

What we want to have is a nice case achievable for everybody, not only  
the enthusiast who wants to spend time and money for experimenting  
with DIY hardware or commercial FDM.

So the question is how much does a SW developer want to pay to get HW  
+ Case? Let's say 50 EUR per plastic case.

FDM is at least 200 EUR (that is what we got as a quotation from the  
rapid-prototyping shops for a simple part and not the whole case). Or  
700 EUR for a Cupcake. Or 5k for a protomold made thing. Or 10-20k EUR  
for a 3D printer. A full freerunner case consists of 6 plastic parts  
(incl. 2 buttons).

The other side is expectation of quality/robustness. I have been told  
by experts who own a RepRap/CupCake that the precision is not good  
enough to reproduce a Freerunner case (wall thickness 0.5mm).

Re: Openmoko Beagle Hybrid

Yes,
this all can be considered for a future version.

What we wanted to start with is something that just works, is easily  
available, can be used for experimenting and software development and  
is not too costly. A nice case, a new PCB for the OMAP processor or  
using the Gumstix makes things much more expensive.


@Yocto: what has to be considered is that the Gumstix does not fit  
into a Freerunner case (it is still too large/thick).


@ Martijn: the OMAP BGA poses high level requirements for a new PCB.  
So I would be surprised if one can really get such PCBs for 15 € @ 50  
units. But do you have more information? What have been your  
assumptions about # of layers, min. drill size, min. width etc.?

Hi,
First of all: nice project, could be a nice follow up for the  
freerunner.


I have been looking at the discussions a little bit. Main discussion  
is how to make a new casing that fits around the beagle board, how  
to produce and what it costs.
I haven't seen a discussion about redesign of the board, the design  
files (schematics in Orcad) are available, so you can downsize the  
connectors used and fit it in an existing casing. I have a price of  
a PCB (without parts) at low volumes (50 pieces) at less than €15.
Assembly of low quantitiy boards will be very expensive (make it  
double the components price), so a DIY project for assembly of the  
boards will make the PCB fit for a reasonable price.

Martijn


2010/5/11 Dr. H. Nikolaus Schaller 
There is now a new Wiki page for the project:

   http://wiki.openmoko.org/wiki/Openmoko_Beagle_Hybrid

I have received some questions why we did not put all this into a nice
design. The main reason is that we can't redesign the Beagleboard (it
has fixed dimensions) and we can't afford to build plastic injection
moulds (if someone has an idea how to reduce cost this is very
welcome). So the easiest solution was to combine what we have: a given
Beagleboard and the Freerunner case.

Other questions were what one could do with this. Here some ideas (not
assuming it is complete - you may have more and it is a platform for
your creativity):

   • experimenting with touchscreen and new user interfaces on  
Beagleboard

   • learn how the OMAP3530 CPU works
   • make it a truly open mobile application development  
platform by

adding a battery pack and a UMTS usb stick
   • investigate how an Openmoko with UMTS and OMAP3530 feels  
(not from

haptics but screen operation and UMTS speed)
   • porting SHR, QtMoko, Android, etc. to ARM-Cortex A8

And here some feature list:

   • PCB that fits into Freerunner case (top cover and middle  
part after

cutting a hole)
   • works also without such a case (except speakers and earset)
   • Toppoly LCM interface (same display as used in the  
Freerunner -

otherwise it would not fit into the case)
   • TSC2007 touch screen controller
   • Microphone
   • Earset and Speaker connector (for those sitting in the  
Freerunner

case)
   • 2 buttons (AUX and Power)
   • 2 dual color LEDs (in the AUX and Power buttons)
   • vibracall driver
   • headset jack to connect microphone, earset and speaker

For the software, we have to rearrange the code on our server a little
and then it will be made public.

Finally, here you can do preorders:

It is a probolem of the OM kernel that provides a random Mac address

Nikolaus,

I agree you should first play with something that is available.

The information I got is from eurocircuit.com,
The price is based on 4 layer 150 * 60 mm; just a wild guess of the  
size and layers based on standard technology, but giving an  
indication.
More about the possibilities can be read in http://www.eurocircuits.com/images/stories/ec09/ec-services-leaflet-uk-english-4-2010-v2.pdf 
. I did not check any guidelines and requirements, so hard to say  
what suits. If somebody could provide more detailed information or  
point in a direction, a more serious price could be obtained.


Ok, I see. They are a pooling supplier like others (pcb-pool,  
multipcb, etc.), but unfortunately such a project is well outside  
their offer.


