If you are planning to use the Teensy->Fio board just remember that you’ll need to cut the trace between VIN and VUSB at the bottom of the Teensy. If not, the 5V from the USB could get to the battery and you could damage the battery.
I designed something pretty similar last year, you can look at the PCB over OSHPark.org, in my case I tried to keep the footprint and the pinout from the FIO so it could be used as a drop-in replacement for the FIO v3.3, it also includes a LiPO charger.

I don’t have a way to mass-produce it but is OpenHardware so I can provide the schematics and PCB layout if you wish to carry it out :)
This is a picture how it looks like used in conjunction with a pretty BIG XB900HP with a SMA connector. (Taking it to the extreme)

You are right, my wrong. In you put 4 them in parallel you are going to need at least firstname.lastname@example.orgA, in series 12V@700mA would be enough as you said. Sadly I don’t see a datasheet, may be he can put 3 of them in series and over-drive them a little bit (even reducing their lifetime if the he doesn’t care).
If the forward voltage must be between 3.4-3.6V you can put them safely 4 of them on series, they are going to glow a little bit less but them are not going to require additional wiring. Just be sure that the 12V voltage source can provide at least 2.8A.

I think that the best library for using it with the Teensy is the SmartMatrix. I’ve just tried and it works great. Take a look a it: http://docs.pixelmatix.com/SmartMatrix/

Hi Mike! Here is the link for the translation to Spanish, also I have created an open Google Doc if someone wants to improve the translation. Regards, Mario.
Hola a todos, les dejo el vínculo de la traducción de esta muy interesante y motivadora entrada en español:
Si piensan que la traducción se podría mejorar también les dejo el vínculo a un Google Doc abierto para que agreguen sus sugerencias:
Wow, this is a very good inspirational post. I could identify myself from the begining. Can I translate it to Spanish and share it on my blog? I think that many people here could like it :)

Programming on the Raspberry Pi is always really fun :)
I’ve made something pretty simmilar at the beginning of this year. It’s written on python I called it “rpitwit”, it monitors your twitter account for a keyworkd and executes a command stored on a pre-defined directory.
The funny thing is that it comes pre-configured, ready to use and you can use python or bash scripts. The funny thing is that I wrote it for work with the Raspberry Pi but later I realized that it works on any Linux distribution with Python and PiPy :) I hope that you find it useful.
No public wish lists :(
