The Home Automation HAT uses only pluggable connectors. In addition, the latest release (V4.0 and up) has two new communication ports: 1-Wire and RS485.The card uses only 5 V power. On-board step-up power supply generates 12 V to power the 0-10 V analog outputs.A general purpose push-button, wired directly to a Raspberry Pi GPIO pin, can be used to shut down Raspberry Pi without a keyboard, or to force any output to a desired state. Ideal solution for your Raspberry Pi Home Automation projects. Read temperatures in up to 8 zones with analog inputs. Control your heating and cooling system with the 8 onboard relays. Use the 8 optically isolated digital inputs for your security system. Activate the hardware watchdog to monitor and power cycle the Raspberry Pi in case of software lockup. Control four-light systems with the four PWM open-drain outputs (you supply external power up to 24 V). Control four light dimmers using 0-10 V outputs. CompatibilityThe card is compatible with all Raspberry Pi versions from Zero to 4. It shares the I²C bus using only two of the Raspberry Pi’s GPIO pins to manage all eight cards. This feature leaves the remaining 24 GPIOs available for the user.Power RequirementsThe Home Automation card needs 5 V to operate and can be powered from Raspberry Pi or from its own pluggable connector. The onboard relay coils are also powered from the 5 V. An on-board 5V to 12V step-up power supply generates the voltage to drive the 0-10 V analog outputs. A local 3.3 V regulator powers the rest of the circuitry. The card needs 50 mA to operate with all relays off. Each relay needs up to 80 mA to turn on. RelaysThe 8 on-board relays have contacts brought out to heavy duty pluggable connectors, which make the card easy to use when multiple cards are stacked up. Relays are grouped in two sections of four relays each, with one common terminal and one N-O contact for each relay. Relays are rated 10 A/24 VDC and 250 VAC, but due to the board geometry limitation, the relays can switch only 3 A and 24 V, AC or DC. Status LEDs show when RELAYS are ON or OFF.Stacking Multiple CardsUp to eight Home Automation cards can be stacked on your Raspberry Pi. Each card is identified by jumpers you install to indicate the level in the stack. Cards can be installed in any order. The three position jumper on the upper right corner of the card selects the stack level.Features Eight relays with status LEDs and and N.O contacts Eight layer stackable Eight 12-bit A/D inputs, 250 Hz sample rate Four 13-bit DAC outputs (0-10 V dimmers) Four PWM 24 V/4 A open-drain outputs Eight optically isolated digital inputs Contact closure/Event counters up to 500 Hz Four Quadrature Encoder inputs 26 GPIOs from Raspberry Pi available 1-WIRE and RS485 communication ports Pluggable Connectors 26-16 AWG for all ports On-board hardware watchdog On-board resettable fuse Reverse power supply protection Brass stand-offs, screws and nuts included Hardware self-test with loop-back cable Open source hardware, schematics available 32-bit Processor running at 64 MHz Uses only I²C port (address 0x28..0x2f ), all GPIO pins available Specifications Power supply: Pluggable Connector, 5 V/3 A Power consumption: 50 mA (all relays off), 700 mA (all relays on) On board resettable fuse: 3 A Open Drain outputs: maximum 3 A, 24 V Relays 1,2,3,4,5,8: N-O contacts, 6 A/24 VAC or DC Relays 6,7: 3 A/24 VAC or DC Analog Inputs: Maximum input voltage: 3 V Input Impedance: 50 K?

Raspberry Pi 4 was welcomed by the Pi enthusiasts for the increased processing power. However, this came at a price. The RPi 4 can draw up to 3 Amps, which means it has to dissipate 15 W of power. Raspberry Pi cooling is a must. From the simplest passive heat sink, through elaborate fan blowers and even to an exotic water-cooled idea, many options are available.The Smart Fan has the form factor of the Raspberry Pi HAT. Its own tinny 32-bit processor receives commands from Raspberry Pi through the I²C interface. A step-up power supply converts the 5 V provided by Raspberry Pi to 12 V, ensuring precise speed control. Using pulse width modulation, it powers the fan just enough to maintain a constant temperature of the Raspberry Pi processor.The Smart Fan preserves all the GPIO pins, allowing any number of cards to be stacked on top of Raspberry Pi. If another add-on card has to dissipate power, a secondary Smart Fan can be added to the stack.DIN-Rail MountingTogether with multiple add-on cards, the Smart Fan can be installed on the DIN-Rail, for sturdy industrial applications.Stack Level JumperTwo Smart Fans can be installed on top of each Raspberry Pi. The assumption is that you have one more card in the stack which requires cooling. The bottom side of the Smart Fan has a jumper which needs to be installed on the second fan, in order for the Raspberry Pi to differentiate the two I²C addresses.Features 40 x 40 x 10 mm fan with 6 CFM airflow Step-up 12 V power supply for precise fan speed control PWM Controller modulates the fan to keep constant Pi temperature Draws less than 100 mA of power Stackable to itself, 2 fans can be added to Raspberry Pi Fully stackable allows adding other cards to Raspberry Pi Uses only I²C interface, leaves full use of all GPIO pins Super quiet and efficient Included Smart Han HAT 40 x 40 x 10 mm Fan with mounting Screws Mounting Hardware Downloads User's Guide Open Source Hardware Schematic 2D CAD Drawing Command line Python Libraries Node-Red Nodes

