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

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.
