  Over the years I’ve accumulated a fair amount of robot source code — old projects in zip files, folders with broken .git histories, repos that were once on a long-gone GitLab instance.

  Following on from my post on i2s playback with Raspberry Pi Pico, this is a write up of the recording lab notes I made in 2023. This was actually the trickier bit - getting an i2s MEMS microphone to capture audio and write it to a WAV file on an SD card. I completed this in 2023, but only got round to writing it up in 2026 - better late than never!more...
