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

Raspberry PI3 NodeJS GPIO Control: rpi-gpio

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

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

Make has a write-up on wand-control with a simple reflective wand. Check it out – the build is overly complicated – but it’s a whole package 😉 : http://makezine.com/projects/raspberry-pi-potter-wand/ The pearl stickers were hard to find for me.  So I ordered retro-reflective tape: Retroreflective Tape How this technique works… This technique uses image processing to track… Continue reading 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)

Raspberry PI – Run on boot, and run forever! Systemd/Systemctl

The raspberry pi is a cheap linux box you can have plugged in all the time, and they’ll just crank away until the flash wears out… which is likely to be never. Start stuff on boot One of the few things that can get in your way:  power dropping out and causing these little guys to… Continue reading Raspberry PI – Run on boot, and run forever!

Raspberry PI for Controlling Wemo Power

The previous article: TP-Link POWER covered TP-link devices.  They’ve become a little difficult to get ahold of this holiday season, but Wemo devices by Belkin are all over the place. WEMO Switch Outlet So, I took a little time to figure out how to automate those little puppies. Its pretty simple, once you track down… Continue reading Raspberry PI for Controlling Wemo Power
