About
Albert David
Prolinix is my personal lab and blog where I document hands-on embedded projects, from custom PCBs and firmware to Linux-based systems for automotive and IoT applications.
By day I work as a System Architect at Harman, designing automotive display architectures, real-time video pipelines, and embedded platform software. Outside of work, I build open-source tools and hardware — CAN-based sensor nodes, pocket router hacks, DIY infotainment systems, and whatever else lands on the workbench.
What you’ll find here #
- Embedded Linux projects (Buildroot, OpenWrt, kernel/driver work)
- Custom PCB designs with KiCad
- IoT and home automation builds
- Firmware for ESP32, ATtiny85, and other microcontrollers
- Practical tutorials with schematics, BOMs, and source code
