Why Transistor works without BASE ? I dont understand how that can work. Do you have a idea why it works ? Thank you
the quation is how the transitor let the current pass without connecting the base 🤗🤗🤗
I randomly found this video and tried this, everything works well but the buzzer is a little bit quiet in my projects but honestly it's just AWESOME, your project made me make finnaly a blinker circuit thingy while i tried months to do it
Perfect pitch for my purpose, but to many pulses per second... would I have to increase the capacitance to slow down the frequency, or the resistance of the 100 Ohm resistor? Perhaps if I increased it to 0.5k?
I finally got all the right stuff and got it working! Thanks for sharing!
Nice n simple idea thanks for video
Are the LED and the 100 Ohm resistor needed? If you don't need a blinking light?
Love it man!
500th like, btw awesome channel
Nice info, thanks for sharing :)
Muchas gracias lo que estaba buscando un zumbador para ac 110voltios 👍
You should explain to users if the buzzer is active or passive. Because with this last does not work. If you post ... explain.
@TechSaw Why leave the base of the transistor unconnected?
I'll use this for a DIY car door buzzer, using the car door button to activate or deactivate the circuit. It already provides 12v but I don't know the amperage value. I hope it works, thank you!
Hello, how are you ? So, I was wondering if this buzzer is passive
VERY GOOD WORK MAN VERY GOOD WORK 😮😮😮😮😮😮😮😊😊😊
I'm wanting to do this with 3.7v. will it work. And if I use three red leds using resistors for those leds won't change this at all will it?
This circuit works. It should be 12 volts and the current should be above 7 ampere
Use Active Mini Buzzer!
I am talking about 12 volt circuit
How come this doesn't work for me?
I have the exactly set up for the fifth time now but I get NO sound, NO light 😥. I am frustrated now. I even tried to use car battery but nothing changed.
@Tech saw
Is there anyhow you can assist please?
will to work for passive buzzer ?
Does it work with only 3V?
Do you have the part number for the buzzer? I think I have all the other components in stock.
Buzzer pasif or aktive brother?
This is Esaki's Oscillator
Very, very super
nice sir
Kya hm buzzer ko 3 volt chla ga bta do
Nice and practical project 😀👍 thanks
Thanks for shareing

1.BC457
2.Buzzer
3.220uf capacitor
4.100ohm resistor
5.22k resistor
6.LED
I made it but the LED is not working and the sound is like a watch tik tik tik it’s not beep sound whyy🙄😓
Your battery health was low
Is it passive buzzer
Thank you
Se vídeo é bom,
Acabou de ganhar mais um escrito 👍
ur using an active buzzer but what if it was a passive?
can you make a 5v version?
Good idea 👍
ये तो फक फक आवाज करता है 😁😁😄🤪
input dc or ac?
Thanx for this nice circuit..I think to use such a circuit in boiling kettle running with 3V or 3.7V...
Thanks for sharing
good work

what if i will use 12 volt 2 amp adaptor. will this work?
Components value please. 1/4watt resistance ya phir 1/2 watt.
Can it work on 12v?
I just put a similar circut (5V buzzer) with a 330Ohm resistor in the circuit of my motorcycle turn signal and works fine. Not sure though, how long ;)
Keya kam me ayga yea ?
how can get beep sound to longer??
I would think to use a different resistor for the transistor. You could also leave out the transistor to have a constant beep.
how can we modify it to auto off after 5 seconds?
It's an active buzzer. By appearance, the bottom is sealed. You're welcome!

I want a diagram of a circuit that contains IPS. Whose job will be to beep 5/6 times when the power goes out. 2 times per second. And when the electricity comes, it will beep once. Please help me with the diagram and what components are needed.
Im try,but n't working..something differnt between my country
I want more than 3 volt, at the point of LED.like 7.5 volt
What is input voltage?
It shows 12v in the schematic
Good project
Sir, can you put something else instead of 220 uf capacitor. I put 220uf 16 volt didn't work just buzzer continuous sounding.
Please help.
pq toda vez que faço isso da errado ele não pega
which R I use to be able to connect that circuit to 110 V?
Hey! How do you increase the time between beeps?
By using different capacitors

Supply ac ya dc
Dc
Perfect
КРУТО
Este circuito es un oscilador para audio.
Transistor konsa h yai PNP hai Ya NPN mere NPN transistor main kaam nahi kar raha h yai circuit
why don't you just google that transistor ?
Components number?
Be sure use an active buzzer otherwise that circuit will not work.
what was the voltage of you use power
Supply 12v
I search this for my motorcycle and I try it.... the buzzer will active when my motorcycle is turned on but the machine are not started....
thanks for sharing!
Connect it between the battery light if you have that. The battery light is on when the engine is not running, because the battery is only charging when the engine is on.
Like. 👏👏👏👏👏
you cant say 2.2K ohms instead of 2K2?
Good
Não funciona! Estude mais seu circuito e/ou veja sobre a teoria de transistor, ok!
Exatamente igual........ NÃO FUNCIONOU!!!!!!
Bc548 chalega
Naah uske iye connection ulta krna hoga
No work
Fake
Good idea👍
