Crystal Set – Radio that needs no Batteries

at 2:55 pm. Filed under DIY Hacks, Electronic Hacks

Richard Sudney (Youtube user 2sudsy) has been building Crystal Sets since he was 9 years old. He is a bit older than that now and his passion hasn’t drifted, it has just been honed over the years.

“A crystal radio receiver, also called a crystal set, is a very simple radio receiver, popular in the early days of radio. It needs no battery or power source and runs on the power received from radio waves by a long wire antenna. It gets its name from its most important component, known as a crystal detector, originally made with a piece of crystalline mineral such as galena. This component is now called a diode.”

    Impressive work. I was kind of hoping for a demonstration on the video. But I guess I’ll have to go dig one up myself.

    Here’s a list of fun and unusual things I have demonstrated with a basic crystal radio circuit…

    1.) Hook it up to a computer and use software to radically increase gain.
    2.) Listen to local storms and lightning. (Don’t use a long outside antenna!!)
    3.) Create spooky sound effects with sound software pitch control.
    4.) “Read” colours on the computer screen with an unpowered crystal radio !
    5.) Make the crystal radio respond to a moving screen-saver image.
    6.) Use the crystal radio as a microphone.
    7.) Sense light of all different types and frequencies with the unpowered radio circuit!
    8.) Much more 😉

    These demos are shown in my Crystal Quantum Radio playlist at http://www.youtube.com/user/MrfixitRick#grid/user/AFEC01FF72B51D45

    That’s a lot of wire for a wireless received 🙂
    Excellent work by the way, love it!
