I’ve been trying to teach myself a little Python, and here’s what I came up with for my first small project. Using their respective APIs, I’ve built a plugin for the Prismatik ambilight software that maps live data from the iRacing simulator. A video demonstrates the end result far better than I can explain it: The plugin itself is open source and hosted on GitHub. Click here to download the latest version.
Now that I’ve calculated the theoretical framerate limits, it’s time to measure the actual framerates my Adalight device is putting out. Using a logic analyzer and an Arduino Nano, I’m going to measure the framerate at varying Prismatik “Grab Intervals” and baud rates, and compare those numbers to what my calculations predict will happen.
Since I’m experimenting with increasing Adalight framerate, the first step was to try driving the Arduino Nano with a faster serial baud rate. Unfortunately, Prismatik only supports three baud rates: 9600, 57600, and 115200. But after talking with Patrick Siegler, he pointed out a way to use your own custom baud rate for Adalight or Ardulight devices.
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 also help with eye strain. There are some commercial versions of this product, but I wanted to see if I could make one myself with WS2812B addressable LEDs (also known as NeoPixels) and an Arduino. This was a fun project and I’m really happy with the end result. If you’d…
