Good idea, except how about using conductive paint that also glows in the dark. Then you can find you N900 in the dark.

If you make the wires thin enough, they will glow, but only for a short time.

/me thinks hibernation is cool :-)
That's also the easiest way since involves no hardware modding.
Not that I have any idea how to start though...

Why wouldn't this work? It works with the N810.

I'm hoping #1 works. That'll open up so many simpler options:
- external charger\reserve battery packs
- temporary power for battery swaps

Just found this on JR.com, it has a bigger lith-ion rechargeable battery built in, so even more juice for the N900.

that would be the greatest solution. if it really works that way. because i think new symbian phones will shut down even when charged if you remove the battery...

and bundle 2 batteries together to usb reserve could be the smartest solution. one could first use two batteries with no external gadgets. and when second is wearing out, with external pack one could almost double the uptime(1100+1100mAh vs 1350mAh+1100mAh)....

on an other hand, regulator eats some of the batteries power when connecting 2x3,7v -> >7v and regulating to usb 5v. so it isn't really 2200mAh compared to plugging batteries to battery contactors. maybe the simplest solution would be 6pcs cheap AA-batteries and a 5v regulator just to keep the device running during the change.


could someone confirm that does the device stay on when removing battery while charging?

the hibernation seems a good idea.

the backplate could be extended to the edges of the camera and stand to fit a bigger battery.

the whole case could be painted with CIGS to have it charged or at least assisted.

I dont want the mod to change overall sizelimits to still fit in my pockets and I dont want to carry any additional stuff with me apart of a spare battery (hibernate change)

If it's USB reserve, the link I posted from JR.com has both a USB plug and standard power plug built in on the portable charger
