⚠ God has said in the Quran:
🔵 { O mankind, worship your Lord, who created you and those before you, that you may become righteous - ( 2:21 )
🔴 [He] who made for you the earth a bed [spread out] and the sky a ceiling and sent down from the sky, rain and brought forth thereby fruits as provision for you. So do not attribute to Allah equals while you know [that there is nothing similar to Him]. ( 2:22 )
🔵 And if you are in doubt about what We have sent down upon Our Servant [Muhammad], then produce a surah the like thereof and call upon your witnesses other than Allah, if you should be truthful. ( 2:23 )
🔴 But if you do not - and you will never be able to - then fear the Fire, whose fuel is men and stones, prepared for the disbelievers.( 2:24 )
🔵 And give good tidings to those who believe and do righteous deeds that they will have gardens [in Paradise] beneath which rivers flow. Whenever they are provided with a provision of fruit therefrom, they will say, "This is what we were provided with before." And it is given to them in likeness. And they will have therein purified spouses, and they will abide therein eternally. ( 2:25 )

Cómo lo podré hacer, si no se en qué dirección se instalarán esas resistencias, además no se qué significan esas franjas de colores y dónde conseguir esa placa para soldar esos componentes. 😂😂😂😂😂😂
Tenes que estudiar electronica
How to wind the antenna, approximately how many turns?
Great video. I am an old engineer from the 50's and I like that youth love radios. Cheers from Patagonia Argentina

Tengo 17 y escucho la radio,me encanta ya que tiene un no se que y es hermoso pasar una tarde escuchando radio.
In 1957, in Los Angeles public school, we learned about the crystal radio and how to make one in Third Grade.
That started my career in electronics as an Electronics Design Engineer.
That's amazing how a simple lesson in second grade sparked your career in electronics! It just goes to show the power of early education and how it can shape our future.
Yes it ruined my life too... :)
I have seen so many people making boards, but this is the best. I wish you could do the project on a breadboard. Thanks a lot. Nice video
Muy buen video, yo una ves hice una radio así y funcionó exelente...tu vídeo está muy bien explicado...saludos!!
Excelente video. El punto crucial del circuito, es el capacitor variable y la numeración de sus pines. Ya casi, no los están fabricando.
Wow! I learned two things from watching your video for only a minute. A new way to use SMT components.
thanks for your comment
Great🙂 Very simple. Thanks
Dulu waktu sekolah praktek sendiri .hasil nya bagus ..jadi teringat
Excellent video! 👍
I love radios , thank you very much.
This must be everyone's first electonics project.
How I miss when Inhad time for this! 😪
I hope you really enjoyed watching the video
Lets do it this time
@@inventorkr1 very much!
Did that when I was 12 yrs old. Also made one where I could tweak the coils and pick up short wave. Foxhole radios from WW2 were simply amazing using a razor blade and a few spare radio parts.
Nossa que top parabéns gostei muito
Interesting. Nice project.
Meu sonho é um ferro de solda mágico, desses dos vídeos do TH-cam, que soldam componentes em um segundo!
O meu tbm 😅
Pls clean the soldering iron tip every time when making new joint. And bend the ends of the componemts pins to make more contact surface, like in SMD part.
This will significantly increase the quality.
Thanks for adding this tip
Agreed!
Que bueno 😮 saludos desde Bolivia
Awesome you just reminded me i have to go get some peroxide
You are great human! Thank you for detailed s-b-s construction, you inspired me and I am sure many people who watched! Great job! Great author, thank you for educational and working practical video
Sub ❤
thank you
Bravo , complimenti !......Si potrebbe migliorare nel calcolo differenziale delle resistenze.
This was pretty cool!

Hello good friend, you have a good idea. you are very good at electronics, your video is very good, thank you for sharing ❤❤❤
If he was that good at electronics, he would still holes into the circuit board and fit the components properly and teach genuine construction methods!
Всё бы хорошо на А М сейчас не работает только фм , жалко диапазон 😥
Parabéns pelo vídeo..vou montar um se der certo volto aqui pra dizer o que ouve.
