Vulpes
An ESP32-based radio orienteering controller. This repo is for the code. There will be another repo for the schematic and PCB design.
What
Radio orienteering, or amateur radio direction finding (ARDF) is a sport where people run around and look for hidden transmitters. One necessary component is a controller on each transmitter that tells it when and what to transmit.
This is my attempt at a simple, easy-to-use controller with a low parts count. Rather than programming a microcontroller and/or using DIP switches, time delays, and sync cables, the ESP32 development board lets you set up each controller using a web browser.
[need links here for ARDF resources]
Hardware
I designed a simple custom printed circuit board (PCB) to make assumbling this controller easy to do. The repo for schematic and board design is here: [link to new repo].
Because the ESP32 doesn't track time when it is powered off, and I wanted to avoid specific delays (e.g., push a button two hours before an event starts), an additional real-time clock (RTC) is included. The RTC runs on a watch battery to track time when the controller is not powered on.
