Perhaps the simplest radio one can build is the crystal radio. Using a diode as a detector, the design generally uses less than 10 components and no battery, getting its power to run from the radio ...

A staple of starting off in electronics ion years past was the crystal set radio, an extremely simple AM radio receiver with little more than a tuned circuit and a point contact diode as its ...

If you are ready to take a break from high-speed, complex digital systems, consider becoming a “rock hound” and constructing a crystal radio, one of the earliest forms of receivers. For close to 100 ...

This fun little DIY device is labeled as a “crystal radio circuit in a jam-jar.” But that description doesn’t even to begin to do it justice. According to Tesla, this electronic wonder allows you to ...

The possibility of producing FM crystal radio is shown in this project which can produce a sound with high fidelity that is as good as or better than more expensive AM radios when connected as a ...

Tesla’s Spirit Radio uses a simple crystal radio circuit connected to a computer sound-in jack to generate spooky sounds from all kinds of electromagnetic sources. As you will see, it creeped the hell ...
