Baremetallics

Maxwell’s equations describe how electric and magnetic fields behave. If you work on embedded systems or PCB design, these equations explain many things you see in real hardware.

I’ve been working with Non-Volatile Storage (NVS) in Zephyr to handle logging and Bluetooth bonding information. NVS works like a simple key-value database: data is stored as an id-data pair, and Zephyr provides APIs (and even an example project) ...

For many embedded engineers, “the cloud” feels abstract and kind of mysterious. It was the same for me. IoT devices today are always connected: sending, receiving, analyzing, and showing data. But how does it actually work behind the scenes?

The V-Model is a product development lifecycle that maps design phases on one side and testing phases on the other. It’s simple, easy to follow, and works well for small and medium projects like smart appliances or wearables.

Error handling is tricky. On one side, the caller needs to react to errors. On the other side, the more error details you pass back, the more complex the caller code becomes. Complex code means harder to read, harder to maintain, and more bugs. An...
