Sandi Garimella
Builder. Mentor. Dad. I write about AI tooling, the things I build on the side, places I've been, and what I'm learning — from code, travel, kids, and audiobooks.
- Porting the $25 learning toy to an ESP32-P4 with a 7-inch MIPI DSI display: dual-chip architecture, LVGL 9, the PSRAM trick that fixed display jitter, OTA updates, and an SD-card question bank — with the AI-assisted workflow that made a solo port possible.
- A complete, replicable guide to the offline ESP32 learning toy I built for my 6-year-old — parts list, firmware decisions, the one gotcha that bites everyone, and how I used AI coding tools to build it in evenings.