Most people are increasingly confronted with the applications of Artificial Intelligence (AI). Music or video ratings, navigation systems, shopping advice, etc. are based on methods that can be attributed to this field.The term Artificial Intelligence was coined in 1956 at an international conference known as the Dartmouth Summer Research Project. One basic approach was to model the functioning of the human brain and to construct advanced computer systems based on this. Soon it should be clear how the human mind works. Transferring it to a machine was considered only a small step. This notion proved to be a bit too optimistic. Nevertheless, the progress of modern AI, or rather its subspecialty called Machine Learning (ML), can no longer be denied.In this book, several different systems will be used to get to know the methods of machine learning in more detail. In addition to the PC, both the Raspberry Pi and the Maixduino will demonstrate their capabilities in the individual projects. In addition to applications such as object and facial recognition, practical systems such as bottle detectors, person counters, or a “talking eye” will also be created.The latter is capable of acoustically describing objects or faces that are detected automatically. For example, if a vehicle is in the field of view of the connected camera, the information 'I see a car!' is output via electronically generated speech. Such devices are highly interesting examples of how, for example, blind or severely visually impaired people can also benefit from AI systems.

De KrakenSDR is een fase-coherente software-defined radio met vijf RTL-SDR'sKrakenSDR is een vijfkanaals, RX-only, software-defined radio (SDR) gebaseerd op de RTL-SDR, en ontworpen voor fase-coherente toepassingen en experimenten. Fase-coherente SDR opent de deur naar een aantal zeer interessante toepassingen, waaronder radio richtingsbepaling, passieve radar en bundelvorming. U kunt de KrakenSDR ook gebruiken als vijf afzonderlijke radio's.KrakenSDR is een verbeterde versie van het vorige product, de KerberosSDR. Het biedt een vijfde ontvangstkanaal, automatische fase-coherenties ynchronisatiemogelijkheden, bias tee’s, een nieuw RF-ontwerp voor een schoner spectrum, USB Type-C-connectoren, een heavy-duty behuizing, verbeterde open source DAQ- en DSP-software, en een verbeterde Android-app voor het richtingzoeken.RTL-SDRDe KrakenSDR maakt gebruik van vijf aangepaste RTL-SDR circuits bestaande uit R820T2 en RTL2832U chips. De RTL-SDR is een bekende, goedkope software-defined radio (SDR), maar het samenvoegen van vijf hiervan en gebruik op dezelfde pc zal ze niet 'fase-coherent' maken; elke SDR zal signalen ontvangen op een iets andere fase- offset dan de anderen. Dit maakt het moeilijk of onmogelijk om een hoge mate van precisie te bereiken bij het meten van relaties tussen signalen die bij verschillende antennes aankomen.Om fase-coherentie te bereiken stuurt de KrakenSDR alle vijf de RTL-SDR-radio's aan met een enkel kloksignaal, en bevat hij interne kalibratiehardware waarmee de fase-relatie tussen de kanalen nauwkeurig kan worden gemeten en gecorrigeerd. Bovendien draagt het algemene ontwerp van de KrakenSDR bij om fase-stabiliteit te garanderen, met aandacht daarbij voor warmtebeheer, driverconfiguratie, voeding en beperking van externe interferentie.Kenmerken Vijfkanaals, fase-coherente RTL-SDR, allemaal geklokt op een enkele lokale oscillator Ingebouwde hardware voor automatische coherentie synchronisatie Automatische coherentie synchronisatie en beheer via meegeleverde Linux-software 24 MHz tot 1766 MHz tuning bereik (het standaard R820T2 RTL-SDR bereik, en mogelijk hoger met gehackte drivers) 4,5 V bias tee op elke poort Core DAQ- en DSP-software is open source en ontworpen om op een Raspberry Pi 4 te draaien Richtingzoeksoftware voor Android (gratis voor niet-commercieel gebruik) Toepassingen Het fysiek lokaliseren van een onbekende zender van belang (bijv. illegale of storende uitzendingen, ruisuitzendingen of gewoon als een curiositeit) HAM-radio-experimenten zoals radiovossenjachten of het monitoren van misbruik van repeaters Het volgen van eigendommen, dieren in het wild, of huisdieren buiten de netwerkdekking, door het gebruik van bakens met laag vermogen Het lokaliseren van noodbakens voor zoek- en reddingsteams Het lokaliseren van verloren schepen via VHF-radio Passieve radardetectie van vliegtuigen, boten en drones Monitoring van de verkeersdichtheid via passieve radar Beamvorming Interferometrie voor radioastronomie Specificaties Bandbreedte 2.56 MHz RX Kanalen 5 Frequentie bereik 24-1766 MHz Radio tuner 5x R820T2 Radio ADC 5x RTL2832U ADC bits 8-bits Oscillator stabiliteit 1 PPM Typical stroom verbruik 5 V/2.2 A (11 W) Type behuizing Heavy-duty CNC aluminum Afmetingen 177 x 112,3 x 25,9 mm Gewicht 560 g Inbegrepen 1x KrakenSDR (volledig gemonteerd en geïnstalleerd) met aluminium behuizing 1x Handleiding Vereist USB Type-C kabel 5 V/2.4 A USB Type-C voeding Antennes Raspberry Pi 4 (voor computer taken) Android-telefoon/tablet met mobiele hotspot-mogelijkheden (met richtingsbepaling) Downloads Wiki Android App
