Calculator mods. WIP

[scott]

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

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?

Seems to be coming up nice.....  How about making it a button reactive calculator ? Lights flash a different color whenever you press a button....

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.
