Kid-Friendly Electronics Teaching Supplies

Wago 222-Series Electronics typically means soldering.  Soldering means highly stressful training using soldering irons with parental-hands hovering inches from child-hands.  Cords everywhere for soldering irons, lead free solder, fume extraction.  All of which is mostly impossible with any size group. Turns out we live in a fairly modern time. We can connect wires with tiny… Continue reading Kid-Friendly Electronics Teaching Supplies

Servo Triggers – Quickest, Fastest, Easiest way to make your servos dance

What’s a Servo? Servos are a fundamental building block of all mad-scientist laboratories.  These little guys will magically move to a position of your choosing, and stay there. As stated by Servo City: As long as the coded signal exists on the input line, the servo will maintain the angular position of the shaft. …… Continue reading Servo Triggers – Quickest, Fastest, Easiest way to make your servos dance

The complete guide to enabling speech recognition on an RPI3… in NodeJS

One of the things a good magic wand should do is respond to magic incantations. This guide will take you through getting Google Cloud Speech APIs functioning on your Raspberry PI 3 so that you can trigger speech recognition through a button press on your magic wand. The Microphone… Before you can get speech… you… Continue reading The complete guide to enabling speech recognition on an RPI3… in NodeJS

[BROKEN]Turn on a lamp with a gesture – IR Cam Image Processing!

Make has a write-up on wand-control with a simple reflective wand. But… I just worked through it… its *way* broken.  The git pull brings down the source with improper tabs and spaces.  Also, its specific to python 2, as the print statements all have to be replaced.   For now – turn back.   Check it… Continue reading [BROKEN]Turn on a lamp with a gesture – IR Cam Image Processing!

Raspberry PI Controlling Power through GPIO (no wifi needed)

Digital Logger’s IOT Logic Outlets In my previous two articles – we show two ways the Raspberry Pi can control power through Wifi: Raspberry PI for controlling TP-Link POWER Raspberry PI for Controlling Wemo Power These assume wifi-enabled outlets, which are great, but there are some cases where you really want the Raspberry PI to… Continue reading Raspberry PI Controlling Power through GPIO (no wifi needed)
