This project is based on some hack of a mind flex toy containing a so called "neurosky eeg" chip. Having a sensor connected to your skull this system can meassure several waves emitting from the brain, also called brainwaves. The Idea is to combine this system with some camera based monitoring system that will watch a test subject while sleeping and recording the corresponding brainwaves for later analysis of brainactivity and body movement.

Other use cases do exist, this was the only one i could come up with that involves sleeping in the office ;)

The project is based on this hack:

The required hardware - a mindflex toy is available, however not yet modded to provide the data to a arduino or other microcontroller for processing. I'm willing to solder in the connector if somebody is interested to play with it.
