Simple blinking led circuit?

[sweeduino]

Hello!

Got a great idea for a christmas gift that only need 1 led blinking with about 1s cycle. 1s on 1s off.
First idea was to usa an old arduino but then I thought that its too simple and started googling. But I can't seem to find a simple circuit that has the "that will work" feeling. So can someone please help me?

It will run off batteries.
1 led.
Components that I can find easily.

Will reveal my idea after Christmas!

Sounds like a job for a 555.

BTW, let me try to guess the idea.
Rudolf's nose?

Or, how about Nick Gammon's ATTiny gadget?

Thanks!
I knew it was simple but i couldn't fint that clear solution. This will be my first encounter with the 555.

No nose. You'll see...

There's a bunch of dead-bug 555 circuits around the net, ie the external components are soldered to the legs- makes it very small.

Nobody nose the trouble I've seen...

Can't wait.

Feeling adventurous?

All you need are a couple of transistors, resistors,  capacitors and you can make a flip flop astable oscillator..

Or with a 2n2222 and a capacitor you can also make an oscillator. (2n2222 specific)

So this was my idea.

No wonder I failed!
Did the nerd that got it like it?
