LED matrix cylinder

This is more a test project if a WS2812 based matrix also looks nice in a cylindric shape. I am thinking about a much larger version, but first I want to learn on this small one. I am using the rpi_ws2812 python lib to directly drive the LEDs from the Pi.

Just the test code from the video ;-)

As in my previous LED matrix project, I am using a pygame based simulator for testing the python code on the PC. Code will follow soon on Github.

Here are some more pictures from the LED assembling:
Matrix body

Matrix was designed with Fusion360 and cutted with a laser cutter out of thin cardboard.

It is splitted into two parts to simplify LED assembling and cabeling.
Height is 18 cm, diameter is 20 cm

i really love this, i'm going to use your case design, but using nodeMCU instead of Rapsberry Pi

Is it ok if i use your case design and post in public?

Are you sure? yes | no

That's why we are here ;-) There is also an instructable to this project:

https://www.instructables.com/id/LED-Matrix-Cylinder/

So if you use the design, please insert a clear reference/link to this project and insert links to the used files (e.g. case design) instead of just copying them to your project.

Are you sure? yes | no

This is really cool - I'd love to have a go building one as well...

Will you be including a wiring diagram?

Have you the cutting file for the frame?

I'm kinda new to this so please forgive me if I break some social norm by asking.

Thank you

Are you sure? yes | no

No problem, that's why we are here ;-)
I have written an instructable with cutting file and schematic:

This is one of the most beautiful projects I have ever seen done with a Pi.
