I work on Virtual Reality and other hardware at Valve.
For my previous day job, I built computer peripherals such as keyboards, mice, and joysticks that were meant to be used inside MRI machines. My company, Mag Design and Engineering, sold these devices directly to researchers at academic institutions who use them to publish scientific papers in peer-reviewed journals.
After work, I spend time on many different types of projects that usually involve circuit design, machining, material selection, and general fabrication/hacking. My favorite place to be is my home workshop.
