Raspberry Pi 2XL Robot Assistant Part 1 element14 presents  |  Matt Eargle's VCP Profile |  Project Videos   Following up to my primer on using Snowboy for custom Google Assistant wake words, in this video, I'll walk you through using Snowboy's "Hotword As A Service" to train your own wake words.

Raspberry Pi 2XL Robot Assistant Part 1 element14 presents  |  Matt Eargle's VCP Profile |  Project Videos   The new voice assistants like Siri, Cortana, Alexa, and Google (itself?) are becoming more and more ubiquitous as we race toward a "Star Trek"-style omnipresent computing interface, but what if you don't like invoking the name of your chosen corporate overlord when you use the assistant's features? What if you could speak "Okay, Computer" into an Apple mouse like S ...
Raspberry Pi 2XL Robot Assistant Part 1 element14 presents  |  Matt Eargle's VCP Profile |  Project Videos   The Matrix Creator is an IoT-centric development board that comes with a wide array of goodies that facilitate hardware development such as an FPGA, various accelerometer and environmental sensors, IR transceivers, and even an 8-microphone array that can be used for echolocation as well as omnidirectional listening. It's this microphone array that makes the Matrix ...
Raspberry Pi 2XL Robot Assistant Part 1 element14 presents  |  Matt Eargle's VCP Profile |  Project Videos   AI voice assistants are the latest new hotness to come out of Silicon Valley, but before they were in every electronics department, they were much the exclusive playground of the DIY tinkerer. With kits like Google's AIY line, hackers and makers can build their own voice assistants with little more than the good ol' Raspberry Pi! In this video, I'll walk you throug ...
Raspberry Pi 2XL Robot Assistant Part 1 element14 presents  |  Matt Eargle's VCP Profile |  Project Videos   The Mego 2XL Robot is an interesting piece from the very beginning of interactive electronic toys. The 1970s 2XL incorporated little more than a modified 8-track player to provide hours of entertainment on specially-formatted cassette tapes. In this Mego 2XL teardown, we'll look at how the toy was built, the basic working mechanism, and attempt to diagnose a 2XL no ...
  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! ...
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 ...
I am, by no means, a software engineer. My code is crude at best, but it works   /* * Project Eros * CC-BY-SA Matthew Eargle * AirborneSurfer Productions * for element14 Presents * * airbornesurfer.com * element14.com/presents */ #include <Servo.h> Servo needle;   // create servo object "needle" to move the needle // declare global variables const int numReadings = 10; int readings[numReadings];      // the readings from the analog inpu ...
It's a pretty simple vector design for the face of the unit if you want to build something similar. The STL file is for the needle that attaches to the servo motor. ...

  In this video, we'll walk through how to install a TFT LCD screen on on a Raspberry Pi for small form factor or portable projects. This video is an older one that I did for Project Xybernaut, but nothing has changed in the past few months. ...
  For Project Rankin to come alive, I needed it to have some level of audio, but I didn't want to plug some USB solution in or even use the on-board mini jack if I could help it, so I figured out a quick hack to get sound from the Raspberry Pi A+ out to a simple speaker. ...
  Teardown and exploration of how a string of fairy lights/Christmas lights/holiday lights works. Part of the Project Rankin series that intends to build a holiday ornament powered by the AC electricity in a light strand. ...
I needed to pick up some fairy lights for a project, so off to the thrift shop! ...
I can't embed this video for some particular reason, so here is a direct link:   https://www.youtube.com/watch?v=eMlImEE0bUU   As part of Project Rankin, I need to be able to convert 120VAC to a more usable 5VDC, so I'll be using a ubiquitous wall wart. However, I want to keep it as clean and tidy as possible, so I need to wire the adapter directly into the project itself. While I've got the case off, I'll walk through the basic components and how an AC adapter works. ...
