Guy Builds a ‘Useless Machine’ and Gives it a Little Sass

Written by


While there are many variations of a ‘Useless Machine’, the general idea is to build a machine that has one purpose, to flip off a switch any time someone turns it on.

It typically involves the use of an Adruino board programmed with some basic commands (i.e., if the switch is on, turn it off!). YouTube user fritend1 took things one step further, giving his ‘useless machine’ a little personality.

You can see some build photos below and if you’re interested, you can view/copy/edit the Arduino code here!
