Making ' crystal Radios ' is a hobby I mine .... so it's time to make another one or two.
It can consume a lot of time to get the ' coils wound and making sure detectors are correct values....etc.
These don't run on electricity or Batteries.... just use a ' long wire ' antenna and a good ' grounding ' earth .... and use a pair of ' High Impedance Head Phones ~ 2000 to 3000 ohms.
