Elektor Digital Building a High-Tech Alarm System with Raspberry Pi (E-book)
This book discusses the basic components of any alarm system. All alarm systems have two basic functions. First, they monitor their environment looking for a change such as a door or window opening or someone moving about in the room. Second, they alert the legal owner or user to this change. The system described in this book uses a scanning type software to detect intruders. It behaves like a guard dog, pacing up and down the fence line on the lookout for either an intruder or a familiar person. If you have an alarm key, you can disarm the system and enter. With the scanning method, the software is easy to write and explain. It can scan eight alarm zones plus two special fire zones in about one second. You don’t have to be an electrical engineer to install an alarm system, just a decent carpenter, painter, and plasterer! Because this alarm system runs on 12 volts, you don’t have to be a licensed electrician either to install it. The alarm system presented here uses Python software on the Raspberry Pi combined with some elementary electronic circuits. The code described in the book, as well as CAD files and a bill of materials for the alarm panel, are available for free downloading. The book provides the reader with examples of typical configurations coming straight from the author‘s experience. After reviewing the hardware components typically used in common alarm systems, the author shows how to plan one yourself. To implement a modular alarm, no matter if it is for a single house or for a business or restaurant, the book shows how to skillfully combine a Raspberry Pi with small auxiliary electronic circuits. These are not installation instructions but food for thought that will enable readers to find a solution to their needs.

Pi Modules DiP-Pi Pico PIoT for Raspberry Pi Pico
The DiP-Pi PIoT is an Advanced Powered, WiFi connectivity System with sensors embedded interfaces that cover most of possible needs for IoT application based on Raspberry Pi Pico. It can supply the system with up to 1.5 A @ 4.8 V delivered from 6-18 VDC on various powering schemes like Cars, Industrial plant etc., additionally to original micro-USB of the Raspberry Pi Pico. It supports LiPo or Li-Ion Battery with Automatic Charger as also automatic switching from cable powering to battery powering or reverse (UPS functionality) when cable powering lost. Extended Powering Source (EPR) is protected with PPTC Resettable fuse, Reverse Polarity, as also ESD.The DiP-Pi PIoT contains Raspberry Pi Pico embedded RESET button as also ON/OFF Slide Switch that is acting on all powering sources (USB, EPR or Battery). User can monitor (via Raspberry Pi Pico A/D pins) battery level and EPR Level with PICO’s A/D converters. Both A/D inputs are bridged with 0402 resistors (0 OHM) therefore if for any reason user needs to use those Pico pins for their own application can be easy removed. The charger is automatically charging connected battery (if used) but in addition user can switch charger ON/OFF if their application needs it.DiP-Pi PIoT can be used for cable powered IoT systems, but also for pure Battery Powered System with ON/OFF. Each powering source status is indicated by separate informative LEDs (VBUS, VSYS, VEPR, CHGR, V3V3).User can use any capacity of LiPo or Li-Ion type; however, must take care to use PCB protected batteries with max discharge current allowed of 2 A. The embedded battery charger is set to charge battery with 240 mA current. This current is set by resistor so if user need more/less can himself to change it. The DiP-Pi PIoT is also equipped with WiFi ESP8266 Clone module with embedded antenna. This feature open a wide range of IoT applications based on it.In Addition to all above features DiP-Pi PIoT is equipped with embedded 1-wire, DHT11/22 sensors, and micro–SD Card interfaces. Combination of the extended powering, battery, and sensors interfaces make the DiP-Pi PIoT ideal for IoT applications like data