Calcsy – See your calculator on your computer

Filed under: Education, Math, Programming, School, Technology — Andy @ 9:17 pm

Calcsy LogoCalcsy is a tool you can download and use on your computer to show (and save) the screen of your TI-84+ or TI-89 Titanium calculator.

It’s useful for projecting the screen large enough for other people to see, or for taking a screenshot to use in instructions. For example, I’ve used it in teaching how to graph functions on a calculator, and I suspect it will be similarly useful to other people.

I first wrote Calcsy almost two years ago, and have been (very) slowly making it better since then. It’s now to a state where I think it’s reasonable to release. At the moment, it’s only available for Mac OS X, although it should be possible to port to Windows if there’s enough demand. Hopefully it’s pretty self-explanatory, but feel free to let me know if you have any questions.

All you need is a TI-84+ (or TI-84+ Silver Edition) or TI-89 Titanium and a USB cable to plug it in to your computer. The program is free, and you don’t need any special software on your calculator. (You also don’t need one of the special “Presentation Link” adapters – your computer and a normal USB cable works just fine.)

Other details of note: I suspect it won’t work with the very new TI-84+ Color calculators, but I’m happy to try to make it work if someone wants to send me one. Also, the logo was made by David Felice, so thanks are due to him.

Anyway, it’s free, go check it out. Let me know if you have any questions/comments/problems/etc.
