DIY Media Key Footswitch for PC

I spend a fair amount of time down in my garage working on things, and while I’m doing that I like to listen to music. I set up an old computer that runs Spotify and sends the audio to a pair of bookshelf speakers. This setup works great, but it requires using a keyboard and mouse to control it. Often times my hands will be gloved and coated with something nasty: grease, epoxy resin, paint, you name it. So I wanted to come up with some sort of method to control my music when my hands were unavailable.

This is what I came up with: a two button footswitch controller that connects with USB and handles play / pause, next track, previous track, and volume.

How to Control the LEDs on a Novation Launchkey Mini II

I picked up a Novation Launchkey Mini II controller last year when I was working with those musical floppy drives, and recently I fell down the rabbit hole of Launchpad LED performance videos. That got me thinking: is it possible to control the LEDs on a Launchkey Mini like you can on a Launchpad?

There’s surprisingly little information about this. Novation’s user guide for the Launchkey Mini has no mention of how to control the LEDs. There is some information available in a “programmer’s reference” manual for the Launchkey II (not the “Mini” version), but sadly the LED components don’t function the same way.

It required a bit of reverse engineering and the result isn’t quite as pretty, but I’ve figured out how to do it.
