In the midst of photographing my boards and writing up docs I was thinking, “this all seems familiar for some reason…”.
Here’s the ITP tutorial on High Current Loads. It covers pretty much everything we did today and then some. There are many excellent tutorials on ITP’s site, it’s a good first-go-to site for how to do various things with the Arduino.

Here is how to hook up an infrared rangefinder sensor (the Sharp GP series).
Here is a rich and informative resource on mechanisms. “KMODDL is a collection of mechanical models and related resources for teaching the principles of kinematics–the geometry of pure motion. The core of KMODDL is the Reuleaux Collection of Mechanisms and Machines, an important collection of 19th-century machine elements held by Cornell’s Sibley School of Mechanical and Aerospace Engineering.”

I thought some people might find the free software Dia to be useful in future projects. It’s a diagram-drawing program, and does a great job of helping you draw out circuits in only a few minutes – often easier than explaining in English which wires go where 🙂 . (For linux, Windows, and Mac via macports.)
