ok, I am totally unsure if this is the apropriate forum for this but Ill give it a shot and if I'm in the wrong spot, then feel free to ignore me or redirect me. but please no flameing...
ok, I am working on a small project for fun involveing small electrical components. the issue is not so much the project itself but the powering of said project...
I am adding a micro hard drive to a device called a gp2x. its a portable gameing console. the modification requires a change of power configuration.
thus far all of my power needs can be met by the existing hardware and other points of interest have been covered by other people but for the actual power configuration itself.
basically the system uses a pair of double A (AA) batteries (2500mAh preferred) the hardware I am adding requires 3.3V @ anywhere from 0.6watts to 1.4watts
the gp2x runs on (obviously) 3v AA power... so here are my questions:
1st: is there a simple way to create some kind of power spliting device to give the gp2x 3v and the HDD 3.3v at their respective required wattage?
2nd: Id Like to power this all with a battery, what kind of power output would such a battery need to give to be able to operate for a decent period of time?
3rd: Id Like to use a RECHARGABLE battery is there any way to build some kind of simple chargeing unit for the above described battery that can "autosence" when the battery is "full" and stop chargeing?
I can figure the rest out but I need to know these three things and how to do them... can anyone help me out? if not, can anyone point me to somewhere/someone that can?
