About Me

My Photo

I previously worked on Virtual Reality and other hardware at Valve.  I currently work at Google[x].

Prior to starting at Valve, I built computer peripherals such as keyboards, mice, and joysticks that were designed to be used inside MRI machines.  My company, Mag Design and Engineering, sold these devices directly to researchers at academic institutions who used 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.

High pressure gas cylinder transfer

I transfer high pressure ethylene gas from a rental cylinder to another cylinder that I own.  I use a cooling water bath to condense the ethylene and transfer as much mass as possible.

Cryogenic Machining: Custom rubber parts

I demonstrate the process of cryogenically freezing rubber, then CNC milling it into a custom shape. This avoids the need to injection mold or cast rubber parts.
