Solid State Rallye Gauge Instrument Voltage Regulators (IVR)

NOW the level-up of the workstation in the sweatshop is complete with proper lighting and accoutrements. Yes, I am still trying to hand-off the lion's share of this project to others, but since I'm so much better equipped now, it seems a shame to not build more of my own.
PM me if you need one or a few.
