More fun and games with high voltage Hey everyone! I know it's been a while since the last video, but things have been crazy busy with shipping off the ESP32 Rainbows. Lately, I've been diving into the world of high voltage again. My last endeavor with a high voltage board led to some gnarly waveforms and flickering LEDs, so I tested with beefy resistors but wasn't thrilled with the results. Fortunately, I've found some nixie tube driver boards that work wonders with LEDs, providing smooth output with little ripple. Still, playing with the old boards has its thrill—hello, 787 volts and some wild sparks! Stay tuned for... 14 June 2025
Self Organising WS2811 LEDs I've successfully used addressable WS2811 LED strings and an ESP-CAM board to create an adjustable lighting system. The best part is that the image processing code can be duplicated in JavaScript which allows you to use a plain dev board to drive the LEDs instead of needing a camera on your ESP32 board. If you want to replicate this project, you'll need your own ESP32 dev board and some addressable LEDs. After figuring out the location of each LED in 2D space, it's easy to map from each LED's x and y location onto a pattern you want to show... 05 June 2020
