If I learnt about Lenz’s Law in high school I must have forgot about it. Watch the cool demonstration above where a stack of neodymium ring magnets are dropped into a copper pipe. Of course copper is a non magnetic metal so the magnets will not stick to it. You would probably guess that the magnets would simply fall at the same rate as if they were just dropped. Well
François Knorreck works as a technician in a hospital in France, but when he isn’t working he tinkers with motorcycles. He spent 10,000 hours over 10 years and spent 15000 Euros on this DIY Sidecar Superbike. After all is said and done the bike looks a bit different than it did when the build began! François has documented some of the build details here. “While this is a very special
After watching the Water Touch Screen video I was expecting to read that there was tons of sensors monitoring disturbances in the water, or changes in pressure due to the introduction of the users fingers. Was I ever wrong, turns out that a Web Cam and some carefully crafted software is all the magic that was needed here! Via: Neatorama “The webcam takes a picture of the surface of the
The first 8 seconds of this short video looks like a nice little robot with 4 wheels and a raising and lowering center platform. After the 8 second mark this robot shows us what is cool with this robot! As it approaches the first raised step the platform is thrust upward to the top of its travel very quickly, the result is a jumping robot! The robotics department of the

This Arduino Steampunk Analog Watch that Matthew Garten built looks fun to use. The video below shows the unit in action with the Biopunk Edition enclosure. I think that the Steampunk version (pictured above) looks much better myself though. There is no shortage of functions either, you can play some games in your downtime. Thanks for the tip Greg. “The materials used in making the watch are Electronics 1 Arduino
Congrats to the guys at YourITronics, their BlueRover robot won 1st place in the Digilent Design Contest. `The idea of a remote controlled rover excites almost every electronics student and when we heard about the Digilent contest we realized that we have the possibility to make such a project real. We decided to build our own remote controlled rover but it had to be different from what we’ve seen before. We came up with
