A new Exploring Uncut post where I write about my progress with implementing a Mandelbrot set on an STM32 board: some surprises and learnings to get the FPU working with , learning about call-clobbered vs callee-saved registers and using ChatGPT not for vibe coding but as a debugging and learning tool.

Exploring Uncut - March 3rd, 2026

Introduction This time, the focus is solely on providing an update on my exploration of getting a Mandelbrot set renderer running on an STM32F746G-DISCO board. I had hoped to also cover “The Egg Project” and some Home Assistant improvements I’ve been working on. However, there is already plenty to discuss here, and the other projects have been moving forward more slowly due to a collection of minor but frustrating issues, from ordering the wrong components, to chasing down unexpected sensor behavior, to tracking a Wi-Fi authentication failure caused by a simple case mismatch.
