Laser Head for (2024 Raspberry-Pi-Pico-based) Sand Clock
Replaces the stylus and the sand of the Sand Clock by a laser and a sheet of glow-in-the-dark sticker material.
Elektor project 240647
Replace the stylus and the sand of the Raspberry-Pi-Pico-based Sand Clock (from 2024) by a small laser module and a sheet of phosphorescent self-adhesive paper (glow-in-the-dark sticker material). The result is a bright display with good contrast, perfectly readable from afar, not lacking in charm. And, because the time now disappears by itself, it is way less noisy than the Sand Clock. Can also be used to make ephemeral art.
This is for the Sand Clock built around the Raspberry Pi Pico.
