[simpits-tech] controling a 28v circuit with a 5v

[David C. Allen]

I used 5v low current relays to isolate and control the 28volt lamps.

I built this little circuit board to control the landing gear lamps 
for a friends sim.

It uses relays I purchased on ebay and is controlled by a Go-Flight 
Landing Gear module. I think I paid $5.00USD for 20 relays.
