Crystal radio technology has been around for many years. This "bottle radio" take on a crystal radio requires no power source, operates on the power from radio waves, and receives signal from a long wire antenna. As radio stations slowly move away from the AM band, the "window of opportunity" to experience this remarkable technology is dwindling. The "crystal" in question is contained inside a germanium diode, and is used to rectify the radio signal so that our ears can hear it.

My grandpa did one in Poland during WWII to listen to London Radio. It was extremely dangerous: if Germans had found the radio, he would have been killed in place.

@fugu08 12 лет назад

Very clear instruction! Now I just have to find the time to make it. Thanks.

@goldenboy5500 10 лет назад

I didn't think that crystal ear phone was still around, the first radio I made was a foxhole radio 55 years ago

@user-ep8rt4nz7e 12 лет назад

Great video! Thank you Weekend Projects.

@loansharky 12 лет назад

You guys did this one already. It's how I found the channel.

@VariablePenguin 12 лет назад

This was a really well done video. Do more like this.

@curghost 12 лет назад

That was awesome, can't wait to try it out. Thanks.

@PhattyMo 12 лет назад

Note: A lot of coat hangers are coated in varnish/enamel of some sort. You may need to sand it off where it contacts the screw,and the coil.

@djguro 12 лет назад

I was making such radios in my childhood.. eh.. there was a time.. :)

@freesk8 12 лет назад

@felixthecrazy 12 лет назад

This is what Make should be about.

@N0SSC 12 лет назад

Woo amateur radio enthusiasts!! I've always loved simple foxhole/cats-whisker's radios, it's amazing how they work.

@adwaitborole99 10 лет назад

@DarkMetalSkies 12 лет назад

great project

@musicalmike235 12 лет назад

I built one of those before but it came in a kit that I bought from radio shack. It actually worked to even though my dad told me it can be hard to get these things to work on the first try.

@Alienalloy 12 лет назад

i've wanted to do this for years...thanks....

@b4blue 12 лет назад

@RevlisGT 12 лет назад

Not a water pipe but w/e. Is there a reason you don't use the crimps on those pliers?

@SATANICDRIFTER 12 лет назад

pretty cool

@MrBenutzrname 12 лет назад

REALLY nice! but it would be even more awesome if you would have explained the physical/electrical processes behind it, cause those are genius! (I know them and I was really amazed^^)

@imranjeffery 12 лет назад

You rock

@miguelpallares91 10 лет назад

Awsome

@bulbinking 12 лет назад

I'm sure you might get questioned by security if you brought this anywhere near an airport.

@cpine522 12 лет назад

I love these! I remember as kid on the bps show "zoom" where they had a demo of one made with two tin cans that fit indie of each other. you would rotate the tow cylinders to change station. I would love to see that on here? Anyone? :) Thanks! Chris

@zachcaskey96 12 лет назад

Great!

@MrJairocool 12 лет назад

woow nice video :D

@Sillyzombie666 12 лет назад

that radioshack mini amp is great for making dyi ipod speakers, only issue is the speaker in it is crap and gets impossible to hear after you turn the volume just a little bit

@paulbergman109 12 лет назад

cool video now i have to make it :)

@Sersoftprod 11 лет назад

@carlinhosff 12 лет назад

Cool!

@michart70 12 лет назад

cool me gusto bien :)

@MrTanyara 12 лет назад

muito legal,ao contrário do que pensam nós brasileiros, tanto estudamos quanto gostamos muito de tecnologia.

@mahela1993 12 лет назад

why can't an earphone use alternating signals?

@salasrcp90 12 лет назад

cool radio

@Malivien 12 лет назад

This is pretty fucking cool!

@MikellHildahl 12 лет назад

You guys made this a little costly. We use to use parts and wire scrounged from old electronics and a oatmeal box (also known as a mush box) instead of a bottle. It would be cheaper to by a store bought kit then buy the materials for yours.

@crazyc4geek 12 лет назад

you guys have already done this project

@1997cram 12 лет назад

nice

@Pwnpuppy 12 лет назад

Cool

@RottenDjaz 12 лет назад

can you tell me how to waterproof a normal battery powerd radio/CD player?

@TheSlyProductions 12 лет назад

I was expecting "...and instead operates only on the power of WIZARDRY!!!"

@HEadshot00001234 12 лет назад

So basically it's like the foxhole radio you uploaded WAAAYYY back when...dam...I remember that hitting my subscribers box and not list!

@Radninja88 12 лет назад

Camera! Shaking! ARRRGGGG!!! Good video though! :D

@DeenSteen 12 лет назад

Cool, I think.

@UnrealVideoDuke 12 лет назад

I thought the bottle would be used in place of a speaker but then I saw that it was a crystal radio.

@gnamp 12 лет назад

which one?

@numex106 12 лет назад

this was actually pretty cool, and WHY THE HELL are you holding my comment for approval?

@iKickItLykeAdidas 12 лет назад

um cool!

@Donflorgon 12 лет назад

I thought I would do this, but I wont!

@1992pattrow 12 лет назад

this is really cool.... just saying

@Hecxa 12 лет назад

Budweiser Bottle Radio for kids

@djnevous3us 12 лет назад

i wanna make 1

@gamerproking117 12 лет назад

this will be great for when the zombie Apocalypse comes

@SinuheSieda 12 лет назад

It looks like so called "fox hole" radio. Too bad it only uses AM (amplitude modulation), cause FM is the fácto in my state.

@SepradistPhantom 12 лет назад

So you're not going to actually demonstrate it?

@AmelsGarage 12 лет назад

Listens to am

@ilikepie2737 12 лет назад

no no no no no no no no.NO......they need to bring kip kay back.

@aksupertiger 12 лет назад

So you know, saying 'You will also need' and then just showing the materials and their names feels awkward. next time, just read them off quickly and let the image sit for a second after you are done reading. Otherwise, very cool video!
