The original Piezoelectric micro air Blower had a good run on Tindie, but now microwavemont is back with version 2.0. The new version has a built-in LDO for more stability in the supply voltage variation.
Since this Piezoelectric Micro Air Blower V2.0 doesn’t have a motor or fan, it instead uses an ultrasonic 26kHz signal and acts as a tiny air pump. Some use cases include water aeration, kinetic actuation, making small items hover, or even using it as a notification for the hearing-impaired (by using air flow).
The lightweight design and small form factor makes it easy to implement into your projects. There’s also no need for a high voltage source or an oscillator circuit. You only need to provide a 3.4V-5V power supply.
