![]() Output pretty-printing: while not as nice as the one done by the OS on built-in math screens, this still is much better than what you get with most Eigenmath ports:īracket color-matching on command input (like the OS does) Ģ00 lines of console scrollback and 40 command history entries In addition to this, there are also some features exclusive to this port, some of which only make sense to include with the Prizm platform: Script execution and creation ("recording") įunction catalog (with help for each function). Graph plotting (zoom in and out, move left/right/up/down as with the OS) Some features from the graphical versions and ports of Eigenmath are also available, with different UI (adequate to the platform), including: This means certain commands are going to take longer to execute, and certain ones won't complete due to lack of memory (640K ought to be enough for anybody, as if it's 1981 again). ![]() FeaturesĪll of the functionality of the command-line version of Eigenmath is available on this port, with limitations consistent with the technical limits of the Casio Prizm platform. This is a port of the Eigenmath math engine to the Casio Prizm in the form of an add-in, providing numerous math functions not available in the OS, including symbolic computation.

The project page doesn’t mention any games yet, but we’re sure it won’t take long before someone ports Tetris to this system as well. Thanks to the flexibility of MicroPython and the ESP’s WiFi system, the Galdeano is not limited to implementing a calculator: it can also perform various general-purpose tasks ranging from file editing to controlling a set of smart light bulbs. ![]() Porting Eigenmath to a memory-constrained platform like the ESP32 was quite a challenge and required a few workarounds, including a memory partition scheme and even a custom compact font with mathematical symbols. This enables the Galdeano to manipulate expressions, perform integration and differentiation, and plot functions. The ESP32 runs MicroPython along with a symbolic math engine called Eigenmath. The entire thing is housed in a 3D printed enclosure with color-coded buttons indicating various built-in functions. It can be powered through a lithium-polymer battery or, like a classic calculator, through four AAA cells. The heart of the device is an ESP32, which sits on a custom PCB that also holds a 6×7 array of push-buttons and a 320×240 touch-sensitive color display. The worst thing a lazy student can do is play a simple game like Snake or Tetris.īut what if you’re not a student anymore and you want a graphing calculator that has up-to-date hardware and infinite customizability in software? Look no further than ’s Galdeano, a handheld that has all the features of a modern graphing calculator plus a lot more. Even though teenagers nowadays carry powerful internet-connected computers in their pockets, math teachers often prefer them to use a clunky Z80-powered calculator in class, if only because their limited performance reduces the potential for distraction. Graphing calculators have evolved from expensive playthings for rich nerds to everyday tools for high schoolers worldwide. ![]()
