A VERY Basic One Component Crystal Radio

- I discovered a pamphlet that tells you how to create a crystal radio with nothing more than a detector, headphones, antenna and ground. Will it work? Let's just say we gave it a try! In this short video we will discuss crystal radio operation, set up a one component crystal radio, and then add some tuning capability to see if we can pull in more stations.

I very much enjoyed today's video. I think this is a great idea making thease shorts. As usual very well presented. Could you please at some point in the future show us how to construct that lovely MW antenna you were using. Thank you.
Yea, really effective! :) I live in Houston TX where there are a lot of strong stations. The result of this experiment is a jumble of stations all blabbing away on top of each other!
That was just another great video. THANKS
Awesome, love the "Snippets"
Inductive Amplifier that is new to me I learn something new today thanks !
Neat.
Glad I found your channel.
I may give this a go if I have a 1n34a, but even a low voltage biased silicone diode should work according to Gasslinger's experiments.
I am aiming to build a direct conversion receiver, but a crystal rig might be a fun warm up.
excellent demo & explanation, I love anything about crystal sets..but I got you beat...while experimenting with a crystal set, I connected an old CB antenna to the hot side of the mic input on a laptop-when I monitored the mic input using VLC media player, I heard my local MW station loud & clear (no diode, no ground, just a single conductor antenna). This was accidental & I'm not sure but I'm thinking the mic input has some sort of diode protection that's demodulating the signal, & if so, technically the laptop is replacing the detector, headphones, and ground.
That wouldn't surprise me. There are documented cases of people receiving stations with fillings in their teeth. The body acts as an antenna, one filling acts as a detector, and another loose filling or bridgework would vibrate allowing the person to detect and hear a radio broadcast.
Imp. Question-sir, to add the metal/gang capacitor in this crystal radio, do one needs to make that loop/spiderweb antenna or a horizontal antenna?
Similar design antenna like that of yours, you are using both ends of the antenna, one to ground n earphone, n other ebd to gang caps. Does the ground end of the antenna needs to connect to the earphone too?
I would love to know how to make this antenna, is it possible? At least at least have the plan with the wire length details. Thank you very much, very nice video that I share with my friends.
What is the type n value of the capacitor 1 in your first diagram? Is it a polystyrene or ceramic one?
