Encrypted Off-Grid Communications (LoRa)
Engineered a custom firmware solution using C/C++ on ESP32 microcontrollers. Integrated LoRa radio modules for long-range wireless communication without cellular reliance and developed a custom encryption hash function.
Why I built this
I was interested in off-grid, long-range communication that doesn't depend on cellular or Wi-Fi. LoRa's low-power, long-range characteristics made it ideal for building a secure messaging system that works in the field.

How I built it
Wrote custom firmware in C/C++ for ESP32, integrated LoRa radio modules, and implemented a custom encryption scheme. Focused on range, power efficiency, and ensuring only intended receivers could read the payloads.
