From the project
A collection of 10 production-ready schematic & PCB layout designs From fundamental analog circuits to motor control systems — all designed in KiCad
I build for the messy, low-bandwidth, real world — where people need technology that actually functions. My engineering philosophy is simple: offline first, privacy always, real hardware required. I don't trust solutions that work only in ideal conditions.
From custom AI assistants to fiber fault detection engines, from IoT aquaculture platforms to portfolio sites with mini-labs inside — the list doesn't stop because the curiosity doesn't stop.
