Radar scanner, front view

01

Autonomous Radar Scanner

A 180° ultrasonic radar built around an Arduino UNO: an HC-SR04 rangefinder on a servo sweeps the field of view while a Processing app renders detections in real time. All sweep and detection logic written from scratch in C++.

Outcome

Real-time object mapping across the full 180° sweep with a live radar display.

Flood-resistant house from the front, hull wrapped and tethered on the workbench

Flood-Resistant Station-Keeping House

A model house that holds position in rising floodwater. I led a seven-person team and owned the electronics and firmware: an Arduino UNO R3 reading an MPU-6050, driving DC motors through an L298N H-bridge on an XPS foam hull.

Outcome

Held position under simulated flood conditions, delivered under the $170 AUD budget.

CO2 dragster

03

CO2 Dragster

A 45 g CO2-powered dragster modelled in Fusion 360 and machined from balsa, shaped to minimise frontal area and drag within competition rules.

Outcome

0.49 s over the 1 m track, top 5 in the year group.

Model rocket on the pad

04

Model Rocket

Designed and simulated in OpenRocket to verify the stability margin before construction, then built, balanced, and launched on a B6-4 motor.

Outcome

97 m apogee, stable flight, clean parachute recovery.

Truss tower, side view

05

Balsa Truss Tower

A balsa truss tower built for a structural efficiency competition. Geometry chosen to maximise load-to-weight ratio with predictable load paths; joints pinned and glued with weight tracked through the build.

Outcome

Failed exactly at the designed weak point under class load testing.

Warehouse rover, front view

06

Autonomous Warehouse Rover

A LEGO Mindstorms EV3 rover programmed to clear a warehouse-style obstacle course with no human input: ultrasonic sensor for obstacle detection, colour sensor for line following.

Outcome

Completed the full course autonomously.
