Smart Curtain
Three motorised curtain rails on one ESP32, with limit switches, window sensors and a manual override that always wins.

Projects
Twenty builds, from a one-relay switch to a controller that runs a hydroponic system on its own. Each is written up for the reasoning — the constraint that set the design, what I picked, and the failure mode I was designing against.
Built and running
Installed, in daily use, and no longer something I think about.

Dimmable Light Beam
A PWM-dimmed LED beam on a custom PCB, switched by motion — the first board of mine that went straight from sketch to etch.

Scene Select
One controller, five lighting modes — the layer that made every other light in the flat worth automating.

Kitchen Relay & Sensor Node
Mains switching plus climate sensing on one small board behind the kitchen wall plate.

Seaside Outdoor Sensor Module
A battery-powered outdoor node for soil moisture and climate, built to survive salt air.

8-Way Smart Plug Bank
Eight individually switched and metered outlets in one 150 × 138 × 56 mm enclosure.

ESP-01 Relay Module
The smallest useful node — one ESP-01, one relay, one button.

Raspberry Pi Rack
A 3D printed stacking rack sized around airflow and cable clearance rather than board outlines.
In progress
Being designed or assembled right now.

Smart Coffee
A filter coffee machine rebuilt around an ESP32, with closed-loop brew temperature and voice control.

Bed Occupancy Sensor
Load cells under the bed legs so the house knows when I actually go to sleep, instead of guessing from a timer.

Macro Keypad
A desk keypad with tap, hold and sticky layers — one physical key doing three jobs without ambiguity.

Big LED Clock & Sports Timer
A large seven-segment display driven by shift registers, doubling as a count-up match timer.
Research & academic
Written work, with the full documents attached.

Hydroponic System Automation
Senior design thesis — a controller that holds a soil-free growing medium at the right pH, nutrient strength and water level without daily supervision.
Designed, parked
Worked out on paper but not built — usually because something needed measuring first, or a dependency moved.

Keypad Door Lock
A 4×4 keypad entry system with armed/granted/denied states signalled by light and buzzer.

Blackout Announcement System
PoE-backed emergency announcements and lighting that survive the outage they exist to announce.

PoE for Everything
Splitter boxes and 3D printed housings to bring Power-over-Ethernet to devices that were never designed for it.

Bedside Control Panel
A physical panel at the bed for the handful of things worth having a real button for.

Clock Shelf
A shelf that is also the enclosure for the clock — structure and housing as one part.

DIY Brushless Motor
Winding a BLDC motor from scratch to understand what the datasheet numbers actually mean.
Superseded
Replaced by a later revision. Kept because the reasoning still holds up.

ESP Connection Board
A breakout board, and the GPIO survey behind it — which ESP32 pins are actually safe to use.
