Working on a small animal-detection system using a USB camera + Raspberry Pi + GPS module. The system detects animals through the camera and records their location coordinates using GPS.
Working on a small embedded electronics project using an ESP8266, power module and custom wiring. Still improving the circuit and enclosure, but wanted to share the current prototype.
Found this beautiful cutaway of an inline 4-cylinder engine. Seeing the pistons, valves and crank mechanism exposed like this makes understanding the 4-stroke cycle much easier. The mechanical engineering inside these things is seriously impressive.

Made this GPS tracker using an ESP32 + GPS module, with a 4-digit display, buzzer, LED indicator and relay. It’s currently a prototype on perfboard. Looking for feedback on the design and ideas to improve it before making a proper PCB.
