Yes - Only 30 shopping days until Halloween
Since I posted a link to our Halloween LED suit and promised updates, I figured I would add a post here in off topic for that purpose. Right now the suit is run on an arduino but I may end up controlling with a FEZ Domino for USB host support. The air joystick works using the normal joystick class so it may be cool to add a USB joystick suit blaster - freegin easy thanks to you guys. The hardest part is I have some pretty complex C++ stuff happening that has to be ported to run FEZ only. I may just cheat and use I2C to have the FEZ read the joystick / other device and send the commands to the arduino. Seeing how there is only 30 shopping days left and I think that robot may want some pants - have to set priorities.
In any event - sometimes powering a suit like this can be 1/2 the battle. Last year our prototype 20 LED suit was tossed together using a 12v lithium ion battery and a 12V inverter - not very efficient. This year we updated the system to use the same 12v battery but instead we used 4 1.2 amp 5v car chargers. No heat and the solution seems to be working well. A small 12v battery powers the suit for an hour on full bright color cycle. It runs longer when playing with the music as the brightness bounces and hence uses less power in the troughs. The battery charges in 30 minutes - so this is the best weight / price / performance power solution I have found yet but open if someone has ideas :).
Here is a video of this years suit finally going mobile with power and microphone.
