Projects
Software, hardware, and creative technology.
Taptag
A Gem for interacting waveshare PN532 HATs on the Raspberry Pi. Includes glue code for the C Library, reading / writing capability for cards, and an encoder to make storing information within the card easier.
PiMaker
A CLI configurator for Raspberry Pi. Recipes describe what a Pi should be, from networks, boot options, packages, gems, repos etc. then PiMaker applies them, from flashing the card through to running setup over SSH. The tool I use for every Pi I build.
