Improving Adalight Framerate

As cool as I think ambilights are, using Adalight with my DIY setup has one major limitation: framerate. Video technology works on a principle caused persistence of vision, which means that our brains still “see” an image briefly after it’s taken away. If you replace the images quickly enough, our brains interpolate the differences between them and we get an illusion of motion.

DIY Ambilight: Videos and Gifs

Project complete! The LEDs are in place, the code is done, the PCB is built, and everything is installed and running. So what is there left to do? Shoot some videos of everything in action! In all of these videos, the ambilight is generating colors in real time based on the monitor’s image. The monitor image is as-filmed and is not superimposed.

Adalight with FastLED

I’ve previously mentioned that I was initially using this code by James Bruce to drive the ambilight. While I was waiting for the circuit board components to arrive, I thought I would take some time to expand on his work, fix some bugs, and add a few features I thought were missing. After a few recent tweaks it’s now ready for distribution. Presenting: Adalight-FastLED! I’ve reworked the Adalight code to provide user-friendly options that allow you to easily customize it for your setup. I also added a brightness limiter and a calibration mode, which sets all LEDs to the same…
