Projects
Web design and development for a community mapping platform co-created with Cambridge, Cardiff, and Wrexham Universities. Funded by the AHRC, it helps communities co-create open data maps to reveal local need and shape better futures.
A no-sew, reusable face mask designed during COVID-19 using NASA’s ISRU principle — constructable from household materials. An adjustable headstrap eliminates ear pressure, a custom-formed nose piece creates a seal, and a replaceable filter clamp means only the filter needs washing. 3D-printable nose piece files on Thingiverse; a wire version works with a coat hanger and pliers.
A tweetable aluminium baseball bat on a servo arm, triggered at live events. Featured on Hackaday.
An Arduino-based buzzer and scoring system for a fast-paced weekly pitching contest. Featured on Hackaday.
A phone-controlled photobooth built on Raspberry Pi. Featured on PetaPixel.
A desktop companion to help remote workers fight distraction and build focus. Featured on Develop3D.

Bio
I design and build things at the intersection of software, craft, and ideas. Interested in tools, systems, and anything that blurs the line between digital, physical, and the more than human world.
