Play some Super Arduino Bros. tunes with percussion

Have you ever wished your Arduino project could play tunes, or even just note-based sound effects? Connor Nishijima has, and that’s why over the last three years he has been hard at work developing Miduino—a free web service that enables Makers to automatically convert their MIDI music into ready-made sketches. Unlike any built-in Arduino noisemaking functions such as tone(), Miduino’s output is polyphonic–meaning you […]

Listen to a computer hardware orchestra rock out to Nirvana

What do you get when you combine 64 floppy drives, eight hard disks, and two scanners? An incredible computer hardware orchestra that can rock out like Kurt Cobain. Created by Pawel Zadrozniak, the Floppotron is not only capable of covering ‘90s hits like Nirvana’s “Smells Like Teen Spirt,” but can play other tunes ranging from Darth Vader’s Imperial March to the theme song of […]

Grab things with an Arduino robotic gripper

Recently-graduated high school students Sam Baumgarten and Graham Hughes have developed a pretty rad robotic gripper with the help of Arduino and 3D printing. The gripper itself consists of three large hobby servos joined to the fingers with a linkage. The underactuated fingers have a force sensor under each contact point, while the control glove is equipped with tiny vibrating motors at the fingertips. […]
