Calculating Adalight Framerate Limits

I recently posted a few ideas about how to improve the framerate of an ambilight driven using the Adalight protocol. Before trying to implement some of those options, I thought it would be worthwhile to actually calculate the theoretical framerate limitations.

Investigating How To Improve Adalight Framerates

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 Amblight with WS2812Bs: Conclusion

We’re done! The ambilight is in place behind my monitor and has been running great. To finish up, I wanted to reflect a bit on what I learned and talk about where to go from here.

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 Read more

DIY Ambilight with WS2812B LEDs

Overview The goal of this project is to build a dynamic backlight, also known as an ‘ambilight’, for my PC monitor. An ambilight changes colors based on the content onscreen, extending your monitor to the wall behind it. By reducing the contrast between the monitor and the background it can Read more

DIY Ambilight: Making a Custom PCB and Case

So far the hardware side of the Adalight setup has been a nest of wires on my desk, with the Arduino on a breadboard and the power running through a terminal block. Now it’s time to wrap up this project by getting everything off of the breadboard and onto a dedicated PCB in its own custom case!
