Constructing residence automation tasks is a favourite pastime amongst electronics fanatics. Integrating all kinds of good gadgets into one’s residence not solely provides comfort to their life, however it’s also a wonderful excuse for experimenting with all kinds of {hardware}. From organising voice-controlled lighting programs to designing safety cameras that may be monitored remotely, the probabilities are nearly limitless in the case of residence automation.
In fact, not all tasks have to be completely sensible — there may be loads of room for creativity, exploration, and studying as effectively. YouTuber byteMyCache not too long ago developed a house automation system that falls into this class. Slightly than utilizing conventional mechanisms like voice, gestures, or a smartphone app for residence management, byteMyCache as an alternative 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 understood 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 singular 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 Actually, they’re little greater than an outdated infrared tv distant management with a single button.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 gadgets that might 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 bottom line 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. Because the 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 following step concerned organising the software program ecosystem. Residence Assistant is a very talked-about free and open supply answer 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 Residence Assistant, and gadgets configured in ESPHome will mechanically seem within the Residence Assistant person interface for additional configuration.
As soon as firmware is flashed to the machine, it may be programmed to take any arbitrary motion by way of the Residence Assistant interface when it will get blasted with the wand’s infrared sign. To exhibit among the potentialities, byteMyCache confirmed the wand getting used to activate a lamp and a tv, however in fact that may be personalized to swimsuit every particular person’s wants.
In the event you don’t have a MagiQuest wand, or any Nice Wolf Lodge areas in your space, byteMyCache famous that the wands could be bought fairly inexpensively on platforms like EBay. The chances for this machine prolong past residence automation. What would you construct with this wand? You should definitely put up it on Hackster so we will have a look!
If magic wands will not be actually your model, perhaps you’d slightly slip on some ShAIdes for residence automation?
