I tried to wir up the gear tooth sensor last year, and it coused the camera to freak out, something about it being a costant hardware interrupt or something. How would you make it so the signal doesn't kill the camera?

That sensors doesn't need to be on an interrupt, it can be polled. Just connect it to a digital input then every loop just have an if() statement check it, if the sensor is on, turn off the compressor. I think the default code has stuff for this towards the end for digital input 18 and relay 1, but I'm not sure.
