The full story
After a few years of on-and-off work, a maker's persistence-of-vision bike light can play video: 168 LEDs on a spinning wheel draw the picture, and frames are streamed over Wi-Fi at about 8 to 9 frames a second. He designed and built the PCB himself and wrote the Wi-Fi streaming code with help from Claude, the part he had been dreading.
It still needs better speed estimation to stop the picture stuttering.
Parts and cost
- Custom PCB with 168 LEDs, designed by the maker
- Wi-Fi microcontroller for streaming frames
