So I completed my first frontlight! I tried backlighting, as have many before me, but destroyed my calculator. So here it is.
This was the LEDs I used. 10 LEDs in a string, for $1. It was bought at the Dollar Tree, and was really an excellent deal for the purpose! If you cannot get them at Dollar Tree, here is a link to an eBay listing for $7.
Here, I sanded the LEDs down, for they were large and unwieldy (I used a belt sander):
Then, I cut off the plastic casing, desoldered all 20 joints, trimmed the green wires shorter, and relodered them together more tightly:
The finished product, before taping the paper box together (hot glued to it):
I'll get a pic of it in the not-dark in a bit, but until then, here it is in operation (very ritzy! ):
