  • Fan SHIM - Active Cooling for Raspberry Pi 4 - Elektor

    Pimoroni Fan SHIM - Active Cooling for Raspberry Pi 4

    When Raspberry Pi 4's system on chip (SoC) achieves a certain temperature, it lowers its operating speed to protect itself from harm. As a result, you don't get maximum performance from the single board computer. Fan SHIM is an affordable accessory that effectively eliminates thermal throttling and boosts the performance of RPi 4. It's quite easy to attach the fan SHIM to Raspberry pi: fan SHIM uses a friction-fit header, so it just slips onto your Pi's pins and it's ready to go, no soldering required! The fan can be controlled in software, so you can adjust it to your needs, for example, toggle it on when the CPU reaches a certain temperature etc. You can also program the LED as a visual indicator of the fan status. The tactile switch can also be programmed, so you can use it to toggle the fan on or off, or to switch between temperature-triggered or manual mode. Features 30 mm 5 V DC fan 4,200 RPM 0.05 m³/min air flow 18.6 dB acoustic noise (whisper-quiet) Friction-fit header No soldering required RGB LED (APA102) Tactile switch Basic assembly required Compatible with Raspberry Pi 4 (and 3B+, 3A+) Python library and daemon Pinout Scope of delivery Fan SHIM PCB 30 mm 5 V DC fan with JST connector M2.5 nuts and bolts Assembly The assembly is really simple and almost takes no time With the component side of the PCB facing upwards, push the two M2.5 bolts through the holes from below, then screw on the first pair of nuts to secure them and act as spacers. Push the fan's mounting holes down onto the bolts, with the cable side of the fan downwards (as pictured) and the text on the fan upwards. Attach with another two nuts. Push the fan's JST connector into the socket on Fan SHIM. Software With the help of Python library you can control the fan (on/off), RGB LED, and switch. You'll also find a number of examples that demonstrate each feature, as well as a script to install a daemon (a computer program that runs as a background process) that runs the fan in automatic mode, triggering it on or off when the CPU reaches a threshold temperature, with a manual override via the tactile switch.

  • FLIRC Case for Raspberry Pi 5 - Elektor

    FLIRC FLIRC case voor de Raspberry Pi 5

    Ontdek de perfecte behuizing voor jouw Raspberry Pi 5. FLIRC heeft de aan/uit-knop toegankelijk gemaakt en verbeterd met LED ondersteuning. Profiteer van het vertrouwde aluminium koellichaam dat inmiddels zo goed bevalt, genesteld tussen de twee matzwarte soft-touch paneeltjes, die goed bij uw entertainment systeem passen. Ingebouwde heatsink Dit is de eerste betaalbare Raspberry Pi behuizing gemaakt van aluminium. Het uitgangspunt voor FLIRC was dat de vorm niet belangrijker was dan de functie, dus gebruikten ze het aluminium van de behuizing meteen ook als koellichaam. Tevens is inbegrepen bij de case een thermisch kussentje, en 4 schroeven voor eenvoudige montage. Stabiliteit en toegang De FLIRC heeft rubberen voetjes om de behuizing wat omhoog te brengen, zodat deze bijvoorbeeld onder je tv kan worden geschoven. Naast het ingebouwde koellichaam zorgen kleine ventilatiesleuven aan de onderkant ervoor dat de Raspberry Pi koel blijft. De GPIO-pinnen zijn toegankelijk via de sleuf aan de onderkant van de behuizing, en om de SD-kaart te bereiken hoeft de case niet te worden gedemonteerd. Aan/uit-knop en LED ondersteuning De aan/uit-knop van de Raspberry Pi 5 wordt standaard ondersteund door de FLIRC behuizing. Ook de LED’s voor de diverse meldingen zijn duidelijk zichtbaar.

    Elektor Digital FreeCAD for Electronic Applications (E-book)

    Practical Introduction to 3D Modeling from Enclosure to Front Panel Embedding a vintage component, creating a professional looking home for a circuit board, or even designing a complex apparatus complete with a chassis – these and many other challenges turn into a stimulating pleasure with FreeCAD. Once you have internalized the basic processes, there are virtually no limits to your imagination. Starting to use a new software is never straightforward – especially with a tool as versatile as FreeCAD. Manageable, but at the same time easily usable individual components provide the starting point in this book. Putting these components together later results in assemblies. In the FreeCAD universe, a workable trajectory is demonstrated. The described procedure is illustrative so the examples are easily applied to custom tasks. The devices were made by the author and illustrated with photos. Creating a 3D design is requiring some effort but the initial investment pays off soon. Besides the impressive spatial representation of the projects, the extracted drawings yield a solid base for documentation and production. Extended FreeCAD capabilities like the unfolding of sheet metal parts enormously add to efficiency and pushes models forward into practical assembly. Soon you will definitely not want to do without FreeCAD!

    Deze bundel bevat: Boek: Get Started with the NXP FRDM-MCXN947 Development Board (normale prijs: € 40) NXP FRDM-MCXN947 Development Board (normale prijs: € 30) Boek: Get Started with the NXP FRDM-MCXN947 Development Board Projecten ontwikkelen op het gebied van connectiviteit, graphics, machine learning, motorbesturing en sensoren Dit (Engelse) boek gaat over het gebruik van de FRDM-MCXN947 Development Board, ontwikkeld door NXP Semiconductors. Het integreert de duale Arm Cortex-M33, werkend op maximaal 150 MHz. Ideaal voor industriële, IoT- en machine learning-toepassingen. Het beschikt over Hi-Speed USB, CAN 2.0, I³C en 10/100 Ethernet. Het bord bevat een ingebouwde MCU-Link debugger, FlexI/O voor LCD-besturing en dual-bank flash voor lees-terwijl-schrijftaken, met ondersteuning voor grote externe seriële geheugens. Een van de belangrijke kenmerken van het ontwikkelbord is de geïntegreerde eIQ Neutron Neural Processing Unit (NPU), wat gebruikers in staat stelt om AI-gebaseerde projecten te ontwikkelen. Het ontwikkelbord ondersteunt ook Arduino Uno header pins, waardoor het compatibel is met veel Arduino shields, een mikroBUS-connector voor MikroElektronika Click Boards en een Pmod-connector. Een van de voordelen van de FRDM-MCXN947 development board is dat het verschillende ingebouwde debug probes bevat, waarmee programmeurs hun programma's kunnen debuggen door direct met de MCU te communiceren. Met behulp van de debugger kunnen programmeurs stap voor stap door een programma gaan, breakpoints invoegen, variabelen bekijken en wijzigen, enzovoort. In het boek zijn veel werkende en geteste projecten ontwikkeld met behulp van de populaire MCUXpresso IDE en de SDK met verschillende sensoren en actuatoren. Het gebruik van de populaire CMSIS-DSP-bibliotheek wordt ook uitgelegd met verschillende veelgebruikte matrixbewerkingen. De in het boek verstrekte projecten kunnen zonder enige aanpassingen in veel toepassingen worden gebruikt. Alternatief kunnen lezers hun projecten baseren op de projecten die in het boek worden gegeven tijdens de ontwikkeling van hun eigen projecten.
