want better battery saving?



depending on a supplier of batteries and specific covers...
dwindling away...with every passing year...

Is not the way to go.

This is a better ..

DIY...

take an old n900 battery...
take it apart.
remove the battery guts...
attach requisite wires from battery shell interior to exterior of n900..
place battery back into the n900..with pre-drilled hole in back cover of n900 with rubber gasket in it...so dust and moisture do not get in...pull wires through...
connect ..
to the output of this...

adjust voltage...
connect a wire with usb end to the input...of the LM317

Use any battery storage device...utilizing usb....or any storage device that utilizes an adapter that fits a standard usb...
Or plug into any wall outlet using an adapter...
or plug straight into the usb of a computer to utilize it's power.

I suggest as well to make an enclosure for the LM317
and to fix and set the voltage dial so it doesn't get altered ...accidentally.
