Hi I am wanting to make a can crusher. I want to use a 12v dc actuator. I want it to simply crush the can and automatically retract back and keep going until you push a stop button. I was thinking maybe some photo eyes and latching relays or even a timer. But I need to know how you would wire this up so it will work right. And I need to convert the actuator 12v to 120v . Any suggestions about how to go about hooking this up. Maybe a step by step
