Electronic Project Museum

sine1

These pages are dedicated to my electronics projects. I have been designing and building electronic equipment as a hobby since I was a teenager. There are several audio projects, two pieces of test equipment, a computer, and some miscellaneous projects.

Everything on these pages I have designed and built myself. The designs include both analog and digital circuits. The construction technique is perf board and point-to-point wiring. The technology employed dates mostly from the 1970s and 1980s. I have included the schematics for a few of the smaller projects, but even those would be considered advanced projects.

The real electronic project museum is, of course, my house. Through the Internet, you can tour my online museum anytime!
