I started by printing out templates for the front side of each layer (they are all the same obviously) and by buying the materials I needed. I got a sheet of oak (white, 18mm) and Plexiglas (transparent, 8mm). Then I used a table saw to rip it to square that the templates would fit in. Compatible with AirPods, All versions of Apple Watch, Apple Watch Series 3, Series 2 and Series 1, iPhone X/ 8/ 7 Plus/ 7/ 6/ 6s/ 6 Plus/ 5s/ 5c/ 5, iPad mini. A premium headphones holder for both over-ear and in-ear headphones. Then just some weeks ago I stumbled upon the awesome WLED library for driving digital LEDs. It includes everything I need: MQTT and HTTP support, a web interface, color changing and animations. After flashing the software onto the NodeMCU and connecting to it via my phone I provided my Wifi credentials. After getting some strong but small rare earth magnets and doing some tests I decided to give this idea a try. It is invisible form the outside and allows me to easily take the headphone holder off the wall if I have to change something with the lighting inside. Building and sanding

Careful not to remove too much material I used the belt sander to to get everything roughly into shape. Then I switched to 120 grid sandpaper to get cleaner surface. This took a couple of hours but in the end I had to form I was looking for. Then I switched to the random orbit sander with higher grids to get everything nice and smooth.Once I had all the squares in the rough size I needed I glued the templates onto them and started cutting them to form using a jigsaw. Because this will not be a hundred percent accurate I made sure to stay a little bit outside the intended size. I bought a strip with 60 LEDs per meter and and cut up 3 length of LEDs so that each one fits inside the whole in headphone holder. Each is formed into an outward facing ring and I (re)connected them with flexible wires. I also added a small capacitor across the power lines (1000uF) and a resistor in series (470 ohms) according to the official recommendation for Neopixels. The premium quality stands for multipurpose use. And almost everyone will need it for their office & home headphones to keep on their desk. There could be many more devices with headphones on the desk, so it seems very useful to me. Of course this can also be integrated with my smart home system. I already described how to integrate WLED into OpenHab, or pretty much any other smart home system, via MQTT in my article about my smart wardrobe. This is exactly the same process. Before gluing in the magnets I made sure to have them facing the right way so that they actually attract each other. Unfortunately this is where I learned that my first idea was not working.

When all the cutting was done I drilled the holes into every layer excluding the first one. This was done on a drill press. Afterwards I glued together all the layers but the last one. Finally I slightly broke the edges with sandpaper and cleaned everything up. I also tried to get the acrylic parts to a more opaque look to diffuse the lights but that did not really work out. Maybe I could have tried sandblasting but I had no such machine available. Finally I used some oil to get everything finished. Adding the magnet magicI have used it for about two years now and never had any problems with the LEDs, magnets or anything else. This is already the seconds pair of headphones resting on the holder and the shape has worked well for both of them. My custom LED lit headphone holders Then I connected everything to a NodeMCU micro controller. For this low amount of LEDs the controller can provide enough power so I directly connected everything to the controller pins. I am using a micro USB cable connected to the NodeMCU to program and power everything. I only wish I had been able to further sand the acrylic parts to better diffuse the light and make the whole inside not round but the same form as the outside. This would have allowed the light to spread a little more evenly. While you might be able to spot it in some of the pictures in reality it is nearly invisible.

Very sleek, stylish, and easy to fit. Solid materials with multifunction compatibility, If you’re looking for just headphone purposes and a better quality aluminum headphone stand, then you may like this Satechi Aluminum stand. We highly recommend you get any of them if you plan on buying them for your desk. Part of the vision for this project was adding colored LED effect lighting. Not because I need it but because it looks awesome! I decided to try out SK6812LED strips. They are individually controllable LEDs similar to famous WS2812B “Neopixels” but they have a separate white channel for more accurate white tones (RGBW). I am very glad I built this. It took a lot more time than I expected (around 20 hours overall I think) but it is definitely worth it. With the LEDs turned off the headphone holder looks nice and blends in with the wall but with the LEDs turned on it becomes a center of attention.The magnets are easily strong enough to hold everything together, they are invisible from the outside and I can access the electronics inside at any time. Ah yes and wall-mounting is easy: I drilled two more holes in the last layer and screwed it into the wall. Then it is simply a matter of plugin in the rest of the holder. The lighting I was looking to not only use different colors but also play around with animations. When I started this project I first wrote my own code based on the Adafruit Neopixel library and MQTT to control the headphone holder lights. I never had the time to properly develop it past the very initial versions though. Software and smart home integration
