​Power issues solution and new system design

A project log for Unconventional Instrument Ochestra

using hardware like floppy drives and 3D printers together to play any MIDI file

I've finally decided to solve all my power supply problems. Currently, I have seperate power supplies for my 3D printer, my Raspberry Pi, my thermal printer, my various miscellaneous projects and now I need a power supply for my floppy drives. I plan to fix all this with one big old ATX power supply.

It's going to be hooked up to my all purpose Raspberry Pi server, which controls the standby/active state of the power supply with both a physical button and software commands. This power supply will also power my 3D printer, and my floppy and disk drives. I'm sure it won't be a problem, seeing as floppy drives and HDDs are designed to be powered by these things.

I also plan to finally integrate something I've wanted to do for a while now: put the Pi in charge of the orchestra. I'm going to try and make a little server program that my GUI client would connect to, and send over a processed MIDI file for playing, since my Pi is also an Octoprint server. That way, I won't need to keep changing what my 3D printer is plugged into.

I've updated the main page to include a "System Design" reflecting how this would all work. I'll also include it here because those thumbnails are weird:
