count me in for some soldering and GPIO debauchery as needed

I just ordered one also. Sounds like a fun project. Maybe we need to have a "put it together" party when they arrive?

I've been following this project for a while, their goal is to produce a small ARM board with everything you need to program it built in for only $5 -- the idea being that at that price, you can stick them everywhere and not have to worry about the cost. They are now close to being finished, and are trying to raise enough money to get some prototypes out into the hands of hackers looking to play with them. You can see details on the project here: http://mchck.org/

powerful: ARM Cortex-M4 with DSP extensions, 50MHz, 32KB code flash, 8KB RAM, 32KB data flash

low power: can run directly from a coin cell battery for months

2 microUSB jacks (the boards themselves will plug into a USB port directly, the optional jack allows you to instead use a USB cable)
>I've already ordered a kit, I'm thus spamming you all in the hopes that others will as well and I can get my boards (I have an unhealthy addiction to small inexpensive microcontroller boards)

>Note that this is not a finished product yet -- you'll either need a bit of experience with ARM and microcontroller dev, or be willing to wait to use the boards until they finish all the software and iron out any issues that may arise.
