A piezo buzzer is used to detect the vibrations inside the drum, each hit triggering a different color combination. The LEDs fade to off after each impact as if dying along with the sound ...

[Dan] achieves that by using a normal piezo disk. These disks are used as speakers and buzzers in everything from smoke detectors to greeting cards, so they’re common and cheap. [Dan] cut his ...

Same Sky has added to its portfolio of disc-shaped piezoelectric elements, with devices from 12 to 35mm in diameter and down ...

In an exciting breakthrough, researchers have developed a high-order finite element model to analyze the hygrothermal static ...
