How to make a 3D printed AM radio!

[@KeystoneScience]

Hey, if you guys have any suggestions for fun experiments let me know here! ( i have a fun experiment planned for next time there is a thunderstorm near me, so look forward to that ;) )

[@Nate.mp4]

Do some arduino projects!

[@celifreo6586]

Yessssssss! Make a nuclear fusor please, and make a custom mirror! If you don't know what I'm talking about, try looking up homeade nuclear fusor, basically the high voltage vaporizes aluminum, than sticks to a Piece of glass, creating a mirror. It's really cool :)

[@celifreo6586]

Also great job getting on the jlcpcb bus! The other two websites are Lcsc.com and easyeda.com :)

[@daveshakibanasab7992]

I don’t think that’s how the osscilation works. The inductor discharges in the same direction and charges the capacitor to the opposite polarity. Then the capacitor discharges in the opposite direction.

[@data_phile3923]

Keystone Science I've been wanting to make my own CNC water jet cutter for sheet metal, however I have not found any good videos on the subject on KZbin. More specifically focusing on the pump and jet the CNC part is abundant on the web lol :p

[@3DSage]

Thank you again for making my 3D printed radio! I just watched this video again and really enjoyed it! I hope to see more of your fun projects soon.

[@DanielBerzinskas]

This comment, and your videos deserve a lot more likes!

[@3DSage]

@@DanielBerzinskas Thank you for saying that :)

[@DanielBerzinskas]

@@3DSage I'm trying your radio soon once I get my function generator assembled (coming from China to NC)

[@DanielBerzinskas]

@@3DSage When I get it working, I'll make a video with a shoutout to you

[@3DSage]

@@DanielBerzinskas That's great! Send me a link and I'll share your post.

[@DrakkarCalethiel]

really didn't expect that a fucking selfwound adjustable inductor and a diode are enough to build a somewhat functional​ AM radio. Shows that often you just need to be creative to get something to work. Great vidjeo!

[@nbraynor]

Its actually not that difficult. I've picked up radio stations on an electric guitar before.

[@kedarprabhudessai]

U need to be close to transmitter enough so as to absorb this energy andbproduce sound otherwise u will need amplifier

[@pufango4059]

Why did you need to swear ?

[@w8lvradio]

I have experimented with radio for over fifty years, and hold every Commercial and Amateur Radio license. Really. All of them. This in No Way means that I am "smart"... THAT being said, what it DOES mean is that I have seen (I should say suffered through!) MANY a presentation on Radio Theory. Which is usually done, badly. Very badly. And when NOT done correctly, that's pretty much "it" for most people, and they miss out on EVERY successive step in the learning process, which is just sad. Setting equations aside, an almost impossible task, GIVEN the task, that is the BEST explanation of LC Resonance/AM transmission for the newcomer that I have ever had the pleasure to see. You've done all that, and made it entertaining! Well Done, Sir! 73 and All the Best, William Pietschman (W8LV)

[@Felecc]

Nice moustache you have there, like a real scientist :D

[@georgevavouras]

I just now noticed that music plays while you talk in your videos.😂😂

[@stonecold7945]

George Vavouras lol

[@danielmueller8974]

Thank you so much for mentioning my channel! As of late, I received another grant from a local university which I will be using on camera and microphone equipment! Great video as always!

[@KeystoneScience]

Thanks so much! Also, glad to hear!! I’ll send you an email tomorrow!

[@danielmueller8974]

I just talked about what I am hoping to do on KZbin and at my offices and said it would be awesome if we could chat. I am not a stalker XD Don't worry

[@mazkaiventas8240]

You are a ledgend man, no need for the expensive stuff! Just keep doing good work and those who are here to learn will stay! Much love! Be safe bro

[@science0074]

Please wire up and test the Tesla Coil

[@bloodsweatandtearsforeverl9833]

This is the basics of a Tesla coil, it's like karate kid, you'll understand sooner or later

[@dhivan]

Love the video!! I had a crystal radio kit when I like 10 and never knew how it worked but now I know!!

