Controlling Musical Floppy Drives Directly via MIDI

One of my first thoughts on how to improve Moppy was to drive it directly via MIDI. At the moment, the format of serial messages sent to the drive controller is proprietary and requires using the “MoppyDesk” application on your PC to convert MIDI notes into playable pins and wave periods.

What if we can skip the PC altogether and simply plug a MIDI cable into the floppy drive controller? The goal of this experiment is just to see if this is feasible.


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 problem: how do we match the NeoPixel’s color with the other LEDs?


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.
