Hello;
I am searching for a IC LM3909
Any electronics store with ONLINE PAYMENT option out there?
I am not so bent on going out to the bank to do transfers cause our vehicle will not be with us for several days.

This is one store but the inventory is do HUGE that i cannot find the component there.

For the curious people out there:
I am planning to do a simple flashing circuit with it for my model railroad after my exams.

if all you want to do is flash leds - consider using a 555 which is available
in every neighbourhood

I want to use it in the given circuit digram:

Would the wiring be the same?

no - different circuit ... but just as easy


google for ' 555 led flasher circuit '

all right!
Will do.
Thanks!

I usually buy electronic parts from Electron Components. They have the IC you're looking for here. However, as Saikat sir said a 555 timer is much easier to find. I actually soldered up a 555 blinker circuit for one of my schoolmates and it is quite a simple circuit.

EDIT: My bad looks like it is out of stock. Take a look at this for an idea on how to make the circuit with a 555 timer. I could solder one up for you if you're interested since I probably have all the parts lying around.

Sir;
Electron components is my usual electronic store.
Everything i buy is from there.
Ill look up on the 555 circuit.
Thanks for your help.

I you just want to flash LED , flashing LED it self is available ! Not sure whether it's avail able locally

they flash too fast.
I want something suitable for

Here the circuit could go under the layout with only the led on the top.
Once again; flashing leds are tooo fast
