Constructing residence automation initiatives is a favourite pastime amongst electronics fanatics. Integrating all kinds of good units into one’s residence not solely provides comfort to their life, however it is usually a superb excuse for experimenting with all kinds of {hardware}. From establishing voice-controlled lighting programs to designing safety cameras that may be monitored remotely, the chances are just about limitless relating to residence automation.
In fact, not all initiatives must be fully sensible — there may be loads of room for creativity, exploration, and studying as properly. YouTuber byteMyCache not too long ago developed a house automation system that falls into this class. Quite 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 after they come residence, the wands are little greater than a paperweight. As an inquisitive particular person, byteMyCache questioned 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 Actually, they’re little greater than an outdated infrared tv distant management with a single button.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 thought to construct receiving units that may very well be used to set off actions round the home for his kids. As soon as you know the way the wands work, there may be not a lot to it. The secret is to make use of an applicable infrared receiver — on this case a TSOP4838. That was wired into byteMyCache’s favourite little cheap improvement board that options an ESP8266 microcontroller. For the reason that ESP8266 has an honest quantity of processing energy and likewise a Wi-Fi transceiver, it’s a nice selection to be used in a house automation system.
After soldering the receiver to the event board, the subsequent step concerned establishing the software program ecosystem. House Assistant is a very talked-about 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 software 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 mechanically seem within the House Assistant consumer interface for additional configuration.
As soon as firmware is flashed to the gadget, it may be programmed to take any arbitrary motion by way of the House Assistant interface when it will get blasted with the wand’s infrared sign. To reveal a few of the prospects, byteMyCache confirmed the wand getting used to activate a lamp and a tv, however in fact 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 places in your space, byteMyCache famous that the wands may be bought fairly inexpensively on platforms like EBay. The probabilities for this gadget prolong past residence automation. What would you construct with this wand? Make sure to put up it on Hackster so we will have a look!
If magic wands usually are not actually your model, perhaps you’d fairly slip on some ShAIdes for residence automation?
