Using a 5.25″ Floppy as a MIDI instrument

A friend and I recently uncovered a 1992-ish PC, boasting 4MB of RAM, a nearly 500MB hard disk (aftermarket, we believe), and a dual 5.25/3.5″ floppy drive! Stymied by the lack of a compatible mouse (as this was well before the era of USB devices), we could boot from it, but not operate it. So after wondering for a bit what we could possibly do with it, we decided to take out the floppy and try to adapt it for a modern computer.

Building a MIDI Pedalboard

Fact: Weber Music Hall has a MIDI pedalboard. If memory serves it might be the Roland PK-6. Or maybe not.

Fact: It’s awesome.

Fact: I want one.

Fact: I don’t have the many many hundreds of dollars it would cost to spend on things like MIDI pedalboards. However, I do have several junked organs’ worth of components and a seeming excess of free time.

Therefore: A midi pedalboard! Building it was surprisingly simple and straightforward (that is, after a two hour diversion of several circuit rebuilds necessitated by the assumption that the circuit was not being built around a faulty shift register. Spoiler alert: it was!).

Introduction

Web-controlled lights: Who doesn’t need ’em? I’d had my eye on something of the sort when I made the decision that none of the prebuilts available met my needs…I was going to have to build my own.

Specifically, I wanted a couple of particularly hard-to-find features:

  • I wanted these to be controllable via a well-documented and easy-to-use API (preferably something fairly REST-compliant).
  • I wanted something reasonably unlikely to die when I needed it to work (and I wanted to be able to fix it when it inevitably did).
  • I wanted to be able to securely share access with a handful of people, but not leave it wide-open for the internet to abuse.
  • I wanted to control not only the standard switched 120v overhead light but also some custom LED RGB lighting.
