Hello there, this is my first post on the forum. I've done as much reading as I can, but I can't seem to figure out my problem. I'm trying to activate a pull solenoid for 1 second, after a delayed timed reaction. I'm looking for the timer to be adjustable, in the range of 5 minutes (potentiometer?). While inactive, the solenoid would be in the push position, and after pressing a button, and then after the delay, I need to trigger the solenoid to retract for 1 second, then kill power. This needs to be a one time use, with no cycles. I was looking into 555 timers in the setup for the ham radio LED reminder, but I am coming to find out that it might not be able to handle the load carried to actuate the solenoid. Any suggestions? It needs to be as cheap as possible and battery operated, as I am not the wealthiest person around!
Any suggestions that may help me research in the right direction, would be greatly appreciated! Thank you so much.
