Constructing residence automation tasks is a favourite pastime amongst electronics fans. Integrating all kinds of good units into one’s residence not solely provides comfort to their life, however it’s also a superb excuse for experimenting with all types of {hardware}. From organising voice-controlled lighting methods to designing safety cameras that may be monitored remotely, the probabilities are just about countless in relation to residence automation.
In fact, not all tasks must be fully sensible — there may be loads of room for creativity, exploration, and studying as properly. YouTuber byteMyCache just lately developed a house automation system that falls into this class. Moderately than utilizing conventional mechanisms like voice, gestures, or a smartphone app for residence management, byteMyCache as a substitute used a magic wand. Spoiler alert — it was not an actual magic wand, so some electronics wizardry was wanted to make the magic occur.

Nice Wolf Lodge is thought for his or her MagiQuest magic wands that kids can use to play interactive video games throughout their keep. However once they come residence, the wands are little greater than a paperweight. As an inquisitive particular person, byteMyCache puzzled what made them tick. After digging in a bit, he discovered that they’ve infrared transmitters that broadcast a novel wand identifier. Actually, they’re little greater than an outdated infrared tv distant management with a single button.
That gave byteMyCache the concept to construct receiving units that could possibly be used to set off actions round the home for his kids. As soon as you understand how the wands work, there may be not a lot to it. The secret’s to make use of an acceptable infrared receiver — on this case a TSOP4838. That was wired into byteMyCache’s favourite little cheap improvement board that options an ESP8266 microcontroller. Because the ESP8266 has a good quantity of processing energy and in addition a Wi-Fi transceiver, it’s a nice alternative to be used in a house automation system.
After soldering the receiver to the event board, the following step concerned organising the software program ecosystem. House Assistant is a extremely popular free and open supply resolution for customized residence automation setups, and that’s precisely what was chosen on this case. This was paired with ESPHome, which is a instrument that makes it quite simple to configure ESP improvement boards to be used, and even do over-the-air updates. As a bonus, it performs properly with House Assistant, and units configured in ESPHome will robotically seem within the House Assistant consumer interface for additional configuration.
As soon as firmware is flashed to the machine, it may be programmed to take any arbitrary motion through the House Assistant interface when it will get blasted with the wand’s infrared sign. To display a few of the prospects, byteMyCache confirmed the wand getting used to activate a lamp and a tv, however after all that may be custom-made to swimsuit every particular person’s wants.
When you don’t have a MagiQuest wand, or any Nice Wolf Lodge areas in your space, byteMyCache famous that the wands will be bought fairly inexpensively on platforms like EBay. The chances for this machine prolong past residence automation. What would you construct with this wand? Remember to put up it on Hackster so we will have a look!
If magic wands should not actually your type, possibly you’d relatively slip on some ShAIdes for residence automation?
