The laser head kit presented in 2018 turned the Elektor Sand Clock of 2017 into a clock that writes the time on glow-in-the-dark film instead of in sand. A few years later, the Sand Clock was redesigned to use the Raspberry Pi Pico instead of the Arduino UNO — this version is currently available in the Elektor Store. Therefore, it is only logical to also reissue the laser head modification for the current Sand Clock. And why not use the clock to make drawings? In this article, we explain how you can achieve this.
