Robo-hand plays RPS - This is a project my son Gordon's robotics team put together in the last 2 weeks for the McGill Robot Club. The player's hand is recognized with OpenCV and the robot hand reacts. Kind of cheating, actually - but a cooler project this way. The video shows an untrained hand. If the player is already in the OpenCV database the reaction is almost instantaneous. Gordon did the mechanical design and build.

I'm not making this up. Crafting with Cat hair is a real book. Starting from the premise that you can make felt from any animal fur - why not clean up your messy cat-haired house and get something out if it?

Here's some video of the TinyG demo we showed at MakerFaire NYC 2014. Riley built this monster machine (over 1 meter long) to illustrate stopping pendulum motion in 3 dimensions using precisely timed and executed moves.

Found at a Chinese restaurant. Someone at Microsoft really should have looked into this.

Looks like early Sunday morning in Amsterdam. They look hung over and she's a little off key at first, but it's great. The second tune they do (about 4:14) is the one you may have heard - Golden Age. They also look like they are waking up. I love the tram bell in the background - sounds so Amsterdam.
