Testing

Testing out the LUMINA. Had to change one resistor value, but it's working as expected. I just soldered in whatever LEDs I had lying around for testing. Normally you'd fit the board inside a case and route the LEDs to wherever they need to be.

First LED is always on. Second is on when it's below threshold. Third is on when it's above threshold, and fourth pulses when it's above threshold and is solid otherwise.

As you can see, it's not exact. There's some slop in the thresholds because it's basically working as a series of analog amplifiers and there's going to be some variation and fuzziness as MOSFETS reach their threshold voltage. But in practice the current doesn't really really sit in that indefinite range very much.
