The active cooler provides an alternative cooling solution for users who wish to use their Raspberry Pi 5 under sustained heavy load without a case. It combines a large metal heatsink with a variable-speed blower, again powered and controlled via the fan connector, and attaches to the Raspberry Pi 5 via sprung pins into a pair of mounting holes.

Although much classical HF and mobile equipment is still in use by many amateurs, the use of computers and digital techniques has now become very popular among amateur radio operators. Nowadays, anyone can purchase a Raspberry Pi computer and run almost all amateur radio software on the ‘RPi’, which is slightly bigger than the size of a credit card.
The RTL-SDR devices have become very popular among hams 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, an RPi computer, a USB-baased external audio input-output adapter, and software installed on the Pi. With such a simple setup it is feasible to receive signals from around 24 MHz to over 1.7 GHz. With the addition of a low-cost upconverter device, an RTL-SDR can easily and effectively receive the HF bands.
This book is aimed at amateur radio enthusiasts, electronic engineering students, and anyone interested in learning to use the Raspberry Pi to build electronic projects. The book is suitable for the full range of beginners through old hands at ham radio. Step-by-step installation of the operating system is described with many details on the commonly used Linux commands. Some knowledge of the Python programming language is required to understand and modify the projects given in the book. Example projects developed in the book include a station clock, waveform generation, transistor amplifier design, active filter design, Morse code exerciser, frequency counter, RF meter, and more. The block diagram, circuit diagram, and complete Python program listings are given for each project, including the full description of the projects.
Besides wide coverage of RTL-SDR for amateur radio, the book also summarizes the installation and use instructions of the following ham radio programs and software tools you can run on your Raspberry Pi: TWCLOCK, Klog, Gpredict, FLDIGI, DIRE WOLF, xcwcp, QSSTV, LinPsk, Ham Clock, CHIRP, xastir, and CQRLOG.
Designed for environmental monitoring, Enviro+ lets you measure air quality (pollutant gases and particles*), temperature, pressure, humidity, light, and noise level. Enviro+ is an affordable alternative to environmental monitoring stations that can cost tens of thousands of pounds and, best of all, it's small and hackable and lets you contribute your data to citizen science efforts to monitor air quality via projects like Luftdaten. Features BME280 temperature, pressure, humidity sensor (datasheet) LTR-559 light and proximity sensor (datasheet) MICS6814 analog gas sensor (datasheet) ADS1015 analog to digital converter (ADC) (datasheet) MEMS microphone (datasheet) 0.96' colour LCD (160 × 80) pHAT-format board Fully-assembled Compatible with all 40-pin header Raspberry Pi models Pinout Python library Citizen science air quality monitoring This board was developed in collaboration with the University of Sheffield, with the aim of letting you contribute real-time air quality data from your local area to open data projects like Luftdaten. Devices like Enviro+ allow fine-grained, detailed datasets that let us see shifts in air quality through time and across different areas of cities. The dataset gets better in quality every time an additional The more devices that contribute data, the better quality the dataset becomes. Particulate matter (PM) is made up of tiny particles that are a mix of sizes and types, like dust, pollen, mould spores, smoke particles, organic particles and metal ions, and more. Particulates are much of what we think of as air pollution. The analog gas sensor can be used to make qualitative measurements of changes in gas concentrations, so you can tell broadly if the three groups of gases are increasing or decreasing in abundance. Without laboratory conditions or calibration, you won't be able to say 'the concentration of carbon monoxide is n parts per million', for example. Temperature, air pressure and humidity can all affect particulate levels (and the gas sensor readings) too, so the BME280 sensor on Enviro+ is really important to understanding the other data that Enviro+ outputs. You can implement Enviro+ in IoT applications as well. By connection it to Alexa you can get information about the temperature and humidity of the air by simply asking, or there's also an option to set up a trigger action with IFTTT that turns your Philips Hue lights on when the light level drops below a certain level etc. Software With the Python library you can control control all the parts of your Enviro+. There's a bunch of examples for each of the individual parts, an all-in-one example that shows you the data from Enviro+'s sensors in a visual way.

