Elektor Labs Elektor US-Style Siren Kit
A great way to explain the workings of an electronic circuit is to position the discrete parts on the board exactly as in the schematic. Press the button and this 'Elektor Classic' responds with 1 of 3 siren sounds: police, ambulance, or fire brigade. The kit is composed of through-hole parts only and includes a wooden desktop stand. A full explanation of the circuit operation appears on the back of the circuit board.

Elektor Labs Elektor Cloc 2.0 Kit
ESP32-based Alarm Clock connects to Timeserver and controls Radio & TV Cloc is an easy to build alarm clock without SMT parts. It has a double 7-segment retro display with variable brightness. One display shows the current time, the other the alarm time. Cloc connects to a Wi-Fi network, so it can access a timeserver somewhere on the planet. It can connect using DHCP or with a fixed IP address. An optional DS3231-based battery-backed real-time clock (RTC) module (not included in the kit) can be added to keep time in case of network problems. The built-in web server shows the time, allows setting the alarms and lets you adjust the clock’s parameters. The optimized graphical HTML interface works on most standard browsers and handheld devices. Specifications Based on an ESP32-Pico-Kit. Two independent 7-segment displays for the time of day and the alarm time. The time is set automatically by connecting to an online timeserver. Alarm time for each day of the week. Alarm output: buzzer and infrared code for e.g. radio, hi-fi system or TV. Two push-buttons for interacting with the device. Integrated web server for remote configuration via Wi-Fi. All settings are saved in EEPROM. Open-source software written for Arduino. Over-the-Air (OTA) mode allows updating the firmware remotely. Optional DS3231-based real-time clock (RTC) module (not included). Included PCB All components ESP32-Pico-Kit V4 (valued at €20) Hammond IR Red Translucent PC Enclosure (valued at €15) Links Cloc – Alarm Clock 2.0

SparkFun SparkFun Thing Plus Matter (MGM240P)
The SparkFun Thing Plus Matter is the first easily accessible board of its kind that combines Matter and SparkFun’s Qwiic ecosystem for agile development and prototyping of Matter-based IoT devices. The MGM240P wireless module from Silicon Labs provides secure connectivity for both 802.15.4 with Mesh communication (Thread) and Bluetooth Low Energy 5.3 protocols. The module comes ready for integration into Silicon Labs' Matter IoT protocol for home automation.What is Matter? Simply put, Matter allows for consistent operation between smart home devices and IoT platforms without an Internet connection, even from different providers. In doing so, Matter is able to communicate between major IoT ecosystems in order to create a single wireless protocol that is easy, reliable, and secure to use.The Thing Plus Matter (MGM240P) includes Qwiic and LiPo battery connectors, and multiple GPIO pins capable of complete multiplexing through software. The board also features the MCP73831 single-cell LiPo charger as well as the MAX17048 fuel gauge to charge and monitor a connected battery. Lastly, a µSD card slot for any external memory needs is integrated.The MGM240P wireless module is built around the EFR32MG24 Wireless SoC with a 32-bit ARM Cortext-M33 core processor running at 39 MHz with 1536 kb Flash memory and 256 kb RAM.

Elektor Special: Power Supplies and Batteries
Whatever the methods or even then financial means you have to make your circuits work, the power supply should rank high if not Number One in your considerations. The design block simply called “power supply” is hugely underrated both in electronics creation and repair. Yet, the “PSU” has enormous diversity and comes in wildly differing guises like AC/DC, generator, battery (rechargeable or not), PV panel, benchtop, linear or switch-mode, to mention but a few. The output ranges are also staggering like nano-amps to kiloamps and the same for voltages.This special covers the features and design aspects of power supplies.ContentsBasics Battery ManagementWhat to be aware of when using (Lithium) batteries.

Cambridge University Press The Art of Electronics (3rd Edition)
At long last, here is the thoroughly revised and updated third edition of the hugely successful The Art of Electronics. It is widely accepted as the best single authoritative book on electronic circuit design.In addition to new or enhanced coverage of many topics, the third edition includes 90 oscilloscope screenshots illustrating the behavior of working circuits, dozens of graphs giving highly useful measured data of the sort that is often buried or omitted in datasheets but which you need when designing circuits, and 80 tables (listing some 1650 active components), enabling intelligent choice of circuit components by listing essential characteristics (both specified and measured) of available parts.The new Art of Electronics retains the feeling of informality and easy access that helped make the earlier editions so successful and popular. It is an indispensable reference and the gold standard for anyone, student or researcher, professional or amateur, who works with electronic circuits. Over 450,000 copies sold of first and second editions The leading practical guide to circuit design Fully up to date and packed with valuable advice About the authorsPaul Horowitz is a Research Professor of Physics and of Electrical Engineering at Harvard University, where in 1974 he originated the Laboratory Electronics course from which emerged The Art of Electronics. In addition to his work in circuit design and electronic instrumentation, his research interests have included observational astrophysics, x-ray and particle microscopy, and optical interferometry. He is one of the pioneers of the search for intelligent life beyond Earth (SETI). He is the author of some 200 scientific articles and reports, has consulted widely for industry and government, and is the designer of numerous scientific and photographic instruments.Winfield Hill is by inclination an electronics circuit-design guru. After dropping out of the Chemical Physics graduate program at Harvard University, and obtaining an EE degree, he began his engineering career at Harvard’s Electronics Design Center. After 7 years of learning electronics at Harvard he founded Sea Data Corporation, where he spent 16 years designing instruments for Physical Oceanography. In 1988 he was recruited by Edwin Land to join the Rowland Institute for Science. The institute subsequently merged with Harvard University in 2003. As director of the institute’s Electronics Engineering Lab he has designed some 500 scientific instruments. Recent interests include high-voltage RF (to 15kV), high-current pulsed electronics (to 1200A), low-noise amplifiers (to sub-nV and pA), and MOSFET pulse generators.
