Harbor Freight LED Parts Harvest

In this video, we’re going to teardown a few of Harbor Freight’s LED lighting products to harvest the parts for some other projects. In particular, I’m interested in different LED form factors to add some variety to Project Eros, so we will be tearing apart a switch light, a small flashlight, and an adhesive puck light to have at their innards and see what we can salvage from them. Which one will have the most useful parts? The answer may surprise you!

What Is Electrodermal Activity?

Skin conductance, galvanic skin response, electrodermal activity: What is the phenomenon that describes how electricity is conducted across human skin? In this video, we’ll take a quick look at the history and the mechanism of electrodermal activity, how it’s used, and whether we can trust the results. If you want to know how a lie detector works, how a love tester works, or how an e-meter works, then sit down for a quick primer!

How To Build An Arduino Love Tester

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.
