From the project

"Where ideas become circuits before they become products."

"Where ideas become circuits before they become products."

This repository contains my collection of hardware and embedded engineering prototypes.

Instead of polished end products, this repository documents experiments, PCB designs, robotics projects, firmware, and proof-of-concepts developed while exploring electronics and embedded systems.

Custom PCB designed in KiCad for audio signal sensing using the LM358 operational amplifier.
