Jumbleview was inspired by the Make Magazine article to build this version of the Useless Machine.  It doesn’t use a toggle-switch, instead it uses two micro-switches and it counts how many button presses take place.  The arm comes out and presses the button the same number of times.

The Machine uses a micro controller called a Pololu Baby Orangutan B-168, which I believe to be very similar to an Arduino.  The source code can be found here.

Unlike the other micro-controller based Useless Machines, this version REALLY POWERS ITSELF DOWN!

I also like how he’s designed the mechanics of the arm.  Great job Jumbleview!
