I got all the parts from Ebay. This e cig has to have the button pushed to make the smole. To solve that problem I purshaed a small soleniod. The recoil activate a switch. When closed the solenoid is activated and pushes the button for the e cig and it operates another switch then energizes the fan. You have to either find the perfect spring to return it to ready or install a simple 5555 delay timeand reversing switch like in my operating tank commander.
Hey does anyone have a spare Sherman?
