solutions for noobs, the rest of us probably have adjustable power supply:
1. use 3.3V from the PC PSU. (orange wire).
2. use cell phone battery they are usually 3.7V, drain it a little till about 3.3V.
3. open your DVD player, the chances are 99.999% it has 3.3V stabilizer and some internal circuit running on 3.3V. Run + and - wires and that's it.
4. drop 5V usb power with two diodes or some resistors, one in parallel and one in series.
hope that helps
