WALKING GEIGER COUNTER WITH GPS MAPPING

Introducing the Walking Geiger Counter, a fully custom-built portable radiation detector with integrated GPS logging and real-time mapping. This project combines common maker hardware with a sleek, 3D printed design and a powerful custom-developed mobile app for comprehensive radiation data capture and visualization. HOW IT WORKS:1. Hardware & Core Components:CAJOE Radiation Detector Module: The central sensing element, detecting beta and gamma radiation using an SBM-20 Geiger-Müller tube.ESP32-C3 Mini Development Board: The project's brain. It's programmed with firmware that listens for each pulse signal from the CAJOE module. For every pulse, it sends a simple, immediate serial response via its USB-C port.Custom 3D Printed Case: A durable, ergonomic enclosure (available here) that houses all components, with a clear window for the Geiger tube and accessible ports.Smartphone: Connects via USB-C to receive the serial data and run the user interface.M3 threaded inserts (4.5 mm O
