Yes a battery should fit inside. Because the calculator the is a Ti-83 (witch is older an pretty fat) everything will fit along as you clean up the inside. I'm putting a Adafruit's 1200 mha battery but you could probably fit a bigger battery. If you take on this project Id love to see what improvements and how you design it.

Still working on configuring the screen. But here it is in action,https://www.youtube.com/watch?v=3Ct8L3GOR0Y.

Amazing project!

Only thing I can nit pick is the screen not taking up all the space it has, that looks a bit strange, oh well.

Yeah that's bugs me too. Unfortunately it was the only way I could get the screen to fit. I even tried cutting some of the extra pcb off the screen but it still ended up that way. I guess it's just something to work on my next attempt.

Looks good! Framerate looks a little choppy... Did you use moosepr's guide for getting spi screens to perform?

yeah that does look a little bit slow.

in your fbtft.config, change the speed to 80000000 and add in fps=60

Thanks for showing me this!! I also posted this on Reddit and people seemed to like it (https://www.reddit.com/r/raspberry_pi/c ... alculator/). I might possibly create a version 2.0 of this project, along with a tutorial if anyone is interested.