Just to mention some more or less important differences (I have not  
looked into all of them):

* PCB thickness - 1.0 mm (or it will not fit into the Freerunner case)
* 8 layers needed (or we can't connect all the many pins of the OMAP  
BGA)
* stacked/filled Microvias (this is something like a minimum drill of  
0.1 mm)

* 0.1 mm wire width
* etching and stop mask printing precision good enough for <0.3 mm SMD  
pads (BGA pitch is 0.4 mm)


We have done some analyses and none of the online-pcb-shops can  
provide this. Therefore we asked several manufacturers by e-mail and  
most declined because they can't handle micro-vias. Some could do it  
but they said that our requirements drive PCBs cost up to factor 10. I  
don't know how the OpenPandora solved this (but they have produced  
4000 boards so the cost may come down through to large volume). And, I  
don't know how the BeagleBoard project solved this. But I have read  
somewhere that they have only 6 layers (not using all features of the  
OMAP) and 3000 units per batch. Maybe, someone has also sponsored the  
prototyping phase where you have to produce boards at 500 EUR each.  
And then you find one misplaced connection or component :(


For the Openmoko Beagle Hybrid we have just 2 layers (but no OMAP on  
board). So cost is much lower and comes into the range you have found.  
But we will add some margin to cover our development and prototyping  
cost.


So that is the status as of today. If we can find a design that has  
big enough demand, we can bring down cost of PCBs to be insignificant  
(but only if we don't change the PCB design every now and then).


This finally will lead to the question how many of us want to own such  
a new OMAP based motherboard for the Freerunner... But I think we are  
too early to really pose this question since for solid market  
research, one has to present at least a full concept (complete feature  
list and target price).

No, not at all. Both concepts are quite disjunct.

Our intention is to finally come up with a new OMAP based motherboard  
for a Freerunner and the OM Beagle Hybrid is a first prototype to  
support software and concept development by plugging together a  
BeagleBoard and an expansion board with a Freerunner LCD module [1]  
(plus some glue electronics).

The OpenPandora is a OMAP based gaming console with its own LCD. The  
OpenPandora is too big to fit into a Freerunner case. So connecting  
both doesn't make sense to me. Or did I misunderstand your idea?

iPhone 4G display for Openmoko?

[Dr. H. Nikolaus Schaller]

Hi all,
with the new iPhone it is for the first time better in display  
resolution (640x960 on 3''5 = 326 dpi) than the Freerunner (640x480 on  
2''8 = 283 dpi) with higher dots per inch.

Does anyone know where to get such a display? Who is making them?

Re: Openmoko Beagle Hybrid

[Dr. H. Nikolaus Schaller]

Hi all,
we were a little quiet the last days because we just had to wait to  
receive the final PCBs and some components and start testing the boards.

We are currently thinking about different offers:

1. PCB and very special components only (you can go shopping yourself).
2. PCB and complete component set (unsoldered)
3. PCB and components already soldered on a professional SMT line (we  
have one)
4. same as 3 including a Wi2Wi GPS receiver module (we are not sure if  
the internal Freerunner antenna module works, but an external antenna  
connected through the MMCX plug did work). This will increase the  
price of course.

But beware for variants 1&2: there are several 0402 components and one  
0.5mm pitch BGA (TSC2007) for which you need very special soldering  
eqipment.

Please let me know your preferences (either here or by private mail).

Best regards,
Nikolaus

If you are willing to pay, there are several thousands of SMT lines around the 
world to choose from. I think we could enter the same endless discussion as in 
software: what does "Free" mean? "Free beer" or "Free speech"?

> Any cost estimates for GTA02-core on that SMT line of yours ?

No idea. They need complete production documents to give a quotation.

If you have your own line, may I assume you would prefer option 1 or 2?

Hi Thomas,
our current plan is described here:

http://www.handheld-linux.com/wiki.php?page=Openmoko%20Beagle

but prices may change a little. Also depends on the outcome which variants you 
all prefer. And the number of units.

The status is that we have enough boards and are waiting to receive the 
stencils for "mass" production.

Anyway, can you please keep focus on the original question (everything else 
does not bring us forward):

Which option would you prefer?

1. PCB and very special components only (you can go shopping yourself).
2. PCB and complete component set (unsoldered)
3. PCB and components already soldered on a professional SMT line (we
can use one)
4. same as 3 including a Wi2Wi GPS receiver module

Yes, we also plan a variant with a LCD module which works without touching a 
Freerunner (you may use the Neo power supply).

The idea for a board with no LCM is that if you have a broken Freerunner 
collecting dust, you can give it a new life. And take the 
earpiece/speaker/vibracall that are mounted inside the plastics parts. But this 
is not reversible...

GPS is a functional option adding a GPS receiver module and a handful other 
components (RLC, ICs). So it is an independent option to choose from. This may 
add approx. 40 EUR.

