This is an attempt to get a wind chime to nicely glow when it chimes. This project has been shelved. In order to do this properly everything needs to be miniaturized. eg. wiring interwoved with the support strings, flexible circuit boards, custom printed waterproof housing etc. Up until that point it just won't swing properly and do its job as a wind chime.
- the wind chime center weight swings and knocks the tubes
- sensors pick up knocks and trigger the led's
- led's quick on, then fade off
- led's brightness determined by knock value
- LED's are mounted in the bottom of the tubes (i drilled a hole through from the top)
- knocks on the tubes are picked up by
- (a) piezo sensors mounted on the tubes,
- (b) tilt-switches mounted on the tubes,
- (c) corresponding copper strips on both the center weight and the tubes (connecting to make circuit),
- (d) piezo strip mounted around the center weight (triggered by collision with tubes),
- (e) accelerometer chips mounted on the tubes.
- Sensors tested
- copper strips (connecting with center weight)
- Sensors NOT tested (more expensive)
- piezo strip with weight,
- accelerometer chip
Enjoy this project?
