The Pandora connectors and the Beagle Board connectors are *very* different. So I see the only method to connect the Beagle to the Pandora is through USB.

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.

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.

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.

Well, I reflow soldered the HMC5843 which is a 0.5mm pitch QFN. The steps are rather simple: - get a good PCB with the right footprint and soldermask - if you want to use solder paste, just apply an amount on the pcb and melt it with your solder iron. This should result in small dots of solder on the PCB. It's like a BGA, but with the balls mounted on the board. Working with solder paste but without stencil mask won't work for fine pitch applications. Just use normal solder wire for this task. It works equally well. - flux should not be necessary, but YMMV. - carefully place the QFN onto the solder drops. Make sure it aligns with the pads. Very small alignment errors will automatically be corrected during the reflow process. - place everything in your oven - recheck the alignment - heat the oven up until the solder melts. I used a piece of solder wire next to the board to see if the melting point was reached. - switch the oven off when you think it's done. The extra solder wire should look like a ball now and the chip should be sunken onto the surface of the PCB. Don't wait too long! That's it! good luck!

Re: [gta02-core] Openmoko Beagle Hybrid
Hi Nikolaus, Very good stuff, an open phone with OMAP3530-Power, my dream... I am a little off topic here, but I take the chance to ask eitherway. I am thinking about a little simpler NaviBoard. The actual Naviboard has 2x2 ADC with I2C and one 2axis Gyro(analogue) and one 1-axis gyro(analogue). A few weeks ago Sparkfun announced a new 3-axis gyro with I2C (IDG3200), which would make the Naviboard much simpler, I guess, and give the chance to add the pressure sensor (BMP085) to the PCB. I have one of these gyro on a breakoutboard in my hands, the chip is really tiny with a tiny tiny footprint. I think I will be able to solder the pressure sensor with a reflow oven in future (when my reflow oven is finished), but this gyro and the honeywell mangneto sensor. How do I solder them? How do I apply the solder paste to such a fine grid with no special epipment? You said, you also have at least one chip with BGA (0.5 pitch I guess) on your board, how did you manage to solder this during prototyping? Any tipps? Anyone?

We have done some research and asked for quotation and the result is that if you want to get below 50 USD per unit (which is still a lot of 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...

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 :) > The issue then becomes access to equipment and experience.

Low-volume injection molding should be quite affordable if you provide the cast (aluminium) or at least a machine-ready design. Of course, if you have to pay for the entire design work too, things will get expensive. However, you may also want to consider making the parts directly, without going via a cast. This is much more expensive for larger quantities, but if you only need a handful of cases anyway, it should be more efficient. The issue then becomes access to equipment and experience.

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.

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...
