Version 6



    As we know, Matt is a sucker for retro novelties and amusement devices, so for Valentine's Day, he wanted to pay homage to the early days of the arcade with a "love tester" device. This Arduino-powered novelty determines a couple's attraction to each other by measuring the electrodermal activity between them and presenting a readout that borrows design cues from the legendary Nintendo Love Tester as well as so many blinken light-and-bronze-bedecked wooden cabinets dating back to the heyday of the penny arcade
