Anyone built a crystal radio kit?

I had one of those from radio shack too. Looks the same except for the artwork.

The Xtal Set Society sells a range of crystal kits:

You can also buy a basic kit from Antique Electronic Supply:

If this will be a group project, you might consider building a kit yourself beforehand, and trying it out in the location where your group will be working. It might be disappointing if everyone completes their project and you hear a chorus of "Can you hear anything?" "I can't hear anything!"

I'll echo the test it first suggestion.

And, keep in mind that a crystal set needs a pretty good antenna and a good earth ground to function properly.

I built the oatbox radio a few years ago. It was pretty easy and didn't take much time other than ordering the parts.
