The TI-84 Evo graphing calculator

The TI-84 Evo The TI-84 Evo is a next-generation graphing calculator featuring integrated Python programming, a 3x faster processor, and a USB-C port, designed to replace the TI-84 Plus CE Python. It includes an icon-based menu, a larger graphing area, and supports both Python and TI-Basic for coding. It is approved for major exams, including SAT, ACT, and AP.

It features an ARM Cortex CPU running at 156 MHz, delivering 3x faster performance than previous models, along with integrated Python programming via a USB-C port.

Includes built-in CircuitPython support, allowing users to write and run Python code directly on the calculator.

It acts as a successor to the TI-84 Plus CE Python which used a separate ARM Cortex M0 co-processor. It offers a faster, refined experience with a new icon-based user interface.

A broken bike sync led to reverse engineering Wahoo’s hidden debug mode

Noah Clements’ bike rides stopped syncing to his phone. That was it. That was the whole reason he ended up reverse engineering Bluetooth packets, decompiling an Android APK, and getting greeted with “WELCOME TO HELL DEVELOPER” on his cycling computer.

I ride a Wahoo ELEMNT Bolt v3. It’s a solid GPS cycling computer – maps, sensors, the works. But at some point my rides just stopped syncing to the companion app on my phone.

The Bolt v3 runs a custom Android build.

See how Noah dug through the code, found the developer menu and ended up documenting the full BLE protocol, the file transfer system, and more.
