I’m a bit of a sucker for retro electronic novelties, and one of the most prolific is the “love tester” device that–in various forms–hearkens back to the early 20th century and the heyday of the penny arcade. These were often an electromechanical device that used some algorithm (or even just a random number generator) to ring bells, flash lights, and indicate either a fortune or–more often–a rating of one’s romantic prowess. In the 1960s, Nintendo released their first (in what would prove to be quite a long line) of electronic toys which gave a love rating based on the electrodermal activity between two people. In this video, part of a series building a project for element14 Presents, I’ll walk through using an Arduino to replicate the Nintendo Love Tester so you can build your own meter for your Valentine.
