Hmm just one thing: Be VERY careful when connecting anything to the Nspire dock port! If you accidentally touch the wrong pins, you can permanently damage the calculator by short-circuiting it or other stuff. This happened to some people who tried the sound programs.

Would I need to buy the cords and the white thing(I think that is some sort of voltage regulator, but I'm not sure) that are in the picture, or do they come with the Arduino? And I don't know what revision my calc is either. All I know is I got it in May this year.

That's not a voltage regulator, it's 3 jumper wires connected to an LED and some wires in heat shrink tubing. And don't worry about it. You're not going to blow out your calculator with 5v and 50mA

Edit: Okay so with that arduino information and this I can do it. I'll flash it when my calculator arrives, even if it doesn't need flashing. Mostly because there is not a tutorial anywhere on the internet to do this

The Arduino should shut off automatically when there's a short circuit so the Nspire won't be damaged, so you shouldn't have any problems, unless you put way more than 5V in your Arduino.

Also please don't double post (post twice in a row), there's the Modify button for that, thanks ^_^

Remember the day the walrus started to fly...

I finally cleared my sig after 4 years you're happy now?
This signature is ridiculously large you've been warned.

I managed to get a very nice CX off ebay for $90, the datestamp is P-0612E and it's running

So it will probably come with Boot2 3.1.
You don't need he RS232 thing - just send the 3.1 OS through USB.
