Simple led flasher using bc547

[@AsstDW]

May god bless you, thank you so much

[@OnboardingInformation]

Greatest flash ever

[@sgautomation402]

thank you 🙏

​@@sgautomation402How many volts is a 470 capacitor, sir?

[@ALEFILES]

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!

[@peatmoss4415]

It's called an Esaki oscillator.

[@victimovtalent6036]

can you makes for 3.7V battery

[@peatmoss4415]

No , 12 volts or more.

[@stanislavp681]

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.

[@peatmoss4415]

It is called an Esaki oscillator. Look it up.

[@sgautomation402]

u r right

[@wakuwaku3190]

can someone explain to me why it behaves like that? thanks❤

[@Nmrera_21]

Can you make tutorial led flashing use 3,7 battrey?

[@sgautomation402]

sure

[@yxcvbnmmnbvcxy544]

This circuit is real but use bc557 transistor

[@block4671]

Why this is not working?

[@torc_mp4554]

By changing thebvalue of resistor can we change the speed

[@sgautomation402]

yes

@@sgautomation402 thanks

[@SLSachintha]

9v can be supplied?

[@sgautomation402]

yes

[@aradashrafi846]

Why transistor base have no voltage Remember transistor normally block current until a voltage produced to base pin(also current)

[@sgautomation402]

check esaki oscillator in google

[@khulekanimlandeli470]

HOW MUCH SUPLY VOLTAGE?

[@sgautomation402]

5v

[@Neo_designs]

Should the base just be empty?

[@antonorlov666]

No

[@ilovebrisket55]

Yes

[@deniska8785]

@@ilovebrisket55how? Interference?

[@dipelectricalselectronics230]

Doesn't work without giving any base voltage to the transistors....

[@TechniCraftYT]

The transistor has a breakdown voltage

[@Vaiespionaroc.....]

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.....

[@aarshsinghal2129]

fake video guyz dont fall for it

It's working bro

[@sgautomation402]

on what basis you are saying, do want me to do it live

[@sgautomation402]

excellent 👍👌

[@nethmadehen1461]

The base pin is not used

Bro i want to increase the flashing time what can i change in this circuit

[@marspot]

Capacitor

[@sgautomation402]

yes it works on rc values changing them changes frequency

[@astronic4522]

Nice project

[@sgautomation402]

Thanks

[@subbu030]

How to increase the flashing rate

[@change_your_oil_regularly4287]

Change capacitance &/or resistance values

[@penguinoc63]

​@@change_your_oil_regularly4287to add to that, get a capacitor with lower microfarads - it will store and release the power faster

[@luisjose2169]

​ Es Correcto

[@luisjose2169]

Yo creo que es inestable. Dependiendo de la calidad y tipo de componentes

[@gallosandgames]

no funciona.

[@Vaiespionaroc.....]

Tens que o alimentar com 15 V .....

[@ZenithDuwadi]

Howww

[@mustafaeroglu3140]

12 v ?

[@sgautomation402]

yeah it's 12 v dc

[@justtinkering6713]

​@sgautomation402 12 volts too high

[@cancaonegro]

9V worked pretty well here

[@justtinkering6713]

Got a different circuit flashing at 0.8 volts, for 2.5 years

[@ConstabeastYT]

Will 9v work????

[@subbu030]

Nice

It works perfectly 🎉

How does this work even

this is a blunder

Totally fake.

Hmm where is the diagram?

[@washer_person]

Are you for real. Only LED transistor and capacitor and you diagram

[@penguinoc63]

​@@washer_person I mean, there is also a resistor......😂

I will post

You didnt used the base pin
