12V timer circuit

[dom14]

Hey Guys,

I'm looking for a timer circuit that cuts of the power after 10 seconds or so.
Whether it's a finished product or a hobby electronic type build circuit are both good for me.
I can build it from parts from Jcar, or ebay.
But, I prefer a finished unit so i can save some time.

Basically the delay circuit I'm after should turn the power on for ten seconds when the ignition
is turned on, then cut the power until I reset(turn off the ignition and turn on again).
So, obviously I'm looking for a 12V timer unit that controls 12V power with a timer.

I'm wondering whether the below circuit would do that.

or any other suggestions, links, etc will be appreciated.

thanx

Probably be fine but at $4 if it isn't then no biggee...

Sounds like your after a flip flop cct

More expensive option http://www.jaycar.com.au/timer-progr...e-12v/p/AA0378 any good?

You could use a cheap turbo timer.

What is a "turbo timer"? Where would I get hold of a one from?

It is a biggee, 'cos I have wait until end of time for it to arrive from China.
I wonder if there's a local supplier of that unit or similar.

Do you have a simple circuit blue print that I can borrow?
Thanx

P.S. Jaycar solution is too dear for me, 'cos i will need few of them for different applications.

'ere ya go Cobber https://en.wikipedia.org/wiki/Flip-flop_(electronics)

Most hobbt circuits will use a 555 timer and the flip flop switches a relay

What??!!!
You're putting me through a digital electronics course?
I've forgotten most of the circuit design stuff, and definitely digital stuff.
I like the idea of looking at a schematic and putting the bits and pieces together, and then get
the damn thing to work.
And I care very little about what happens inside the 555 timer these days.

This looks promising. Apparently based on 555 timer.

Back when Dick Smith sold real electronics the catalogue had a data section with schematics & all the info you needed to build the "one shot" that you want.
You will not be able to build anything for the price of your e-bay find, a piece of veroboard will cost you more. I once got some blank 555 boards from RS Components for a project, but they were way more that what you are looking at.
This kit from Altronics is pretty good, but $35 might be out of your price range and you have to build it.

Sorry mate. Re-read your post. A Turbo timer will not go down to seconds, lowest setting is usually 1 minute. ( a turbo timer is a timing device to allow a turbo to run on and cool down )

Spoil sport... I was about to tell Dom a "Turbo Timer" was a normal FactoryTimer with an aftermarket Turbo, Chip and Water to Air intercooler.