[@erikpratama320]

Can i add some booster receiver and amplifier on it? I wanna try it but finding those diode seems impossible here

[@pyromen321]

I was confused when the right-ear channel cut out

[@KeystoneScience]

Me too, I have no idea what triggered it

[@platput]

I really like your videos and how you explain stuff. I think it would be awesome if you start a series covering the basics of electronics with its practical applications. Not like you would learn in school.

[@WildfoxFabrication]

I can tell you used Cura to slice those models... am I right?

[@KeystoneScience]

Yep!

[@WildfoxFabrication]

I can tell because of the top and bottom layers are "spiraled" instead of a zigzag, which I personally prefer. You can change that by clicking on the little gear in the top right of the "shell" section (if you slice using custom mode) and change it from "concentric" to "zigzag". this will make your models more flat and tolerant. BTW I have a tevo tornado too :)

[@erikpratama320]

Hey,can i just use an speaker coil for this purpose?

[@dhivan]

Is the reason that you use a germainum diode because the voltage is below 0.7v?

[@InlikeMikeQuinn]

Great info!

[@Sultan-mu6on]

is there a specific number of copper rolls

[@boggless2771]

Can you make a battery or supercapacitor?

[@Web3Dre]

Why would you use a zener diode and not a germanium diode in a crystal radio?

[@KeystoneScience]

It is a germanium, it does look like a zener though

[@NotLegato]

super interesting. can you make one for FM radio? i've always wondered how that works, since the antenna shouldn't be able to remain the same length for the propagation of waves.

[@cesarin159x]

Where the vids at man?

[@evilchickenman6446]

This is so cool, I learn so much from these vids :)

[@Artemis-zl5cs]

You should sell these as kits online with all the materials and a full set of instructions(or point them to this video)!!

[@loganathanvb6834]

Can you make a tutorial on joule thief circuit

[@DevPatel-nf5mp]

Pls upload videos regularly ...U inspire me

[@JordanPool13]

Is the Germanium diode absolutely necessary or could I use a Schottky diode?

[@pufango4059]

No it wouldn’t work . A germanium transistor can be used If you don’t have a germanium diode,just connect the base and emitter .

[@ChozoSR388]

I remember building a crystal radio kit when I was a kid :D

[@pufango4059]

Why did you tell us this ?

[@ShobhitVashistha]

Whats the update on reactor with cody? waiting for that to come out :)

[@Hexalyse]

Reading that 2 years later, I am sad to know that KZbin basically killed such projects with their insane rules... It would be a sure way to get your channel demonetized or taken down.

[@caedmonfoore1780]

Could you show your TESLA COIL if you fix it.

[@NoviSavvy]

How about your reactor?

[@luongmaihunggia]

The concept is very well explained in a simple and easy to understand way, liked! Suggestion: 50000W 12V DC to 220V AC inverter? Most houses consume this much power (my math might be off) and there're no inverter powerful enough to power a house. Or a 50000W DC to DC regulartor (stable constant output voltage) for a solar panels system. Or a power meter that can measure atleast 50000W

[@baqcasanke]

redstone craft guy dude a 12v inverter for 50,000watts would need 4,166 amps!!! Which would require cable as thick as your body. Also houses do NOT use 50,000wats you don't get it. They may use 50,000watt/HOURS per day but def not 50,000watts of power,

[@seanstutsman1935]

Well hello!! In love with your content 😊

[@TheRadiogeek]

Cool 3D printed crystal radio. Nice design.

[@baqcasanke]

TheRadiogeek its not a crystal radio

[@TheRadiogeek]

Baqca Sanke yes it is. It has a germanium diode in place of a chunk of germanium crystal.

[@lightningpower4599]

Do you know how to program an arduino uno?

