Building a animated RGB-LED Thingy 2019-12-01T16:53:22+01:00 false quick and dirty diy-christmas present(s)
/static/img/led-cricle-rainbow.png

This year for chrismas i set myself the challange to not buy anything new to give away as presents. Better for the enviroment and forces me to get creative1 with the stuff i already have lying around. I ended up desgning something with my 3D-Printer and the fillament techincaly did lie around... not sure if that count tho ;)

Anyways this is what i came up with:

rainbow anim

Its a 3D-Printed enclosure with some paper glued to as a diffuser for LED lights. The Brains is an ESP32 running micropython (which i praised in my last [post]({{< ref "/posts/dabbling-micropython.md" >}})). Right now it just plays 2 "animations" which you can switch with a button on the bottom side of the case. A secound button changes the brightness. Thats all for the functionality at the moment. BUT when there is the inevitable beak between meals on christmas i plan to build some more nice animations and try to expose a REST-Interface to be able to change animation and brighntess over the network.

I put the design files2, the code and some basic instructions on github. So feel to make your own ;)

  1. at least that is what i thought ;) ... My GF isnt realy impressed with RGB-LEDs anymore ^^ ↩︎

  2. all created with FreeCAD <3 (im still learning that software so the design is probably realy badly made) ↩︎
