And the BASE of the transistor are unconnected? In the video the capacitor is connected between emitter and collector, and the 1K resistor is connected to the emitter and the other terminal to (+)... BUT the BC547 is a NPN transistor, so the collector have to be connected to (+), and the emitter to ground (-), and in the video is connected in reverse voltage... Greetings from Argentina!
It looks like an avalanche breakdown of a transistor. When the current decreases and there is a temporary voltage spike on the collector, the transistor turns on. Usually, the transistor burns out due to thermal breakdown, which requires sufficient current.
Sim, funciona..... é o que se chama de saturação forte, mas tem que ser no mínimo 12 V ......o ideal é 15 V. É o que se chama de oscilador esaki, ou algo parecido.....

It's called an Esaki oscillator.
can you makes for 3.7V battery
No , 12 volts or more.

By changing thebvalue of resistor can we change the speed
Greatest flash ever
thank you 🙏
9v can be supplied?
HOW MUCH SUPLY VOLTAGE?
can someone explain to me why it behaves like that? thanks❤
Can you make tutorial led flashing use 3,7 battrey?
Bro i want to increase the flashing time what can i change in this circuit
Capacitor
yes it works on rc values changing them changes frequency
It is called an Esaki oscillator. Look it up.
Should the base just be empty?
No
Yes
@@ilovebrisket55how? Interference?
Why transistor base have no voltage
Remember transistor normally block current until a voltage produced to base pin(also current)
Uf=microfarad=1000 nanofarad
Mf=milifarad=1000 microfarad
fake video guyz dont fall for it
It's working bro
on what basis you are saying, do want me to do it live
excellent 👍👌
The base pin is not used
Bro transistors having breakdown voltage@@nethmadehen1461
Doesn't work without giving any base voltage to the transistors....
The transistor has a breakdown voltage

This circuit is real but use bc557 transistor
How to increase the flashing rate
Change capacitance &/or resistance values
@@change_your_oil_regularly4287to add to that, get a capacitor with lower microfarads - it will store and release the power faster
Es Correcto
12 v ?
yeah it's 12 v dc
@sgautomation402 12 volts too high
9V worked pretty well here
Got a different circuit flashing at 0.8 volts, for 2.5 years
Will 9v work????
Nice project
Thanks
کاملا واقعی است ولی بگیر نگیر داره
couldn't understand what u r saying, but thank you
@@sgautomation402 he sayingyour circut is real but not stable sometimes
Yo creo que es inestable.
Dependiendo de la calidad y tipo de componentes
no funciona.
Tens que o alimentar com 15 V .....
Howww
😂😂😂
Totally fake.
u make one u can understand
Nice
Fack video don't work
You are fack
It works perfectly 🎉
Hmm where is the diagram?
Are you for real. Only LED transistor and capacitor and you diagram
@@washer_person I mean, there is also a resistor......😂
I will post
Fak
what video you want I can make it challenge?
this is a blunder
You didnt used the base pin
Fake
I don't do face videos, I am an electronic engineer having enough knowledge.
