Still depends on the sort of game tho..

it would most likely just screw any magnetic part of your calc, then melt it, let the time battery explode and let you die in 7 days, when you eventually will have a grey* skin, no hair, no nails and maybe not even eyes...

*lol, you would be in greyscale

no thanks, i'm happy with 2 arms

well, it seems like you only have to screw your calc open, pull your disp a bit back, use ether-ish fluid (that does not screw plastic) to separate the transparant piece from the metal, cut a piece of glow-in-the-dark-tape/paper, put it between the 2 plates, close everything and done O:
+ remove batteries before working and ground yourself before you start working, just like when working with any other computer device ;]

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?

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)

Omg, this is awesome O:
I love it

Not rly from #omnimaga but we were both at it on that moment
One of our rather philosophical conversations during this summer xD

[22:27]   <TsukasaZX>   "According to some, every possible outcome that can occur has occured in a parallel reality. I like that idea. Why? Because it means that in an infinite number of universes, I am Batman."
[22:28]   <_NF_>   
   <TsukasaZX>   This is why I don't completely disregard science
   <_NF_>   lol
[22:29]   <TsukasaZX>   And in one universe, we're ALL Batman :O
[22:30]   a universe of batmans.... sounds very emo
   <_NF_>   lol
[22:31]   in one universe I have morals and a good working TI84+ and you have a girl and drink beer like an alcoholicus and all the Omnimaga members are living in one city!
   <TsukasaZX>   creepy....
[22:32]   <_NF_>   lol :p
[22:33]   which part, me having morals or all living in the same city
   <TsukasaZX>   in some universe, we're both geniuses
   and yes
[22:34]   *shudder*, in one universe, pants were never invented....
   <_NF_>   in one universe we are master C++ programmers and calc84 is a dehydratated cactus on my desk 0:<
   <TsukasaZX>   
   LOL!
   <_NF_>   
   <TsukasaZX>   in some universe, you're a girl.... creepy
   <_NF_>   
[22:37]   in some universe, there is no 4chan :O
[22:38]   <_NF_>   i don't go to 4chan
   
[22:39]   <TsukasaZX>   there's really no point to it. I wanna live in that universe that doesn't have it :O
   <_NF_>   :p
   <TsukasaZX>   it only exists for porn and origami
[22:40]   <_NF_>   in one universe, they have combined both
   o.o
   <TsukasaZX>   Pornigami? O_o
   <_NF_>   OMG!
   xD
[22:41]   <TsukasaZX>   that sounds like a section of the kama sutra
   <_NF_>   hope u don't get a papercut
   
   <TsukasaZX>   lol

extra; I did not want to offend calc84maniac, I just mean I'm jalous at him for his überskillz ^^
