I don't use LEDs so I'm not sure what I'm looking at. Could you explain the problem your addressing? Does the board makes LEDs look more like incandescents?

Quoted from herg:Yeah, making LEDs look more like incandescent bulbs is the idea.
Due the the instant on/off nature of LEDs, many people see flicker or a strobe effect when the lamp matrix is scanned at 62 Hz. This PCB monitors the outputs from the lamp driver, then re-drives at 250 Hz. That's the flicker part.
Dimming is controlled by varying the lamp row active time based on the configuration from the PC. That's the dimming part.
The PCB then ramps up/down through the configured brightness values in order to make the LEDs fade on/off like incandescent bulbs.
Sounds very promising. I've always had an issue with LEDs when playing others pins. I like the idea of the lower power pull and hear of LEDs but the look has always steered me away.
Would love to try it in my AFM.
