Re: Happy New Year!

[Ranjan]

What would be great is if we have a TV out and an HDMI out from the phone
with two USB sockets so that it can also be used as a generic computer.

We wish you the same Dr.Schaller. We thank you for keeping the project
alive and taking it to the next level. We hope a more powerful version of
the moko is launched which will enable people to experiment with the next
generation of high speed graphics, UI, games and even computer vision.

Re: Discussion: what are your dreams for the Openmoko Community

[RANJAN]

Hi,

I would like to think about it from the perspective of designing a new
device. Let us say the device is more like a wearable wrist computer with a
Flexible OLED or Eink screen. It can have an additional wireless
computational unit that fits in the users pocket.

Immediately ahead on a short term I think the next big product by openmoko
could be either an open source table with enough RAM and GPU that graphic
UI handling is good and the next would be a smart programmable watch
computer. I especially think that the watch computer should cell like hot
cake..

Another idea is to have windows 7 capable hardware.

Cant get gpsd to work

[RANJAN]

Hi,

I am not able to get GPSD to work. I did this:

echo "GPS_DEV=\"/dev/ttySAC1\"" > /etc/default/gpsd
/etc/init.d/gpsd restart


but when I do /etc/init.d/gpsd it says not found. I can see the gpsd file
in /etc/default folder but no use. Is there a script to get GPS position
say lat and long on FR? Please let me know.

The idea of making the MOKO tab

[RANJAN]

Hello All,

Just got an Idea. I think we can make a Moko Tab (an open source tablet
phone/PC) from the existing opensource hardware and the ones related to
GSM,Wifi,bluetooth from OpenMoko FR.

Take a look at the parts that you can find.
http://imgur.com/NCkp9

References:
Modular sensors for the Moko Tab
http://www.sparkfun.com/products/10724

http://www.raspberrypi.org/
http://www.raspberrypi.org/wp-content/uploads/2011/07/pcb1.jpg

The rest of the hardware can be taken from the previous moko. I think the
idea of the first truly open source tablet PC should be realized.

Yeah figured that out eventually. In the future version they should make
the GPS detachable and make the revision more modular like Clip on PCB
boards for Accelerometer, GPS, Barometer,Gyro,SIM card module, etc.. It
would make it more reconfigurable and open source/ DIY.

Open moko GPS pin connection

[RANJAN]

Hi,

Does any one know about the OpenMoko GPS chipset pin connection. After I
opened it I could find only one grey wire which appears to be the antenna.
Where are the Vcc,Gnd and Rx-Tx pins?

Re: [GTA04] When is the next and more powerful openmoko releasing

[RANJAN]

Hello,

Recommendations for better hardware on Openmoko.

1)A 600 Mhz processor is minimally required to run the OS at usable
speeds.An 800 Mhz processor would be good across all OSes.A 1Ghz processor
would be too costly
2)Please use ADXL335 accelerometer whose sensor output is better, less
noisy, smooth transition and will be better to develop applications.Also
please provide a direct access to ADC read from the processor and not a text
file dump and then read method.
3)A tilt compensation 1 axis or 3 axis magnetometer would be good.

With a better processor speed there is no turning back for Openmoko.

Sriranjan

Re: RTK-GPS with freerunner: decimeter-level accuracy with Free Software

[RANJAN]

So I have been working with this:
http://www.sparkfun.com/commerce/product_info.php?products_id=8266

Can two of these chipsets or one with an FR give a decimeter accuracy? The
chipset says it supports DGPS. Or one specifically needs a receiver with
phase and carrier information in the raw data..

Hi,

Was able to remove the LCD from the metal sandwich kind casing.But there are
two cords (highly delicate and flexible) which run from the LCD to the
mother board.One is shielded with some sort or metal tape which I did remove
and the other is glued.

Please advice.

So can the selectivity be changed on the FR?And can the sample rate be
changed as well?Even if one is able to change the sample rate can one read

Hi,

What are the accelerometers used in the FR (company and model number)?I
think it might be Freescale's MMA7260.If it is it has selectable
sensitivities in the range of +/- 1.5 g to 6 g what has been selected in the
free runner.What I observed is that the Free runner is able to detect shocks
as in if a person is running it will work well to detect such shocks.Also if
one has to use it to shuffle songs it will work well.

Please let me know.

I think at 38400 it is not pretty real time.What could be the maximum

Hi,

Can I use this to forward the 2947 port from Neo to 2947 on laptop ,in other
sense can I get the values being generated from Neo at 2947 of Neo be
available at 2947 on the laptop.

Please advice.

Well there is only information about reading NMEA using the older gpsd but
not the fso-gpsd.And in my FR I could not find the folder /tmp/nmeaNP.

Re: GPS NMEA sentences over serial port

[RANJAN]

If you really want to forward serial port, you can use socat for that.

So how shall I proceed in Win Xp.My SHR DISTRO got spoiled,I tried
installing GCC and now the setting fails to lead .So I might have to
reinstall SHR and then do it.But Gpsd is still working good.

Please advice.

Screen in FR goes black and white after resume from suspend

[RANJAN]

Hi,

The screen in my FR goes B/W with weird lines after it resumes from
suspend.Got to know it is WSOD bug (or sometimes resumes in grey scale mode)
.Well temporarily I can change the FR not to suspend but I have to do so
after every reboot.Any solutions?

Free runner doesnot power up

[RANJAN]

Hi,

I have not been using my free runner for about a week.I tried to turn it on
by pressing the power button but it does not.I have plugged in the Charger
and pressed the power button but still it does not turn on .I even tried NOR
boot with Aux and power button but still it does not turn on.Is it that the
device is dead or the battery just need to be charged for some hours before
I can use it again?

Please let me know.(It is chaos for me right now).

Thanks and Regards
