We’ve seen a lot of interesting MIDI controllers, but this one uses some unconventional materials. The World’s Coolest Keystroke, built by [Audiobody], is made from a combination of tennis balls, Lego bricks, servos, and switches.
When a tennis ball is lifted up, a Lego arm is actuated. It looks like a servo is used to move the Lego arm so it hits a switch. An Arduino is used to detect this and send a message to their computer.
They use the device to control Ableton Live and play different clips depending on which tennis ball was removed. It’s an interesting way to control sound with a tactile interface, and it looks pretty nifty.
After the break is a short video of the device in action, but [Audiobody] says that they will be releasing more information soon. We’re looking forward to seeing other interesting controllers that they have in the works.
