Im curious why

Noone had any advice about running Cyclone II based boards off rechargeable batteries? Is there something I dont know where it's a bad idea?

Thanks, my research is pointing towards National Semiconductor LP3990s for the 1.2 and 3.3 volts I'd need to run a Cyclone II, not sure if the version of Quartus II I am running (free vers with cyclone II dev kit) will work with Cyclone III.

Their reference designs show more complicated board designs with several capacitors. inductors and resistors, I may try to get by with just capacitors from input voltage to ground, and from output voltage to ground.

I am not sure if that linear technology one with the QFN package is something I can hand solder, with the contacts on the bottom. Maybe when I sell a few copies of my first game design, the second version can have that.