So I should clarify the options:

1) bare PCB (and some key components only)
2) PCB and all components but nothing soldered
3) PCB with all components soldered
4) PCB with all components soldered and a fresh LCD module

5) PCB and all components (incl. GPS) but nothing soldered
6) PCB with all components (incl. GPS) soldered
7) PCB with all components (incl. GPS) soldered and a fresh LCD module

Since this are too many for us to handle, please let us know the variants you 
like. We will then decide which ones we will finally produce.

These are interesting chips.

To disclose a top secret: the OM Beagle Hybrid also has space for up to 1x 
ITG-3200, 2x LIS302, 1x HMC5843, 1x LSM303 (redundancy), and 1x BMP085, all 
connected to I2C2 of the BeagleBoard. In addition to the TSC2007 and a Wi2Wi 
GPS module. Let's cross fingers that at least some of them work :)

Christoph has already described one method that can be applied during 
prototyping.

For the Beagle Hybrid, we did go to our SMD company and they have equipment to 
solder that for single parts. I don't know exactly how they do it, but it could 
be something like this machine:

Ok,
I think this poll already made clear that most of you are interested in a 
completely assembled offer (for software development). And a fresh LCD module 
would help to save disassembling a Freerunner (unless you have a broken one 
that is being covered by dust).

So we drop the "kit" approach but keep the bare PCB just in case someone wants 
to have it.

The other question gives a strong preference for GPS.

We are still waiting to receive some components to verify that it (still) works 
on the new PCBs (this is in fact the second generation - the first one was done 
earlier this year). Nevertheless, you can already look into the data sheets of 
the W2SG004:

http://www.wi2wi.com/products/datasheets/W2SG0004_Datasheet_Rev1.81.pdf

And how to control the GPS receiver and antenna switch from user space:

http://projects.goldelico.com/p/gta04-kernel/page/Devices/

Comments and contributions to the project pages are welcome.

Hm. The Pandora connectors and the Beagle Board connectors are *very*

[ANN] AJZaurusUSB-0.6.0 (a better CDC Ethernet gadget USB driver for Mac OS X)

[Dr. H. Nikolaus Schaller]

Connecting a Freerunner to a Mac through USB is basically simple [1], but has 
its unique problems.

Major ones have been that the Freerunner is either not recognized by the Apple 
CDC Ethernet driver (depending on the versions). Or if it is recognized, but 
you have to configure a new interface after each reboot.

AJZaurus [2] as a GPL driver has been around since good old Zaurus times and 
does not show the "the everchanging Ethernet interface issue" (because it has 
special logic for presenting a Ethernet address towards the Mac OS X 
auto-configuration system).

But it also was a little flaky. The worst was that it could force the Mac into 
a Kernel Panic if the Mac went to sleep mode while the Freerunner was still 
connected. I put a lot of testing time into that issue but never found the 
reason. This week, I unexpectedly got a kernel panic which allowed me to track 
back the issue to its root cause and fix it.

Now, I am happy to release the new Version 0.6.0 [3] where this bug has been 
fixed. Please try it out and if encounter bugs and problems, please write to 
the Issues tracker.

Plans for Open Hard&Software Event in Germany

[Dr. H. Nikolaus Schaller]

There has begun an initiative on http://freeyourphone.de to activate and bring 
together (German speaking) people interested in different open and independent 
hard- and software projects in the form of a workshop/conference/meeting to 
exchange ideas, knowledge, projects and make friends. It will take place 
somewhere in Germany.

Topics we think of are (not an exhaustive list):

* Openmoko
* Arduino
* Nanonote
* OpenPandora
* Openmoko Navigation-Board
* BeagleBoard
* SHR
* QtMoko
* FSO

Although it may look centered around the Openmoko, it is not limited and other 
good projects and topics are very welcome.
To give a basis for planning, an online poll has been opened where you can 
place your ideas, wishes and proposals:

https://www.kwiksurveys.com/online-survey.php?surveyID=KLMDNG_d1f1fd00&UID=3164427512

Please forward to all your friends (and different projects) who may also be 
interested.

The organizer of the opinion poll has told that there are already 27 responses.

Since the poll will be closed tomorrow evening, please hurry up to state your 
preferences and wishes as described below.

Everyone from every country is welcome, but language will be German. Therefore 
I expect the location to be somewhere in Germany, but it may as well be 
Switzerland or Austria - depending on the outcome of the poll and organization 
hurdles.

Results are planned to be posted here, and further planning will be done 
through the Openmoko Wiki.

Re: can't flash kernel

[Dr. H. Nikolaus Schaller]

Do you use Ubunu Lucid 64 bit?
There has been a recent discussion on a German forum showing the same symptom 
[1].

The user has then tried to boot Ubuntu-koala-32bit from DVD, installed dfu-util 
and it did work fine.

I would suspect that dfu-util or libusb is broken on some 64 bit systems.

