New headstages for open-ephys

Josh and I just assembled the first prototypes for the new and improved 32 channel headstages for the open-ephys system, an open source system for extra-cellular electrophysiology.

These are smaller than the previous ones even though they now feature a standard omnetics connector, and thanks to the new intan RHD2132 chip, work via low voltage differential signaling, so long cables should not be an issue. We also managed to fit a small accelerometer on these to be used for behavioral analysis, sleep scoring, or artifact rejection etc.

The picture shows a headstage with a vertical omnetics connector for testing. For use in experiments, you'd have a right-angle connector that sits flush with the board.

Check them out on github, or open-ephys.org
