Welcome! I am an engineer, programmer, designer, and gentleman. You may be interested in some of my electrical and mechanical projects. Take everything you read here with a grain of salt and remember to wear your safety glasses.

From the Fury of the Norsemen, O Lord Save Us! (New Year's Eve Part 1)

New Year's Eve 2007 was the latest in what has become a Martinson tradition: a themed costume party. The theme this year? Vikings! As always, this party involved a great deal of creative work beforehand in making the costumes, props, fireworks show, and all the rest of what our guests have come to expect out of a not-so-typical New Year's Eve. I can't publicly thank everyone responsible for these preparations, but you know who you are, and I know what you did. Thank you all. This post (and the ones to follow), however, is more for the benefit of those who weren't at the party, but are interested in some of the projects completed for it. First, my viking shield:

This is probably the only costume item that bears any similarity at all to actual viking kit, or at least measures up to a reasonable re-enactor's standard. Yes, it is plywood (11/32") rather than joined planks, and the fanciful dragon motif (taken from a shield on display at the Norway pavilion in EPCOT center) was probably never seen in actual dark age combat, but other than that, it's not bad. The plywood blank I cut out with a jigsaw. The steel boss was made by an armourer named Mad Matt (it's the "satin-finished" round boss available on his site)—a solid, economical choice I'm very happy with. I also applied an edge-banding of 3" wide rawhide strips (soak a large rawhide dogbone till it unravels, apply when moist and flexible) nailed over the edge with blued carpet tacks. The grip in the back picture is just a bit of hardware-store mild steel bar, drilled and riveted through to the boss.

Comcast DNS Broken

I've been getting a few complaints about various sites not being accessible by Comcast users and discovered that quite a lot of domains are inexplicably not resolved by their DNS servers. Here is an extremely partial list, generated purely at random:

These are all popular blogs, and none of them work on Comcast's DNS. So I switched to OpenDNS, a free public dns service. You can sign up for an account, which gives you access to some features like porn-filtering and statistics on DNS usage. You don't have to have an account, however, you can just go ahead and start using the servers: 208.67.222.222 and 208.67.220.220.

The Audi Driving Experience

Believe it or not, being a member of junk-mailing lists, in particular those targeted at consumers of high-end "lifestyle" products, can be good. Being a close friend or relative of a person on those lists can be even better. This second approach has gotten me past the door of a surprising number of product launches, luxury car test drives, and top-shelf whisky tastings, usually in the company of my cousin Torm, whose tastes are somewhat better funded than my own and whose addresses are in somewhat wider circulation. But it was this October that Torm, my friend Jay Wilson, and I headed south to the Homestead Speedway to participate in the ultimate free-of-charge luxury-goods marketing event: the Audi Driving Experience. Click on the link to read more and be prepared to accept that all Audi requires from you is a driver's license and the flimsiest pretense of being richer than you actually are to stuff your head into a helmet and set you loose on a racetrack piloting several hundred thousand dollars worth of powerful machinery.

“Desalination Boys”

Brandon Moore and I have made it into local glossy Boca Raton Magazine with our desalination project. Many thanks to Kevin Kaminski for the article; many thanks also to the photographer, whose name escapes me, for taking on the thankless task of making two scruffy geeks look good. If you live in Dade, Broward, or Palm Beach county, go and buy a million copies, on newsstands September 1.

Fixing Awstats on Mediatemple DV

So far I'm relatively satisfied with my new Mediatemple DV hosting service. I have, however, discovered a problem with the Mediatemple configuration of Awstats, the logfile-analyzing web statistics package I use. Awstats can't find its images because the path is broken in the standard Mediatemple installation - browser and country icons are missing, and the bar graphs are empty:

Here's how to fix it.
