Here's an interesting Open Source Hardware kickstarter that I recently backed. I thought others might find it interesting too:
OpenBCI: An Open Source Brain-Computer Interface For Makers

OpenBCI is a low-cost, programmable, open-source EEG platform that gives anybody with a computer access to their brainwaves. Our vision is to realize the potential of the open-source movement to accelerate innovation in brain science through collaborative hardware and software development. Behind the many lines of code and circuit diagrams, OpenBCI has a growing community of scientists, engineers, designers, makers, and a whole bunch of other people who are interested in furthering our understanding of the brain
In the OpenBCI Brainwave Visualizer above, the graphic at the top left shows the electrode placement positions for the experiment. The color intensity of each node indicates the EEG wave amplitude at that region of the scalp [...] The screenshot was captured about 4 seconds after our test subject closed her eyes. There is a high amplitude waveform seen clearly in channels 5-8, which are placed on the back of the scalp. Notice a spike in the FFT graph at about 10-12Hz. This shows a predominance of alpha waves in the occipital region of the brain, which is what one would expect to see when the subject’s eyes are closed and the visual cortex has nothing to do
Anyone up for some brain hacking?
