Well, if it counts, we have a homemade potato grating machine from the Soviet times my grandfather has made because he was a genius and partly because of Soviet Union. It draws a lot of energy, emits a lot of noise (seriously). To turn on, it has two buttons, one for capacitor or something, another for the motor itself and, nowadays, I have no clue which one I should turn on first, left or right… It stands on three legs and weighs around 10 kg (old transformers were heavy). It produces good results, though, despite looking odd.