Well, for 1 position per second delays it may be neglectable, but you are right 
- having everything in one "middle-man" daemon (gpsd) appears to be the best 
architecture for me. So it hides the complexity from the user-applications, and 
should be easily expandable.

As far as I know, the kernel driver for the BMP085 barometric altimeter is 
already in some upstream kernel release candidate. So altitude information can 
be mixed between GPS and altimeter as well.

I would even suggest to use a Kalman-Bucy filter [1] for sensor integration so 
that it does not switch between two modes but does a soft transition. As far as 
I understand, a Kalman filter can also "learn" about (linear) errors, offsets 
and drift of sensors while multiple sensor data is available.

It is definitively possible to write such a Kalman filter for a smartphone 
since a student has recently been awarded [2] by VDE Germany (sort of a local 
IEEE) for such a project.

[ANN]: Openmoko Beagle Hybrid - News

[Dr . H . Nikolaus Schaller]

Hi all,
it is quite a while since our first announcement of the Openmoko Beagle Hybrid 
[1] and you may have wondered how the project is going. Since we have got a 
very positive feedback for our experiments and targets, we have tried to take 
seriously on all the feedback and worked on a new version (as far as it was 
possible in this phase). So let me report about news and progress:


1. The key software components (u-boot and kernel 2.6.29) are now available in 
a git repository [2] as well as binaries to be directly copied onto an SD card 
[3]

2. The binary downloads also includes an Debian Lenny rootfs demo image which 
is configured for our kernel and display/touch extensions. It opens LXDE and 
allows to run TangoGPS [4].

3. We have fixed a major hardware issue which had made the LCD flicker and 
behave strangely

4. Touch screen is working (but will need some more driver configuration).

5. We have joined forces with the Freerunner Navigation Board project 
(barometer, compass, gyroscope etc.) [7] and also have added such sensors to 
the schematics [10]. But since some the chips are very expensive, not all will 
be populated on the PCB.

7. And, a big majority did vote for inclusion of GPS. So we will add the Sirf 
III GPS receiver (W2SG0004) and the 3-Axis I2C gyroscope (ITG3200) although the 
board became a little more expensive than originally thought (129 EUR instead 
of 99 EUR).

8. We have received bare boards and components, have worked with a SMT assembly 
company, and now have nice boards which are ready to be ordered [5]. Since we 
need to test and pack them, we can ship in approx. 2 weeks.

9. Regarding the request of a nice plastics case, we got quite encouraging 
ideas and proposals. E.g. using RepRap/Makerbot/Cupcake like 3D printers [6]. 
But this needs much more study and a long learning phase. Since the Openmoko 
Beagle Hybrid is more a development tool rather than a product, we will see 
what we can achieve. If you have such a 3D printer, please try to "print" a 
Freerunner case and report results (e.g. precision, appearance, quality, speed)!

10. We also got some hints and offers for support to make high-density PCBs 
that are needed for the integration of a full OMAP system onto a motherboard 
replacement for the Freerunner. So we now think that finally, *we can do* a 
OMAP3530 upgrade for the Freerunner. But don't expect it soon. And it may not 
be cheap. This project will still take many small steps until we can announce 
something. One of the major hurdles we see is that we will have to pass CE, 
R&TTE certifications (since we have to add radio hardware). This is the 
ultimate challenge for a small team devoted to open hardware and software (even 
if backed by a company like Golden Delicious Computers). So we prefer to 
exercise for this "tournament" behind the curtain.

11. The best way to support our (current and future) projects is to buy the 
Beagle Hybrid [5]. And do experiments with it. Learn how to use and/or modify 
OMAP3530 software and give us feedback through a dedicated mailing list [8].

We would be very pleased if distributions like SHR, QtMoko, and others also 
start to support this hardware/kernel platform. It is not difficult since user 
space is quite compatible to the Freerunner and/or Beagle Board and Open 
Pandora. First experiments of just running the untarred Freerunner-rootfs of 
QtMoko were quite promising (we got touch calibration and were asked for 
choosing a user language before some component did segfault).


So, let me invite you to help to build a new future of Openmoko devices!

Nikolaus

Assume, you could get a motherboard upgrade board that fits into the Freerunner

Let me ask two questions to everybody:

* How much would you think you could afford to pay for such a board?

Yes, I remember this as well. And, there was also some recent initiative by 
'leviathan' to discuss with Samsung. But IMHO, even if they open the hw specs 
for one device, this will be one device. No promise for a future one. Some day 
they simply pull the plug for unknown reasons (like Sharp did with the Zaurus).

And, I never understood why we should assume, that a premier league player 
would ever care for a small community like ours. According to latest Gartner 
data Samsung sells 65 million phones per quarter. We have approx. 15k 
Freerunners over 3 years.

My conclusion is that a small company promises more long-term stability than a 
large one, even if development cost is high (it is lower than you all assume), 
and component cost are high in low quantities (that depends a little on 
choosing the right components).

