Drum light trigger that uses leds, a NE555 timer and a piezo transducer

This circuit is a Drum Light Trigger.



It uses a piezo transducer that reacts to drum vibration, and a NE555 timer to setup the light time.
There are two trimmer pot, one to setup the sensibility of the vibration, the other to set how long the LED light will be active.
This design is a small makeover of a circuit i've printed from an online image, unfortunately i can not recover the original author.





About the video: The piezo is attached to kick drumhead, and the led strip is inside the kick. I'm not a drummer, so there may be many imperfections in the way i play, but it's just a video to show you how this drum trigger wors. I've just add some synthesizers and guitars to make it sounds better. For those how are interested in, it is recorded using one wm-61a phantom powered condenser mic, and then processed a little using the Reaper digital audio workstation software.
