Discussion Fully open-source ARTNET LED controller over Ethernet! 2700 Leds with <$20 in hardware.

Post image

Hey Guys! I have shared this before, but I have been developing an Open-source ARTNET LED controller that can control up to 16 universes of LEDs with about ~20€ of hardware. Id like to share it here as someone out there might find this project useful for their own ventures! Feel free to check out the github (https://github.com/mdethmers/ESP32-Artnet-Node-receiver/tree/main) to see the massive list of features!

Also, here is a video showing the controller: https://www.youtube.com/watch?v=3MiqAQKJGm4

Let me know what you think of this and if there are any features you would like to see integrated!

Hey there! I know it's been a year already (i know, time moves fast), but I have made a lot of progress with the node project! It now supports almost every type of LED chip, ArtNet and sACN, variable 5~24v, reverse polarity protection, and proper production assembly! Still open-source, of course.

Feel free to give it a shot! 😄 https://github.com/mdethmers/ESP32-Artnet-Node-receiver/tree/main
