2026 · Team member - RF integration; oversaw avionics integration

Huia EDF UAV

A fixed-wing electric ducted fan UAV built by two six-person teams. I oversaw the avionics integration around ArduPilot and ran the RF and antenna placement study in Ansys HFSS, alongside battery thermal-runaway containment, ESC thermal characterisation and the launcher's electrical control system.

The avionics test bed laid out on a bench: a long plywood board carrying a ducted fan and motor at one end, with the ESC, battery, flight controller, RF modem and GPS puck arranged back along it.

Huia Avionics Feasibility

The avionics architecture for UC Aerospace's Huia, a multi-year project developing a high-performance fixed-wing UAV platform. It was built around a Cube Orange+ running ArduPilot, RTK-capable GNSS with a ground-based correction system, and long-range RF telemetry ground tested to approximately 20 km. The stack was integrated and validated on an electric proof-of-concept aircraft, with a commercial off-the-shelf airframe used as a separate autopilot test platform.

LoRa Launch Control System

A battery-powered launch controller talking to pad hardware over LoRa. It runs on dual 18650 lithium-ion cells with integrated USB-C charging, and its panel carries two seven-segment displays, status indicators and a launch button. The button interface is debounced in hardware using RC filters and Schmitt triggers rather than in firmware. I did the schematic design, circuit modelling and hardware validation of the controller board, and modelled the enclosure and mounting hardware in 3D CAD.

LoRa Range Warning System

A tripod-mounted field unit carrying siren and beacon alerts across a high-power rocketry range. I led the electrical design and implementation, covering PCB layout, RF front-end development and firmware integration around a NUCLEO-WL55JC and its STM32WL, with the LoRa stack configured half-duplex for bidirectional exchange between the launch site and range safety stations. The custom PCB runs from inputs up to 8S LiPo, generates regulated 12 V and 5 V rails, and switches the unit's siren and beacon.
