Hopefully, somewhat of an inspirational post. While searching the parts bin for something to tack together, I came across a couple large air variable caps. What to make of them?
Well, a crystal radio, of course!
A 2-inch plastic tube with about 40 turns of high gauge insulated wire
Coupled to an old-school crystal earpiece with a germanium diode
...and the air variable capacitor...
you have a rather crude, but quite functional AM receiver.
The earpiece sits at my elbow and a couple of stations can be heard when things are just right, a couple more when everything else comes into place and I lean into the cone.
Hmmm...not more, nore less than I was expecting; entertaining nonetheless...
This is actually the poorest design, but will pursue significant improvements in the coils, their coupling, detector, and finally class of the set, perhaps finished in a deep oak slab free of clutter while presenting luxurious controls; presuming that I do not again fall victim to function over form...
