more XYZZY motor controller pictures

In honor of the most popular post on my blog in 2010, I’ve decided to upload a few more pictures of the XYZZY motor controller prototype. This time they were taken in high resolution with my new digital camera.

I still haven’t done anything new with it. And technically it’s still unfinished. But, i consider it a partial success anyway. Well, Enjoy.

p.s. here is a nice short article that describes the basics about H-bridges. I especially like the part at the end when it talks about the brake mode. Very useful feature on large robots or even an electric tractor. Here.
