how can i activate a seperate circuit? - Electronic Circuits Projects Diagrams Free

Captain-Bartholomew · 2nd January 2008, 06:51 PM

if i take a circuit powered by a button cell or other small battery how can i use that to activate a seperate circuit with more power?

please help!!

Your not really giving any detail here. Are we talking about 1 button cell or many? How many volts does the small, low power circuit operate on?

What is the high power circuit? You need to add more details on what you want to do. It could be a flashlight or a 480v 3 phase contactor for all I know.

Make a drawing or photo what you want to achieve !

Your question doesn't make any sense.

Hi,
There is a device/circuit called a 'Joule thief', if you Google for 'Joule thief' you will get lots of hits.
Its a small circuit that will run off a 1.5Vbty or cell and drive and LED etc.

i think what you need is a relay . i have nerver used one so i dont no much about them but hear is a diagram

From Wikipedia
Relays are used:

to control a high-voltage circuit with a low-voltage signal, as in some types of modems,
to control a high-current circuit with a low-current signal, as in the starter solenoid of an automobile,

hi Matk,
The problem is the low operating voltage say,1.2V to 1.5V,, I have not seen any relays less than 3.3V/5V as a common item
I suppose he could wind his own relay coil, using a reed relay???

Also usually, as the relay operating voltage is lowered the operating current in the relay coil has to increase.

hi eric

I separate those word, Can you figure out.

ericgibbs · 3rd January 2008, 11:52 AM

hi jumides,
I think we are all waiting for the OP to give us more information.
IIRC, he is complaining on another thread, that no one has answered his question...

jumides · 3rd January 2008, 12:07 PM

hey!!, I found his another post " Very Small Transmitter ", look on his "find more posts by Captain-Bartholomew". (view Profile).

Brian Hoskins · 3rd January 2008, 03:09 PM

No, there was another post in which he basically fooled around and complained. I guess Nigel probably binned it, which is all the thread was good for to be honest.

He posted the same question in another thread. He obviously has no idea about how to use a forum and ask questions.

Perhaps there should be a tutorial that these sorts people can read before they post here. Then if they behave like this, Nigel can email and PM them a link to it and if they ignore it he can wallop them with the heaviest banhammer he can find.
