PlayStation Move and a turntable used to track the Earth’s rotation

Posted in DIY by Conner Flynn on February 21st, 2011

Fancy yourself an amateur scientist? Do you want to track the Earth’s rotation from your home? Well, if you have a few simple tools, you can do just that. The device above is called Copernitron and features a PlayStation Move controller, a turntable, and a homebrew Helmholtz coil which cancels out interference caused by our planet’s magnetic field.

It sends data to a Linux PC via Bluetooth and measures the Earth’s rotation, locates geographic north, and determines altitude. This is achieved by measuring the controller’s movements as it spins around at 45 RPM.
