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
What is it? Slither.io is like the original game, Snake. The way you get on to Slither.io is either, by looking it up on Google Chrome, or Safari. Once you look it up, and press enter. You should come to a page that says “slither.io” and has a small purple area that says “nickname”.(Another screen… Continue reading Slither.io – The most well known of the IOs.

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
I’ve covered this in several other articles as a side effect of getting those higher level goals complete. But given a simple Google Search failed me… here is this in case someone else needs it. When you just want: “Raspberry PI3 NodeJS GPIO Control” – this is how you get it done: npm install –save… Continue reading Raspberry PI3 NodeJS GPIO Control: rpi-gpio
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!
