Projects

I’m Kevin, an electronic engineer. This is where I keep notes on current smart-building and IoT work, along with robots, optical systems, electronics, software, and a kitchen garden.

Selected projects

Current IoT work and a few older projects I still like coming back to.

ESP32-C3 environmental sensor board beside a blue printed enclosure

Current IoT work2026

Smart-building platform

Sensors, cloud services, a room-by-room web view, and one controllable radiator joined into a working system for a real home.

Current build2026

Air-quality sensor node

A hand-built ESP32-C3 device for temperature, humidity, and CO₂, with a small printed enclosure made around the board.

Design studies2026

Air-sensor enclosure studies

An interactive exploded model of three printable housings for the sensor node, with drawing sheets and sections generated from the same numbers.

Analytical Robotics2020

Autonomous robot prototypes

Two versions of a mobile robot I worked on at Analytical Robotics, covering localisation, perception, planning, electronics, and the mechanical build.

UCD + Huawei2018–2019

Optical systems research

Research at UCD with Huawei on beam steering, beam shaping, and optical switching, using Python, MATLAB, Zemax, and an optical bench.

Personal build2020

10×10 LED matrix + Pong

A 10×10 LED matrix I soldered and programmed to play a simple game of Pong with two physical controls.

About

Current work · Hereworks

Smart buildings and IoT

I currently work at Hereworks around smart-building systems and IoT: the devices, controls, networks, and software that need to work together inside a building.

I’m an electronic engineer who likes projects that involve both code and physical things. I studied Electronic Engineering at UCD, then worked on optical research and autonomous robot prototypes.

This site is mostly a place to keep the photos, notes, and lessons from those projects together.
