Hello
I would like to know if cadnium sulfide photocell hookup to a transistor have enough voltage or current to turn a transistor on to cause a relay coil to pull the contract close , as long as the cadnium sulfide photocell have light shine on the photocell, without using any outside battery power to transistor or the relay.
If can be done ,can you tell me where can I find a circuit like that.
