Im doing an window LED mod on my calculator out of pure boredom.
A Friend also suggested a rechargeable battery thru USB which is also entirely possible.
This is a WIP, expect more pics :drunk:

Hope you dont mind the double post, if you do, you can go ahead and merge these.
UPDATE:
I have found two switched power sources (turn on when you turn the calculator on), both are clocked at 2.3v, perfect for one LED each.
The black is a ground you can use, and red are the 2.3v sources:

Doing the wireing/window cut now. Anyone interested in a tutorial?

Got it lighted, still arranging the LEDs to give me the best light.

Seems to be coming up nice..... How about making it a button reactive calculator ? Lights flash a different color whenever you press a button.... :D
-
Very possible, There is so little room in this calculator though, Finding space for the two 3mm LEDs that are in there is hard enough.
I would have to do SMDs, and I really hate those buggers.

you should backlight the screen for doing math in the dark lol.
-
OMFG im gonna start doing one of these
-
lol is that a ti-81? cuz i think i have one of those somewhere i might do this now and squeeze a ipod nano shuffle in there somewhere so i can listen to music from my calculator, also what did you use for the window?

i bet he used a a cd-cover
