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.

Your toothbrush is worn-out!

See how your trusty toothbrush becomes worn out.

Special thanks to Harri Lähteenmäki  and Johannes S. Zwilling for sending me the smooth zoom footage of the tungsten filament, and showing me how to use After Effects to get a much better effect.  I really appreciate it!  http://www.videocopilot.net/tutorials/earth_zoom/

Smooth zoom video from SEM

I manually interpolated the sequence from about 15 single frames from the SEM.  Smooth zooming is not possible on the instrument natively.
