I love how you say this is really simple... and then proceed to start speaking total gibberish (electronic/mechanical jargon) as far as I'm concerned.
I wish I knew how to do this stuff like all of you mechanical wizards!
Great prop - love the effects! (and I have two of those haunted hedges and am using one for a low tech monster in a box! )
Ok so for anyone looking to add the haunted hedge to this here is the wiring I used this relay is the button on the bottom of the controller right next to the one currently being used for the actuator. this will put the actuator on one button and the hedge on the one next to it!
