hey everyone.. i have 4 AA batteries and need to sqeeze 12v out of
them. can this be done?

Hi, Sam. The easiest way to do it is with a 555/voltage doubler.
Here's a link:

The output voltage is slightly less than 2X the input voltage, and it's
not regulated. That means the output voltage will drop if you need
more current.

The circuit shown is good for about 25mA with no more than a volt of
ripple.

If this doesn't do the job, please post again.

Cheers
Chris

There are various methods, all of which involve active electronics.

To suggest the best answer one would need to know more info like load current
and ripple / regulation.

Or a synchronous vibrator! You could probably make one with reed relays.

12000V from 6 isn't a huge problem 12V from 6 is much easier.
have any idea of how much current or power you need (how many
amps or how many watts)

Can a voltage multiplier be run off unpulsed DC?
