2022 Cyberdeck Contest: The Galdeano is More Than a Graphing Calculator

A graphing calculator with a 3D-printed enclosure, with a circuit board next to it

Graphing calculators have evolved from expensive playthings for rich nerds to everyday tools for high schoolers worldwide. Even though teenagers nowadays carry powerful internet-connected computers in their pockets, math teachers …read more Continue reading 2022 Cyberdeck Contest: The Galdeano is More Than a Graphing Calculator

Scientific Calculator Whipped Up In Python

Scientific calculators were invaluable to most of us through high school and college, freeing us from the yoke of using tables to calculate logarithms and trigonometric functions. Once out in the real world, it’s no longer necessary to use an education board approved device to do your maths – you …read more

Broken HP-48 Calculator Reborn As Bluetooth Keyboard

Considering their hardware specification, graphing calculators surely feel like an anachronism in 2019. There are plenty of apps and other software available for that nowadays, and despite all preaching by our teachers, we actually do carry calculators with us every day. On the other hand, never underestimate the power of …read more

TI-83 Gets CircuitPython Upgrade

Graphing calculators are an interesting niche market these days. They’re relatively underpowered, and usually come with cheap, low resolution screens to boot. They remain viable almost solely due to their use in education and the fact that their limited connectivity makes them suitable for use in exams. The market is …read more

That TRS Jack On Your Graphing Calculator Does More Than You Think

It’s not Apple IIs, and it’s not Raspberry Pis. The most important computing platform for teaching kids programming is the Texas Instruments graphing calculator. These things have been around in one form or another for almost three decades, and for a lot of budding hackers out there, this was the first computer they owned and had complete access to.

As hacking graphing calculators is a favorite for Maker Faires, we were pleased to see Cemetech make it out to this year’s World Maker Faire in New York last weekend. They’re the main driving force behind turning these pocket computers with …read more

Open Source Calculator Teaches us about Quality Documentation

Graphing calculators are one of those funny markets that never seem to change. Standardized testing has created a primordial stew of regulatory capture in which ancient technology thrives at modern retail prices while changing little. The NumWorks calculator certainly isn’t the first competitor to challenge the Texas Instruments dynasty with a more modern interface (and a design from this decade), but behind it’s subtle color pops and elegant lines lies the real gem; a fantastically well documented piece of open source hardware. The last time we wrote about the NumWorks, it was to demonstrate a pretty wild hack that embedded …read more

Graphing Calculator Dual Boots With Pi Zero

The nearly limitless array of consumer gadgets hacker’s have shoved the Raspberry Pi into should really come as no surprise. The Pi is cheap, well documented, and in the case of the Pi Zero, incredibly compact. It’s like the thing is begging to get grafted into toys, game systems, or anything else that could use a penguin-flavored infusion.

But this particular project takes it to the next level. Rather than just cramming the Pi and a cheap LCD into his Numworks graphing calculator, [Zardam] integrated it into the device so well that you’d swear it was a feature from the …read more

Hackaday Links: September 3, 2017

The TI-83, TI-84, and TI-86 have been the standard graphing calculators in classrooms for two decades. This is the subject of an xkcd. Now, hopefully, there’s a contender for the throne. Numworks is a graphing calculator that looks like it was designed in at least 2006 (so very modern), and apparently, there’s a huge community behind it.

Juicero is shutting down. No one could have seen this one coming. The Juicero was a $700 press that turned proprietary, DRM’ed juice packs into juice and garbage. It was exquisitely engineered, but it turns out very few people want to spend thousands …read more
