- Duck Life Live Duck Renderer for the TI-84+ CE: As a part of a future Duck Life port, slimefolf made a demo program which renders the game's duck character using simple shapes from the graphx library. They've also published the source code for anyone interested in using the code or taking a look at the rendering system behind the scenes.
- Emulator without a name.: ti_kid started work on a TI-83/84 Plus emulator this month. They plan on making an initial version for PC and then eventually porting it to the TI-84 Plus CE. After an unfortunate loss of data, they restarted the project later in the month, this time making use of the CE's Z80 mode.

- lwIP Library with CDC-Ethernet for the TI-84+ CE: Using an x25519 algorithm written by PT_, ACagliano is now in a good spot to finish implementing the TLS 1.3 client-side. They also reworked the ASN.1 parser system and split the keyobject module into pksc8 and x509 modules.
- matrix, Step by Step Linear Algebra for the TI-84 Plus CE: Using their LaTeX engine, sightem created a linear algebra program for the TI-84 Plus CE which can perform a number of different operations while showing the answer step by step so you can follow along.
- password protected game/chat/game launcher program: Liam P started work on a multi-use TI-BASIC game launcher, that includes a few different games to play against the calculator and requires a password to access. In the future, they plan on adding more games along with a "facts" feature.

While an ambitious project, they’ve already made some solid progress on menus and a title screen during February.
- TI84+ CE Notes App Generator, formatted math and text: In another project demoing their LaTeX rendering engine, sightem created a simple notes app generator which can be used to create nicely formatted notes that can be downloaded and viewed on your calculator. The project can be built with GitHub Actions and requires no local setup, making creating your own notes quite convenient.
