I’ve been wanting something better than a long string to release my spring loaded clay target thrower. I will have 12 Volts DC at my truck where I shoot. My hillbilly self initially thought about a fast idle solenoid for a carburetor and air conditioning. I believe those automatically retract. I’d still have a length of speaker wire with a momentary trigger switch... Not much improvement over a long string.
What would it take to get into this century? Door lock solenoid and a key fob? Those fobs are probably expensive and overkill for doing one function. I’d like to go wireless! Anybody have some better ideas?
