01 / 03INTRODUCTION
A FEW THINGS IN THE WORKSHOP

Selected work.

Small steps, practical outcomes.
More projects will find their place here.

01 / PROJECT IN PROGRESS
ESP32 & IOT

Antenna Rotator Web Control

A browser control panel for a YAESU G-450CDC rotator, served straight from an ESP32 over Wi-Fi.

ESP32 & IOT

Antenna Switcher

A Wi-Fi antenna selector that switches between antennas from any phone on the same network.

C3 Ad-Blocker

A tiny DNS ad-blocker that runs on a $2 ESP32-C3 board and blocks ads across your whole network.

OTHER PROJECTS

More experiments coming

A home for practical tools, electronics experiments, and ideas worth building.

The RotorControl web interface — a compass showing the antenna position beside manual rotation, lock, and favourites controls — shown next to its settings screen.
01 / PROJECT
ESP32 & IOT

A touch-friendly web interface that runs on the device itself — no app to install and no cloud in between.

  • A compass view with live position, target angle, and cardinal directions.
  • Manual rotation, a callsign lock so one operator can hold the rotor, and saved favourite bearings.
  • A settings screen for colour themes, compass elements, font size, and language.
  • Served by the ESP32, so any phone or laptop on the network can control the rotator.
ESP32EmbeddedWeb UI

Built on the open-source RotorControl interface by Stefan Wraase, adapted for this rotator.
The DezCom antenna control page with colour-coded antenna buttons, next to the antenna settings page.
02 / PROJECT
ESP32 & IOT

Pick the antenna you want from any device on the network, with the active one clearly shown.

  • One-tap antenna selection with a clear active and inactive state.
  • A settings page to name each antenna and set how many relays are in use.
  • Runs on the ESP32 as a single small web app, with no outside service involved.
ESP32RelaysWeb UI
The C3 AdBlock dashboard: live blocked and allowed totals, a per-client table, custom blocked domains, and blocklist and firmware update controls.
03 / PROJECT
ESP32 & IOT

A Pi-hole-style DNS sinkhole for the whole network, running on a low-cost ESP32-C3 with no extra memory chip.

  • Keeps 140,000+ blocked domains as compact hashes in flash, using only about 50 KB of RAM.
  • Answers blocked lookups with 0.0.0.0 and forwards everything else to your normal DNS resolver.
  • A built-in web dashboard shows live stats and per-client counts, and lets you block or ban with one tap.
  • Firmware and blocklist update over Wi-Fi, and the board fits a printable case for the router USB port.

Based on the open-source esp32-c3-adblock project by M-Abozaid, adapted and hardened for this build.

A LITTLE ABOUT ME

Curiosity is
the starting point.

I like figuring out how things work — then finding a way to make them work better.

My workshop sits somewhere between software, electronics, and everyday problem-solving. I experiment with web apps, ESP32 projects, and connected devices, learning by building and improving one idea at a time.

01Build with purpose
02Keep it practical
03Always keep learning
HAVE AN IDEA? LET'S CONNECT.

Good things start
with a question.

Follow the projects, see what I'm learning, or explore the code behind the work.
