I want to use fog in a couple of my new props, including my electric chair, but I want to use it sort of "on demand". In other words, the electric chair will be activated using a prop cotroller/timer. So when the prop is activated I want the fogger to activate but then stop when the prop stops. Anybody know how to do this or have a "how to" tutorial? Most fog machines have cotrollers with the simple "Manual" button and the other timers have the "timed" functions, but I only want it to shoot fog when the prop is activated. Thanks!
