Welcome to my little corner of the world... The purpose of this site is to document my various interests/projects and make them available in the hope that the information might be useful to others. Most of my interests involve some combination of the following: family, community, traveling, computers (technology in general) and mapping.

Here is a selection of my latest projects:

Race Timer

A do-it-yourself Pinewood Derby race timer based on the Arduino Uno. The robust and flexible design allow the timer to be easily constructed and modified to meet your specific needs. Information and photos to aid in the construction of the race timer including circuits, software and the hardware enclosure.

Car Scale

A do-it-yourself car scale for the advanced Pinewood Derby racer. Three load cells measure the total weight of the car and the distribution on each wheel. Information and photos to aid in the build of the car scale including circuits, software and a hardware enclosure.

NPS Map Symbols

Icon packages that allow Locus Map users to utilize the same standard cartographic symbols that are used on National Park Service maps. There are over 250 symbols which are separated into 16 categories.

LED Bitmask Tool

A small Windows utility to aid in creating custom bitmasks for Adafruit LED displays including the popular 7-segment, alphanumeric, and mini 8x8 matrix displays.
