Sir me apka bda fan ho gya

I pod banaiye

Purpose of pyramids and indian temples

[@MrEliasish]

Extremely simple radio, pretty impresed by how simple it is with the frequency tuner. Great invention.

[@xyrokhan]

I used to build those radios 40 years ago using OA71 Diode, the (103pf) capacitor is actually 10000pf, English sub will be good idea

[@robo1989]

40 years only? In India check out praveen mohan channel, this was used 5000 years ago or more

[@LIVE_FOR_TRUTH86]

Oa71 looking very nice i made radio. When my age 6 year

[@samh5535]

What is the purpose of the capacitor? Sorry for my ignorance (beginner here).

[@dapperwolf465]

@@robo19895000 years ago yea stop believing in conspiracy theories it’ll do you a world of good :3

[@AmitBiswas-ib1mn]

5000years ago k insan kaun sa channel sunta tha FM yah kuch aur ???
5000years puran headfone kaisa dikta tha zara batiyeah please.... 😮

[@gettingbuzzywithsreyon2562]

Good video 🙂but some wrong informations!
This crystal radio mainly catches AM broadcast bands mainly and you need less turns for higher frequency (to catch FM)because the inductance is low.
And the output impedance is to high, this can only drive crystal earphones without any power, not 'regular headphones'. To drive 'regular headphones' you need to connect FET transistor instead of germanium diode.

[@mauriciobastospy2tad]

I also really like this content, congratulations on the channel! I have several videos of electronic circuits, mainly of homemade radios (homemade) where I make available the schemes and often the layouts of the PCB. Hug from Brazil!

[@INFOTRONICX]

How many turns in secondary and primary diamenting of coil wounding menterial!!!

[@user-eu3cv9lb2l]

Ap se bahut hi sikh ne ka milta he thank you sr

[@hassanrasool3977]

You vary vary good cantanyo
أنت جيد جدا استمر القادر يوفقك

[@techelectrohub8546]

Sir Explain how the variable capacitor in the radio works. For tunning

[@nursingclasses2023]

Super sir ..i likes your all video

[@TechnicalidEas07]

#Mst🧡🔥

[@medico_ansary]

Great invention

[@krishnakarmarkar9354]

How much turn are you give on the secondary and primary coil
Reply me please

[@camrynhunter6969]

Love your channel bro.

[@crazyrajuofficial]

Tq u sir is video ko banane ke liye

[@titanicstech1064]

Please use thin tunning rod for fine tunning

[@parthgupta381]

Can you please tell why we are using diode in it and what are the no .of turns in each coil

[@randommosaic7080]

Diode is used to convert the full wave ac to rippling dc and capacitor is used for smoothing it

[@karthikr3044]

Nice video, basically it's an old crystal radio set. Its not 103pF capacitor it's a 10nF capacitor. This circuit only works for AM radio waves .

[@Am_Photography13709]

thanks for the info but i am able to use it with my 16mhz audio transmitter so it also work with mw radio

[@navidfarhan3775]

But crystal radio works with only Crystal earphones and a huge anteena is needed

[@pravanjantripathy7345]

Sir can you help me make a control circuit . which is operated by mobile and it starts fist to inform by measege power ready, over load , circuit healthy condition and good condition of starter ready for start to water pump.

[@shaikzabu1168]

Very good 👍

[@ishwarnarayan2411]

Sir ji ismay kitnay turns laganay hai primary or secondary coils may please batadijiyay

[@oo-rx1we]

Big fan sir ji..#respect

[@cheraking1912]

very very good

[@bishwajitbaishya1346]

Aapka bahut shukriya sir please ap our Aisa video banay

[@palakjain4182]

Can i use another diode at radio where we want to put ground

[@dz-abouttechnique1849]

Super!

[@Psandroidinfo]

Vai you are a genius bro

[@prav5554]

It is a "somewhat" fm tuner, with no filtering unit. Nor any amplifier. Hence so much noise.
But great attempt. Keep posting. So much to learn from you.

[@Gopalnandi24]

Nice👍

[@arvindmishra859]

Mast bhai

[@sanjeevkohli6270]

Nice vedio sir.esi trah se 1.5v ya 3v fm bana kar dikhaiye.plz sir.

[@tayyabali6481]

Amazing

[@CircuitCreator]

The way this video highlights the innovative features of this device is truly impressive.

[@SurajChauhan-cy1ny]

Really.... A century old tech you are showing here.
This type of radio was popular in 1920.

[@shubhamshekharrai94]

there are two dedicated plates in earphone for VCC and GND it wont work without external power and power recieved from elemagnetic waves are very low then how it will work?