[@FirstLast-kv1iq]

Where have you been? I miss your content

[@KeystoneScience]

Awe thank you, I’ll be back soon, I just had a lot come up at once, but I started filming again on Saturday, so I should be able to get a video out Thursday, and hopefully weekly again from there on out

[@FirstLast-kv1iq]

Thanks for the update, You make awesome content and I hope to see more of you!! PS I am really excited to see the colab between you and cody, hope to see more updates soon

[@somerandomcuberyt3384]

I got wire of a transformer is that magnetic wire??

[@matthewlallinger9603]

Yes.

[@jimsmindonline]

Razor blade "cat's whisker" diode upgrade!

[@HeatmanMKIII]

Wait, i didnt get the part of how its powered

[@SadamFlu]

what a brilliant explanation and demonstration! this seems far simpler than the crystal set radios I made as a child. how does this one work without being grounded to the earth?

[@Jimwill01]

He took a short-cut, but he told us about it. The radio was grounded through the amplifier.

[@SadamFlu]

the crystal set radio I constructed as a child used the same piezoelectric ear piece setup as he did, but I also had to ground the whole circuit to earth using a rod stuck in the dirt...

[@itsmarv3982]

keystone scienc pleas make a vidwo wher you make 240v out of 9 vlot batteris and you plug them together thx cool video

[@andystevenson4305]

HELP! i thought radio waves were photons. Why is the transmitter making a magnetic field at the antenna, and how does this make photons. Also how does the antenna turn the photons into a magnetic field

[@buildersmark]

Sporting the 'stach. Good video.

[@tek4]

Dont shave, cause its your body, screw the haters

[@stonecold7945]

tek413 All cool scientist have mustaches

[@salifford]

agreed

[@bloodsweatandtearsforeverl9833]

I think outside of the box- if it's "lenz's law" would the "signal" be amplified if you put it through a "lense", my theory that this will work is that Nikola Tesla said that everything is a wave, light,sound

[@burntoutelectronics]

Aah the old crystal set

[@baqcasanke]

Lets Shoot Expired not a crystal radio

[@manchee5543]

Do you have to 3d print it

[@luongmaihunggia]

No, you don't have to 3d print it.

[@dryaldibread2327]

PugLord you dont really need one. A wooden or paper frame is enough.

[@jeavalos]

That awkward moment while reading the letter sent to you was hilarious. The face you made made it pretty obvious. Looks like your gonna need to use another part of your wall for more awkward letters. Great video!

[@victorbergersen]

here in norway the am band has been shut down years ago, now the fm band is closed too

[@Anticorriente]

O men, you have mustache now!

[@DevPatel-nf5mp]

Ur audio at last part of video is horribly one sided

[@Sprengstoff83]

looking like a young einstein with this beard and hair combi :D

[@burntoutelectronics]

I would imagine connecting an amp to the radio would pull down the frequency of the set considerably and to much of a load and it woild stop resonating. Net time you should use a real cat wisker

[@hellhoud2825]

a truly american facial hair :')

[@whatitis5646]

Did he just teach us how to make our on radio station?

[@KRAFTWERK2K6]

Interesting. Not even a variable capacitor was incorporated. That would have made it easier to fine-tune it. Also… aluminium foil? Come on ;) Anyway, really appreciated this neat and tidy design.

[@gtesteve9434]

u are amazing make a free energy generator

Please make a video on how to make telescope at home please please help me I am from India. I have subscribed your channel I see your videos without fail.

[@MrItchyStitch]

Do you even listen to your videos after they're uploaded? Damn you speak so fast it looks like it's 2x speed. One can get easily lost if we don't pay extreme attention, what is a shame because the content is great.

[@KeystoneScience]

Yes I listen to them. I suppose since I already know it, I don’t stop to think how fast I am going. My older videos were a lot faster, so I have tried to make some conscious effort to slower speaking. I will try again.

[@MrItchyStitch]

Thank you to spend the time to answer to my comment. Keep up the good work!

[@HighFidelityFox]

If anyone wants this 3d printed, email me and I can make all the parts for $15

huh, 70th view, why upload at 5 am?

[@RDavengerr]

its 4 pm in india
