TPGmini v2: A Tiny AR Wearable Companion Powered by XIAO ESP32S3 Sense
In a world where wearables often prioritize form over function, TPGmini v2 is redefining what it means to create truly personal tech. Developed by Nguyễn Minh HIỂN, this ultra-compact, DIY AR glasses kit merges minimalist design with customizable intelligence. Whether clipped onto your favorite glasses or used as a standalone AI assistant, TPGmini v2 invites makers to bring their creative visions to life.
With its powerful XIAO ESP32S3 Sense core, a vibrant OLED display, and a tactile keyboard switch for interaction, TPGmini v2 is more than just a gadget—it’s a creative platform. Out of the box, it includes essential apps like a Gemini AI assistant, Live Transcription, and a Camera with retro flair. But it doesn’t stop there: it’s built for personalization, ready for developers to shape its future through miniOS.
Hardwares
Despite its minimal footprint, TPGmini v2 is packed with carefully selected components that balance performance and elegance:
- XIAO ESP32S3 Sense
- SSD1306 OLED Display (64×32)
- Custom Keyboard Switch
- 3D Printed Enclosure
- Tiny Reflective Mirror
How It Works
TPGmini v2 simplifies interaction through one physical button — yet it opens a world of capability. Here’s how:
- Click to switch between miniOS apps like Gemini (AI assistant), Live Transcription, and Camera.
- Hold to confirm actions — such as recording a video or querying your assistant.
- Customize the button’s behavior to suit your personal workflow.
When attached to glasses, it offers a hands-free HUD-like experience. Standalone, it becomes a mini companion for real-time information, AI responses, and spontaneous media capture.
Apps like Live Transcription leverage the XIAO ESP32-S3’s compute power to transcribe spoken words directly on the OLED, while Gemini brings voice-activated AI to your field of view. The Camera app adds nostalgia and functionality with single-click photos or short video clips.
With miniOS as the backbone, developers can also write and deploy their own apps — transforming TPGmini v2 into a versatile micro-wearable for experimentation, utility, and creativity.
Bring TPGmini v2 to Life
TPGmini v2 isn’t just another wearable — it’s a call to rethink how we interact with tech. Whether you’re a maker, hacker, or everyday user, this project is yours to explore, remix, and build upon.
