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 christmas 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 counts thogh ;)

Anyways, this is what i came up with:

It's 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 between with a button on the bottom side of the case. A second button changes the brightness. That's all for the functionality at the moment. BUT when there is the inevitable break between meals on christmas i plan to create 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 free to make your own or suggest some changes ;)

1. at least that is what i thought ;) ... My gf isn't 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); stl files are available also ↩︎
