Want to make a radio.

How to make a variable capacitor for crystal radio. Have you ever wondered how a piece of radio gear is able to tune in a particular frequency. You can make all sorts of different types of inductors. Sound powered headphones and how to use them on crystal radios.

What happens when you put an inductor and a capacitor in a circuit. Here is a simple audio amplifier using a tl431 shunt regulator. A crystal radio or crystal set as it is sometimes c.

I made it almost entirely from junk except for the diode 1n34 germanium. Welcome to dave schmarders 78 homemade crystal radio receiver projects with plans and schematic diagrams. All crystal radio plans are shown.

Step by step instructions for making a tunable crystal radio. Build an antique style crystal radio. Crystal radio plans crystal radio circuits crystal radio schematics are all right here.

To tune a radio therefore it is sometimes called a tuning capacitor or tuning condenser or as a variable reactance eg. A variable capacitor is a capacitor whose capacitance may be intentionally and repeatedly changed mechanically or electronically. For impedance matching in antenna tuners.

Crystal radios crystal set crystal sets catswiskers science fair crystal radio and much more. The amplifier will provide room filling volume from an ordinary crystal radio outfitted with a long wire antenna and good ground. In this part im actually going to tell you more than just how to make a crystal radio but im also going to explain how and why they work.

Litz wire is often used. Crystal radio web site. Variable capacitors are often used in lc circuits to set the resonance frequency eg.

First steps in radio resonance and tuning methods part 16. I have for some unknown reason always been interested in ancient technology mainly electronics and mechanical things and i have always wanted to make a true old fashioned style crystal radio. I show very simple crystal sets as well as high performance radios with holy grail parts.

What is an inductor. Something kind of cooland actually important. Theres a lot that goes into making a nice crystal radio set so this is going to have to be broken down into two parts.

This is a radio that gets its power from the radio waves. The first part is the actual making of a functional radio and the second part is making the whole arrangement look nice. Crystal radio audio amplifier.
