Welcome!

Electronics was my first hobby, starting with a 150-in-1 electronic lab set and working my way up from there. I have no formal training in the field but I've learned a lot from extensive reading and experimenting, from my father, and from my mentor, roboticist friend Mark Tilden during my days at the University of Waterloo.

These days, I use my electronic design and construction skills primarily in pursuit of my other hobbies, or to make life easier on our Norwegian Fjordhorse farm.

This site is a repository of the devices I've built, complete with schematics, circuit board layout, and instructions. The projects are in categories based on what they were designed for, but many have wider uses, so look around. Here are some quick links to the individual sections:

General Interest R/C Hobby Aviation Reviews Techniques/Theory

In addition to the do-it-yourself projects, I'm also starting to review interesting bits of electronic equipment. Unless otherwise noted in the article, all of these are unsolicited reviews of equipment I've purchased myself.

Finally, I've collected a lot of electronic parts over the years for future projects. Some of it I've never gotten around to using and likely never will, so I'm offering some stuff for sale.
