E-Ink Dashboard Display
On a Raspberry-Pi!

After setting up Pi-hole on my home network, I decided to take it a step further by building a small dashboard on an e-ink display connected to a Raspberry Pi. What started as a simple script pulling data from the Pi-hole API quickly grew into a modular mini-framework.The framework uses a simple “page” system — each page is a lightweight script with its own init and update functions, along with configurable refresh intervals. This makes it easy to duplicate and tweak pages without touching the core display logic. A top-level controller manages cycling between pages and handles physical button inputs to allow manual switching.So far, it displays:
• Pi-hole statistics
• The current position of the ISS
• The next upcoming Formula 1 sessionThere’s something satisfying about having a little passive display that just quietly works — and this has been a fun way to blend scripting, APIs, and hardware in a project I can tinker with over time.

Godot Platformer

After Unity's licensing controversy I thought it was probably time to get some projects going in other game engines. I've used Unreal a bit before and while it's great, it's quite heavy weight for the smaller projects I like to play around with. I'm more of a tinkerer when it comes to personal projects I guess?Anyway, I hadn't even heard of Godot at the time but have quickly become very familiar with it and I'm excited to see where it goes!So I'm building a small 3D platformer, or at least a level or two. Just to get my bearings in the engine. Really enjoying it so far.

Simpsons Frame Quiz
React

Guess the Simpsons episode from a single frame! This probably already existed but it was a fun little project to refresh some web skills. (Although I used Tailwind UI, and I really didn't get on with that compared to MUI. But some more time would probably help!)This uses the Frinkiac API to have access to 10 seasons of Simpsons frames.You can play it here: Simpsons Quiz

I didn't have a picture of it...

Red Dead Redemption 2 - Twitch Chaos Mod
Modding

Before you get too excited — no, this isn’t the official one
I put this together before an actual Red Dead Redemption 2 chaos mod existed, inspired by the popularity of the GTA V version at the time.The idea was to let Twitch chat trigger chaotic events in-game using commands. I built a simple C# command-line app to handle Twitch interactions, tracking votes from the chat. On the game side, I used standard RDR2 modding tools to poll the app every 30 seconds and run the most voted-for command.I’d never tried anything like this before, so it was a fun challenge — definitely a few headaches along the way, but really satisfying to get working. I streamed it a handful of times :)

AI Shopping Network
Twitch

A live stream on twitch using ChatGPT to generate fake products and sell them as if its a teleshopping channel. Unity is used to produce the real time visuals of the scripts generated by ChatGPTThis was a very quickly produced project to catch the AI stream hype. So it's a bit of a messy project, but I had it set up so the whole process was automated. (I just had to read what was generated because the more you turn up the randomness the more risky it would get)

Paradrome
Unity & VR

Paradrome was originally created by one of the academics as part of CGD (Computing & Games Dev), over the years there have been a number of versions. A couple of which I have been able to work on. Originally just maintaining the older Unity 5.5 version so it could be used for open days, we also took on the challenge of porting the gameplay to a VR headset.The goal is to paraglide your way down an erupting volcano to safety. You sit in a paragliding harness suspended above the ground and pull two ropes either side of you to steer.

Student Showcase App
iOS, Android, React

Originally built using Xamarin as a cross-platform mobile app for iOS and Android, this project was created during the first lockdown as a way to improve how student work was presented at university showcase events.The app used a self-hosted database and an ExpressJS API backend. To avoid handling user-generated uploads directly — and to keep data handling straightforward — submissions were collected via internal Microsoft Forms and content was manually uploaded by an admin. This helped maintain control over data quality and security, while making sure all displayed content was student-approved.Although the app was never launched live (due to privacy concerns and lack of time to support it), the Xamarin version was fully functional. Later, I rebuilt parts of the project using React to sharpen my web development skills — though this version didn’t reach feature parity, the process itself was a valuable learning experience.

Login Tracking and Remote Desktop
React

Built quickly during the COVID-19 lockdown to give students secure remote access to on-site Windows lab machines. The goal was to make remote desktop usage feel as seamless and student-friendly as possible, even for those unfamiliar with RDP tooling.The system presented a clean web interface showing available machines in real time. Students could simply click a machine to generate a unique RDP file, preconfigured with connection info. The portal managed machine availability by not displaying machines in use and showing them when the session ended, preventing overlap or conflicts. Usage was tracked through a custom ExpressJS backend & Database, this allowed someone to login physically while the website responded accordingly.PC's were organised into their labs so students could access familiar software. Each lab also queried the timetable API to highlight when certain students had priority.

Retro Portfolio Site
React

My "old" portfolio site, wanted to do something a little different so the whole thing was designed to look like Windows 95/98.The site used Contentful as a CMS and had an ExpressJS backend to act as an API for the front end that was build in React.
