01 — The brief
The challenge
To design and build a secure, responsive laser-tripwire intrusion detection system using microcontrollers, laser diodes, and photodetectors, providing instant audio/visual alerts when the perimeter is breached.
02 — The approach
My approach
Configured hardware interrupts on the MCU to handle microsecond photoresistor state changes. Engineered custom debouncing circuits to prevent false triggers, and constructed a compact, 3D-printable housing for aligned emitter/receiver modules.
03 — The result
Outcome
Successfully built and demonstrated a functional hardware prototype, documented in a comprehensive walkthrough video showcasing trigger calibration and alarm state resets.
Process
From discovery to delivery
Discover
Audited the existing hardware + embedded systems landscape, interviewed stakeholders, and mapped user pain points unique to Laser.
Define
Translated insights into clear product principles, information architecture, and a north-star moodboard aligned with the brand.
Design
Configured hardware interrupts on the MCU to handle microsecond photoresistor state changes. Engineered custom debouncing circuits to prevent false triggers, and constructed a compact, 3D-printable housing for aligned emitter/receiver modules.
Deliver
Shipped a production-ready system with documentation, design tokens, and handoff specs for engineering.
