We present THE ANALOG THING, an open source / open hardware project demonstrating how analog computers work. There is no processor in this board.

Analog Computing is an unconventional computer architecture based on mathematical analogies. It shares aspects with quantum computing (nonalgorithmic, initial state preparation and measurement) but is way easier to grasp. 5mins of your time are sufficient.
