First up, out with the ironing board (soldering iron is an iron, right?). The dotstar LEDs run at 5v and the Pi's GPIO outputs at 3.3v, so we need a level shifter/bus buffer to bump the volts up a bit.
OK, bit of swearing and fixing some bad solder joints later and the leds are working. Time to make something to mount them in.
The gap between the base and the front is deliberate, however, to provide a little bit of air circulation otherwise the box would be pretty well sealed.
Bits and pieces installed, time to glue on the perspex. A nice layer of epoxy and 24 hours under clamps. Need more clamps.
This was a really fun job. Gluing the leds to the inside edge of the perspex. Very satisfying.
I also had to cut down the switches so they'll fit the lovely machined solid aluminium knobs I had to go on there.
knobfeel, nice and heavy but still good and positive. Very satisfying. Each knob triggers a playlist in Kodi, and if you turn on more than one knob, it creates a playlist made of a mixture of all active playlists. I've put my code for controlling dotstar leds with a raspberry pi on another post.
View from the top. That tulip is so pretty.
Here are the lights in action. No audio because every time I post audio to YouTube I get told off for copyright infringement even when I'm super careful to find copyright-free music tracks. Just imagine some music you like is playing. Click through to YouTube for lovely HDness.
Obligatory link to my store, where you can't buy things like this but you can buy other lovely shiny stuff.
