No batteries, no problem. The joy of listening to AM broadcasts without any power source has always been fascinating by many including myself.
When I was younger the Science Fair Crystal radio set was my introduction to AM and its wonders. Fast forward to 2008 and my interest peaked again in the hobby and had me interested in building my own kit or buying one already made.
The choice was easy once I found out about this little wonder. The Howes CR-5 was perfect, and it was very inexpensive for all the labor and materials...

Trying to grow crystals from home with a kit
Besides the kit you will need boiling water, paper towels or newspaper and better gloves cos the ones they provide aren't very good
It was quite fun though it needs alot of time.

How to Make/Build a Crystal Radio
Step-by-step instructions for making a tunable crystal radio. This is a radio that gets its power from the radio waves. I made it almost entirely from junk except for the diode (1N34 germanium diode) and the earpiece (though you can use a speaker from a phone instead.) The capacitor is made from aluminum foil and a paper towel roll. The coil is rolled on a toilet paper roll. The wire is enameled magnet wire. For the antenna I use a 15 foot wire laid out on the floor. For the earth ground I connect a wire to the ground in the household wiring.
I originally got this circuit from the book "Radio Receiver Projects You Can Build" by Homer L. Davidson.
For this circuit, the diode must be germanium. The following is a partial list of germanium diodes that should work:
1N34A, 1N60, 1N91, 1N119,...

How a Crystal Radio Works
Full details of how a crystal radio works, right down to the electron level.
We start with a demonstration of all the parts in action, showing how the radio waves interact with the antenna and antenna coil to produce a fluctuating magnetic field, which induces electron flow in the tuning coil, which works with the tuning capacitor, which is followed by the diode and crystal earpiece. We talk about why a leaky germanium diode is needed with this particular circuit or how a bypass resistor can be used instead.
That's followed by how the tuning is done using a tuning coil in parallel with a tuning capacitor, which together are tuned to a resonant frequency the same as the radio frequency by adjusting the coil's inductance and the capacitor's capacitance.
Then we show how a radio wave is fo...

How a Crystal Radio Set Works
Discover how a crystal set radio works and some of the hints and tips in building them.
Crystal radios were used in the early days of radio broadcasting. They used crystal detectors that were known as Cat’s Whiskers because of the thin wire that was placed onto the crystal itself. These radios required no batteries, all the power for the earphones coming from the signal that was received.
This video describes how the tuning and selectivity of the crystal radio works. It shows how the tuning capacitor and inductor may be changed to tune in different stations. It then describes the detection of amplitude modulated signals. It shows how a diode detector works. Finally it mentions the transducer and why only headphones are normally suitable for use with crystal radio sets.

Step-by-step instructions for making a tunable crystal radio. This is a radio that gets its power from the radio waves. I made it almost entirely from junk except for the diode (1N34 germanium diode) and the earpiece (though you can use a speaker from a phone instead.) The capacitor is made from aluminum foil and a paper towel roll. The coil is rolled on a toilet paper roll. The wire is enameled magnet wire. For the antenna I use a 15 foot wire laid out on the floor. For the earth ground I connect a wire to the ground in the household wiring.
I originally got this circuit from the book "Radio Receiver Projects You Can Build" by Homer L. Davidson.
For this circuit, the diode must be germanium. The following is a partial list of germanium diodes that should work:
1N34A, 1N60, 1N91, 1N119, 1N270, 1N277, 1N283
The following are not germanium diodes and may need a long antenna or a powerful radio station nearby to work:
1N4148 (silicon, found on a lot of circuit boards), B16 (zener diode), 1N5060 (avalanche diode)
The crystal earpiece (piezoelectric earphone) and/or 1N34 germanium diode and/or air core variable capacitors can be ordered from most of these sources:

https://store.scitoys.com/radio-kits-and-parts.html (their variable capacitor is for if your coil has a ferrite core and is smaller than the one in this video)

Full details of how a crystal radio works, right down to the electron level.
We start with a demonstration of all the parts in action, showing how the radio waves interact with the antenna and antenna coil to produce a fluctuating magnetic field, which induces electron flow in the tuning coil, which works with the tuning capacitor, which is followed by the diode and crystal earpiece. We talk about why a leaky germanium diode is needed with this particular circuit or how a bypass resistor can be used instead.
That's followed by how the tuning is done using a tuning coil in parallel with a tuning capacitor, which together are tuned to a resonant frequency the same as the radio frequency by adjusting the coil's inductance and the capacitor's capacitance.
Then we show how a radio wave is formed from a microphone's audio wave using amplitude modulation (AM). This then shows how the diode is necessary for converting the radio wave back to an audio wave for use by the earpiece or speaker.
Next we discuss selectivity versus sensitivity and why a separate antenna coil is used.
An finally we show a few other crystal radio circuits.

Discover how a crystal set radio works and some of the hints and tips in building them.
Crystal radios were used in the early days of radio broadcasting. They used crystal detectors that were known as Cat’s Whiskers because of the thin wire that was placed onto the crystal itself. These radios required no batteries, all the power for the earphones coming from the signal that was received.
This video describes how the tuning and selectivity of the crystal radio works. It shows how the tuning capacitor and inductor may be changed to tune in different stations. It then describes the detection of amplitude modulated signals. It shows how a diode detector works. Finally it mentions the transducer and why only headphones are normally suitable for use with crystal radio sets.
The basic principles used within crystal radio sets are also employed in other more sophisticated radios, but this demonstrates how the basic radio principles work.
The video then provides some useful practical hints and tips about building and using crystal radio sets.
