Feedback To Source

@all

According to this schematic I found on a search. The blade occupies the place of the galena rock. So it is very possible that the blade goes on the direction depicted here.

@ Jesus:

I have read somewhere that you need a special type (old style) earphone which works on low input.  Something about the way they used to make them works well with these units.  As I said, I don't know for sure, just read it.

Here is a link to my Bedini replication on youtube.  It is not feedback to source.....yet, but I am going to work on that now that it is up and running.

Here is a link to a site where I read about the pizo earphones being required.

This guy has a great site and once you are there on the link page I sent you to, look around.  He has many working designs for crystal radios as well as other cool projects.  I hope this helps.

Thank you @pirate !

I saw your video and the motor while is spinning gives the sensation that it is not moving at all.
Nice job!!!

Thank you for the radio link.

On the Radio Shack electronic lab I have, there is an earphone included that will be used to build some kind of ant hearing device or something. That earphone is just as the one needed for the crystal radio.

When I visited the radio link, I noticed that this was the site where I took the first blade diode from. I had lost the link. Thank you for giving it back to me.
