What you need is a step-up / boost DC-DC converter. A basic one would involve the use of an inductor, a switch (typically MOSFET), and a diode. There are also ICs that does this, just look up "boost converter" or "step-up converter" or "DC-DC converter". You can also look up those terms in google to find a circuit diagram.

Use a 555 IC in an astable mode (roughly 50% duty cycle)
Then use a diode charge pump to get the required voltage.

You will need to create an ac signal and then feed it through a transformer or some type of charge pump to step up the voltage. There's no way you can do it without converting to an a.c. signal.

Digi Key probably have these devices listed in their catalog and you could probably find a local distributor.
Why you want to re-invent the wheel.
Try to get a coconut for free from a tree-top, sometime you land back on your head.
Precision is the key in proven technology devices that you cannot easily obtain in homemade gadgets.

No. You need a DC DC converter specified to convert 5V to 12V.

you can use readymade DC-DC converters from texas instruments....they even sample some of the models for free...check their site...
