不会传附件 我把介绍翻一下吧（人工翻）
introElectromagnetic Floater
This Instructable will show you how to make a device that can float almost any object with a magnet in it.
这次Instructable将会告诉你如何制造一个几乎可以悬浮任何含有磁铁的物体的小机器。
It is much like the floating globes you can buy, except it works by balancing the forces of permanent magnets with electromagnets, rather then simply using combinations of permanent magnets.
This is done by using a microcontroller and an IR sensor to detect where an object is floating below. Then based on a set value, the microcontroller uses the electromagnets to to hold the floating object at a given height.
他与你买到的悬浮地球仪很相似，除了它用电磁铁来平衡永磁体，而不是仅仅用两块永磁体。这个设计用MCU和红外传感器来侦测下面物体悬浮的位置。然后MCU根据设定值用电磁铁来吧悬浮物固定在适当高度。
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.
物体悬浮的位置取决于物体的高度和物体内磁铁的强度。高度的设定需要把物体放在磁铁和传感器下然后按按钮。物体悬浮在磁铁拉力和重力的平衡点上，并用非工业级电磁铁和少量电能达到这一点。程序也会动态调节以使物体悬浮在完美的位置上
I decided to make the electromagnetic floater because I have always been fascinated by the floating globes in the store, but I never wanted to pay their prices, and I never liked how they only floated objects that you had to buy or came with it. So, I decided to make my own that could float anything with a magnet. The results are what you see here.
我决定制作电磁悬浮器是因为我被商店里的悬浮地球仪迷住了，但我从不想付钱，我也不喜欢你买的东西只能漂浮一样东西。所以我决定制作我自己的机器来用磁铁悬浮任何东西。结果如你所见。
