 Projects
Like many an electronic hobbyists, I've a reasonable collection of past projects. Some quite successful and useful, some pie-in-the-sky dreamer material, no few that were never followed through to completion and many that never even got started.

I've taken the time to write up some of the more useful (or perhaps just interesting) projects which were completed.

There's also a project photo gallery.
