Funds raised for DIY EEG project.
Robert found some likeminded brains:
"We put together an EEG kit for a workshop we held on the 25th "teaching people to integrate EEGs into Art". We were pretty amazed at peoples response in actually being able to see their brainwaves. We'd like to share that amazement with as many people as we can. While I think I'm a pretty swell teacher, I realize that physically we can't hold a workshop for everyone. And so the next best thing would be to offer the EEG as an affordable Kit.
We should perhaps consider following their approach to funding.

TL;DR: We'd like to use this kickstarter to spread our love for EEGs and more generally Neuroscience, in the form of an easily put together kit."

Fixing bluetooth connection
As it turned out the BlueSmirf Bluetooth module by default listened at 57600 baud, while the microcontroller was sending out bits at 115200 baud. Sending commands using Putty to change the baudrate solved the problem (but not after also discovering a defective flatcable connecting the two board. Always make your own!)
