Hi, I was looking for a servo controller and found this. I thought others like me would find it interesting to build. However, don't even try doing this if you do not have knowlegde in building circuitboards. It is bassicly a homemade model of Arduinos (don't know how to spell it, I think) made for servo controlling. It can be useful for lots of things, for example to make a robot arm. If you have other ideas, post them in the comments section.
Note - this is the result of my reasearch on USB PC programable servo controllers
Other note- the images are not mine, but I think they might intrest you.
