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.