Thanks from India
Teringat jaman sma th 1982 buat radio kek gini😂
Labelling the TA7642 as a JFET is completely misleading. That's an entire AM decoding circuit in a three terminal device, not a simple transistor. Also, good luck trying to find variable capacitors that are the right size these days. They are very hard to come across.
To people watching this -- if you want to build an actual AM radio from a kit, I highly recommend the Elenco AM-550CK. You'll learn a lot more, and end up with a great AM radio for the AM broadcast band.
I built this but the only thing I heard was the load snoring of my neighbor.
Значит был неучем в школе и спаял все по женскому половому органу🤷♂️
Precisely. I ordered 10 pcs of TA7642 from Ali Express and they came out to be all fake.
😂
LOL 🤣😂
dang u reserveed a sleep monitor 😂❤
I like these PCBs that don't have holes. So much easier and quicker to make!
Yeah, only problem is they look like an unprofessional POS. Also, look how dirty his soldering tip is. Clearly has no idea what he's doing.
The ferrite inductor actually used is certainly many times stronger than the little coil in the display image. With that little coil the tuning range would be perhaps in the vhf spectrum.
Wrong. What do you mean "display image" if you care to look at the data sheet, the ferrite aerial concurs with the datasheet guidance.
Next: make one without a power source
Radio works fine, but there are interference sources in the area that make the radio stand out(work less well)
They can use straw sources: TL lighting or switched-mode power supplies and telephone chargers
Very nice👍👍👍
SUPER 😮
Thanks good channel ❤
Спасибо!!👏👏👏👏
En los radios AM la recepción se mejora moviendo la horientación de la bobina. Excelente buen proyecto.
Projeto excelente.
Great video thanks 😊
Qreat video. One may-be stupid question: In the video you use LC circut of 433uH and 160pF. This set up will resonate with 19KHz signal. Correct?
how's the sensitivity gonna be with such a small LC? how's the performance of the IC? the only transistor radio i was able to build was a regenerative one which utilized a feedback loop, was running a 2n2222a and a soviet KT315G with rather large coils.
cz-7642 není polem řízený tranzistor ale integrovaný obvod s 10 tranzistory a funguje pouze při 1.5V a maximální kmitočet okolo středních vln(cca2 Mhz) u nás se již středovlnné a dlouhovlnné vysílače vypnuly takže to mám pouze jako dekoraci.Nyní používám regenerativní tranzistory při 1.5V na VKV.
You might be surprised to hear a signal or two on it, if you connect it to a long wire antenna, and use a good ground. There is NO WAY that it will receive signals from any distance...if you use it, with just the antenna coil shown.
Should have bent the ends on the components your soldering to the board at 90 degrees for better solder joint.
Паяю и ремонтирую с 60х. Но ваше видео, супер
Ещё одного выпустили из дома вечного двигателя.
Если ты называешь это хорошей пайкой, то ты реально ничего не знаешь. Человек многие ножки даже не прогрел. Так хлюпнул на нех припоя и типо держится. 1000% даю что если дотронуться к ним они отвалятся. При пайке ножка должна быть прогрета и припой должен быть со всех сторон.
amazing ❤❤sharing 💗💗
جميل جدا
OMG. When I first looked at this, I thought that it was made from a mousetrap! Nice little project for someone.
Hi very cool project where i can find the schematic??🙂 and do i need absolutely polyester capacitors?
As long as the capacitance is the same and can take the same current it doesn’t matter
@@Ruktiet Thanks a lot!!happy holydays!
I've built these kind of radio during my younger days but I need a long wire antenna to receive some signals ..
Very Nice❤️
Nice video ❤
Ola otra vez y saludos desde Galicia mi curiosidad porque en la foto de portada sale el proyecto con una bobina de unas cuantas espiras enrolladas y no la bobina de ferrita gracias
awesome.😊
YOU ARE SO SO SO NICE.
Your comment is important to me, thanks
Nice video ❤❤❤❤❤
I took "Electricity" in high school,,only thing i remember is a buddy putting a capacitor in the wall outlet and saying Run!!
pierwsze moje konstrukcje robilem na pseudo druku. Przez przewierconą płytkę przewlekałem elementy łącząc izolowanym drutem
tez tak robiłem ,nawet gruba tektura była fajna,bo nie trzeba było wiercić ,tylko przekłuwać,oporniki najlepiej przechodziły
Ха,ха,ха я в детстве 45 лет назад такие конструкции паял. Но тогда в эфире было очень много радиостанций
Saya suka radio ini
I have problem designing the ferrite core with those threads. What is the name of the thread and how can I get one ?
