About · Electronic engineer
I’m an electronic engineer working on smart-building systems at Hereworks. I studied at UCD, where I was lead programmer on a beam-steering research project with Huawei, then helped build autonomous robot prototypes at Analytical Robotics. At home I like making things that connect software to the physical world.
The live 3D view needs WebGL. The enclosure studies page shows the same model as drawing sheets.

City data · Ongoing
Dublin’s public data on one map.
Bikes, scooters, river and tide gauges, weather and air quality across the city. Every reading keeps the time it was taken and where it came from.
Bikes free at each station, and when it last reported.
Homemade CO₂, temperature and humidity sensors report through AWS IoT Core to a room-by-room dashboard. A Bluetooth bridge sets an electric radiator and waits for it to confirm.
Follow a reading through the system
An action RPG that runs in the browser, called Ashen Vault until September. Warrior, Mage or Archer down three floors, against enemies that get thrown, pinned and bowled over.

My own planner: a short list for today with a focus timer, each project’s history, and the garden record.
Try a day in Life OSSelected notes, dated when added.
Three floors, a Warrior, a Mage and an Archer with 24 abilities between them, and new pictures of each.
Playable at play.kevinoflannagain.xyz: three weapon classes, eighteen chambers, and over four hundred tests behind them.
The live map, the layers panel, the Water Clock, and the stories page as they look today.
Five stages, from jumper leads to a printed enclosure with a round display.
Bikes, water levels and weather on one map, each reading with its time and source.
A daily list, a focus timer and the garden record, in a walkthrough you can try.
Slab, Gauge, and Halo: a flat lid, an angled face, or a round body.
A summer snapshot of planting notes and the harvests brought indoors.
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 multi-robot prototype: UWB localisation, a Jetson Nano and Teensy 4.1 on board, and a second aluminium frame with four 250 W motors.
Lead programmer on beam-steering algorithms in 2018, then beam shaping and optoelectronic switching in Zemax in 2019.
One hundred hand-soldered LEDs, multiplexed into a display that plays Pong with two physical controls.
Off the bench
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.