This anodised aluminium heatsink case will protect your Raspberry Pi 4 and give you very effective passive cooling. It's great in cases where you want completely silent cooling, for instance, if you're building a home media center. The scope of delivery includes a thermal pad to provide thermal contact between the CPU and top case, and a handy Allen key and set of hex bolts to attach the case together. The case gives you access to all of the ports, pins, and connectors. Features Anodised aluminium top and bottom case Heatsink fins Thermal pad Hex bolts and Allen key included Access to all ports, pins, and connectors Compatible with Raspberry Pi 4 Assembly Assembling your heatsink case is pretty easy and should only take a couple of minutes. The first, and most important thing is to make sure that your Pi is powered off and unplugged before you fit the case. Take one of the thermal pads and peel the protective films off both sides of it (there's a white film and an easy-to-miss clear film on the other side. Stick the thermal pad onto your Pi's CPU (the metal square nearest the middle of the PCB). Sticking the thermal pad to the CPU first is a much better way to position it correctly than trying to stick it to the case. Only use one thermal pad with the Raspberry Pi 4. Position the top case and then, holding it in place, flip the whole thing over and position the bottom case on the underside of your Pi. Use the four hex bolts and allen key to secure the case. Notes The case is metal and hence conductive, so be careful not to short any components on it, and ensure that your RPi is powered off and unplugged when fitting the case It may be obvious, but the case will get hot in use Dimensions: 87 × 56 × 25.5 mm

Het boek “Sensoren aan de Raspberry Pi” richt zich tot iedereen die zich wil verdiepen in een Raspberry Pi 2 of 3 in combinatie met Windows 10 IoT Core. Dit besturingssysteem biedt samen met een RPi weliswaar veel rekenkracht, maar voor de communicatie met de buitenwereld zijn nog externe modules en sensoren nodig. Daartoe wordt in dit boek gebruik gemaakt van een sensor-kit met 35 modules die nog geen 60 euro kost.Auteur Florian Schäffer begint zijn boek met de introductie van de Raspberry Pi en hij beschrijft welke hardware u nodig hebt om met de RPi te kunnen werken. Dan volgt een eerste kennismaking met Windows 10 IoT Core. Daarna wordt dieper ingegaan op het gebruik van Visual Studio 2015 en worden de eerste programmeervoorbeelden beschreven. Ook wordt uitgelegd hoe een MySQL-databank kan worden aangestuurd via een app en hoe de Rpi2 als webserver kan worden ingezet.In het tweede deel worden de sensoren stuk voor stuk beschreven met hun eigenschappen en worden er veel toepassingsvoorbeelden gegeven. De source-codes van de programma’s zijn als download bij het boek beschikbaar. Tot slot wordt nog aandacht besteed aan het gebruik van druktoetsen en schakelaars, en het werken met digitale uitgangen en analoge ingangen.

When you experiment with the Raspberry Pi on a regular basis and you connect a variety of external hardware to the GPIO port via the header you may well have caused some damage in the past. The Raspberry Pi Buffer Board is there to prevent this! The board is compatible with Raspberry Pi Zero, 3, 4, 5 and 400.
All 26 GPIOs are buffered with bi-directional voltage translators to protect the Raspberry Pi when experimenting with new circuits. The PCB is intended to be inserted in the back of Raspberry Pi< 400. The connector to connect to the Raspberry Pi is a right angled 40-way receptacle (2x20). The PCB is only a fraction wider. A 40-way flat cable with appropriate 2x20 headers can be connected to the buffer output header to experiment for instance with a circuit on a breadboard or PCB.
The circuit uses four TXS0108E ICs by Texas Instruments. The PCB can also be put upright on a Raspberry Pi 3 or newer.
