What was the most extremely home-made radio you ever made?
Not interested in Heathkit, Knight etc., or plans in a magazine article where you made your own PCB - I'm looking for radios where you made your own parts to the greatest extent possible. Capacitors out of aluminum foil, that kind of thing.
Just one requirement: It had to drive a speaker, so that more than one person could hear it at one time. This eliminates simple crystal radios, which are fun and we've all made, and some other simpler designs. I'm interested i hearing about something more unusual and challenging, and how far you got with it.
Of course, the speaker itself may be homemade, e.g. http://www.josepino.com/other_projects/index.php?homemade-hifi-speaker.jpc or http://www.instructables.com/id/Laterally-Driven-Speakers/
Tell your story - what kind of radio, what parts you made yourself or tried to make, how well it worked? Could it have been even more homemade? If this was a long time ago, does it still work? (2nd hand stories are ok, too.)
