I ran across OpenYou dealing with hacking health hardware. A subject we are sure to spend more time on over hte next few years.
OpenYou.org seeks to be a central resource for news about open source development on health hardware. It provides lists of libraries and applications from the open source community, to help developers learn more about the devices that let them learn about themselves.
In addition to pointing to other libraries and projects, the OpenYou team also actively reverse engineers and develops drivers and libraries for whatever health hardware they can find.
Kyle Machulis is an engineer working in such fields as robotics, teledildonics, biometrics, audio research, and whatever else he decides is interesting and/or can do silly things with. With reverse engineering as a hobby, he has been part of multiple health hardware projects, including drivers for the Lightstone, Omron Blood Pressure Monitor, Omron Pedometer, and multiple consumer EEGs.
