Using WS2811 LED chains

Update: I also tested Spectre's new Software to control LED Matrix display from PC, Android or Raspberry ->

I discreetly made public the repo of LEDs master Go test it, there are versions for all platforms. I know a lot of people really want to be able to control LED masks and costumes, wirelessly. feel free to give me lots of feedbackhttps://t.co/duSrRs1rTl#LEDs #lua #love2d #dmx pic.twitter.com/7pO2k65nW8

Code for the ESP32: https://github.com/spectrenoir06/OctoWifi-LEDs-Controller

Code for Win / Android / Debian: https://github.com/spectrenoir06/LED_master/releases/tag/V0.4

I added screenshots with the parameter changed for this LED wall to the project

Printable version instead of metal hole pinching and welding.

All parts printable without supports, size of each part smaller than 20 x 20cm

4x4 table tennis ball pixels per print part, so the final size is modular.

In this assembly 33 x 18 pixels are used for a roughly 16:9 screen in 1,5m x 0,75m

Framework with caprails for better stability.

Integrated ESP32 with Webcam in the middle for direct stream or any other arduino controller

I included also the Step-Files of each part for easier modification and also a Step-Assembly with all electronic parts and an according PDF-drawing

I printed the parts in PLA with 0,3mm height for shorter print time.

Roughly 2-3h print time per part

I used following parts in this build:

A small 5V PIR sensor and a relais to switch on the main power supply only if somebody is in front of the video wall.

Have Fun!
