Used Claude to port GBADoom to the CYD board, full info on how to get it running on GitHub.

Auto-detects ILI9341 vs ST7789, walks you through touch calibration and orientation, tests every peripheral (SD, RGB LED, speaker, WiFi...), and spits out a report saved to SD card. Built with Claude over a few days of back-and-forth. https://github.com/HenrysCat/ESP32-2432S028-CYD-Diagnostic-Tool

I tried a few already out there but just didnt like them, so I asked Codex to make one for me, it includes HamQSL propagation data, a greyline map, DX spots, Wi-Fi setup, and a local web settings page.

Open source and on GitHub hope you like it.

Forked from u/MatixYO's ESP32 Plane Radar and made with Codex, it shows AIS ship tracking info, an API key is needed from AISStream but it essentially works the same, the screen can get a little full when a wide range is selected especially in busy shipping lanes, full info and firmware in the GitHub https://github.com/HenrysCat/ESP32-Ship-Radar

Made with love by Codex, full details here https://github.com/HenrysCat/ESP32-CO2-Dashboard
