I’m Kevin, an electronic engineer. These are my current projects, with the notes along the way.

A private home for projects, daily plans, ideas, and garden records. Somewhere to decide what to do and remember what happened.

Earlier engineering
Work from Analytical Robotics and UCD, plus the personal build that taught me the most about timing and wiring.

Two generations of a mobile robot: localisation, perception, planning, electronics, and the mechanical build.

Beam steering, beam shaping, and optical switching, from Zemax models to the optical bench.

One hundred hand-soldered LEDs, multiplexed into a display that plays Pong with two physical controls.
Off the bench
A weekend LED cube, a Python game, and two growing records that are really about keeping notes.

A small hand-soldered cube made to learn multiplexing and animation.

A Space Invaders-style game with movement, projectiles, enemies, and scrolling scenery.

Dated photographs, planting notes, and weighed harvests from the 2026 kitchen garden.

Microgreens, herbs, and propagation under lights, with photographs as the notebook.
About
I’m an electronic engineer working on smart-building systems at Hereworks. At home, I like making things that connect software to the physical world.
I studied at UCD, worked on optical research with Huawei, and helped build autonomous robot prototypes at Analytical Robotics. This site is a place for the projects I kept coming back to, and the photographs and notes along the way.
