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.
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!
