Dr. CockroachJust dug out something from my junk box of parts that I almost forgot about.
I used to be very active with crystal radios and one day I wanted to see if I could make my own variable capacitor. Using two soda cans, a cardboard ( what else ) loo tube , electrical tape and a plastic tube, I was able to come up with this. Wired up with a crystal radio set it tunes quite nicely on the mw broadcast band here in the U.S.
Hope this gives everyone a smile :-)

Nice!
I've been meaning to try to 3D print some radio parts - coil forms that change distance with a lever to control feedback in a very simple regen. I wonder if you could make some variable capacitor parts that just need to be covered with foil?
Are you sure? yes | no
Hi there Ted, I think that something like the Crosley Radio book style condensers ( yes it is an older word ) would work out well for a regen set. I have not messed with my regen for over a year. The coils are just simple toilet paper tubes and loose coupled much as your lever. I could give making something a like a book style a try.

Hmmm, if I need to replace that trimmer-cap on my PC/XT mobo, maybe this is the way to do it :)
