TI-84 Evo support in SourceCoder 3 is here! Write TI-BASIC programs for TI's brand-new color-screen calculator directly in your web 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.

If you can't get your hands on enough graphing calculators, how about a LEGO version for your collection? beta.ideas.lego.com/product-idea...

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/...

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