This is my Foxhole Radio, i built it for less than 5€ , it's very easy to make that's why i put the plan so you can make one at home too, if you want :D .. This radio works with radio waves transmitted by AM transmitters received through the antenna, the coil then the Germanium diode. The coil and the diode transform the signal to audible waves, send to the speaker and to your ears.

What you need to make it :

- An earphone ( or some computer speakers but you have to build a lil' adaptator to plug it, that i did)... mines comes from an old phone, it's about 2000 Ohms.

- A variable capacitor, mines' from a children AM radio, but you can use a razor blade and a pencil instead of this, just google it to know more ;) ...

- Some electric wire to make the antenna and connection to the ground ( or to a radiotor, that is connected to the ground )

- Copper wire, we don't care about the diameter .. it only has to be coated. Do about 100 joined loops around a ..

- 4 centimeters (about) diameter pipe.

- A germanium diode, i think every kind of those diodes'll do.

Here are the plans :
