Watermelon air boat

We think you’ll turn a few heads in Central Park if you’re driving a water melon around when everyone else is piloting sailboats. This watermelon is both sea worthy and radio controlled thanks to the work which [Starting Electronics] put into it.

We used this image because it shows you what’s inside of the hull, but you don’t want to miss the thing motoring around an above-ground swimming pool in the clip after the break. The hollowed out shell is quite buoyant and has no problem staying afloat and upright with the addition of a propeller. The parts from a remote control airplane kit have been mounted on a wooden scaffold. This provides plenty of thrust with a servo motor moving turning the prop for directional control. There is no dagger board so the craft is a bit slow to respond to turns. But how responsive do you expect a floating melon to be?

Becoming Gallagher in your mind

The folks at the Louisville hackerspace LVL1 created the handiest and the dandiest kitchen tool you’ve ever seen. It’s not a slicer, it’s not a dicer, or a chopper or a hopper; it’s… a Star Wars Force Trainer that blows up watermelons.

The project is called Mind Over Melon and was created by [Chris] and [Brad] at LVL1 for the CONNECT at Bernheim festival this past weekend. The idea behind the build is allowing people to explode a watermelon with their mind using a Star Wars Force Trainer EEG toy.

The build features the Force Trainer attached to an XBee module, wirelessly connected to the ground zero of watermelon destruction. When the operator of the device concentrates very hard, a series of LEDs light up and a solenoid dumps a shot of compressed CO2 into a watermelon.

[Brad] tells us instructions to build your own mental Sledge-O-Matic will be available on the LVL1 wiki shortly, but until then enjoy this video of the Mind Over Melon being featured on WHAS11 news.
