The Ultimate Calculator

The Ultimate Calculator is an extreme-modded TI-83+ graphing calculator, a device with an MSRP of around $90. Almost everyone who has recently taken a high school or college math or science course should have at least a passing familiarity with it. It's a project I had dreamed of attempting for a very long time, but never quite had the resources and equipment to complete. At long last, it has been created, and all within the short span of a bit over a month. Firstly, to avoid a TL;DR situation, the headline features:
  • Modified LCD with RGB LED backlight controlled by a GAL16V PLD slaved to two CPU I/O lines allowing full-spectrum color control that also illuminate the case windows
  • Sanded, painted, and varnished case with sports car-style racing stripes
  • Removed LCD bevel and slanted LCD for more unique, non-branded look and easier LCD viewing
  • Internal powered PS/2 port with working drivers for use with external keyboards and mice
  • Case cutouts and case windows for added "wow" factor