I wasn't open enough, intentionally :) Yes, there is a serious possibility.

The Openmoko Beagle Hybrid Board is a first step for those who want to be early 
participants of this new era.

In addition, we (a small project team in Munich, Germany) have mostly finished 
our homework (i.e. doing prototypes and experiments like the OM Beagle Hybrid, 
doing PCB layout) to be sure that it *can* be done. Really building such boards 
will still cost a significant amount of money (for paying components, 
professional PCB manufacturing and SMD soldering) and time (therefore: my 
question how long you would wait).

> I'm willing to wait a couple of years at least.  And the 500 Euro number that

It will definitively not take several years.

> people are throwing around seems OK.

To finance the next phase, we are thinking about asking for donations or to 
hold an auction for the first 5 or 10 prototype units. What would you think of 
such an approach?

Yes, that is the idea. More information (e.g. complete feature list) and 
openness (as suggested by arne anka) is to come soon. Please watch out for 
announcements in the next couple of weeks...

such a thing is quite unlikely to expect from any large phone manufacturer. 
Even if they open up an existing design. They ususally squeeze every bit out of 
the design to reduce manufacturing cost and may have very special test 
procedures. And they may change internals every now and then to improve their 
production process. I.e. you may get version B4 this week and someone else 
version C7 in two weeks with differences in the not-documented area.

So we have to design a new GTA04 ourselves and add "hardware extension pads" to 
the requirements list...

If a new Openmoko phone is based on the OMAP3 like the BeagleBoard, there are 
at least 3 different Android ports (in addition to anything else like SHR, 
QtMoko, Debian, FreeBSD, ...). One of them is Rowboat 
(http://code.google.com/p/rowboat/wiki/BeagleBoard).

Another project just today announced this on the beagleboard.org list:

If someone wants to try and/or help one of these projects to support a

Hi Steve,

there are different opinions if the 80 char line wrapping of mail is standard 
or some
old-fashioned relict from the 80ies. I have tried to find out what it is but it 
appears
to be a problem with some MUAs not correctly handling RFC 2646.

Here is also some discussion about mailman being responsible or not:

http://www.mail-archive.com/mailman-us...@python.org/msg49755.html

which says:

The problem is that prior to Mailman 2.1.10, the format=flowed and
delsp=yes parameters were not preserved in the outgoing message.

I think the OM list uses version 2.1.9  so it could be a bug.

I don't know if my mail client uses these paramters - but it does not have
an option to do line wrapping when sending.

So, wouldn't it be simpler if you reduce the width of your display window?
Your client should then wrap long lines.

BR,
Nikolaus

PS: I have tried to format this mail manually, but it is quite a pain...

Unfortunately this is beyond what we can provide.

The trick to build such an upgrade-board at a fairly
reasonable price is to use some halfway (at least AT
commands and interfaces) open and precertified 
UMTS module. Part of this certification requires that
it is not possible to change IMEI :( Please view the
concept as a (more or less closed) UMTS stick/key 
with USB interface soldered onto the main board like
 in all the 3G-Netbooks floating around.

For providing such a feature we would have to design 
and certify our own complete UMTS system. And that 
is the million $$$ effort large handset suppliers can afford.

It has turned out that there are currently only two such 
modules that are small enough to fit into the existing 
plastics. One comes from OPTION, the other one from 
Ericsson. Both still have unfortunately some NDA 
limitations - but we are working on it.

BR,
Nikolaus

I agree that we should not spam - but IMHO this was raised as a serious

I could live with the idea that everyone uses a MUA that can
wrap lines when reading and displaying long lines. But it appears there
are systems out there that can't (which I did not yet know). 

And I am asked to solve their display problem on the senders side (although

Before we start fingerpointing on any client we are using, let's do a little 
more research.

http://mailformat.dan.info/body/linelength.html

quotes RFC 2822 (the successor to RFC 822):

  "There are two limits that this standard places on the number of characters 
in a line. Each line of characters MUST be no more than 998 characters, and 
SHOULD be no more than 78 characters, excluding the CRLF."

I.e. lines more than 78 characters are *not* forbidden. From this I conclude
that a mail recipient must cope with that. If not, the client is broken.

And, I conclude that it is not a rule for writing or displaying mails - just
for transferring them over SMTP without making buffer overflows.

Now let's look into the plain code my MUA is sending. Here is an example:

> Hi Steve,

So Apple Mail *is* correclty sending wrapped lines according to RFC.

I do not excactly know what the rules are to interpret the = signs at the
end of the line. I guess it has to do with 

Mime-Version: 1.0 (Apple Message framework v1081)
Content-Type: text/plain; charset="iso-8859-1"
Content-Transfer-Encoding: quoted-printable

A little more search shows this comes from RFC 2045 (MIME) on page 19 (Soft 
Line Breaks).

