Sigh. This is exactly what you're looking for, methinks: http://meowmeowmeow.bigcartel.com/produ … ammed-chip

This is the one I have. Super easy to make. The only thing you need besides this is a cable. He sells them on his site also.

I've heard of this but never really looked into it.
It looks cccrazy, but expensive:(

sorry, i was thinking about the lsdj mc2 http://www.djtransformer.com/shop/produ … product=15

from where?

you can always buy one

Man... I'd love to have an Arduinoboy.
Too bad I don't have the modding skill or the money.

thanks little scale

Arduinoboys look like fun!

Which parts in particular are you having difficulty finding?
