Thread: DIY Steel Plate Impact Detection

Yup, just a strap folded to have a hook at the top that fits neatly over the plate. Possibly doesn't need to hang too far down the back either, and would probably have plenty of pressure to keep the sensor firmly on the back of the plate so no need for magnets. Like those hooks they hang over wardrobe doors. And would be transferable to any plate. I think your units stand much greater chance of being damaged when travelling and setting up if permanently attached to the gongs, hung as a separate unit would negate all that worry.
