This is an older drawing of a hut from somewhere in Southeast Asia, after a photograph in Architectural Digest. I drew this with a black Pilot G2 05 pen in the sketchbook I was using at that time.

I've redesigned my personal site and blog, and would appreciate criticisms or comments. The layout adapts to a wide variety of screen widths using CSS media queries; try scaling your browser window or looking at the site on your mobile phone to see what I mean.

As a way of trying out github for myself I uploaded a small script that iteratively solves the Colebrook equation for the Darcy-Weisbach friction factor, which can be used to estimate head loss due to pipe friction; this played a very minor role in my recent MSEE thesis. The script runs in GNU Octave and it certainly should run in Matlab as well, although I haven't tested that.

Some of my projects have been drawing attention from Maker circles lately. I'm very excited that the Color Changing Doorbell was featured on the blog of my favorite magazine MAKE.

Also, a website called BuildLounge was kind enough to link to my serial-controlled fireworks igniter, under a category of "Explosions". Welcome, new visitors from these sites!

These pictures are from an Audi Owner's Club caravan to Key West on May 21, 2011 using Jay Wilson's brand new Audi S4; a fun trip!
