Nintendo DS Slot-2 Lights

How to make a source of light out of 2 white leds & your filler cartridge(the useless thing that came in your ds's gba slot).

I've found a cheap set of wardrobe lights, cheaper than white led itself; so I've decided to use them, instead of buying some...

Open up the cartridge and prepare some wires...
p.s. take a look at the polarity (2nd image).

Desolder 2 leds
solder them to the wires
look at the 7th picture and make something similar
put some insulating tape between the wires in the cartridge

Take the bottom part of your cartridge and engrave it with something, like a dremel...
then detach the internal plastic separator part.

Put the pcb into the cartridge case (use some glue to fasten it);
close the case with the screw (do you remember where you put it?)
add some glue to the leds(to prevent short circuit).

You've finished!
