Welcome to The Eremitic Engineer — a personal journey through the world of open source electronics, firmware development, and microcontroller projects.

👋 About Me

I’m a passionate engineer working on embedded systems using tools like:

ESP32 – a Wi-Fi/Bluetooth powerhouse
Raspberry Pi Pico – based on the RP2040 dual-core microcontroller
Sensors – BME280, VEML7700, GPS modules
Protocols – I2C, SPI, UART, BLE, LoRa

🔍 What You’ll Find Here

This blog covers topics like:

Real-time task scheduling with FreeRTOS
Sensor interfacing and I2C troubleshooting
Data logging to SD cards
Wireless communication with BLE & LoRa
Power-saving tips for battery-powered devices

Most projects are open source and documented with schematics, source code, and step-by-step explanations.

🧰 Tools I Use

C++ & CMake
Hugo (for this site!)
KiCad (for PCB design)
VS Code & PlatformIO
JLCPCB, PCBWay (for prototyping)

💡 Why Open Source?

I believe in the value of learning-by-sharing. Every schematic, line of code, or insight posted here is meant to help others avoid dead ends and focus on building cool stuff.

If my work has helped you, consider reaching out or sharing your own projects.
