Has anyone on here managed to upgrade their Spatcave, or Chef's kitchen motion tracker with sound effects? I'm still brainstorming about how I can install two layers of sound into mine. I would like to have the 1st one be of a constant pulsating tick, while the 2nd sound be the beeping set off by a motion sensor activated by a device of some type. The device can be placed near a vendor's alien related prop with permission from the vendor of course, and on second pass through the convention, a sweep can be conducted during which the tracker is set off.
