Key Project Highlights

Built for efficiency, elegance, and deep Home Assistant integration.

Guition JC2432W328 CYD

ESP32 dual-core processor with a crisp 2.8" 240x320 capacitive touch LCD. Powered via USB-C on your desk.

RGB Moodlight Status LED

Utilize the built-in RGB hardware LED as an ambient status halo on your desk. Instantly see print completions or usage warnings.

openHASP Studio — Built by Me

I created openHASP Studio, a visual drag-and-drop editor for openHASP layouts, and used it to design these pages instead of hand-writing JSON coordinates. Still a work in progress, but fully functional.

Firmware Contributor

I contributed to the openHASP firmware build files that bring official support for the Guition JC2432W328 hardware, including this display's pinout and moodlight configuration.

Home Assistant & MQTT

Native MQTT integration with openHASP custom component. Effortless two-way state binding with zero lag.

Claude AI Usage Tracker

Track daily API calls, token burn, and total cost directly on your desk to stay informed on AI resource consumption.

BambuLab 3D Printer Sync

Live progress percentage, nozzle/bed temperatures, subtask name, and ETA updates straight from your BambuLab 3D printer.

openHASP Studio — a tool I'm building

Tired of writing openHASP UIs as raw JSON, I built openHASP Studio myself — a visual drag-and-drop editor for openHASP touch plates. It's still a work in progress, but already functional enough that I used it to design every screen on this display.
