An unusual project this..
As a group of new media atists, we make very large sculptures, usually in public spaces. A few years ago, a high profile client commissioned us to make a sculpture for them. Each element of the sculpture uses embedded Atmel (Atmega 8) processors to control motors and other feedback mechanisms. We need to update this code with some modifications, and then reflash each Atmel chip with the modifications.
We have the original C code that was used, to make life easier. If you are interested in this, and have experience with Atmel chips and programming them, please let us know! We can supply everything thats needed to make life a little easier..
