Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Have almost the same box. Tanner or sidewalk can't recall... Mine was already punched for some sort of 5 lightbulb demo. Figured with retro lamps I could maybe demo relay logic. Already upgraded front panel switches from SPST to SPDT. 2bits + 2bits + carry. Other controls still need to be drilled. Relay rail just sitting for the photo, not yet attached.
Those relays got LEDs in em' already, but only work in one direction. XOR across a relay coil is bidirectional. Should ditch those coil MOVs for diode bridges instead. Edited 2022-04-17 15:03 by KD5ZXG
