Re: TI-H: TI-Indiglo
Yes, we are well aware of the fact that works, but Indiglo is brighter, and
looks cooler. Plus, we all want to find a real use for EL panels in ti calcs

Subject: TI-H: TI-Indiglo
For all of you who have been e-mailing back and forth about Indiglo on a
calc. I have the perfect solution. I went to my grandfather's house and
had him cut a piece of plexiglass about 1.5mm thick. Then I sand-papered
the sides enough to reflect light. I bought 8 high-brightness LEDs from
DIGI-Key. I set them up in a seriex-parallel circuit with a small trimmer
sticking out of the side of the calc (for brigthness). I CAREFULLY removed
the LCD and put the plexiglass between the mirror and the LCD screen. I
then placed the LEDs around the edges so they were touching the plexiglass
and glued them in. I put everything back together, and it worked. Good
luck if you try it.
