   As a teenager and young adult I spent many hours assembling electronic kits. My first ham radio transmitter was a Heathkit (as was the next). In addition to ham equipment I also assembled test instruments, home stereo components, computers and modems, and much more. I enjoyed kit building as much as using the devices after they were built (and in a few cases after they were repaired).

    Over the last few decades electronic kit building has fallen victim to advances in electronics, especially the advent of large scale integration. Indeed in many US locations it is no longer possible to find a nearby store that sells electronic parts. However, radio and electronic project kits and ideas can still be found on the Internet. Some of these are of doubtful practical interest—perhaps only good for the fun of building them, while others continue to bring pleasure after assembly is complete.

    The original page became too long, so I split it into individual pages describing kits I have enjoyed putting together, or other small construction projects, as well as one or two explorations that have nothing to do with soldering. Projects are listed alphabetically in the table above—not in the order they were done. The video demos that accompany most project descriptions illustrate highlights and lowlights of the activities.
