Today’s students are more likely to have a TI or Casio calculator, but HP is still in there with the HP Prime. The slide rule sword gave way to calculators hanging from your belt loop, and for many engineers that calculator was from HP. Well, really it was a slide rule hanging from your belt, but it sounds cooler to call it a sword. The keys on the Key-Log editor screen as well as the emulator LCD screen contents can beThere was a time when being an engineering student meant you had a sword. Windows only You can record key operations you perform on the emulator as Key-Log records, and edit Key-Log records as required. Fx-CG Manager PLUS is an emulator that lets you perform fx-CG10/fx-CG20/fx-CG20 CN operations on your computer.This emulator is a free online version of the NumWorks graphing calculator. FX-ES Plus Interactive whiteboard emulator for Casio Scientific Calculators Many teachers have asked for the facility to project their classroom calculators and this exciting new emulator from Casio really fits the bill Use this software for teaching on your Interactive. But still, it will run under Wine with no more than the usual amount of coaxing.Graphic calculators made by Casio include the touchscreen ClassPad 300 as well as the models with traditional buttons which can be divided into two main generations listed below.Casio produced the worlds first graphing calculator, the fx-7000G.- Windows Vista® and Mac® operating system 10.4 and 10.5 compatible. Of course, that’s free as in no charge, not free as in open source. To start with, HP has a free app that runs on Windows or Mac that works just like the calculator. But if you can’t justify a $150 calculator, there are some cheap and even free options out there to get the experience.Other applications include plotting, statistics, solvers, and even a spreadsheet that can hold up to 10,000 rows and 676 columns. It is also programmable using a special HP language that is sort of like Basic or Pascal. It also has an amazing number of applications including a complete symbolic math system based on xCAS/Giac. However, the HP Prime isn’t just your 1980s vintage calculator. Screenshot.You might wonder why you need a calculator on your computer, and perhaps you don’t.On iOS the cost right now is $25 and on Android it is $20. They aren’t free, but they are relatively inexpensive. However, you can also get official apps for Android and iOS.
The PC and phone versions will also connect just like a real device. For example, there is an application, HP Connectivity Kit, that lets you talk to a real calculator over the network. So this isn’t a case of someone just writing a pretend calculator, these apps act like the real calculator because it is running the same source code. Calculators have that feel to them. Telephone answering machines gave way to voicemail. Cassettes gave way to CDs and then CDs gave way to digital music. There’s also been the inevitable hacking of the communication protocol.History is replete with products that seemed amazing for their day but turned out to be just a stopgap for something better. :) Here I am now, with my HP-16C in front of me. Not all homemade calculators are simple.Posted in Hackaday Columns, Slider, Tool Hacks Tagged calculator, hp prime Post navigationI guess you meant the HP-16C. And a calculator still makes a nice project. You can only wonder if it will be the last great calculator, or if there are more yet to come. But it’s buttons are crap, it’s display is LED, tiny and dim, and the HP-16C can just do a hundred things more than the TI programmer.The great thing about the HP-16C is the layout of it’s keyboard. It’s also kind of useful, it can convert dec/hex/oct, and do some logic operations, and can shift bits. I even ported over the ‘nonpareil’ emulator to iOS to be able to always have it with me on my iPhone (for personal use only of course :)).I also have a TI Programmer. Never had a better calculator/computer for software development work. I suppose that shiny new graphing calculators probably have better screens than I grew up with. It’s much easier to type on than either the app in normal mode or as I remember it my actual physical HP48G was! It takes two physical calculators to get that.Or maybe you are using all those wonderful graphing abilities. The recovered space is used by making the keys bigger. Unfortunately haven’t had a reason to graph anything lately so I just double-checked to make sure I wasn’t posting misinformation. That’s a lot of area for the graph. I could have sworn however that Droid48 had a feature where you could hide the keyboard, all except the arrow and function keys and expand the display to use most of the screen. Graphics Calculator Emulator Casio Skin Where TheVery few people in college will be academically impressed by a student who can mentally easily factor polynomials mentally, but in high school that is still an important skill to build up and so having a CAS which can either do that or be used to automate the process easily to someone who is good at programming is not good as it could mask students with legitimately rare mathematical talents from those who are just familiar with software engineering fundamentals. They provide physical keys are efficient and error free input and low power consumption and reliability which are key for testing systems that cannot tolerate the single digit percentage IT issues of computers.Also, the limited mathematical capabilities provides focus and a level playing field for the topics explored by the student. Just make a skin where the screen is nothing but display and use the keyboard for everything.I think calculators are still fundamentally important for education. And besides, if I ever wanted to do any large amount of typing on my “calculator” I could always get a bluetooth keyboard or even plug in a full-sized USB desktop keyboard via USB-C.If a person REALLY did a LOT of calculating I could even see building a dedicated calculator with a Pi, an LCD and a full-sized keyboard. Maybe it’s skin dependent or maybe I used to have a different emulator app.Anyway, the minimal keyboard option is pretty great and even with all the keys showing on my S9 the buttons are bigger than the physical buttons on any calculator I have ever seen. I can’t find that feature today. About 4x what was actually being used). 2^14 didn’t work) Or requiring independent heap objects for every element of the array, preventing efficient arrays of ints, or any other numeric (In testing it used ~16 bytes per int element in an array iirc. Things such as hard limited max array lengths of ~9999/10k (I think, I stuck to using 2^13 as my cap for sanity and efficiencies sake. Likewise, hacker types who may be struggling at really understanding analytic geometry even though they can tell their computer to do vector math for them might need to stay after class a bit to brush up, and shouldn’t let their computer mask that need.I wouldn’t mind their choice of language so much if their twist on it didn’t have so many bugs and inefficiencies.
