Have you ever watched an air guitar competition? Watching strangers enthusiastically do something in public that we generally only do in private is a wonderfully intimate, exuberant experience. But does an air whistle outdo an air guitar? You be the judge. Here’s more from o.c.2799 via Insstructables:
The slide whistle is a musical instrument often used for comedic effect due to its silly sound. In this instructable, we teach you how to make an air slide whistle! What is an air slide whistle? It follows the same idea as air guitar where you mimic the movement of playing a guitar without actually playing a real guitar. In our case, we created a device that functions similarly to the slide whistle, except a distance sensor replaces the rod and a push button replaces the user having to blow into the whistle. The reading on the distance sensor changes the pitch of the noise and the push button activates it. The LED light are just for show. What makes our air slide whistle “universal” is that you can upload different sounds to it besides a whistle noise (i.e. wookie noise, trombone, didgeridoo, or any other sound bit you want)! We made this project in collaboration with the Femineers of Fremont Academy for our Electronics class in Pomona College.
