Absurdly Accurate Clock
A GPS/PPS-disciplined clock on a Raspberry Pi Pico 2. Firmware keeps authoritative UTC independent of the display, drives a serial VFD over RS-232, and serves a read-only network-time interface.
Work
Serious things, ridiculous things, and the ones that are both.
Engineering case studies from DIM8 Labs, followed by a set of self-initiated concept web builds.