>From this I conclude that the mails my client sends are correct (according
to the standard).

So it appears to me that we are trying to treat a corectly implemented
feature as a bug because there is some habit of expecting that lines
are always *displayed* with wrapping (even if they are sent as non-wrapped
lines using MIME quoted-printable). But I may be missing something.

If somebody can point me to the RFC that *requires* that lines must
be *visibly* wrapped by the sender so that no client ever shows
long lines, I am happy to file a bug report for Apple Mail (wouldn't
be the first one :).

If there is no such RFC, please report bugs for your clients that
don't wrap long (MIME encoded) lines they receive to the width of
the display window.

I.e. I would not take it as a *requirement* and it is also quite old to stick 
to it.
It appears to be stimulated by times where 50% of the Internet users did
use a VGA screen and 95% dial-up modems. People did not have many
WYSIWYG systems as mail clients. Most mail clients were VT100 compatible.

So I fear I can't convince Apple with this (it does not even convince me...).

The only solution is, that I promise to try to press the return key every now 
and then (unless I forget)...

I completely agree with that. Newspapers come in columns. Since they
were invented 200 years ago. For good reasons.

But I did not expect that any mail reader could have such a problem formatting
long lines to read in small columns. IMHO any modern mail viewer should be
able to do that.

I have checked what mutt is and I am impressed what can be done with the
VT100 methaphor. But it looks as recommending to replace a Porsche by a
refurbished truck because it is more flexible...

One thing made me wonder. Did you correctly use all mutt settings? I have
e.g. found:

If I understand that correctly (I have never used or configured mutt), it
is just a matter of correct settings on the receiver's side and the 'reader'
component.

But let's stop this discussion which is quite philosophical/fundamental
(in several aspects) since we have found a simple solution after knowing
the problem.

The devroom last (ahem, this) year was really successful. I had made

Openmoko Beagle Hybrid - was: [Community Updates] 2010-08-01 is out

[Dr. H. Nikolaus Schaller]

Hi,
you may wonder what has happened to the Openmoko Beagle Hybrid [1] mentioned
in the August Community update (cited below).

First of all we had some delay with our SMD assembly company. They had holidays
on one hand and more work than expected (economy appears indeed to flourish
again). But now we have 10 kits available to find a new home.

And we received a BeagleBoard XM some days ago and started to test the OM 
Hybrid.

We found two major issues so far:

1. the BB-XM already comes with connectors soldered to the board.
Unfortunately Murphy's law did hit us and the BB-XM uses the opposite gender
as our approach for mounting to the BB-C4. 
We now have to adjust for that (by finding a simple adapter solution).

2. the BB-XM uses a different version of the bootloader that is not
compatible with our own code extensions [2].
So we have to fix that so that our SD card image works on the both, the 
older BB-C
and the new BB-XM.

Why is the BB-XM important at all, considering that the BB-C4 is still available
and a little cheaper? Well, the BB-XM comes with a new DM3730 processor
(1 GHz ARM Cortex A8), has a built-in USB/Ethernet hub for 4 ports and a 
built-in RS232 converter. This makes it even more simple to experiment with
Bluetooth, WiFi, UMTS sticks connected to the Openmoko Beagle Hybrid
while still having a portable design (using an external battery pack) to do
experiments.

So we work on these issues and just need some more days to solve them.

Nikolaus

I have good news to announce. We have again made progress
towards our goals.

The first step is that the Openmoko Beagle Hybrid [1] (which is our
experimental and development prototype of such a new Openmoko)
is now working on the BeagleBoard XM [2]. We had to find a new
solution to solder the connectors (since the BB-XM already
has some). And to do some minor software changes to U-Boot. But
now it works.

Here you can find some photos of the assembly process:

http://projects.goldelico.com/p/ombeagle/page/ConnectToBeagleboardXM/

We now have a 1 GHz ARM Cortex A8 with 3D Video behind
a Freerunner touch display!


And there is also good news for the GTA04 OMAP/UMTS upgrade
board. We have finalized the PCB layout and ordered (thanks to a
bigger donation) 10 sample boards and a SMD stencil. They will
arrive in 2-3 weeks. How it could look like is shown here (showing
a 2-layer mockup board and some of the core components):

Not directly. We hope they can become more involved
in the future, e.g. as a distributor for Asia (the project is
run in Europe) or when we really reach mass production.
For development and producing small quantities it is
easier and less expensive to have all people in one place.

For the hardware, we have to test the PCB and see if it smokes or the
Tux smiles on the screen. Then, we have to get RF certifications
and get components for building more than some samples.

It is still a long way to go.

