Members from the London Hackerspace recently got a little on-air time with a ping pong ball launcher. They were invited to build something for the Click show on BBC. The launcher that they built responds to hash tags on Twitter by barraging the audience with balls.
The hardware was built in two parts. The first is a dispenser that responds … Read the rest

This makes for a prototype-friendly space, protecting the copters from hard landings and the … Read the rest
If you’ve been lusting after your own glowing display we’re here to help by sharing some simple building techniques that will result in an interesting project like the one you see above. This is a super-accurate clock That uses ping-pong balls as diffusers for LEDs, but with a little know-how you can turn this into a full marquee display. Join … Read the rest
[Alex] wrote in to let us know about this Kinect controlled LED wall that was whipped up at the Tetalab hackerspace in Toulouse, France. The wall, which was built earlier in the year, uses some MAX7313 LED intensity controlling shift registers. Each gets its own board and controls the intensity of sixteen different red LEDs. They’re embedded in the wall … Read the rest
[Mitchel Humpherys] and his fellow developers didn’t just develop a maze-solving algorithm, they also built a ping-pong ball maze platform that is computer controlled. Using a webcam the computer picks up the high-contrast maze by peering down from above, calculates the solution, and moves the ping-pong ball to the goal using two different tilt servos controlled by an 8051 … Read the rest
