Assembling the Elektor Sand Clock Kit

Check out the build instructions for the Raspberry Pi Pico-based Sand Clock Kit. Once assembled, writes the current time in a layer of sand! Whether you're new to electronics or a seasoned designer, building this clock kit promises a rewarding, fun, and educational experience.

How about building your own unique timepiece? Check out this video and discover the Elektor Sand Clock kit. This step-by-step tutorial offers an engaging and easy-to-follow guide to assemble your Raspberry Pi Pico-based sand clock.

Starting with the basics, you'll learn about the required tools, and begin by testing the electronics. This involves plugging the Raspberry Pi Pico onto the baseboard, plugging the servo connectors, downloading software and establishing communication with the module from the Arduino IDE. All of this is pretty straightforward and the tutorial is very detailed.

Building the Sand Clock

Progressing further, you'll build all the mechanical parts. The clock is made of laser-cut acrylic sheets that are assembled together with screws and nuts. The tutorial guides you through the whole process, with attention to detail, so you can avoid mistakes during assembly, in particular with some asymmetrical parts that must be oriented correctly. Then, the PCB and the servos can be mounted inside the acrylic chassis. All in all, a smooth assembly process!

The video then guides you through interfacing the clock with a computer, using the built-in serial commands to calibrate the clock and set up the time. Fortunately, this is a one-time process, as the settings are stored in an EEPROM and the time is kept by a battery backed-up RTC. All that's left to do is admire the result!

Whether you're new to electronics or a more seasoned hobbyist, building this clock kit promises a rewarding and educational experience. Enjoy the video below:
