I have 8 heath zenith carriage lamps with dual bright control circuitry. They detect light and motion. Does anyone have schematic for the HZ-4192? It looks very similar the 4152, however the 4192 has a potentiometer. If nobody has anything I will proceed with my plan of creating a schematic myself. And will probably make a boat load of errors along the way.

 

I would not think those could be very complex circuitry to reverse-engineer?

Can you come up with a Heathkit Model Number? I have their complete set of manuals on a CD. Searching it for lamp or carriage yields nothing...

I'm not sure it will save you any time but there are automated tools for deriving a schematic from good photos of the PCB. I'm guessing the PCB for this device is single layer, and therefore the tool may have a decent chance.

I've never actually used one of these tools and therefore can't recommend one in particular. Could sure be handy if it works.

I saw KiCad listed in other places.
