A quick visual tour of the lamp's finished form and build details.
📝 Overview
✨ Highlights
- 10 brightness levels for quick adjustment with a short press of the rear button
- Multiple lighting modes for dynamic color and motion effects with a longer press
- Open-source firmware with full source available on GitHub
- USB-C powered convenience for simple plug-and-play use
🛠️ Why it stands out
This project is designed to feel both functional and personal. The enclosure is 3D printable, the firmware is easy to customize, and the output is tuned for mood lighting rather than just utility.
It is a great fit for makers who want a small, visually appealing build that is easy to tinker with and simple to adapt for different effects or color palettes.
The result is a small lamp with a premium feel, a flexible control scheme, and a highly customizable lighting engine.
