I'm Hal Breidenbach, a retired software engineer but still a tinkerer and maker. I keep myself busy with a variety of different projects, everything from home renovations to building robots. I enjoy going to the annual Maker Faire at The Henry Ford Museum.

I live in the United States in Ann Arbor, Michigan with my wife Cathie. Our three daughters have long since left the nest. Now that we've got the time, we're doing our best to travel the world. Since retiring in 2008, Cathie and I have traveled to Central America, Cuba, Europe, India, Peru, Russia, and Turkey. We often travel in groups with a company that arranges for interactions with local cultures. Of course we've been to Canada many times, as it's right next door. We've also been to America's final frontier, Alaska.

When we're not globetrotting, we stay active contra dancing. In the winter we go cross-country skiing and during the summer we take our kayaks out on the Huron River. We used to canoe camp but we haven't lately, so we've decided to sell our classic 1918 wooden canoe.
