This is just an idea but..
I see a lot of people wanting to get LEDs or ELs in their calc, to have a back light. This turns out to be hard to assemble in many cases (which sometimes results in complete calc-messups) AND drains your battery level like a cruel monster.

So, I was thinking (already a while ago, I just post it now) why not use something like this? http://www.nadco-inc.com/glowindark.html
1 It's free energy, so it doesn't use your batteries
2 It can give light for up to 8 hours (make it 4 hours decent light )
3 I think it would be eeeaasy to assemble

Why? Well, last time I was screwing around with a calc (simple + - / * thingy) I learned that the output gets displayed on the glass/plastic plate ( in the case of the calc I was peeking in, it was glass).

Furthermore, the backplate of the screen (the grey-metalish plate thingy) was loose from the glass plate, which allowed me to simply cut some paper in the right size, paste it in, and voila, the display was black on white, which looked a lot better and clearer than before. I don't get why they don't make all those plates white, it's waay more clear. You actually get the screen quality of an emulator this way.

Anyways, IF the backplate of a TI screen is also separate(able), you could place a piece of glow-paper between it and, yh, there you'd have your own backlighted calc, with not too much of a hassle to assemble, and not draining your batteries...


Quick made drawing to clarify the idea (it's paint-crap)

how do you mean? the foil is placed behind the display, so the output would always be seeable :]

about the lamp thing. A christmas light already uses 'much' energy to be bright enough, dunno if the I/O could handle that, and it would use some battery power. It might be doable with a led but idunno it handy tho. At least, I didn't rly like the lamp-things they were selling with the old GBC's.
EDIT: if you would need to run an app for light, you wouldn't be able to run anything else at the same moment?

neither do I atm, I'm going to buy an extra one for about 25 tho, so I might screw a bit with that one
Anyway, people have screwed so much with them, someone should know if the 2 plates are separate or not

Hmm, this (or the white paper) I could see myself doing.  It depends if I can find a cheap calc and decide that I'm good enough to not mess anything up.

mhmm interesting...

I wonder if this is scam or legit, though, we never know with websites

Else, another thing you can do is this

Of course, but it was still kinda funny back then

yeah it is fake hence the red outline signaling joke but imagine doing that to a ti-84 that would be epic

*lol, you would be in greyscale

lol, that's funny!
