This auto-flute does it with steam. Well, electricity gets its piece of the action too as the tone holes are opened and closed using a set of solenoids.
We’re at a loss on how the sound is actually produced. We would think that a penny whistle has been used here, except if that were the case the solenoid nearest the kettle would have no use. Then again, after watching the demo after the break we’re not sure that it does have much of an effect. It may be meant to stop the sound but it doesn’t really work all that well.
At any rate we’d love to see some spin-off hacks. Assuming the plastic can stand up to the steam heat this would be a perfect robot controller for recorder controlled snake. You can get a recorder for a buck at the right dollar store, and solenoids can be made out of simple materials. If you know of a way to produce the sound yourself, all it takes are a few careful calculations to place the tone holes.
