I spent a three-day train ride across the country adding support for @ticalculators.bsky.social's newest graphing calculator to Cemetech's web-based IDE, SourceCoder 3. View, edit, and export TI-BASIC programs (and other files) for the TI-84 Evo in your browser. www.cemetech.net/news/2026/5/...

Coming soon: TI-84 Evo support in SourceCoder 3, so you can created and edit Evo programs, variables, and images right on your computer.

The TI-84 Evo is here. An ARM Cortex-driven calculator in seven colors, running at 156MHz with double the storage of the TI-84 Plus CE, it appears to have a significantly redesigned OS that retains keypress compatibility with 30 years of TI-83/TI-84 Plus calcs.

The Youtube video has been since taken down for now, but TI-Planet admin critor grabbed it first. We're looking forward to putting TI's new TI-84 Evo through its paces at the beginning of May to see if it's truly an improvement on one of our favorite calculators. www.cemetech.net/forum/viewto...

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 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: www.cemetech.net/news/2026/1/...

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/...

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.

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
