HoloDesk: More Augmented Reality Pr0n

Microsoft Research is up to their usual cleverness: HoloDesk is a novel interactive system combining an optical see through display and Kinect camera to create the illusion that users are directly interacting with 3D graphics. A virtual image of a 3D scene is rendered through a half silvered mirror and spatially aligned with the real-world […]

Testing a DIY Triode

Testing a DIY Triode

Sébastien Bourdeauducq of /tmp/lab and the Milkymist project scored a DIY vacuum tube, and set about testing it out. I was curious to see how well the PWL triode performed. So I made a little test to measure cathode emission and amplification. The first step was to build a variable high voltage power supply, since […]

Apple ADB Mouse Soap

Apple ADB Mouse Soap

For folks who appreciate a good dose of nostalgia with their personal hygiene, Kylee Lane’s Apple ADB Mouse Soap will definitely hit the spot. Although, to be perfectly honest, I never really associated the ugly beige color of the older machines with cleanliness, but to each their own.

3-Servo Walking Robot – The Latest in Hobby Robotics

How do you make a walking biped robot, with only 3 servos? In this episode of The Latest in Hobby Robotics, Frits Lyneborg from letsmakerobots.com shows you his inventive way of doing just that.

The programs used the robot on the video can be downloaded here: letsmakerobots.com/​node/​29379

Tools needed are just very basics, like saw, drill, ruler etc.

Materials are the 3 servos, some wood (4 paint sticks), hot glue, a couple of screws and some thread locking fluid. The servos are controlled by an AXE230, and batteries are used as balancing weight.

You can use either 3 “normal” batteries, or 4 rechargeable, you just need somewhere between 4.5 and 5.5 volts.

You can adjust the the height of the batteries, and there are several parameters to adjust in the programming code as well, to make your robot walk well.

You can also port the simple code to any other micro controller of your choise, and add sensors, arms and more to your own robot.

If you have never build a robot before, the best place to start is probably here: letsmakerobots.com/​start
