Less than seven years late, Cemetech's calculator-hacking exhibits at World Maker Faire 2018 - and what the loss of the Faire in 2019 has meant for showing off DIY, making, and hacking, inside and outside the calculator community. www.cemetech.net/news/2025/7/...

Our members were unusually busy in May, with 8 completed projects to vote on, and many others moving forward. Check out arcade and 3D calculator games, a Godot game, hardware projects, and yes, even a few math projects: www.cemetech.net/news/2025/7/...

I've been writing 3D graphing programs for assorted graphing calculators since at least 2003. Now, after starting a 3D grapher for the TI-84 Plus CE and then pausing for eight years (coincidentally roughly the time since @geopipe.ai was founded), I've released it: www.cemetech.net/forum/viewto...

What do a dithered puppy, row-major LCD graphics routines, and an update to a 29-year-old black-and-white arcade game have in common? They're all projects in Cemetech's April Projects of the Month update: www.cemetech.net/news/2025/5/...

Even better - a math corgi puppy.

Unfortunately, we didn't find a solution.

Better late than never: March 2025's hobby STEM projects on Cemetech covered the usual gamut, from games to an emulator to a MIDI player. Check them out, and vote for the best! www.cemetech.net/news/2025/5/...

Your mission, should you choose to accept it: vote for your favorite Cemetech graphing calculator software project of 2024: www.cemetech.net/news/2025/1/... . You have plenty of options, including games, programming tools, math apps, and shells.

Using Chrome "fixed" the issue, but the Firefox problem persists, even when pasting the image into the post.

2024 ended strong: Cemetechians worked on calculator, computer, and hardware projects in December 2024, from an on-calculator ez80 ASM IDE to math and 3D graphing tools to a TI-84 Plus-turned-art. See them all and vote for your favorite: www.cemetech.net/news/2025/1/...

Any image we upload to a Bluesky post from Firefox seems to turn fully black, whether JPG or PNG. Any workarounds/is this a known issue?

If you feel like we just posted a Projects of the Month, you're not wrong - but Cemetech's news editors were efficient with November 2024. Projects included games, math tools, a physics simulation, and even a shockingly powerful 3D renderer. November's projects: www.cemetech.net/news/2024/12...

Another month, another Projects of the Month! Cemetechians worked on games (arcade games, RPG games, Cookie Clicker), hardware projects, a hex editor, a 3D grapher, and more in October: www.cemetech.net/news/2024/11... #z80 #ez80 #diy #hacking

Cemetech's Minecraft 1.21+ survival server will be launching tomorrow, October 12th, at mc.cemetech.net. Come explore and build bases, cities, and machines with Cemetech! www.cemetech.net/news/2024/10...

Do you need three sprite/icon editors, an ez80 assembly IDE, Sonic 2, or OCaml on your graphing calculator? These and many other projects are in Cemetech's September Projects of the Month: www.cemetech.net/news/2024/10...

The Casio fx-CG100 has been announced by Casio Education. Now part of the ClassWiz line, it's sleeker, but early reports suggest Casio BASIC and C programmability may have been removed. More when we get hands-on: www.cemetech.net/news/2024/9/... #edtech

Did you see what Cemetech's members made in August? From a base converter to a calculator-themed arcade fighting game, sidescrollers to an icon editor, programming references to train simulation rigs, see 'em all here: www.cemetech.net/news/2024/9/...

Another Projects of the Month: Cemetech's programmers worked on impressive graphing calculator and computer software in July. Check 'em out: www.cemetech.net/news/2024/8/...

Think you're a TI-BASIC expert? Cemetech admin iPhoenix has posted a TI-BASIC brain-teaser you can solve with some out-of-the-box thinking on how the TI-BASIC parser works: www.cemetech.net/forum/viewto...

What graphing calculator should you buy for school? A TI-84 Plus CE, TI-Nspire CX, HP Prime, Casio Prizm, or something else? Whether you're a parent or stude... BEST and WORST Graphing Calculators: Back to School 2024 Guide

It has been two years since I last posted one of these: if you (or your kid) needs a graphing calculator this year, here's what I recommend: www.youtube.com/watch?v=E_wa... #calculator #backtoschool #edtech

Cemetech's members created games, utilities, hardware projects, and more this June! From a solar-powered TI-84 Plus to Quantum chess and Minesweeper for the TI-84 Plus CE, check out their creations: www.cemetech.net/news/2024/7/...

Another month, another Projects of the Month. Check out the #games, shells, libraries, and hardware projects for graphing calculators (and beyond) that Cemetechians worked on in April 2024: www.cemetech.net/news/2024/5/... #edtech

End-Of-Life For Z80 CPU And Peripherals Announced In a Product Change Notification (PCN) published on April 15, Zilog (now owned by Littelfuse) announced the End of Life for a range of Z80 products, specifically virtually all of the Z84C00 range. …

Have you seen that Zilog is discontinuing the venerable #z80 CPU? The ez80 and friends will still be around, but the CPU that spawned countless computers (and graphing calculators) will no longer be made. hackaday.com/2024/04/19/e...

And finally, the Projects of the Year 2023! Cemetechians loved Celtic CE, a port of the library that lets TI-BASIC programmers do more, plus an audio/video player for the monochrome calculators and the addicting Wordle spinoff "Topicle": www.cemetech.net/news/2024/1/...

The votes are in! CEaShell won our Project of the Year 2022, followed closely by AnotherWorldCE and S.A.M.M. - A Metroid-vania for TI-84 Plus CE. www.cemetech.net/news/2024/1/...
