Making a color temperature tunable, high-brightness LED lamp #ESP32
Aylo decided to make a color temperature tunable, high-cri LED lamp:
I wanted it to be able to control the color temperature and brightness, and I wanted it to be really bright. I experimented with a single strip, and detailed how the control board would work. If you want to try to build your own, the code/boards are here.
It packs an ESP32-C3, because I had one on hand, and because connectivity is important for this project. In addition to manual over-the-air control, I want to be able to put the lamp onto a simulated daytime color temperature loop- a real-life version of f.lux, which turns up the warm temperature light on your display as the day progresses. I also would like to add a way to sync it to some kind of live color temperature data.
This lamp, despite not achieving one of my crazy tensegrity ideas, fancy woodworking concepts, or brass-pipe dreams, does use one of my favorite tricks: using orings as precision rubber bands. The LED channels are very thin, and therefore fairly hard to attach to with screws. They are meant to be mounted with supplied clips, but I didn’t feel great with those overhead, since they are not closed on the bottom.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