Use copper wire
@@inventorkr1
Thank you bro
How many turns and the wire size ?
@@ikehsamuelifeanyi4925 22 gauge wire, and about 70 turns.
Better to use Litz wire if you can.
@@AureliusR
Really ? Can I get that ?
How to determine frequency or incorporate adjustment to build other receivers in other Hertz ranges?
Change the value of the variable capacitor and the value of the coil
Liked and subbed
😅😅😅😅😅😅well information good show 😅😅
Bht achi video hei...
Bravo
Le falto incluir diagrama esquemático valores de resistencias y condensadores fijos😊
Ola saludos y mi link para ti por este magnifico proyecto ya a todo esto cuantas vueltas .de alambre van enrrolladas en la barra de ferrita y cual es su largo gracias desde galicia españa
70 T
Necesitas el ajuste de sensibilidad para el ta7642,un potenciómetro de 100kΩ ..por eso el ruido de fondo
Buena información, intentaré seguir tus consejos.
fabuleux
In 1957, I put a one-transistor AM circuit (not nearly so many parts) inside a little match box and used the radiators in the university as ground. Mine was perhaps not the first transistor radio, but I bet it was the smallest. LOL
Was it an regen receiver
@@TechniCraftYT - Simpler than that. It -- as I remember now 66 years later -- had a couple of capacitors & resistors, one transistor and a tunable coil. That was it.
@@fredrichenning1367 so you just had an crystal radio with an transistor amp.
Cool stuff. Would prefer a spoken explanation rather than music however.
Bu ses yükseltici hopörlörün yapım videosu varsa linkini yazabilit misin kanalını inceledim bulamadım?
👍❤️❤️❤️❤️👍
please make a AM radio with Ceramic Filter and IF transformers
To be fair there are simpler dial radios. I do like the simplicity of a transistor tuner radio.
IQ level matrix 🕶️👑
Ничего неуслышиш АМ сейчас отключен только шшшшшшип и усё😥
How is the RF demodulated in this circuit? It seems to be missing.
Do you have to use resistors with 5% tolerance? How does the circuit detect AM without a diode?
There is a diode in the transistor with zero threshold voltage, allowing fast switching.
Good..!
❤❤❤❤❤
Radio shack breadboard kits first project
Using ic ZN 414 ?
Buat histori saya.❤❤❤.
huuff i'm very miss that sound😭
😊 Where do I get a variable capacitor like that? Not in description or on Amazon.
From Ali Express
gozbx.com/r/Be82f6Sg4UOR
So these little radios all they do is take a modulated signal and demodulate it and create sound. It’s a cool little device when you understand how it works.
А почему контуром не попробовал подстроиться? А так все отлично, для тех, кто любит своими руками что-то сделать, а не только тыкать кнопки.
Veery good
AM for po go oc receiver ?
How much does the kit cost ..?
1 No.
Gracias muy amable me puedes ayudar para hacer paso a paso..y el diagrama saludos desde Ecuador
I think the most difficult part would be that antenna coil
Действительно, поймал все международные станции.. 😂
Bonjour monsieur votre démonstration ma intéressé . Je voulais vous demander une question si vous êtes disponible pour me répondre est ce que c'est vous même qui à fabriquer le plaquette où bien vous avez acheté ?
Je ne comprends pas exactement ce que tu veux dire, peux-tu expliquer ?
Good video! But...
①TA7642 is an IC (integrated circuit). Please do not write TA7642 with symbols like FET.
②Because the method of writing 7 is unique, some people may mistake TA7642 for TA2642.
③Please tell them that resistors and capacitors have no polarity, so you don't need to worry about their direction.
Thanks for your comment, I appreciate your advice
What is the gaze of the inductor
I guess the speaker on the right is an amplified speaker with it's own power source. ?
Yes
You will only pick up local stations. Sure you can pick up international stations as long as you are in range of the signal. And there are still short wave stations, but this radio does not cover those frequencies.
