Update 2021: After pausing the project for quite a while, I will take the "Rethink Displays" contest as a hint to do the next step planning and building the large version with at least 1600 LEDs.

Planned features:
- Minimum 80x20 pixels
- multiplayer gaming (Tetris, Snake, etc.)
- full cylindric animations
- modular design for easy transport and maintenance
- full open-source hard and software

Plan is to bring it to future post-pandemic Maker Faires.

It will include all the learnings form this project hanging on my wall since several years now:
https://hackaday.io/project/11064-raspberry-pi-retro-gaming-led-display

Older project posts relate to a test project for a 20x5 pixel WS2812 based matrix in a cylindric shape. I was already thinking about a much larger version, but first I wanted to learn on the small one.

First test after full assembling:

  • Full matrix design

    Just to get a first impression about the matrix, 90cm diameter, 70 cm height:

  • Large matrix design

    makeTVee • 05/29/2021 at 09:34 • 0 comments

    The grid for the new large cylindric matrix (right now 84x20 LEDs) is designed in Fusion360 as a full parametric design, so by changing the number of LEDs for x and y and the material thickness, Fusion automatically redraws the matrix segment. I will use 30 LED/m stripes, so the diameter is close to 1 meter.

    To make assembly and transport easier, the design is made for a quarter of the cylinder ,which then later will be combined with 3 other quarters to the full cylinder. Next steps in the design process are:

    • mounting of the LED stripes
    • connection of the quarters
    • cable guiding

    Also started to model the matrix in P5.js to do some animation simulation.

    Finally added the source code to my GitHub.

    Just the test code from the video ;-)

  • Software simulator

    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.

  • LED assembling

    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

Hi you told me on youtube to contact you here for a plan and instruction for a big matrix cylinder.

  Are you sure? yes | no

makeTVee wrote 05/24/2021 at 14:48 • point

oh, missed this, added you to the project, so let's discuss via dm

  Are you sure? yes | no

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

makeTVee wrote 01/22/2020 at 07:53 • point

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

OK

HI

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

makeTVee wrote 03/16/2019 at 13:14 • point

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

many thanks. 

This is now in the list. 👍👍👍

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

  Are you sure? yes | no

What have you used as a light diffuser? Paper ?

  Are you sure? yes | no
