All Band Radio Receiver

[zacdee316]

"the radio receiver must be built on a breadboard because I could never get it to work when building it on a circuit board or similar."

Did you ever think that maybe your just better at breadboarding than actual circuit construction? I'm almost the opposite. Almost anything (except very simple circuits) don't work on the breadboard for me but on perf board it works beautifully.

[jrcstudios]

Listen to compact florescent lamps.. different models look exactly the same but sound different.

[hubzcaps]

dude you kick ass you make your own circuts

[chairdude1]

I love makin shit like that,tech stuff begs to be messed with..

[lionheart270866]

this is kinda like one of those guys that got fired from NASA and builds things to get revenge

[coondogtheman1234]

I have several devices that use the LM386 amp IC, one is that toy megaphone that I hacked and I have others. it is pretty powerful if you give it power. im surprised that such a small IC can drive that big speaker.

[Ragrog105]

Hold any IR remote up to the antenna wire and press any button. You should hear the IR code chirping and clicking. That's a little known method of testing them. Radio Shack wants you to but an Infra-red card and that costs a few dollars. Any AM radio tuned off station will work too.

[coondogtheman1234]

I actually have that IR detector card and yes IT SUCKS. ill just use a radio set to AM mode. works even better

[FelixTheHouseFreak]

Cool you like to fuck around with this stuff just like me! hah

Do you have a schematic?

[CassetteMaster]

I have a schematic for the radio part somewhere, and the 386 amp schematic came from somewhere. I built that part a while back.

[triforcehyrule]

@CassetteMaster can you give the schematic?

[dadburnde]

I dont really see the point of and all band receiver since you would probably not be able to tell what the heck you are receiving and technical think its impossible.

but I still think its a great Idea

[adeshization]

wha...

[Probewitch]

How very retro, looks like fun.

[Kcy101]

Nice Radio man, Take it its am? possibly also ssb?

[itakeyourphoto]

Mate with a mind like that you should become a Ham.........Then again maybe you already are... You remind me of some that I know......hehehehe

[AllanPoyhonen]

BTW: Whats the name of the song in the end of the video, I want to DL it.

[CassetteMaster]

"White Room" by Cream.

[AllanPoyhonen]

oh yeah, that is a really cool radioreceiver!

[SamuraiClinton]

This is ridiculous! :-P

[jefferyb304]

Nice house. Like the project.

[audiotrash47]

So it doesnt tune? it picks up everything at once?

Anyway awesome, also the song at the end sounds good, sounds familiar.

My own attempts at building lm386 amplifiers havent always gone well XD.

[audiotrash47]

Oh hang on the Dj introduces it LOL stupid me, Cream, thought so.

[itscool1968]

ricky its not good to run a mirowave empty you can distory the meganatron.

[raymondleeleggs]

How can that destroy the magnetron?

[robatsea2008]

good work!

[AllAmericanFiveRadio]

NSA is going to knocking on your door!

[raymondleeleggs]

LOL

[CassetteMaster]

What is the NSA?

[coondogtheman1234]

national security agency you ever watch the movie Enemy of the state

[AllAmericanFiveRadio]

National Security Agency

These people listen to everything!

[damusician]

u mean they can detect that device he has?

[AllAmericanFiveRadio]

LOL! They are all knowing.

[Kcy101]

Nope, Its impossible for them to detect any receiving equipment, Usley ppl are cought by braging about what they do ur giving out info to a source .

[sparkdetect]

Actually, receivers with oscillator sections in them can be detected. They generate carriers. As you tune such a radio, the frequency of its generated carrier changes. To demonstrate this, bring two superhet AM radios near each other, and by tuning one across the band at some point you'll hear a whistle or "swoosh" on the second set.

[spatsbear1]

Neat!

[ddl312]

wow, how cool

[lmull3]

nice, dude! makes a great EMF detector

[coolbluelights]

Awesome!! I built one like that from a radio shack kit. where'd you get the scematic and everything?

[CassetteMaster]

The radio section is from a site I believe called Techlib.
