The SD card on your ILI9488 won't init? Stop fighting the SPI bus.
I spent days on this. The ILI9488 display worked perfectly, but the SD card slot on the same module refused to initialize. Shared SPI, MISO conflicts, CS timing—nothing solved it cleanly.
Then I stopped trying to make the SD card work.
The fix: I converted the image into a C array, embedded it directly into the ESP32's flash memory, and drew it straight to the display. No SD card. No file system. No bus conflict.
The display now shows the image every time, instantly.
This is the reality of embedded work. The datasheet says one thing, the hardware says another, and the deadline doesn't care. You don't always fix the original problem—you find the path that actually ships.
If your embedded system is stuck in a fight with its own hardware, that's the kind of problem I solve.

A small experiment with a more cinematic AI video.
30 seconds, one story, one prompt: a girl crosses a ruined city to find medicine for her younger sister. The ending doesn’t go exactly as planned.
The goal here was not just action, but:
realistic cinematography, tension, clear storytelling, and an emotional ending.
What do you think about this format?
The eyeball cursor over the massive iris type is such a fun interaction idea. Pushing the type and cursor this far on a fake AI lab page is exactly the kind of play that builds real skill.
WIP, not showing the animation yet, just how it’s built. Clean keyframes, no shortcuts... Final piece drops soon.
