This thread was inspired by Dave's "New pneumatic prop" post and his use of a fancy prop controler. BTW - great job on that Dave! I haven't made the leap yet to high tech and Ohms law states that, "Russell will NEVER understand electronics." My props rarely make it thru mutiple seasons, often banished to the attic or scavaged for parts so I made up some generic controlers. Power, air, and audio input. Two or more air valves (I'm prefer Mac valves) to make a prop go up/down or in/out. Audio output via an automotive relay and power output for eyes or lighting all controled by a remote receiver/transmitter. Made to fit in a shoe box for ease of storage. If you are a patient Ebayer the parts should cost well under $100. Anybody else using "low tech" controlers?
