I've recently been deep diving into the YouTube channel Techmoan. Host Mat unearths and reviews an absolutely ridiculous amount of music tech gear. From the more recent RokBlok player to Baby Driver's Tape Scratching Machine to the forgotten format of Phillips DCC. It's a massive repository but there doesn't seem to be a bad entry point. Here's a few that I've enjoyed lately:

• VHD: Movies on Vinyl - who needs lasers for video when you've got a needle?
• The Floppy Disk Boombox - MIDI for the street
• VinylDisc - an LP and a CD all in one from 2007 and died before it ever made it out of the gate.

It's nerdy but a highly entertaining indulgence.
