The EasyGimbal is an autonomous “robot cameraperson” designed to follow a subject using AI-based computer vision. A camera module is mounted on a 3D-printed gimbal with two motors: a 28BYJ-48 stepper for horizontal (yaw) rotation and an SG90 9G servo for vertical (pitch) rotation. An STMicroelectronics STM32N6 microcontroller runs an edge AI model for gesture recognition, interpreting body movements to control the motors in real time. 

Subject Tracking with AI

The modern field of electronics — and by extension, hobbyist electronics — exists in a fundamentally different space than it did just a few decades ago. Where my grandfather had to import physical books to learn the basics, save up for months to buy an 8-bit CPU, and order datasheets by mail, I have the sum of human engineering knowledge available in my pocket, 24/7. Today, I can buy a microcontroller for 3 cents that can fully emulate the CPU he treated as a luxury purchase. But this accessibility comes at the cost of c...
