SPRAYai - autonomous agricultural spray system

Why

Pesticide use is a fundamental aspect of modern farming. The UK alone applies ~17,000 tonnes of pesticide every year. Reduction of pesticide usage can provide numerous economic, social, and environmental improvements.

What

I developed a system capable of recognising weeds through custom neural network computer vision system. The positions of each weed are then fed to a mechanical 'spray box', which actuates a spray nozzle to target weeds individually.

I developed the mechanical and electrical system (including a custom multi-layer PCB), trained a YOLO neural network on a custom synthetic dataset, and designed and implemented a fully functional user interface built on web technologies.

A fully functional user interface was developed to allow the farmer to interact with the system.

rotaprint - Rapid Prototyping Printer for Cylindrical Components

Why

The client needed to apply graphics to cylindrical drums for user trials. The process is very labour intensive, but the scale is too small for commercial rotary printers.

What

Working in a team of six, I helped develop a concept for a rotary prototyping printer, capable of batch production and multi-colour graphics.

I developed software capable of projecting a 2D graphic onto a 3D sphere, which could then be loaded into the printer UI by a user. Persistent settings were managed with a relational database, and real-time print stats were relayed over WebSocket.

ultrasonics - Synchronise Music Playlists Between Streaming Services

Why

I like listening to music, but I tend to switch between different services, including Spotify, Plex, and my local offline library. This causes issues when I have dozens of playlists spread across each platform.

What

I wrote a server application capable of synchronising music playlists between a range of supported music services.

The ultrasonics homescreen, with multiple user-creatable 'applets' for syncing playlists.

The application is built on the concept of 'plugins' and 'applets'. Plugins can be dragged-and-dropped in to extend ultrasonics functionality (for example to add additional streaming service support).

Applets allow the user to build their own 'recipe' for syncing; e.g. they could take one playlist from Deezer, three playlists from Spotify, mix them using a recommendation algorithm, then save them all to Plex.
