Newcastle Maker Faire 2010
krou writes "The BBC covered the most recent Newcastle Maker Faire, an event which Slashdot first covered last year. From racing power tools, to making music using electric sparks, or a robot that solves the Rubik's Cube in 20 seconds, makers, crafters and hackers were out in force. YouTube has a selection of videos available, and there are some pics on Flickr. And, while it may not be a hover board, there was a self-balancing skateboard."
As a (mostly ex-)skateboarder I feel compelled to point out that skateboards have four wheels, and this is a useless toy which would only have novelty appeal to somebody who never took the time to actually ride a board in the first place.
The appeal of skating is not about having the board be in control of your movement, and there is nothing safe about any of it. You will fall and you will hurt. Mastering that is what makes you enjoy yourself.
