This is basicaly a "radio that doesn't require any batteries".
It's very easy to build one yourself since only ~5 components are needed and a long-ish wire.
A variable resistor knob is then used to switch between radio stations.
Though it will only catch AM if I'm not mistaken.

- ogig 3y agoMy dad, whose dad had a radio and tv repair shop, got me a kit for making one when I was a little kid. I spend the day coiling the wire and following the instructions. When I was done and the artifact captured radio waves I was so excited! It's one of those vivid memories from childhood, a moment that put me on the path for a technology focused career.
- dekhn 3y agoradio is a gateway to abilities that some consider to be unnatural (my grandpa gave me a shortwave and explained I could receive far-away signals due the radio signals bouncing off the ionosphere. It was my introduction to numbers stations, but I never found radio that interesting, when I had the internet available)
