Welcome! I am an engineer, programmer, designer, and all-around geek. 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.

A Javascript Resistor Color Code Calculator

I recently built a small app that calculates a resistor's value based on color coding. This was an educational exercise in plain-vanilla javascript and old-fashioned html+css, although using jQuery would have saved me a lot of typing if nothing else. I tried to keep the color definitions and so forth as D.R.Y. as possible, going so far as to populate the select boxes from javascript using tedious DOM hacking. I'm sure many possible improvements will be immediately obvious to the attentive reader.

A Stainless Steel and Cedar House Number Plaque

Here's something I made recently. For many years my house number was marked by stainless steel numbers from Blomus that have bosses on the back so that they float off of the wall surface somewhat. When we painted the house gray the stainless just didn't have enough contrast against that background, and since I had done a gray-plus-wood sort of theme in the recent bathroom renovations I decided to extend this to the exterior of the house with a sort of wood plaque behind the house numbers.

Lasercut Storage Bins

I have a small workshop space in a spare bedroom at home. Like many people that work in small shops I try to find ingenious ways to use every part of the buffalo. My latest improvements are some laser-cut plywood storage bins for small tools and parts, designed to mount to the sides of the hutch over my electronics workbench.

Macro Photography Light Tent, Mk.2

I've upgraded my light tent for macro photography yet again. I reused most of the PVC components from the Mk.1 design but replaced some of the pipes to make the tent wider; I had sometimes been limited that way with the original design. I'm keeping this one at the office instead of at home and wanted to be able to accommodate one of the 23-inch wide patch panels I've designed, which requires a significantly wider light tent.

Upgraded frame on IKEA table

I designed the Mk.2 around some left-over IKEA GALANT parts we had in the office, which yielded a table 47.5 inches wide and 31.5 inches deep. I bought some M10-threaded caster wheels and screwed them into the bottom of the GALANT legs to make the table mobile for ease of re-configuring my office area.
