Constructing residence automation initiatives is a favourite pastime amongst electronics lovers. Integrating all kinds of good gadgets into one’s residence not solely provides comfort to their life, however it is usually a wonderful excuse for experimenting with all types of {hardware}. From organising voice-controlled lighting programs to designing safety cameras that may be monitored remotely, the probabilities are nearly limitless with regards to residence automation.
In fact, not all initiatives must be solely 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. Reasonably 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 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 singular wand identifier. Actually, they’re little greater than an previous infrared tv distant management with a single button.
That gave byteMyCache the concept to construct receiving gadgets that could possibly 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 growth board that options an ESP8266 microcontroller. For the reason that 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. Dwelling Assistant is a highly regarded 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 growth boards to be used, and even do over-the-air updates. As a bonus, it performs properly with Dwelling Assistant, and gadgets configured in ESPHome will mechanically seem within the Dwelling 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 Dwelling Assistant interface when it will get blasted with the wand’s infrared sign. To reveal a few of the potentialities, byteMyCache confirmed the wand getting used to activate a lamp and a tv, however after all that may be personalized to go well with every particular person’s wants.
If you happen to would not have a MagiQuest wand, or any Nice Wolf Lodge areas in your space, byteMyCache famous that the wands may be bought fairly inexpensively on platforms like EBay. The probabilities for this gadget lengthen past residence automation. What would you construct with this wand? Be sure you publish it on Hackster so we are able to have a look!
If magic wands are usually not actually your model, perhaps you’d reasonably slip on some ShAIdes for residence automation?
