He sometimes blogs and has various things on GitHub, including:
Mega Drive MIDI Interface
A Mega Drive ROM written in C that exposes the console's YM2612 FM Synthesis & PSG chip as a MIDI interface over the Mega Everdrive X7 cartridge's USB connector. Provides a partial implementation of the General MIDI specification, as well as providing compatibility with GenMDM CC parameters.
Fastly VCL Experiments
Various proof-of-concept VCL snippets; including OAuth 1.0 signature validation on the edge. I have also co-authored an open-source tool for deploying VCL into Fastly.
ZX Spec: A TDD Framework for the ZX Spectrum
Aids development of Z80 assembly code on the ZX Spectrum by providing a framework for practicing Test-Driven Development. Written purely to prove that it was possible to do. It also scratched an 8-bit itch of mine and was pretty fun!
