iRacing Plugin for Prismatik

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.

Color Matching with NeoPixels

I keep getting distracted by other projects and ideas, but I wanted to post a brief update on the footwell NeoPixels project. I’ve been working on the data structures and color patterns, but today I wanted to cover something simpler. For the time being I’m not planning on changing the color of the tC’s interior lighting, which is a nice burnt orange. I’ve toyed back and forth with the idea of replacing the tC’s cubby light and adding a few lights to the cupholders, which on a default setting should match the rest of the lighting. This gives us today’s…

FastLED vs Adafruit_NeoPixel for RGBW LEDs

Multicolor LED strips generally come in two flavors – solid color and addressable.  Solid color strips, as the name implies, have all of their LEDs display the same color.  Addressable strips on the other hand allow you to control the color value of every individual LED in the strip.  The most popular individually-addressable LEDs on the market at the moment are Adafruit Industries’ NeoPixels, based on the WS2182 chipset.  They come in a variety of physical packages including strips, rings, and matrices.

NeoPixel Prototyping Board

While the final version of the footwell NeoPixel project calls for a long strip of ~60 pixels, most of my time is going to be split between programming at my desk and testing the pixels’ response to telemetry from the car.  I didn’t want to have to wrangle a large strip every time I wanted to test an idea, and I figured most of the patterns for the 60 pixel strip could be replicated on a shorter one. My solution is this small prototyping board.  It’s a 3D printed part with mounts for an Arduino Uno, a small breadboard, and a NeoPixel…

Footwell NeoPixels: The Plan

This is going to be the first big project documented from start to finish on this blog. I recently had the the idea to put some lights in the footwells of my car, a 2008 Scion tC.  There are a variety of kits available online that use standard multicolor LED strips, but I was never fond of the options available. For one, the control interfaces are clunky and scream ‘mod’.  Most of them use thin remotes, though a few have small control boxes attached directly to the LEDs.  I wanted a control switch that integrated into the car’s switch panel…