Software should be quite less challenging. We have Debian Lenny
running on our demonstrator (i.e. with kernel drivers for display and
touch screen). So distributions like SHR and QtMoko should be
available right from day one (even before?).

Nevertheless there are many areas for experimenting with software:
* WLAN, Bluetooth
* use the built in sensors (compass etc.)
* make the audio subsystem work to allow phone calls
* etc.

The OMAP uses the Package-on-Package concept so we can install
different memory modules depending on what we want, what is available
and what it costs. There are chips with RAM only and chips with RAM/NAND
flash to choose from.

But we will have at least 256 MByte (I think there aren't any smaller chips).

The OMAP CPU is much faster and many interface controllers are also improved.
And, we know that fast boot is possible. At least someone has done it for the 
Beagle Board:

http://swiftbeagle.googlecode.com/files/beagleboard_project_hui_keji.pdf

They claim that they have achieved 3 seconds from power up to login: on
the serial console. Well, running X11 also needs some time.

That is true. Therefore we leave such optimizations to the software
community. I could imagine a simple and small distro that only allows
to make phone calls but boots in <10 seconds. And a full desktop-like
PDA/Smartphone that takes 60 seconds for the GUI to appear.

Regarding memory we currently plan to use this memory chip:

Here I have found two videos that demo the boot and graphics speed of
the BeagleBoard (which uses the same SoC as the GTA04 will have):

Ubuntu, Angstrom, Enlightenment:

Re: Testing freerunner's audio quality

[Dr. H. Nikolaus Schaller]

Hi,
the problem is the bass. Initially, It was difficult to hear differences
by playing two sounds one after the other. So until you have listened
music on a bass fixed Freerunner, you would say it is quite ok.

I was only able to hear the difference after taking one original Freerunner
and one with Bass-Fix applied. After a while you get that there *is* a
difference in low frequencies.

What I have done is this test: create a sinus sweeping from 10 to 100 hz.
Without bass fix you can't hear it before it comes to the 50 hz range.

sox -n -t wav - synth 10 sine 10-100 >file.wav

This can be seen on scope outputs as shown here:

http://freeyourphone.de/portal_v1/viewtopic.php?f=20&t=1723&p=17279&hilit=bass+fix#p17251

Can you please compare you device?

One effect may also be the input impedance of your line card. Did you connect
it in parallel to a headset?

BR,
Nikolaus

Sounds good to me.

As far as I understand the policy of the Devroom decisions they favour
more general topics instead of single projects (although there are some).

If I look through the list of topics, there should be a little more focus on
hackable *mobile* devices (there are routers, embedded boards etc.).

Also note that there was an "Embedded" Devroom collecting a lot of
different topics every year (I think in 2007 Sean's presentation was part
of that). See: http://archive.fosdem.org/2010/list-devrooms-their-call-talks

"Embedded / Mobile (contact email)
The embedded/mobile room is the place to be for people with an interest in 
everything small, hidden, with different CPU's and/or a gadget or mobile device.
Here we discuss and present things like hacking your phone, PDA or router and 
everything about cross-compiling. The people that gather here are usually doing 
tons of cool stuff with small low-powered devices, from playing music to 
controlling big and complex systems."

So we must somehow differentiate from that or we simply get merged.

Re: We can have Help from Always Innovating !

[Dr. H. Nikolaus Schaller]

Hi,
looks like an interesting project to build a wireless MID.

I want to suggest that you base your design on the GTA04, since it is far more
developed as you might think, but also far from being complete... Let's say
it is in the middle of the ocean but heads towards its destination.

We are currently redesigning it a little so that you can not only use the GTA04
board  as a new motherboard for the GTA02 plastics, but also as a module to
attach a different LCM and other peripherals (e.g. QWERTY keyboard controller).
This is done by adding two board-to-board connectors on the display side.

The UMTS solution of the GTA04 is based on the OPTION GTM501.

On the software side we have Debian Lenny (which can be the base of QtMoko).
There are also Android ports and SHR should not be too dfifficult to adapt.

If you need more information or help, please feel free to ask.

BR,
Nikolaus

Thanks!

It is like starting a new branch of the next "unstable" version of Debian.
Needs a lot of work and time to get it through "testing" to "stable".
So please don't expect results soon... The GTA04 will be finished before.

We will report from time to time what we have achieved.
The first step is to await that the PandaBoard arrives :)

Well, it is the second step. The first is to study what we will get:

Very likely.

I don't know but would doubt it from theory.

Antennas on GSM base stations don't have a half-spherical characteristics
but try to bundle the transmitter's energy to a location where it is
needed mostly. And that is on earth's surface.

But that could be part of the experiment. Just log the list of GSM base stations
found. And add a Freerunner Navigation Board to get barometric altitude. So
you can see at which altitude which signals can be received.

> Has anyone ever tried video streaming from the FR?

