That was a huge one. Spintronics - build mechanical circuits. Sure. Wait. What?

Yes, you read right. Mechanical electronics! What Paul Boswell presents on Kickstarter, is one of the projects that definitely deserve backing. Paul built mechanical equivalents not only to basics like switches, resistors, wiring, junctions. There are capacitors, oscillators, a battery and … a transistor! Sounds incredible, he? But is actually true.

To be fair, the available kits target the interested novice, not the established pro. But nevertheless, the idea to be able to test electronic circuits with mechanics sounds intriguing.
