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)
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.

A Practical Introduction to Embedded Systems with the ESP32
This course is designed for readers who are new to embedded systems and looking for a structured, example-driven way to get started. If you’ve explored general-purpose electronics or Arduino-based materials but found them too broad or lacking in practical guidance, this course offers a more focused alternative.
Using the "ESP32 by Example Kit" (EEK) – a compact and affordable set of components featuring LEDs, sensors, an OLED display, and a motion processor – you’ll work with a consistent hardware setup throughout the course. Once assembled, the EEK stays mostly unchanged, allowing you to concentrate on learning and experimentation without constant reconfiguration.

Understanding and programming the ESP32 microcontroller
Writing and deploying code with the Arduino IDE
Exploring cyber-physical systems, culminating in basic drone control
No prior experience with Arduino or embedded development is required. Each section features hands-on examples and mini-projects designed to reinforce key concepts and inspire deeper exploration. By the end of the course, you’ll be able not only to reproduce the book’s examples but also to build on them with your own ideas and applications.
Whether you're interested in embedded programming, interactive systems, or introductory drone control, this course provides a clear and practical path to getting started.

The Elektor Zener Diode Tester is essentially a constant-current source that can be switched in steps from 1 to 50 mA. It can be used to test Z-diodes up to a maximum of 54 V. Thanks to a 60-V step-up converter, the device can be powered by the usual 5 to 12 V.
The principle of this tester is straightforward. A Z-diode or other DUT (device under test, such as an LED) is biased by an adjustable current source. The voltage across the DUT can be measured with a multimeter. The voltage of most (small) Z-diodes is specified at a current of 5 mA. Depending on the application, the voltage at other currents can also be of interest. That is why six current settings are available: 1, 2, 5, 10, 20, and 50 mA. LEDs are often specified at a current of 20 mA.
What can be tested is:
Whether a Z-diode is defective (short circuit or high impedance).
Whether a Z-diode exhibits the correct Z-voltage.
How a Z-voltage changes with different currents.
What exact voltage is present at an integrated voltage reference.
Whether LEDs in a series chain differ in brightness (hence the 20 mA current).
What the current gain is for different base currents in (power) transistors.
The kit contains all parts listed in the bill of materials including PCB and enclosure.

Arduino-compatible, ESP32-controlled, 2-wheeled Balancing Robot
The Elektor Mini-Wheelie is an experimental autonomous self-balancing robot platform. Based on an ESP32-S3 microcontroller, the self-balancing robot is fully programmable using the Arduino environment and open-source libraries. Its wireless capabilities allow it to be controlled remotely over Wi-Fi, Bluetooth or ESP-NOW or to communicate with a user or even another robot.
An ultrasonic transducer is available for detecting obstacles. Its color display can be used for displaying cute facial expressions or, for the more down-to-earth users, cryptic debug messages.
The robot comes as a neat kit of parts that you must assemble yourself. Everything is included, even a screwdriver.
Note: The Mini-Wheelie is an educational development platform intended for learning, experimentation, and robotics development. It is not classified as a toy for children, and its features, documentation, and intended audience reflect this purpose. The product is aimed at students, educators, and developers who wish to explore robotics, programming, and hardware integration in an educational setting.

Documentation
This complete ESP32 microcontroller programming course features a textbook, a component kit, hands-on projects, and a comprehensive online course with simulations. It is ideal for step-by-step learning of embedded systems programming with Arduino using a practical, hands-on approach.
A Practical Introduction to Embedded Systems with the ESP32
This course is designed for people who are new to embedded systems and looking for a structured, example-driven way to get started.
A kit of parts comprising LEDs and resistors, switches, sensors and actuators, displays, a breadboard and wires, and more is included. These are used in the course to illustrate example applications.
No prior experience with Arduino or embedded development is required. Each section features hands-on examples and mini projects designed to reinforce key concepts and inspire deeper exploration. By the end of the course, you’ll be able not only to reproduce the examples but also to build on them with your own ideas and applications.
