• Listen to the radio using the power in the radio waves
• Simple and easy to solder with six parts
• Requires no batteriesWhat can I do with this kit?
Use this crystal radio kit to listen to radio without needing any batteries. Crystal radios are one of the oldest and simplest types of radio receiver. Widely used in the early days of radio, they were eventually replaced by amplifying radios which used addition power in the form of batteries or mains to amplify the signal. This is a great circuit for those just getting started in electronics and those who are interested in radio.
How does this kit work?
Crystal radios are the simplest type of radio to power, as they get all of their power from the radio waves themselves and convert it straight into sound. Everything you need is included to make a working radio. Capture a signal with your antenna, then use a rod going through a wire coil to change the frequencies you are tuned into. Earth yourself by attaching the wire to a bare metal item such as a radiator. As you build, practice your soldering by attaching the diode, capacitor and earpiece. This kit requires a soldering iron, solder and wire cutters/strippers.
How easy is it to assemble this kit?
This is an ideal kit for a beginner, with some components requiring soldering and others needing to be to be manipulated into shape. With no power supply required and all the components included, you can have plenty of fun creating a working radio. When you’ve assembled your kit you can make an enclosure for it or experiment with different lengths of antenna and coils to see what a difference it makes.
