Cemetechians have spotted more photos and marketing materials about the new TI-84 Evo calculator, reportedly coming at the end of this month: www.cemetech.net/forum/viewto...

The results for our 2025 Projects of the Year are in! Screensaver CE gets the gold medal for classic and new screensavers on your TI calculator, while a graphics library, an HP Prime Tetris game, and a flamethrower with an embedded calculator join it on the podium. www.cemetech.net/news/2026/3/...

Fifteen DIY coding/hacking projects won or tied as "Projects of the Month" on Cemetech in 2025: now it's time to choose the best of the best. Games, screensavers, utilities, and a calculator flamethrower await: www.cemetech.net/news/2026/3/...

NEW TI Calculator Discovered: TI-84 Evo YouTube video by KermMartian

Here's (almost) everything we know about the new TI-84 Evo calculator from Texas Instruments (3x faster CPU, more storage, new UI...): youtu.be/EsLICWjasoo

New info on the upcoming TI-84 Plus Evo graphing calculator, thanks to MateoConLechuga: USB-C, 3.5MB Flash storage, a smoother font, wider graphing, and a possible change to the TI Innovator accessories making them incompatible with the TI-84 Plus CE. Discussion: www.cemetech.net/forum/viewto...

Eleven years after the TI-84 Plus CE, the color screen version of the immortal TI-84 Plus calculator, @ticalculators.bsky.social will likely be releasing the TI-84 Evo. Leaks point to UI upgrades mirroring Casio and HP calcs, 3x faster CPU, and rearranged buttons. www.cemetech.net/news/2026/1/...

Our last Projects of the Month for 2025 includes an HP Prime turtle graphics port, a voxel MMO, a variety of TI-BASIC arcade-style games, a TI-Nspire CoD Zombies "demake", a train simulator, and much more. Vote to choose the last contender for Project of the Year:

This is the most @cemetech.net coded post I’ve ever seen on here

Do you like flying toasters, word games, crossword puzzles, or building operating systems for 8-bit CPUs? If so, November's Projects of the Month at Cemetech have you covered: www.cemetech.net/news/2025/12...

Floppy Drive Music with a Calculator YouTube video by KermMartian

Bought I guess in some sense I “used” a floppy disk when @kermmartian.z80.me brought FloppyTunes to the @cemetech.net maker faire booth circa 2015 youtu.be/WePVjW98t5A?...

Arcade games galore, and more: Projects of the Month for October 2025 is here, with calculator and computer games (and beyond): www.cemetech.net/news/2025/11...

What do shells, roguelikes, 3D Github contribution visualization, text editors, and arcade games have in common? They're all featured in our September 2025 Projects of the Month: for graphing calculators and computers: www.cemetech.net/news/2025/11...

We woke up just before September ends: our August 2025 Projects of the Month is live. Tetrises, RPGs, hardware projects, for graphing calculators and beyond: see what our creative hobbyists have been making, and vote for the best: www.cemetech.net/news/2025/9/...

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/...
