My (hopefully) epic school project!

I used legos. Simple, motor to turn on. Counter-clockwise = 0 Clockwise = 1.

So you've built one? A little more detail would be appreciated. Pictures?

It was a little while back and I did not take pictures. I simply used a combination of motors and differential gears to achieve it. It was a binary adder and I really could not do much else. I'll see what I can find online.

Edit: This was the closest thing I could find. It uses a simple lever system
