To suit my needs and my bits box I took the circuit below meant fo 6 V olts and used it in a 24 Volts system with a 24Volt relay and bumped the Variable resistor to 200K.
It works fine but of course the tranny gets pretty hot . Too hot to touch
I used a 2n2222A tranny
Can anyone suggest a modification to reduce the heat through the tranny as it will be on all night and I fear it will blow pretty quickly atm.?
Another issue with the design is it is a shadow detector rather than dark detector . It seems like it maybe needs a little more resistance , maybe a 500K pot I might try
Can anyone throw it in a simulation please I want it to just turn on at dark and stay on with minimum current use
