Dit boek gaat over de Raspberry Pi, en over het programmeren in C. De programmeertaal C en het besturingssysteem Linux (Raspbian) passen uitstekend bij elkaar. Alles wat we nodig hebben om in C te programmeren wordt meegeleverd met het besturingssysteem van de Raspberry Pi. In dit boek leert u hoe C gebruikt wordt met de Raspberry Pi, en krijgt u een overzicht van de taal. WiringPi is een softwarebibliotheek voor de Raspberry Pi waarmee C hardware-uitbreidingen kan benaderen. Die bibliotheek wordt gebruikt om sensoren uit te lezen en om extra hardware aan te sturen. U gaat experimenteren met LED’s en schakelaars, met motoren, met geluid en met sensoren voor temperatuur, luchtdruk, en luchtvochtigheid. Met een Linux-systeem kunt u een webserver maken, inclusief interactieve websites met PHP en WiringPi. Daarom is ook een beknopt overzicht van HTML en PHP in het boek opgenomen. In de voorbeelden worden sensoren via het web uitgelezen en worden apparaten bestuurd. In het laatste voorbeeld wordt een temperatuurlogger gemaakt. Die meet elk kwartier de temperatuur. Een tabel met de meetwaarden kan via het web worden uitgelezen. Alle voorbeeldprogramma’s kunnen worden gedownload van de website van Elektor.

The Seeed Studio RF Explorer 3G Combo is a handheld digital spectrum analyzer and an affordable tool for working across a wide range of popular frequency bands. It is based on a highly integrated frequency synthesizer and a double-balanced mixer, providing high performance, compact dimensions, low power consumption, and excellent value. Designed for both indoor and outdoor use, the RF Explorer 3G Combo can also be connected to a PC via a standard Mini-USB 2.0 connector for additional functionality. This model combines a WSUB1G base unit with an RFEMWSUB3G expansion module, supplied fully assembled and tested. It features two SMA connectors and includes two antennas: a dual-band 144/430 MHz telescopic antenna for sub-GHz frequencies and a helical whip antenna for the 2.4 GHz band. Additional frequency-specific antennas may be required for optimal performance in certain supported frequency ranges. This combination provides the wide frequency coverage of the WSUB3G module together with the high sensitivity and fast response of the WSUB1G unit in the commonly used sub-1 GHz frequency range.

This kit includes iFixit's widest assortment of bits, complete with every driver head you’ll need to tackle any repair or DIY project. It includes standard bits like Phillips and Flathead in a full range of sizes to handle everything from precision electronics repair to home DIY projects. And it wouldn’t be an iFixit bit set if it didn’t include all the exotic bits from Pentalobes for Apple iPhone and MacBook repair to Gamebits for your vintage Nintendo consoles. All of the next-gen bit sets have been re-designed in order to maximize convenience and usability. The bit set lid is held in place with magnets to increase product lifespan (no more broken hinges or clasps) and also mounts to the back of the bit set case to keep it out of the way while you do your work. If you need help keeping your screws and parts organized, you can use the lid’s integrated sorting tray. The 4 mm bits have been adjusted and have now a longer neck for a deeper and more precise reach.

The 8x10" iFixit Magnetic Project Mat catches and securely holds screws as you pull them out of a device. Now you can stop worrying about keeping track of all the loose screws and focus on your repair. Screws and small parts will remain right where you left them. For laptops with hundreds of screws, use the whole mat as a screw guide and keep careful location notes. Included is a pen — made by Staedtler, producer of top-of-the-line pens and pencils for artists and architects — that was specially designed for the Project Mat. The Lumocolor Correctable pen resists smears and won't wipe away with a casual brush of your hand. When your repair is complete, use the eraser tip or a dry cloth to wipe the ink away clean. Kenmerken Organize all your small parts while you work on a device. The dry-erase surface lets you keep notes and location sketches. Reduces reassembly time by up to 40% while preventing errors.
