Is it possible to download 'ndless and the gameboy emulator on the ti nspire cas?

I have attempted to download the emualtor for the gameboy on my ti nspire cas. But it did not work, i'm pretty sure it won't work, because in the readme file it said they only tested it on the ti nspire.

TI-connect for calculator

I'm having trouble loading "TI-connect" on my mac so that I can write programs for the ti-84 on the computer. After downloading ti-connect, I click on it, and it seems to want to install it again. I've done the complete loop, repeating the download process about 4 times.  Do any of you know what to do?

Building probe/sensor for TI Nspire CX CAS?

My TI Nspire CX CAS just arrived in the mail today!  It's an upgrade from a TI84, and my reliable old TI82.  Just a quick search yields a lot of information on how this calculator can be used as much more than a graphing calc. There is software available for scientific use, which incorporates specially designed probes to measure everything from sound to pH levels.  One that caught my eye as a possible diy project was a microphone.  It appears that there is an application that is capable of measuring and mapping sound waves.  An interfacing microphone.  Can't be too difficult, can it? As soon as it arrived, I popped on to Instructables and did searches for anything Nspire CX related, but received the dreaded "no results found".  I'll have to get to work.  Does anyone have any experience with this calculator or it's data functionality? Thanks!

Old TI-85 Uses

I just got a TI-85 at a yard sale for a dollar. I already have a TI-84, so I have no need for it for school. Any ideas on what I use it for? Can I take it apart , build anything with it? Here are the specs: http://en.wikipedia.org/wiki/TI-85#Technical_specifications. It has a Zilog 800 cpu

Using precalculus to write a TI-84 program

Hello everyone, I am in a precalculus class, and I am attempting to do a project on practical application. The majority of students use the TI-84 for various math courses.  They are also available in the library to rent.  Unfortunately, few students take the time to actually use this wonderful tool.  I would like to create a web-type video that can be posted on the course's forums, giving a demonstration on creating simple TI-84 programs that could be used to make life a little easier.  Take a concept out of the book, and demonstrate the practical use. Most of my hobby activity involves electronics of some sort.  I have a bad habit of explaining things far too technically.  I have difficulty explaining things in simple terms.  My goal with this project is to learn how to explain concepts in terms others can understand, and possibly to help someone else learn. After many scrapped ideas and half written programs, I was thinking of writing a simple program that calculated the maximum number of lightbulbs that could be safely connected to a 15 Amp breaker.  I suppose it would be easy enough to allow the rating of the breaker to be a variable, but first things first.  Don't want to get too advanced before I have a clear working model.  Can anyone suggest another role that functions play in our every day electrical/electronic life? Many thanks.

Is there a way to hook up a Ti-84 to my cell phone? Answered

I want to hook up a Ti-84 to my PPC-6700. i was wondering if first if this is possible and second if this is a "good" way to get programs on to it... don't ask me why i cant just hook them up to my computer... i will just say that i cant. the way it would most likely work is through both of the usb ports... (one on each device).

TI-84 program for simpifying radicals into a form like number plus rad(9) ?

I already have a program that simplifies radicals but dont feel like adding on a feature to take in consideration of things being added to it or subtracted from it. Anyone know of a site that has the source for a program like that, if not i guess i will just have to do it myself.

Soldering a TRS to TRS cable?

I am trying to make a transfer cable for my TI-84 Plus Silver Edition Calculator. It came with a USB-mini to USB-mini cable, but it has two ports on top. One for a USB-mini cable, and one for an I/O cable, with 3/32 TRS jacks (2.5mm) from Radio Shack. I am wondering how to connect two TRS jacks together to make a transfer cable. I don't know what kind of wire to use, or how the wires should be connected.

Calculator IM

At my school we are required to have these TI-83 plus calculators for math. Of course we have classic games and stuff that we put on there, but we want to try to put an infrared emitter and detector on it so we could send IM's within the room to each other. Kinda like texting. Could anyone help us by suggesting ways to do this?

Calculator Programs for Math

I've been working on some programs for my calculator recently and have decided to share them. I made these myself from scratch. If you want to modify go ahead just credit me. Don't sell them. And don't use them in math class if your teacher says not to. The programs are a follows: a quadratic formula solver, parabola solver, slope of a linear equation finder, and y-intercept finder. The programs work on TI-83's and TI-84's. If you have questions on how to use them or how to put them on your calculator please leave a comment!
