I built the Promethium and it works fine, but the LED doesn't light up.
It switches on and off as expected, the continuity seems good on all of the off-board wiring, and the LED is getting 9V according to the multimeter. I tested a few different LEDs to see if I had a bad one, including different orientations. Nothing. Any ideas? I'm stumped because it's getting power.
