AI Bunny is a cute, educational, interactive companion in a 3D-printed bunny enclosure. It listens, speaks, responds, teaches—practicing language, storytelling, educational games, answering questions. This DIY device brings edge AI to life for kids and grownups.

Learn how to interface the ESP32 thermal printer with a complete tutorial. Includes PNP-500 wiring, Arduino code, circuit diagrams, and projects for receipt printing, barcodes, and QR codes. Perfect for microcontroller projects and IoT applications.

This tutorial is ideal for students, hobbyists, or educators who want to integrate precise distance sensing into projects such as robotics, automation, obstacle detection, or smart measuring tools.

This project is to connect an external USB camera on UNIHIKER and use the camera to recognize the object, find the square object in the frame and frame it out.

This project is to connect an external USB camera on UNIHIKER and use the camera to recognize the hands and draw keypoints on it.

The UNIHIKER-based Yolo license plate recognizer uses a USB camera and YOLO model for fast, accurate recognition, enabling smart vehicle monitoring, efficiency, and security.

This project aims to make a wireless handwritten dot matrix screen with UNIHIKER.

The successful integration of TFT_eSPI and Adafruit sensor libraries proves this AI-focused board has untapped potential for traditional microcontroller applications.

This article introduces one via UNIHIKER, micro:bit expansion board & camera, merging hard/soft for precise tracking.

My wife’s setting up a garden. As a tech fan, I used DFRobot’s Beetle ESP32-C3 (compact, core/expansion boards, many interfaces, lithium support) to make an env monitor (temp, humidity, light, soil moisture) – data on screen & to server via MQTT for future auto irrigation.

We may modify video backgrounds (e.g., distractions/unsuitable colors) via real-time replacement.

This project interfaces a USB camera with UNIHIKER to detect objects, box them out and recognize them.
