This bundle contains the popular Elektor Sand Clock for Raspberry Pi Pico and the new Elektor Laser Head Upgrade, offering even more options for displaying the time. Not only can you "engrave" the current time in sand, you can now alternatively write it on a glow-in-the-dark foil or create green drawings.
Contents of the bundle
Elektor Sand Clock for Raspberry Pi Pico (normal price: €50)
NEW: Elektor Laser Head Upgrade for Sand Clock (normal price: €35)
Elektor Sand Clock for Raspberry Pi (Raspberry Pi-based Eye Catcher)
A standard sand clock just shows how time passes. In contrast, this Raspberry Pi Pico-controlled sand clock shows the exact time by "engraving" the four digits for hour and minute into the layer of sand. After an adjustable time the sand is flattened out by two vibration motors and everything begins all over again.
At the heart of the sand clock are two servo motors driving a writing pen through a pantograph mechanism. A third servo motor lifts the pen up and down. The sand container is equipped with two vibration motors to flatten the sand. The electronic part of the sand clock consists of a Raspberry Pi Pico and an RTC/driver board with a real-time clock, plus driver circuits for the servo motors.
A detailed construction manual is available for downloading.

Elektor Laser Head Upgrade for Sand Clock
The new Elektor Laser Head transforms the Sand Clock into a clock that writes the time on glow-in-the-dark film instead of sand. In addition to displaying the time, it can also be used to create ephemeral drawings. The 5 mW laser pointer, with a wavelength of 405 nm, produces bright green drawings on the glow-in-the-dark film. For best results, use the kit in a dimly lit room. Warning: Never look directly into the laser beam!
The kit includes all the necessary components, but soldering three wires is required.
Note: This kit is also compatible with the original Arduino-based Sand Clock from 2017. For more details, see Elektor Magazine 1-2/2017 and Elektor Magazine 1-2/2018.

Dive into the world of Raspberry Pi with this huge book of tutorials, project showcases, guides, product reviews, and much more from the writers of The MagPi, the official Raspberry Pi magazine.
Raspberry Pi Pico 2 joins Raspberry Pi 5 in this, The Official Raspberry Pi Handbook 2025. Pico 2 comes with a faster processor than the original Pico, and uses less power – while still maintaining the same form factor and pinout. With both Pico 2 and Raspberry Pi 5 you can power any project you can imagine.
With 200 pages packed full of maker goodness, you’ll also find inspiration for your Raspberry Pi Zero 2 W, Raspberry Pi 4, or any other Raspberry Pi model you have – there’s something for everyone.
In this handbook you’ll find:
A get started guide that covers every Raspberry Pi
Everything you need to know about the brand-new Raspberry Pi Pico 2
Inspiring projects to spark your next build idea
Tutorials for makers of all skill levels
Guides for media centres, game emulators, and more!
Raspberry Pi Pico 2 Microcontroller not included
This bumper book is your definitive guide to everything Raspberry Pi. It’s essential for any maker with big dreams and a thirst for knowledge.
Fully updated for Raspberry Pi Pico W, this book gets you started with Raspberry Pi Pico – whether you’re using Raspberry Pi Pico for a home project, industrial automation, or learning (or teaching!) electronics and programming.
Microcontrollers, like the RP2040 chip at the heart of Raspberry Pi Pico, are computers stripped back to their bare essentials. You don’t use monitors or keyboards with them – instead, you program them over USB to take their input from (and send their output to) on-board input/output pins.
Using these programmable connections, you can light LEDs, make noises, send text to screens, and much more. In this book, you will learn how to use the beginner-friendly MicroPython language to write programs, and you’ll connect up hardware to make your Raspberry Pi Pico interact with the world around it. Using these skills, you can create your own electromechanical projects, whether for fun or to make your life easier.
Fully updated for Raspberry Pi Pico W and the latest version of MicroPython, this book shows you how to:
Get started with Raspberry Pi Pico and Pico W
Work with various electronic components
Create your own programmable electronic contraptions
Turn Raspberry Pi Pico W into a network-connected node for the Internet of Things
Link your Pico W to your smartphone, tablet, or another Pico W with Bluetooth Low Energy (BLE)
Whether you’re using Raspberry Pi Pico for a home project, industrial automation, or learning (or teaching!) electronics and programming, this book will show you how.

The Elektor Milliohmmeter Adapter uses the precision of a multimeter to measure very low resistance values. It is an adapter that converts a resistance into a voltage that can be measured with a standard multimeter.
The Elektor Milliohmmeter Adapter can measure resistances below 1 mΩ using a 4-wire (Kelvin) method. It is useful for locating short circuits on printed circuit boards (PCB).
The adapter features three measurement ranges – 1 mΩ, 10 mΩ, and 100 mΩ – selectable via a slide switch. It also includes onboard calibration resistors. The Elektor Milliohmmeter Adapter is powered by three 1.5 V AA batteries (not included).