logger, plants monitoring, refrigerators monitoring etc.DiP-Pi PIoT is supported with plenty of ready to use examples written in Micro Python or C/C++.SpecificationsGeneral Dimensions 21 x 51 mm Raspberry Pi Pico pinout compatible Independent Informative LEDs (VBUS, VSYS, VEPR, CHGR, V3V3) Raspberry Pi Pico RESET Button ON/OFF Slide Switch acting on all powering sources (USB, EPR, Battery) External Powering 6-18 VDC (Cars, Industrial Applications etc.) External Power (6-18 VDC) Level Monitoring Battery Level Monitoring Inverse Polarity Protection PPTC Fuse Protection ESD Protection Automatic Battery Charger (for PCB protected LiPo, Li-Ion – 2 A Max) Automatic/User Control Automatic Switch from Cable Powering to Battery Powering and reverse (UPS Functionality) Various powering schemes can be used at the same time with USB Powering, External Powering and Battery Powering 1.5 A @ 4.8 V Buck Converter on EPR Embedded 3.3 V @ 600 mA LDO ESP8266 Clone WiFi Connectivity ESP8266 Firmware Upload Switch Embedded 1-wire Interface Embedded DHT-11/22 Interface Powering Options Raspberry Pi Pico micro-USB (via VBUS) External Powering 6-18 V (via dedicated Socket – 3.4/1.3 mm) External Battery Supported Battery Types LiPo with protection PCB max current 2A Li-Ion with protection PCB max current 2A Embedded Peripherals and Interfaces Embedded 1-wire interface Embedded DHT-11/22 Interface Micro SD Card Socket Programmer Interface Standard Raspberry Pi Pico C/C++ Standard Raspberry Pi Pico Micro Python Case CompatibilityDiP-Pi Plexi-Cut CaseSystem Monitoring Battery Level via Raspberry Pi Pico ADC0 (GP26) EPR Level via Raspberry Pi Pico ADC1 (GP27) Informative LEDs VB (VUSB) VS (VSYS) VE (VEPR) CH (VCHR) V3 (V3V3) System Protection Direct Raspberry Pi Pico Hardware Reset Button ESD Protection on EPR Reverse Polarity Protection on EPR PPTC 500 mA @ 18 V fuse on EPR EPR/LDO Over Temperature protection EPR/LDO Over Current protection System Design Designed and Simulated with PDA Analyzer with one of the most advanced CAD/CAM Tools – Altium Designer Industrial Originated PCB Construction 2 ozcopper PCB manufactured for proper high current supply and cooling 6 mils track/6 mils gap technology 2 layers PCB PCB Surface Finishing – Immersion Gold Multi-layer Copper Thermal Pipes for increased System Thermal Response and better passive cooling Downloads Datasheet Manual

Elektor Publishing Raspberry Pi 5 for Radio Amateurs
Program and Build Raspberry Pi 5 Based Ham Station Utilities with the RTL-SDR The RTL-SDR devices (V3 and V4) have gained popularity among radio amateurs because of their very low cost and rich features. A basic system may consist of a USB based RTL-SDR device (dongle) with a suitable antenna, a Raspberry Pi 5 computer, a USB based external audio input-output adapter, and software installed on the Raspberry Pi 5 computer. With such a modest setup, it is possible to receive signals from around 24 MHz to over 1.7 GHz. This book is aimed at amateur radio enthusiasts and electronic engineering students, as well as at anyone interested in learning to use the Raspberry Pi 5 to build electronic projects. The book is suitable for both beginners through experienced readers. Some knowledge of the Python programming language is required to understand and eventually modify the projects given in the book. A block diagram, a circuit diagram, and a complete Python program listing is given for each project, alongside a comprehensive description. The following popular RTL-SDR programs are discussed in detail, aided by step-by-step installation guides for practical use on a Raspberry Pi 5: SimpleFM GQRX SDR++ CubicSDR RTL-SDR Server Dump1090 FLDIGI Quick RTL_433 aldo xcwcp GPredict TWCLOCK CQRLOG klog Morse2Ascii PyQSO Welle.io Ham Clock CHIRP xastir qsstv flrig XyGrib FreeDV Qtel (EchoLink) XDX (DX-Cluster) WSJT-X The application of the Python programming language on the latest Raspberry Pi 5 platform precludes the use of the programs in the book from working on older versions of Raspberry Pi computers.
