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.

Self-cleaning glass windows

Alien technology?  No!  A thin coating of titanium dioxide on your windows will use the UV in sunlight to burn away dirt and wash itself clean with rainwater.


  1. Hi,

    I was wondering, if you could explain, how the thickness monitor works. I will google that by myself, but I really like your videos, and I think others would too.

    I hope I didn't miss that part in one of your previous videos.

    Greetings from Cologne, Germany

  2. If you can deposit titanium on the slide in the absence of oxygen, can't you oxidize the coating on the glass separately, reducing the need to constantly adjust the oxygen up and down as the source material oxidizes?
