Re: Metal case [was: Application idea: Bicycle computer]
How about a case that's part metal and part plastic? Make it plastic just around the antennas (which, IIRC are at the 'ends' of the phone) and metal everywhere else? Heck, it could end up having a *good* effect by being extra shielding between the antennas and the (noisy) electronics of the phone itself. --pj On Tuesday, Mar 18, 2008, "Flemming Richter Mikkelsen" writes: >On 3/7/08, Erland Lewin <[EMAIL PROTECTED]> wrote: >> 2008/3/6, JW <[EMAIL PROTECTED]>: >> > Why do people want metal cases so much...???Features in wiki >> > hardware wishlist too. >> >> > My thought is aluminium = metal = faraday cage = stops gps, gsm, wifi, >> > bt signals = BAD idea >> >> The back of the iPhone is mainly metal isn't it?

2008/3/6, JW <[EMAIL PROTECTED]>: > > Why do people want metal cases so much...???Features in wiki > hardware wishlist too. My main reason for wanting a metal case is that it ages better than plastic. I carry my phone (currently a Sony Ericsson P910) in my pocket, and even though I try to keep it separate from keys, coins and other hard stuff, after a while the color gets worn off and it looks really ugly. I want my phones to last for a couple of years. My thought is aluminium = metal = faraday cage = stops gps, gsm, wifi, > bt signals = BAD idea The back of the iPhone is mainly metal isn't it? Many attractive cell phones today have at least parts of their cases made of metal. Also, I read about someone (forgot where) trying to make a Faraday cage, but apparently it is quite difficult in practice. For an efficient cage you apparently need many meshes with holes in different sizes for different frequencies if I recall correctly. I guess this could be easily tested by putting a cell phone in a tin can and trying to call it... IMHO, after FIC successfully releases the Freerunner, they should either get some good designers to design a very attractive case for a next version, or maybe hold a contest among industrial design students to get some cool ideas. The Freerunner is great feature-wise, but IMHO isn't physically attractive enough to sell well in a mass market. By the way, when will the CAD files for the Freerunner case be released?

You would just need a decent sealing/joint around the touch screen. I don't think the touchscreen itself takes any harm from getting in contact with water.

That was my original thought, but then I thought "why not go with something a little more exotic?" The CAD files are out there, all we need is for someone (I've suggested Hope) to CNC a new case for the Neo1973 out of a single block of aluminium that can be bolted to my bike. If they did it right, there'd be no worries about mud, water or damage, just a bullet proof, bespoke bicycle computer. It might not have mass market appeal, but there's plenty of people out there who see a bike costing £1000 as being cheap.

Re: Application idea: Bicycle computer
The Polar HR Monitor equipment does a very simple 5hz pulse that can then be picked up and counted to get HR data.The hardware simply amplifies pluses in the 5hz frequency range, which could then be fed into a General Purpose Input Output (GPIO) line on the Neo 1973 itself. This is great because it's relatively simple to do, and alot of people have Polar HR stuff already. The ANT wireless protocol is used in alot of upcoming bicycling sensor products, Cadence censors, power meters, Heart Rate Monitors, Speed Pickups etc. from a variety of manufactures (Suunto, Garmin, PowerTap, Quarq) It is significantly more complicated since it allows multiple networks of device to interact in different ways without interference. Fortunately most of the complication is abstracted away by the integrated chips that thisisant (parent company garmin) sells. These chips provide just a serial interface, which is publicly well documented that can be used to communicate with these devices. The easiest way to get started is to buy a suunto pc pod, which is a has a USB -> Serial interface that is then fed into the aformentioned chip that communicates to any ANT sensors. I don't know if/how the hardware could be attached to the openmoko platform since I'm not really a Hardware guy, though I suspect you might be able to pigy back on the i2c bus, does anyone know? -Will P.S.

I'm not quite sure how one goes about capturing that. Not sure about the Polar units, but for things using ANT like the suunto cheststraps there are these: http://www.thisisant.com/index.php?section=31 Everything from chips to complete USB sticks. No linux driver for the USB stick yet, but they may be willing to release enough info for one to be developed. USB is probably easiest for connection to the Neo, while the modules should be fine for a wireless cadence sensor. Adding a wheel pulse should be fairly easy if you aren't happy with GPS speed.

You can get receivers for Polar chest straps that signal beats with gpio-accessible pulses. If the Neo1973 isn't completely packed inside, it should be an easy add-on. And Polar doesn't seem to mind other people doing better and cheaper software, so long as it requires buying Polar hardware. -Daniel *This .sig left intentionally blank* ___ OpenMoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

>Would it still be possible to use the touchscreen then? Doesn't really matter since you'll have accelerometers. Give it a light knock to the left to see stat screen X, knock it to the right to stat screen Y, knock it right on to light up the screen. Make it do an automated 911 call with recorded voice and GPS co-ordinates if it detects sudden, strong, acceleration in one direction and then a complete stop. Only your imagination limits you. :) /Oliver ___ OpenMoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
Re: Application idea: Bicycle computer
I've looked into this quite a bit, if you'd like to integrate with a HR Monitor/Cadience/Speed sensor the option that makes the most sense is to use the ANT(thisisant.com) wireless protocol to interact with any of the sensor made by garmin or suunto.Suunto produces a USB->Ant interface called the Suunto PC Pod. I was able to get it to work in linux using the documentation available on thisisant.com a basic proof of concept (that reads the Heart Rate data) in linux is available here: http://code.google.com/p/suuntopcpod/ Since the Neo 1973 has USB Host, you could plug in the dongle and have it working without a problem. -Will On Dec 2, 2007 3:18 PM, Giles Jones <[EMAIL PROTECTED]> wrote: > > On 2 Dec 2007, at 14:41, Christian Surlykke wrote: > > > Hello > > > > I'm interested in using the neo1973 as a bicycle-computer, utilizing > > it's gps abilities. > > > > Any comments/insights would be appreciated.. > > I have a Garmin Forerunner and the battery life is 10 hours.

I wonder if it would be possible to create a wireless interface for these things, or a bluetooth interface for a heartrate and cadence monitor. Actually, bluetooth heart rate and cadence devices would probably hurt polar (the leader in the field) since open source software for these things would be much better than what they produce, and at a far better price.

Application idea: Bicycle computer
Hello I'm interested in using the neo1973 as a bicycle-computer, utilizing it's gps abilities. Garmin makes gps-based bicykle-computers, for example the Edge 205 Gps (http://www.amazon.com/Garmin-Edge-205-Gps-Cyclocomputer/dp/B000RI0E0G/ref=pd_sbs_e_2?ie=UTF8&qid=1196603550&sr=1-3) that sells for ~ $200, so the way I figure, if the Neo had bicycle capabilities, I'd save the $200 for a Garmin, and effectively get a great phone/handheld for $250 :-). That might be a good selling point... So I consider writing an application that can do that. At a minimum the application should be able to: - show speed, average, max, min, distance traveled,.. - show position, (preferably on a map - or at least record positions so that you can feed them into google-map afterwards), elevation, rate of descent/ascent.. Issues to consider: - power consumption. I imagine running the application with a dimly lit screen, perhaps only showing current speed. Touching the screen should light it up, revealing more details. What kind of batterylife could one hope for? - some way of mounting the Neo 1973 on the handlebar. Preferably with some protective cover. Does FIC or someone else sell such accesories? Would it still be possible to use the touchscreen then? - external sensors (cadence, heart rate) Many bicycle computers show cadence and heartrate, based on input from external sensors. Could something like that be done with the Neo? Any comments/insights would be appreciated.. best regards Christian Surlykke ___ OpenMoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
