Say Bill, what ever happened to that "Mad Scientist's Light Switch"?

Funny you should ask!

I will tell you.

It's on hold because the next step I need to take requires 15 little screw spacers, which I feel certain I ought to be able to buy somewhere, and which I really do not wish to machine by hand one at a time.

I can find them for several dollars each.

I can find them cheap... if I buy 500 at a time.

I was more than a little surprised that not one single electronics or industrial supply house with whom I deal regularly has the exact thing I need.
