Hack a Day
It would be really fun to do an entire hallway of these levitating wireless lights. This a project on which [Chris Rieger] has been working for about six months. It uses magnetic levitation and wireless power transfer to create a really neat LED oddity. Levitation is managed by a permanent magnet on the light assembly [...]

[Jinha Lee] at the MIT Media Lab created a new interface allowing new ways to modify and play with 3D objects. It’s called ZeroN, and it’s nothing short of a futuristic device straight out of Star Trek. ZeroN is simply a platform for levitating a small spherical permanent magnet in 3D space. It does this by [...]

Hack a Day
[magnetovore] made himself an electronic cello. Instead of pulling a few cello samples off of an SD card, he did it the old school analog way. The finished build is really impressive and leaves us wondering why we haven’t seen anything like this before. [magnetovore] uses a permanent magnet to play each ‘string’. A lot [...]

Hack a Day
[Dino Segovis] is at it again! For this week’s installment of his “Hack A Week” series [Dino] is holding a guitar pickup winding 101. Professional guitar pickups can cost hundreds of dollars, but are all essentially a permanent magnet wrapped in a bunch of wire. Using some cheap headphones, magnet wire, and a spare bolt [...]

Hack a Day
The theory behind speaker operation is pretty simple. There’s a coil that is attached to some type of diaphragm and a permanent magnet. When electrical signals pass through the coil a magnetic field is generated, and that field’s interaction with the permanent magnet causes the diaphragm to vibrate and create sound. But we’ve always assumed [...]

Hack a Day
Above you see a solenoid being used as a digital scale. The magnetic field from the coil in the base levitates the platform above, where a load to be measured is place. This floating platform has a permanent magnet in it, hovering above a hall effect sensor in the base. As the distance between that [...]
