We have all seen these floating globes in the novelty stores and online. How would you like to build one? J. Hodgie has put together an article that will walk you through the required steps to make your own. The code for the Atmel ATMega168 Microcontroller is also provided. The place the object floats at depends on the weight of the object and the power of the magnets in the object. The height is set by holding the object under the magnets and sensor and pushing the button. The object floats at the point where the force of gravity down equals the force of the magnets pulling up, which allows it to use non-industrial electromagnets and less power to float. The program also dynamically adjusts so the object is always at the perfect height.”

I have one of the aforementioned globes, and it works by adjusting an electromagnet’s strength based on an EMF reading several times a second.
Also, the ones you linked to all state that they need to be plugged in also.
Just thought you guys might want to know, for the sake of accuracy in the article.

This is cool.
But how does one make this with permanent magnets (so that we dont need battery’s etc)?

does this have to attach to a computer?
what do the cables end up going to?
