One of my lockdown projects was to make my sit/stand controller smart. I used a Raspberry Pi to create a custom controller that could control the motor on my desk and allow me to rise and lower it over the network as well as via a touch-interface.
Using off-the-shelf parts with a Raspberry Pi, you can make a remote controlled power switch to turn appliances on/off. I’ve used this approach to create Twitter controlled snowblowers, remote controlled car headlights, a Twitter activated Christmas trees … the possibilities are endless. This post will show you how to set up a power switch that will activate when a certain hashtag is posted to Twitter.