[@mmallick3224]

He just made a good look using the regular earphones. One needs an amplifier to listen such low signal.

[@deepanshukumar6591]

Jo MP 3 ka mana sinhnal kasa acha kara please batay Bhai FM ki audio ko acha kara

[@satishpradhan143]

👌👌👌👍
Bachpan me science project book me dekha tha or banaya bhi Par chala ni... par Ab chal jayega

[@satishpradhan143]

Us time pata b ni tha diode, capacitor kya h...

[@abhaydeo2373]

Sir I will support you

@Icy he is just asking coz he want to learn that

[@JaspalSingh-bg3fo]

Ram ke ram kaho. Ji sir bahut badia mini radio apne banaya hai .wow thanks sir

[@kanjitramchiary7183]

Sir is it possible to catch signal without crystal head phones, By the way what are you making should be Cristal radio which was used during the world war 2 after foxhole radios if I'm not wrong.

[@ashishkavathekar6703]

Kitni frequency genrate hoti hain..

[@ahmarsaeed6085]

So the Primary and Secondary coils are not connected?

[@somnathkundekar2790]

[@TarunYadav-dp1id]

Can you explain in very very detail of how its working on board or on blank copy. I would love to

[@ganeshbhuiya6957]

Thumbnail very nice

[@MrMinimum24]

Sir headphone nahi chalenga use crystal earpiece(piezo buzzer) for better voice

[@podiesttisanjay9182]

Sir there no video about induction spark coils old help me

[@anshulsaini7440]

Can we play it on any frequency
For example
12647 H of Sony sab

[@ElectroShotGROUP]

Good project but why here is so much noise when I made it my self i do not have noise like that. I use hi gain amplifier.

[@shreyashsingh2556]

Can we use 104 pf capiciter

[@amithansda1863]

Sir aapne 555ic se inverter banaya tha uska gurber file de dijiye

[@dineshsikdar7954]

Fm transmitter kaise banaye? agar iski ek video banaye to hame bohot khusi hogi or jankari bhi, thanks

[@harisfernandez5375]

Number of turns for primary coil and secondary coil, was not mentioned in the video. Can you please give the number of counts or turns, for that coil.

[@manindersingh8130]

Primary coil 25 turns and 2nd coil 90 turns

[@TechsScience]

Nice!
We are living in the Computer age still most of us even don't know how the radio used to work

[@veeruparashr128]

Ye jo almoniam Hai Kya iske badle loha use Kar Sakte Hai

[@mannalal3831]

I had made this of Radio in 65 year ago by using simply Soona Makhi Stone Antena and Aireal only

[@kparts1905]

Jo 103pf capacitor hai ye tho bhut jada high capacitor hai es ke jagah koi or jese nhi kr skte hai kya agar nhi hai ye vala tho

[@niladritheboss]

Kanti sir agr fm gang use kiye to kay higa..??

[@mtalhakhalid1679]

awosm this radio was used in world war 1 and 2

[@sp.electronic415]

In4007 diode nhi chlega kya

[@teluguyoutuberkarthik_elec9020]

Hi sir can i use 28awg wire for this project

[@tonywright8294]

No it’s against the law !

[@IT-wv1ey]

bhai aap inn project ke bare me jankari ya data kanha se lete ho . inn project ka source kya hain jnha se aap ko knowledge milta hain inhe banane ka

[@syedhassnainali2917]

Thank you

[@japhetskytze383]

I could not find the circuit, could someone help me?

[@56sankhodeepmitra45]

Sir this is an AM envelope detector

[@harshnarayan1969]

Shreemaanji primary or secondary coils may kitna turns lagana hai yeah samajh may nahi aaya please banadijiyeah.🙏

[@Art_N_Design]

Sir !Ak Thermal night vision nanaeea please

[@gautamaditya7801]

Kanti bhai normal diode se hoga kya?

[@nazrulhuda4767]

Sir, dc,to,dc booster circuit diagram denge high waat amper ka,

[@user-xd7kc8jh8b]

Bro it work bro work

[@v.k.ssenapati8082]

Very good project.
But output sound is very noise

[@chinmaypal8667]

Ek cristal diode laga dijiye. Sound jada clear hoga

[@aicreation602]

Bhai ye radio tumhe hi mubarak ho , jiske paas ghar me kaam na ho wo apna keemti faltu time isme waste kar skte hai dhanyawad

[@teja9676]

Excellent brother

[@adarshpratik5917]

Can we use toy motor winding
