Ian Renton

Software engineer and builder of robots
Bournemouth, UK

Hi! I'm Ian Renton. By day, I am a software and systems engineer in the naval defence industry, specialising in command & control of autonomous vehicles and communications networks. By night I build robots and web applications, and play with radios, alongside being a husband, father, cook and gardener.

A military tactical software display showing symbols representing boats and planes


"Plane/Sailing" is my home aircraft and ship tracker. It receives ADS-B, AIS & APRS signals via antennas on my house, processes them to share with popular tracking websites, and displays the combined results on a website using military symbology.

The Raspberry Tank, a model Tiger tank shown with a camera and sensors fitted

Raspberry Tank

The Raspberry Tank was possibly the first tank-like robot powered by a Raspberry Pi, way back in 2012. It’s smartphone- or laptop-controlled, streams video from its webcam, fires plastic pellets and can navigate autonomously.

A quadcopter fitted with a Raspberry Pi, sat on grass


Because the Raspberry Tank was confined to just the two boring dimensions, I built a quadcopter and put a Raspberry Pi on that too. It features live video streaming and is switchable between remote and autonomous control.

Weird Stuff from the Archives: ArmJoe

Over the years I have tried to preserve some of the weirdest software, videos etc I came into contact with, just in case someone years from now asks “hey, do you remember that…” and not only do I remember, I still have a copy. Today on “Weird Stuff from the Archives”: did you know there was a Les Miserables beat-em-up? (It’s what Victor Hugo would have wanted.) This is probably version 1.4 of the game, which dates to around 2006....

Ghost in the Machine: "Haunted WiFi" with Home Assistant

Since starting to play with Home Assistant, it’s consistently impressed me with just how many possible integrations it has. From the things you’d expect, like Google Home, Siri, and smart lights, to the unexpected, like cars and smoke detectors, to the downright strange—it warms my weird little heart that I now have the ability to turn on my bedroom lights using a VHF radio. And of course, it’s open source with open APIs, so you can code up any new...

A New Home Server Setup

In a move that feels almost heretical, given my history with the devices, I am moving away from using Raspberry Pi computers for my various “home server” projects. This has been driven in particular by a desire to tidy up the area of desk used for Plane/Sailing by powering all three RTL-SDR dongles straight from a PC, without the added hassle of a powered USB hub. Inspired by videos and posts I’ve seen online, I have switched out my Pis...
