Voltage regulator. 7803 is what you want methinks.

thanks, i didn't think you could get 3v regulators
There is lots of 3.3 Volt regulators out there, what sort of current are your looking for ?? Or are you just wanting 3 volts to run a couple of LED ??

lol, close a circuit that turns on a led when it's dark.. But i have played with ut and turned the circuit to take 9v

assuming its dc, you could use a voltage divider circuit (resistors). or maybe even a voltage regulator, but that would involve more components.

Thanks. I will muck around with both of them..
