As part of their robotics exercises and entering competitions with the, the "Antipodes" team of female students have created an excellent example of a magnetic levitation demonstration using Arduino and circuitry, some LEGO and a lot of magnets. By studying the theory of magnetic levitation they have reproduced a working system that allows for speed and direction control as well as track-end avoidance and more. It's amazing what can be done with some time and effort, and the results are demonstrated by a team member in the following video:
That's a whole lot of awesome - so visit the project website for complete details and tutorials on how to recreate it yourself. And for more, we're on twitter and Google+, so follow us for news and product updates as well.
