Casio Scientific Calculator Emulator

The original code is given a chance to run one of its very unique bit instructions that contained both the operand and the address of the next instruction. The decimal point is in a fixed spot as storing numbers in a scientific format simplifies both internal calculations and displaying the result. If anyone would like the modified version, let me know. This is the first published version for Windows Phone, so hopefully new versions will round out all the functions. It is very interesting seeing the intermediate results the calculator goes thru before arriving at an answer.

The chip is already preprogrammed - thank You. This is powered by an Arduino Nano. Join our mailing list and stay updated about pioneering hardware and Tindie community activities. Implementing all of those functions was not without cost.

Apple got itself into hot water recently for getting too deep into skeumorphism, i. Square root This calculator allows you to define your own functions to use in expressions. Reverse Polish Notation was used as it simplifies the processing of the operands.

Very nice kit, simple assembly with no problems. Use parenthesis to alter the order of operations or to specify function parameters.

Results are displayed as fractions when possible, as well as in their floating point approximation. The emuloator does not seem to care about the other bytes in the file. This calculator gives fun on party. All you really need is basic soldering skills and you can put this together in under an hour. There isn't a selection process or form to fill out.

Enter your expressions in the same order as you would write them on paper. Shipping Info No country selected, please add to cart to select your country and see shipping options. The creation of this calculator represents the triumph of the human spirit over the impossible. It was working on first time.

There is one option however, code execution speed. Decimal to fraction conversion Percentages Scatter plot Box plot. This is a formula calculator. We recognize our top users by making them a Tindarian.

You can also select to display the results in a different notation. The Arduino software is a very thin layer interfacing to the original code. If the calculator is powered up, it runs at the original speed and the display is blanked out while a result is being calculated, just like in the original hardware. Everything is included including batteries to power it up after you've finished. It does, but we are still in the early stages.

The connections from the keys to the display were reverse engineered by pushing two keys at a time on the original calculator and seeing which two digits in the display were affected. You can type your expressions directly in the calculator input field or use the online keyboard. Fully assembled - gets you a working tested calculator.

Hi Tuyen, can you please send me the modified version. Only thing I dislike is Power On switching in down direction. The normalize function can be seen working on the slowest setting. See calculator notation for more information. Simple numeric and scientific calculations go smoothly, but there's quite a lot missing once you start straying into the esoteric here.

They should've gotten a graphic artist to fix it before they implemented it into the program and released it. Arduino Nano is pre-programmed. The image is now perfectly balanced with the right amount of brightness and contrast.

Fun and faithful reproduction of original device I miss my old Sinclair calculator but this is the best best thing. Options Kit - gets you all the parts needed to assemble the calculator. The emulator is executing the actual instructions that ran on the calculator.


You can write low level programs without any problem. If Develop Studios are reading this then get in touch and I'll add it - you could do with some beta testers!

The Casios are for the more intelligent people who can figure out things themselves, band logo maker since Casio does not provide any documentation about hardware. Also it seems unlikely that casio puts infected files on casio official download server. The source code is open and you can learn a lot poking around the very elegant small code base that makes the Arduino Nano emulate a vintage Sinclair Scientific Calculator. The hardware portion of this project is now an accurate recreation of the Sinclair Scientific Calculator circuitry. For help refer to the Instruction manual and to the Online Scientific Calculator blog entries.
