Anyone have suggestions for YouTube channels where people are creating cool new stuff for old computers?

With notable exceptions, I'm less into "here's an $OldMachine, how cool!" and want more "here's a new thing I made for $OldMachine that makes it really useful or usable today."

EDIT: By the way, this can be hardware or software. New storage devices, expansion cards, network adapters and sound cards are just as interesting to me as new SDKs, new compilers that target old platforms, weird ports, and ancient driver mods.

Open Firmware NetBoot with a third-party Ethernet card

Have you ever wondered how an (old) Mac boots? Or have you wondered about Open Firmware, similar in purpose to the PC BIOS (though arguably far more elegant and refined)? Have you ever slogged through installing device drivers after adding hardware to your computer, wishing there was an easier way? In this post we’ll dive deep on these things and more as we explore the process of building an Open Firmware driver enabling a PowerPC Mac to boot over the network using a non-Apple network card powered by the RTL8139 chip.
