AM Radio That Works!

3D model description

I'm thrilled to unveil my new 3D printed AM radio! I was inspired by the diy crystal and foxhole radios of the early 1900's, but I created my own design to be as simple as possible. I made a few animations to help assist in explaining how this mystifying device can work with so few parts.

The video will explain the assembly so I hope you like it and thank you for watching!

Materials:
1 Piezo Earphone
1 Coil of 24 AWG Magnet Wire (aka Enamel Wire)
1 1N34A germanium diode
1 small piece of aluminum foil
1 paper clip
1 package of Hildie & Jo 45 Cord Ends (3 small 5x10mm Springs)

These should be easy to find online. The springs I got are sold at Joann Fabrics. Search Silver Cord End Springs but any similar 5mm diameter springs should work.
