We also constructed crystal radios, which picked up signals from all over the world and only had $3 in parts--including the headphones. I'm amazed that those old projects have been around this long, and the only thing that has changed is the material used for the speaker cone. WOW!

Oh, I almost forgot. The sound level was so low that at my age I probably wouldn't be able to hear any sound from the homemade speakers. She said the hearing was the third thing to go.

Cheers,

Gary
