Nice project bro. I having doubt . How to change the frequency of this FM transmitter? Or it fixed on only one frequency because of normal FM transmitter there is LC tank oscillator and used trimmer capacitor for set Frequency.
Gracias por compartir, estos proyectos tan interesantes. Dos preguntas, cual es el alcance de esta emisora y emite en mono o estéreo. de antemano agradezco tus respuestas.
Great job sir, but please tell me how did you make that circuit FM receiver. Would you please, send me this circuit diagram with details of the coils? Thank you.
Saludos desde México. ¿Donde puedo conseguir estos circuitos o algo similar? Es que por mas que los busco no los encuentro ni en la tienda local los tienen. Y otra pregunta: ¿puedo usar este circuito como oscilador para medir capacitancias de entre 0 y 100 pF? ¿es posible usar la señal de salida no como señal al aire sino como voltaje medible mediante un filtro RC o LC?
Nice but beware that circuit might be illegal in some countries because of the wide spectrum of high, unfiltered harmonics! There *should* be a HF filter to constrain the output bandwidth to the carrier band, therefore [at least] one coil is an absolute necessity.
I am wondering why you say Pf when the standard notation of caps. is different? like an example: 104 is short hand for .1 microfarad. right? And in the CELL PHONE JAMMER video the output of a 555 is negative going; so the V out cap was labeled backwards... I been a hobbyist for 40 years. So I am confused at this time and ask clarification?
Muy curioso el diseño y el sistema de oscilación,me imagino es a corta distancia..pero suena super y hay que tener en cuenta el integrado que sea de alta velocidad o sino pailas..no funciona..
nice, but I'm afraid you'll have much frequency-drift, high energy-consumption (in this setting you'll not transmit a long time with battery - so, at least you should remove the LED (what for, btw))and I'd also replace C2 with an adjustable C / Trimmer to influence f. Did you check the transmitted frequency - what is it? If f is not in the common range (for Europe lets say 87 - 108MHz) you will always need an unique receiver to get it and you won't be able to receive it with common radios. .What about the range (distance) - I'm afraid it's just working for a very little distance, isn't it? Anyway, I love the way and the accuracy you're doing an presenting your circuits - good job :)
ja, mit der Stromquelle fängt's natürlich gleich an - das hält nicht lange. Dann kommt noch die garantiert begrenzte Reichweite hinzu und von der Temperatur-Drift gleich ganz zu schweigen (die f wandert da rauf u. runter, dürfte sich aber nach einer gewissen Zeit stabilisieren). Zum Basteln und Experimentieren an verregneten Nachmittagen jedoch bestimmt bestens geeignet :) LG
Instead of sn74ls13 can I use sn74ls132 which has two input not like urs which has four.Becoz Im not getting 74ls13 in market as well as online so.Pls reply as soon as possible sir
You should test the distance and the stability, you put transmitter and receiver side by side, we can't see any of its performances, and there is a coil... so it has a coil

Te quiero sugerir un proyecto, ya que tenés la capacidad en todo de realizarlo y no lo he visto en youtube. Yo se que se fabrica tanto receptor fm como emisor fm, y son pequeños los que vi en youtube. Hay posibilidad de que hagas un Walky? Por ejemplo: Walky A, emite en 90.0 y recibe en 100.0 y; Walky B, recibe en 90.0 y emite en 100.0 - Sería un proyecto genial. Gracias
Actualmente estoy trabajando en un proyecto walky talky de 500 metros de alcance, gracias por su sugerencia, y también gracias por su valioso comentario MG Entertainment.
No. It is very primitive transmitter, working in auto-generation mode, without frequency stabilisation and without output amplifier. If you will connect big antenna - unknown effect.)))
@@Red_Avenger Thanks for making sense! The circuit could be useful for educational purposes, not much else. Unfortunately no explanation is given in this video. (Me thinks the creator has no idea. He writes 104 is 104pF)
Hi Dear Already im make this circute but im used IC 7310 its working fine (pin little change )but very short range only 10 mtr getting need any changes?
I successfully build this tiny transmitter, but it's noisy when I use 5v Phone adaptor to supply this circuit... This device uses Harmonic frequency, so I can hear the transmit signal in freq. 64MHz receiver too
Hola Como estas espero que muy bien me gusto mucho tu video y como realizaste el transmisor FM, me gustaría saber si en vez de una batería de 9v colocarle una cargador de 9v y hasta que distancia puede llegar a emitir? A y otra cosa y en vez de colocarle un celular se coloca en una computadora para emitir música desde allí puede pasar algo al computador?

