Hi Omnimagas!
« on: March 23, 2015, 12:54:48 pm »
Hello,
I like the calculators for higher classes like TI Voyage, Casio Classpad und others like this. After some playing with them I got now an older Nspire Clickpad CAS. Same pain as with the other calculators: the display is ever much to dark. So i am trying with thick cables to get LED light to it from above. It looks not so good but it works. If I find a more stabile solution I may tell it. Now looking for hints for programming in Lua.

Heya, welcome to Omnimaga! Lua is a pretty neat language, hehe (I don't have an nspire, though <_<)
Also, the LED backlight for the calculator screen sounds like an awesome idea!

Anyways, have some peanuts:

Welcome to the site! Always nice to see fresh meat newcomers, especially considering this isn't the most active forum on the internet  ;D
Also, you can never have enough peanuts!

Oh, that's a kindly welcome. Thanks for this and some hints and links. Up to now I have not the impression that it is easy to find the Lua tutorials/manuals that I just need. Some infos here, some there, some examples that work, some doesn't (a beginner tut, made on ti software emu and using steadily the print command. Needed some time to understand, why this does nothing on nspire...). Maybe it's better to buy the programming book from iesus... jessas... one of the brazilian Lua founders, but v. 3 is rather expensive. So I am still trying, searching here and otherwhere.

The old light problem of the displays...  my working version is not bad, but I will present it when I can say that it's easy to make for everyone, cheap and as solid as it has to be for daily usage (at this time the main con to my construction). Am just going on from thick cables to plastic as led holder.

The "Print" command prints information to the console, so it's useless on calc unless you're in an on calc script editor, and is mainly useful for debugging. The tutorials I sent you are pretty complete, feel free to make a post if you have any questions. Good luck ^.^

I side-lit one of my calcs.  Works ok, but the contrast has to be pretty high.

I got the best contrast by putting led on upside to an angle, that is close to see the led reflecting at lcd. The distance may be about 20-25 cm, the led I use are any of the newer that gives already much light at a current around 8-12 mA. All tries with close led at the lcd gave bad contrast at the Nspire, also with several leds and higher current. My main thing is still the construction of a mechanism that can be removed, when it's not needed.
The best solution I had (Lowe shortwave receiver) was demounting the lcd, removing the foil at backside cautionly and putting a milk glass like foil and a led stripe from a lighted lcd at backside. Whoever likes to try this with a Nspire? IoI
