Piksel starts today, and that gave me an excuse to finally post some of the technical info related to the wind-up birds project. Tomorrow I am giving a presentation of the mechanical woodpeckers at the festival.
The first tech-post is about how to program and hook up a atmega168 chip as a minimal arduino standalone, consuming less power and being much cheaper. It uses the internal oscillator running at 8mhz and is powered by 3.3 volts.
I will follow up this in the following days with a post about the xbee-arduino connection.
