PORTFOLIO

Personal projects

My own work — separate from the client projects on the Services page. These are what I build to grow as an engineer and maker: pushing my electronics, CAD/CAM, 3D scanning and mesh work, and controls. Click any project to read how it was built.

Reaction-Wheel Cube

A three-axis reaction-wheel cube — spacecraft-style attitude control on a desk. Spin a flywheel one way and the frame torques the other, which is enough to catch the cube on a single edge.

Toby — Tracked Robot

A 142-part printed tracked robot running a Raspberry Pi 5, RPLIDAR, and a camera, driven from a local web interface with live video and LiDAR room mapping.

Puller UAV

A one-metre fixed-wing UAV, designed from the wing section outwards and built as a complete airframe. It flew once, stalled on the climb-out, and the CFD I ran afterwards predicts its lift within 1.7 % of the airframe's measured weight.

Streamlines over the aircraft, coloured by velocity — upwash ahead of the wing, downwash behind it

Vorticity isosurface at 800 1/s — horseshoe vortices wrapping the wing and fin roots

Surface pressure, upper surface — the blue suction across both wings is the lift

EVERYTHING ELSE

Arctos Robot Arm

On 14 August a joint drove 111° the wrong way into its own end stop. The clamp that should have caught it was blind to exactly the two axes that ran away.
