The transistor (NPN) is reversed polarised, E is actualy the right pin while C is the left. That makes EB polarised in reverse and as Veb is only 6V that PN junction is break down when voltage on the capacitor rise up to 6V. As BC junction is forward polarised there is a shortcut curent that imediately discharge the capacitor over the LED. That discharge makes a short and bright pulse. This is a nonstandard usage of transistor and could also be damaged it if you take to large capacitor. In this situation the energy in Cap is too low to damage the transistor. Timing is defined by the RC constant until it reaches 6V. HIgher voltage makes that the the C quicklier reaches 6V, so it blinks faster.
I copied everything exactly as shown in video and light was blinking too fast for my liking - had to add a second resistor (variable type) in order to slow the blinking. I am using 12V power. I’d like to know why I had to add second resistor when I matched what was shown in video. Cheers
Video hatalı olmuş sanırım. Bc547'de yönü bize dönükken emitter sağ bacaktır. Ve bu devrede artı voltaj emiterden ters verilir. Devre doğru ama yazımda bir yanlışlık olmuş. Kolay gelsin.
I need a similar circuit for the 12V motorcycle direction signal, but the problem is that I have a 36V battery and I don't know what circuit I need to make so that the 12V LEDs don't burn. Does anyone know?
I am thinking decrease in microfarad (uf) in capacitor would increase the rate of pulses and resistance is necessary in order to run the circuit . Hmmm it is totally the opposite thinking . Hahaha . Mr zafer yildiz needs to answer us . He is the circuit engineer .

При таком включении транзистора происходит лавинный пробой , и у каждой модели напряжение пробоя будет разным , по сути он себя начинает вести как стабилитрон, потому как при таком включении мы переместились на противоположную часть вольт-амперной характеристики!

No voltage goes to B, how come electron goes through C-E ?
Please kindly advise. Thanks.

Used wrong capacitor
El valor del capacitador, si lo cambias varía la frecuencia
Nice video, what capacitor should I use for slower flashing? I would like 1 flash every 3 seconds thanks.
El transistor se utilizó como diodo 🤘🏼
And what? C B is closed....How Vcc connect to anode LED
The correct is: C, B, E . Was inverted on video but not matter
Excelente desde Caracas Venezuela saludos.
Güzel ve basit çok güzel olmuş eline sağlık

Look carefully after the transistor was inserted into the crocodile, there was a change of frame! This means the transistor has been turned over.
Excelente video zafer saludos desde El Salvador.
😮excelente información gracias 🤔

Alterando o capacitor aumenta ou diminui a velocidade do piscando
exato!
So smaller capacitor value means faster flashing or other way around?

Good job
It's work🥰 thank you
BC547 illaki şart mı ? Başka buna benzeyen bir parça kullansak olur mu ?
The 2n2222 functions too... I guess. Or you can try with another NPN transistor
Por fin lo que buscaba 😊
3 or 4 led flashing this diagram working ?
Bro....
Zafer Bey,daha düşük voltajlarda çalışabilen flip flop/flaşör devresi yapılabilir mi,örneğin 3,7v ile?
Güzel. Yalnız anlamadığım beyz tetiklenmeden nasıl oluyor da çalışıyor?
Use 1uF + 1Mohm, and make it much smaller.
*faster
What voltage for 1uF and 1Mohm?
I made it from a 2n2222 transistor And it works
Will this work on 12 volt led
I have questions for you instead of two transistor why not use Darlington pair transistor
Can I run it on 12volt bike battery 24/7
Can we add 4 led with input of 4 v???
Please reply
Super.
Ledin daha uzun sore yanip sonmesi icin nasil bir kondansatör kullanmaliyim. (maket arabama dörtlü yapiyorum)
Ein tolles Video. 😊Was muss ich machen, wenn ich 18v anschließe und fünf Led in Reihe schalten will.
Çok güzel bir devre oldu eline sağlık zafer kardeşim

What happens if you decrease the resistance .
Not 100% certain but I believe decreasing the resistance would increase the number of pulses per second as it will charge up the capacitor quicker
I am thinking decrease in microfarad (uf) in capacitor would increase the rate of pulses and resistance is necessary in order to run the circuit . Hmmm it is totally the opposite thinking . Hahaha . Mr zafer yildiz needs to answer us . He is the circuit engineer .
@@bunnyenergetic3142 I totally agree, with less resistance, there’s more current, but I don’t know😂

Power supply kitne ka he 220v ya 12v he
Transistor invertido? O sea al revés?
Çıkış kaç volt. Led sanırım 1.5 volt . Daha yüksek led takabilir miyiz.
i want you to do Let the led turn on and when off it will slowly fade out. with capacitor
Maybe put a cap in paralel with the led?
good
good 👍

Как 25вольт конденсатора пробивают n-p-n переход если подключено в запертом режиме, а пробитие у это транзистора 45-50v?

Zafer abi projelerinde daha az BC 547 kullansan daha iyi olur bulamıyorum

Bc547 ekmek gibi en bol bulunan Transistor
Her elektronikçide var
sa abi bu devewti 5 volt ada 3,7 ile çalışan devre nasıl yapabilirim cevap verirsen sevirim
BC547? Emitere bağlantı olmadan nasıl akım geçiyor? Birisi açıklayabilir mi?

If the base is not used then the transistor is Shurley biased off ? Stop calling me Shufley.

👍bro super
Нельзя так коротко откусывать ножки под пайку,можно вывести из строя одним паяльником без включения...😊
Cool. But it won't flash at 0.65 volts
Remember, the LED needs a certain voltage to light and the transistor itself needs a certain forward voltage to open like a switch
é led comum ou piscante
...зачем добавлять транзистор...если и без него схема моргает???
Sponsored by JLPCB ! Pease include a circuit diagram.
nguồn 5v thì sao ạ?

Есть ещё мигалка похожая на эту только вместо транзистора стоит динистор и питается от 220 вольт
Existen leds intermitentes.
