I'd like to convert a 3.6V cellphone Li-Ion battery to run a 5V circuit.

There seem to be a couple of options to enable 5V, but i'm mainly wondering if there are any tips and techniques that can be built from junk box parts.
Quite a few chips are around, from MAX and other firms...but am thinking there must be something along the lines of using diodes for voltage drops, in reverse. Amperage is no issue, the circuits will run in the 200-300mA range.

I could put 2x3.6V pack in a device and use a 7805 for a smooth 5V...but wish to only go along that route if nothing straight forward seems feasible.

Main reasoning is that a whole world of possibilities open up with my large collection of parts, if I can just get 5V for circuits.


Still in hope of finding a chip based solution, i'm currently looking through various items in boxes for one of these:
