crystal radio

[@chronobot2001]

Wow, it's a work of art. It looks like something HG Wells would have dreamed up.

[@SaintSkyler]

This is the most beautiful radio i've ever seen.

[@JohnSmith-eo5sp]

If you like a mongrelization of steampunk Edwardian Era technology combined with modern microchips made in China

[@videshx818]

So elegant looking crystal radio, wow !!!

[@karob6569]

What you point to in the photo is not a Marconi receiver - that was his induction coil transmitter. The 'balls' are the spark gap resonators.

[@Mikesorrento3344]

Now that qualifies as a bonafide contraption.

[@richardparkersmith4810]

Wow! What a set. More adjustments than I have seen before and never ever seen ground amplifier or the balls column. How about publishing a wiring diagram?

[@brianbaird4573]

I am assuming there is a battery for his amplifier, but the rest of it runs on radio energy harvested from the antenna. Now, I wonder if some of the modern low energy integrated circuit "energy harvesters" may be able to charge the battery while the radio is not being used, by storing the energy that would normally go to the speaker. Pair that up with a modern super efficient digital audio amplifier IC and you will not need batteries unless you plan on listening A LOT.

How do the copper coil structure work as a ground without connecting it to earth?

[@franzliszt3195]

So the copper coil thing is a ground?

[@романроман-щ4п]

Браво мастеру! Это шедевр!

[@maikerumine]

What a nice build!

[@centralna.poczta4648]

Super radio...pozdrawiam z Polski

[@niunaixin]

2:05 what is the copper screw thing that kent uses to hook up the antenna wire to the radio with? what is the technical term for it?

[@JohnSmith-eo5sp]

5:00 He calls it the "Ground Plane" that "intensifies the Ground Force" - - doesn't make sense to me either

[@endadalton]

What an amazing radio, truly fantastic.

[@RobinsonDanieldosSantos]

Hey! That's absolutely fantastic!

[@mahmudrasheed3045]

Amazing 🙏..thanks from Iraq at middle east

[@ronalddaub7965]

That is something thanks for showing it I have a crystal set made from one at Water Kent capacitor and tapped coil.. they're also interesting.

[@jimdawes7261]

Talk about "resto-mod", wow!! Beautiful construction.

[@bassamali7738]

Is there any power supply in this system?

[@baikushex0et682]

No But he has an audio amplifier Which requires power

[@markforeman3101]

What powers the radio

[@michaeloleary1867]

Awesome radio!

[@steelcantuna]

Very beautiful old timey looking! Does this NOT use a battery????

[@kennynvake4hve584]

The radio doesn't need power, but the LM386 amplifier would have to...

[@mtkoslowski]

Kennynva : correct. I was scratching my head over this. Pure crystal radios use electricity, as you know, from the antenna. Pretty set, but...smh

[@ronalddaub7965]

No battery... Some people add amps . But A regular crystal radio doesn't

[@pedromolin6941]

Fantastico!! Beauty...superinstrucctivo ...full quality and artesanal...wonderfull. I want this radio!!

[@Hangar77]

Cool, thanks for sharing!

[@mr1enrollment]

Intensify the ground? What BS.

[@baikushex0et682]

Looks.pretty

[@JohnSmith-eo5sp]

0:41 Oh that is kind of cheating isn't it? A True Crystal Set is a passive receiver! But if you need an audio pre-amp then you could have acquired an excellent one for such purposes from Radio Shack! It too was built around the LM386, and came with its own RCA connector cable. I don't know if they are still being produced, but no doubt it has a replacement model made in China

[@baikushex0et682]

Well he has headphones But if he wants to demonstrate it It needs an audio amp.

[@ronalddaub7965]

You can use all that stuff without all the IC chips he just went all out
