Controlling Katamari using a real life ball interfaced with an Arduino

Another wonderful concept using Arduino. This one uses a steel ball as the interface and a regular laser mouse as the pickup device, that info goes into an arduino which encodes it through a digital potentiometer and sends it on to a controller.

MAGIC !!! Coolest Arduino Hack EVAR!!!

Okay, so this is the kind of stuff I want to do with my recently acquired arduino kit!




I think instead of using the knocks, a grid of magnetic sensors would be much more appropriate. What you do is carry a small magnet around on your keychain (if you don't already) and wave it at the door in a given pattern right,down,left,right and the door magically opens

Now that could take care of giving temporary access to premises to whomever you wish.
