A selection of engineering work we can discuss publicly. Hardware development is often covered by non-disclosure agreements, so these examples encompass client engagements, internal hardware developments, and academic projects, with context noted for each.
Client project
Automated post-operation machining centre
An automated machining centre with a component buffer and automatic part detection, developed to run continuous post-operation cycles without manual intervention between parts.
View case study
University teaching project
A working model for engineering teaching
A motor-driven strain-wave gearbox featuring an exposed flex-spline and live reduction dial, engineered as a physical demonstrator for engineering education.

Personal project
Stepper motor speed-torque characterisation
A rig built to characterise stepper motor speed-torque behaviour across supply voltage, current, and microstepping configuration.

Personal project
3D-printed and machined reduction drives
Prototypes of a compact cycloidal reduction drive, built while developing a robotic arm, exploring 3D-printed and machined versions of the mechanism.
View case study
Client project
Reverse-engineered from reference and measurement
CAD models of 1970s motorcycle components rebuilt from reference and measurement, with a handful machined to verify the models against the originals.
