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.

How To Use A Tiny OLED Screen with RetroPie

There’s not much documentation on how to use a tiny OLED screen with RetroPie, so in this video, I’ll walk through the process of setting up one of Adafruit’s teeny-tiny OLED screen modules with a Raspberry Pi Zero.

Hallmark Donkey Kong Ornament Teardown

In my quest to make the World’s Smallest Donkey Kong Arcade Cabinet, I needed to tear down the 2018 Hallmark Keepsake Donkey Kong arcade cabinet Christmas tree ornament and see how I could use the shell to house my electronics. In this video, you’ll see the complete process (including a lot of trial and error) as well as what makes this “magic” ornament tick!

They’re sold out from Hallmark, but you can try the usual suspects:

How To Set Up a Raspberry Pi as a NOAA Satellite Receiver with RTL-SDR

For Project TIROS, I’m building a briefcase-style NOAA satellite receiver using upcycled parts centered around a Raspberry Pi. In this video, I will walk you through the process of installing the necessary software components to use the RTL-SDR module on a Raspberry Pi for NOAA satellite reception.

The Most Useless IoT Device Ever (Part 2) [OUTTAKES]

Clem Mayer challenged me to add more useless “functionality” to the “Most Useless IoT Device Ever” on Element14 Presents. I picked up these bits from the cutting room floor, dusted them off, and present them to you now.

Newark TC-110 Tool Case Unboxing and Review

The Duratool TC-110 tool case from Newark element14 is a great, inexpensive, heavy-duty case for transporting small hand tools and test equipment. It’s made of a lightweight MDF shell coated in textured, heavy-duty ABS plastic and accented with brushed aluminum on the corners to provide extra protection against bumps and dings. Inside, there is a large cushion of perforated foam that can be cut to custom size and shape for any variety of instruments while the lid is complemented by a solid piece of egg-carton foam and a removable pallet for small hand tools. For the price, it may be one of the best tool cases on the market!

Unboxing The Most Useless IoT Device Ever

Clem Mayer challenged me to add more useless “functionality” to the “Most Useless IoT Device Ever” on Element14 Presents, but the IoT Rock had to get from Austria to California first!

These are my initial reactions to the Cold War-themed care package my European colleague sent me!

Element14: Twilight Zone Prop Replica

Matt is a huge fan of the Twilight Zone, so for Halloween, he’s decided to build a classic prop from the old series with a modern twist! The original Mystic Seer was a coin-operated fortune telling machine created for the 1960 episode “Nick of Time”. Will this new, electronic fortune teller actually predict the future?
