Yar i did one a while ago


I modded my Casio CFX

Basically i did a front light with white led's, illuminated its on/off switch with a blue led and added a mercury tilt switch for the exe button

Video:

The video was actually done in the premature stages of the mod

i ended up doing a proper plexiglass front light that spread accross the front of the screen like a GBA SP  one

and adding the blue led's to the switches and added another switch to turn off the tilt if i needed

Needless to say dude, it makes you the envy of your maths class

EASY!!

Just run all your led's in parallel with the positives connecting to B+ and negatives connecting to B- with a switch if you want and using appropriate resistance.
