Ok, I know everyone wants to build from scratch, but theres a lot of really nice stuff coming out each year from the mass produced guys, but their triggering systems suck. Props like "Spasm, Hex, the moaning mummy guy at hope depot" most commonly use a photovoltic cell I believe to notice changes in light. They are generally little black tubes leading into their chests. My problem with these things is that they don't seem to respond to infra red, and are virtually useless in the low light conditions of my haunt. A work around I have used before is to have one of my triggers trigger a light bright enough to activate their triggers but because I cannot always control the movement of the tots this doesn't always work. Further more some props like "zombie chin up" and "chest ripper" have audio sensors that trigger from load noises. The only thing I have done for them is place them on boards that transfers the sound of the steps to the prop "ussually" triggering it.
Now does anyone know can I simply short the leads going to the light sensor or sound sensor together to keep the prop always active, so that I can activate the prop using it's power cord. If not, how can I bypass the light or sound sensor on these mass produced props (ussually two lead sensors)?
