Fuzayel Mahmud.
I build things to solve problems.
I also build things simply because I want to know if they can be built.
Exploring electronics, automation, embedded systems and ideas that refuse to leave my brain alone.

Featured Projects
A few experiments and builds currently on the bench.
Experimental
WS2812 Analog Clock
A clock that intentionally does not move clockwise. It explores alternative ways of representing time using addressable LEDs and non-linear motion.
ESP32WS2812C++
In Progress
AI DeskBuddy
A companion AI focused on accountability and reminders rather than doing the work itself. It sits on the desk and gently keeps you honest about what you said you would finish.
ESP32PythonLocal LLM integration
Research
Dementia Reminder System
A family-assisted scheduling and reminder device that helps patients remember medicine and important daily activities while keeping family members in the loop.
ESP32Custom PCBAudio
In Progress
PCB Manufacturing Workflow
Improving PCB design and manufacturing processes through better organisation, checklists, and workflow design rather than just better tools.
