I have several air powered props that I built over the years.
This year I want to add sound to some of them when they activate. I want to use an amplified sound recorder, which is simple enough. Can anyone tell me a good way to trigger the sound recorder when the prop is activated.
I am triggering the solenoids of the air props with motion (Combo Flex ECT) detectors from Haunt Master Products. These work great. I want to be able to trigger a sound recorder at the same time. Can anyone help?
