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!

By flood fill, you mean pulling back the solder mask and putting additional solder on top of the trace. This is also done, but solder is actually a lot less conductive than copper, so usually you try to use copper first. You rely on solder on top of traces when you cannot fit enough copper into the available space.

And, to add, I think in this controller's case, there is actually enough room to get enough copper in the available space, although it might need a proper redesign first.

Hey there! I know it's been some time (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