Remember the band allocation/freq allocation in your country, if you break some rules, expect a van with rotating sat dish
I love this channel because of your simple & nice circuits. keep going bro 😍
without coil except that coil there😁👍
the coil isn't mandatory, you can use a normal wire for antenna
How long?
1/4 the wavelength on the output and 1/4 the wavelength on minus.
ayiok
@@hnoushahi the length of the antenna wire will be
around 75 centimeters
Nice project bro.
I having doubt . How to change the frequency of this FM transmitter?
Or it fixed on only one frequency because of normal FM transmitter there is LC tank oscillator and used trimmer capacitor for set Frequency.
This give me a lot of help! Very Thanks for you and your Video!
You are welcome 🙂
Really nice pls make a mobile signal jammer without coil as same in video
104 means 10+4 zeros so 100 000 pF or 100nF!:-)
100nf
Creative Science thank you very useful project!!! :-)
welcome bro
Indeed
Very good circuit sir. I would use it if I knew electronics.
😊
Super brother,,, what is the range of TRX and rxr ?
Nice build.way back in 2013 I did it but mine was a single transistor FM transmitter and that is highly unstable. I still have that circuit board.✌👍
:)
Fm
@@safikulalam7786 yes FM now what you wanna say please explain.
Love it, "Fl transmitter without coil" and you can see a coil on the vidéo miniature 😂
He said that the coil is optional we can use wire instead..... coil is used as an antena....
But the video doesn't say optional it says no coil (thumbnail

Dos preguntas, cual es el alcance de esta emisora y emite en mono o estéreo. de antemano agradezco tus respuestas.
Muito bom! Este transmissor teria quantos metros de alcance? Poderia usar um canal de sintonia?
Thank you very much bro.
But 104pf capacitor is not 104pf , it is 100000pf or 100nf. and this circuit how distance range ??
Ali A that's my mistake, circuit range is 50meters
Ok bro,thank you
So, in circuit I have to put a 100 nF capacitor instead the 104 pF?
ALEFILES , Yes
yes
what's the transmitter frequency, how many MHz?
Great job sir, but please tell me how did you make that circuit FM receiver. Would you please, send me this circuit diagram with details of the coils? Thank you.

How long this work? what ic does?
Hey friend where u bought Clad PCB in India online or local store plz help
capacitor marked with 104 is not for 104 pf, it's really for 100,000 pf
You should test the distance and the stability, you put transmitter and receiver side by side, we can't see any of its performances, and there is a coil... so it has a coil
We made Amplitude modulation AM transmeter in 1987. In 1994 we made audio video transmitter through ch. 4
Very good ...
LONG range????
How we can made this circuit worked along distance!!!
By using an RF amp I guess.
можно и на выводах микросхемы напаять и залить термоклеем или в маркер положить
It is sending sound of microphone or aux?
is it in normal frequency range 88-108MH ? Can you please revert

The 104 pF capacitor means 100 nF? Or is correct 104 pF?
Thanks a lot!
Greetings from Argentina!
ALEFILES, u can use 100nf and thanks
I have constructed this circuit on breadboard but not working anyone can help me
the capacitor marked 104 is 100nF (0.1µF) also the one marked 103 is 10nF (0.01µF)
I see there is a coil in the project. However, I would not get too wound up about it.

I think that 50 m range is low
when a suitable antenna it must be more than 500 m range.
Is it right ?
No.
It is very primitive transmitter, working in auto-generation mode, without frequency stabilisation and without output amplifier.
If you will connect big antenna - unknown effect.)))

But it is also a good choice for beginners
How to calculate the Transmitting frequency? I mean which section is the oscilator?
