Vacuum-tube computing circuits built at safe low voltages, plus a growing vintage museum.
Old-school technology with vacuum tubes at the center: computing circuits inspired by the legendary machines, built with deliberately low plate voltages so they’re safe and followable at home. Recent: the PDP-11 gaining dual 8-inch floppy drives, a TM990 running Conway’s Game of Life, a first journey into high vacuum, and a Tony Sale Award win for the Colossus-adjacent work. 145K subscribers, weekly uploads.