The first questions is how to connect a camera.

Today, we received the first PCBs for the GTA04. It has passed a
mechanical test (just some connectors and buttons mounted) and this
bare board fits exactly into the GTA02 case.

Next, some chips are soldered and we do measurements. Before
we solder the more expensive components (CPU, UMTS module).

We not only plan these upgrade boards but also complete phones as a long term
goal. Maybe, even in a different and improved industrial design. And in some
years with a OMAP4 :)

Our team is currently evaluating options (3D printers, rapid prototyping, 3D 
cutting,
protomold, etc.) and trying to build prototypes, but did not yet come to 
conclusions.
So please give us some more time.

Well, it is "only" adding some minor components to the kit (antenna, battery, 
USB-charger,
vibramotor, earpiece, speakers) plus a set of plastic parts.

But plastics is quite a heavy challenge if you really want to do it without big
venture capital. Even larger than getting the PCBs shown in the photos...

The problem appears to be that the inexpensive rapid prototyping methods don't
have the required precision (0.1 mm, 0.5 mm wall thickness, etc.) and those 
with high
quality are prohibitively expensive.

Unless you, i.e. the community, is willing to do fixed pre-orders for a total 
of at least
1000 units.

The idea of having the community design different cases for the Neo 1973 and
Freerunner is quite old [1], but I think there was only one group to show up 
with
a "case extension" [2]. This can be printed e.g. at Shapeways but is not stiff 
and
precise enough for daily use.

Yes, but *very* limited quantities...

And no chance to produce more. I did discuss with Sean how we could get
access to the original tools for community use, but there are financial,
legal, bureaucratic and many other issues. So we decided not to put too much
effort into that aproach.

We know the suppliers and part numbers of all these things
(thanks to the GTA02-core project!) but that does not necessarily
mean that the parts are easy to purchase. But plastics was an
individually produced part.

I have asked them for a quotation (using STL data). Independently of
the resulting quality we have to expect that a single set of plastic parts
costs more than a complete Freerunner...

So it confirms (again) our observation that all rapid prototyping methods
are too expensive.

I.e. we have to get quantity, i.e. enough people who clearly want a (new)
case. This is more about revitalizing this community, and creating new
hype for completely free and open smartphones.

Ideas?

Generally yes. If we sacrifice quality, ergonomics, and size, we can
find simpler and less expensive case constructions.

One aspect to keep in mind for precision are the push-buttons (AUX and Power).
The buttons [1] are specified for a "Travel 0.3 mm +0.1 –0.2 mm". I.e. if we 
don't
want that the buttons get stuck we come to this 0.1mm precision. We have
experienced the same with the PCB design where the position of the buttons
must be within these 0.1mm...

The same is with mounting the display. If that is not precise enough, touch 
operation
will be deteriorated.

So if we reduce precision of the case production process, the buttons become
larger and finally, the phone is more a brick than a handheld phone :)

Personally, I am in favour of high-end high-quality design (like the iPhone)
even if it costs money. But it should never cost freedom and independence...

It comes with a OMAP3530 [1]:

ARM CortexTM-A8 Memory Architecture:
–   16K-Byte Instruction Cache (4-Way Set-Associative)
–   16K-Byte Data Cache (4-Way Set-Associative)
–   256K-Byte L2 Cache 
•   112K-Byte ROM
•   64K-Byte Shared SRAM

If you want to start to experiment with this CPU today (and not wait
for the GTA04), I suggest to get a BeagleBoard + our Hybrid Board
(Touch-Display + GPS).

The perceived speed (not a scientific measurement) is factor 10 faster.

Best regards,
Nikolaus

Well, we have anlysed approx. 5 or 6 different methods and none was inexpensive
for low volumes. The only one that came down below 50 EUR per case is
injection moulding.

But I would be happy if you can guide the GTA04 to a different approach.

Well, the current board is really mounted by 2 torx screws and the connectors
which fit into holes on the sides. The hooks and clips are not really necessary,
which allows for a lot of simplifications. This is where some of us are 
currently
working on to get the plastics produceable by a RepRap.

If I understand correctly, then the button would not fit smoothly into the case.
It may stand out (or in) so it either gets trapped in the gauze of your trouser
pockets, or you need long fingernails to press it.

Not completely. The power button must be a mechanical button to wake up the
processor from deep sleep. Or we drain the battery for a always-powered sensor 
chip.
And, I am not sure if a sensor contact is safe enough for a smartphone in a 
pocket.

The main thing is that the display bezel must be plane. Otherwise it may
press on the display (touch) at one end and increase the risk of breaking
the display glass. Or you get dust inside the device.

On the other hand we know that the bezel of the Freerunner is already too thick.
I.e. for better operation it should be much thinner. But still stable.

Well, all this can be improved by changing the construction.
