The SDRplay RSPdx-R2 is a wideband full featured single-tuner 14-bit SDR receiver which covers the entire RF spectrum from 1 kHz to 2 GHz giving up to 10 MHz of spectrum visibility. It contains three antenna ports, two of which use SMA connectors and operate across the full 1 kHz to 2 GHz range and the third uses a BNC connector which operates up to 200 MHz. The RSPdx-R2 is an enhanced version of the RSPdx with further design improvements for use at frequencies below 2 MHz. Housed in a strong steel case, in addition to the functionality of the RSP1B, the RSPdx-R2 provides three software selectable antenna inputs and an external clock input. It offers excellent performance through HF and VHF frequencies all the way up to 2 GHz. The RSPdx-R2 also supports an "HDR mode" optimised for the demanding radio reception conditions below 2 MHz. The RSPdx-R2, when used in conjunction with SDRplay’s own software, introduces a special HDR (High Dynamic Range) mode for reception within selected bands below 2 MHz. HDR mode delivers improved intermodulation performance and fewer spurious responses for those challenging bands. Features Covers all frequencies from 1 kHz through VLF, LF, MW, HF, VHF, UHF and L-band to 2 GHz, with no gaps Receive, monitor and record up to 10 MHz of spectrum at a time Significantly improved noise performance below 1 MHz (i.e. for some MF, LF and below) Improved dynamic range below 2 MHz both in tuner mode and HDR mode HDR mode below 2 MHz giving overall dynamic range and selectivity advantages Software selectable choice of 3 antenna ports External clock input for synchronisation purposes, or connection to GPS reference clock for extra frequency accuracy Excellent dynamic range for challenging reception conditions Free use of Windows-based SDRuno software (check website for versions supported) Free use of SDRconnect SDR and server software for Windows, MacOS and Linux (Check website for versions supported) Multiplatform driver and API support including Windows, Linux, Mac and Raspberry Pi 4/5 Strong and growing software support network Calibrated S meter/RF power and SNR measurement with SDRuno (including datalogging to .CSV file capability) Documented API provided to allow demodulator or application development on multiple platforms Applications (Amateur) Shortwave radio listening Broadcast DXing (AM/FM/TV) Panadaptor Aircraft (ADS-B and ATC) Slow Scan TV Multi-amateur band monitoring WSPR & digital modes Weather fax (HF and satellite) Satellite monitoring Geostationary environmental satellites Trunked radio Utility and emergency service monitoring Fast and effective antenna comparison Applications (Industrial) Spectrum Analyser Surveillance Wireless microphone monitoring RF surveying IoT receiver chain Signal logging RFI/EMC detection Broadcast integrity monitoring Spectrum monitoring Power measurement Applications (Educational/Scientific) Teaching Receiver design Radio astronomy Passive radar Ionosonde Spectrum analyser Receiver for IoT sensor projects Antenna research Specifications Frequency Range 1 kHz – 2 GHz Antenna Connector SMA Antenna Impedance 50 Ohms Current Consumption (Typical) 190 mA @ >60 MHz (excl.

This bundle contains the popular Elektor Sand Clock for Raspberry Pi Pico and the new Elektor Laser Head Upgrade, offering even more options for displaying the time. Not only can you "engrave" the current time in sand, you can now alternatively write it on a glow-in-the-dark foil or create green drawings. Contents of the bundle Elektor Sand Clock for Raspberry Pi Pico (normal price: €50) Elektor Laser Head Upgrade for Sand Clock (normal price: €35) Elektor Sand Clock for Raspberry Pi (Raspberry Pi-based Eye Catcher) A standard sand clock just shows how time passes. In contrast, this Raspberry Pi Pico-controlled sand clock shows the exact time by "engraving" the four digits for hour and minute into the layer of sand. After an adjustable time the sand is flattened out by two vibration motors and everything begins all over again. At the heart of the sand clock are two servo motors driving a writing pen through a pantograph mechanism. A third servo motor lifts the pen up and down. The sand container is equipped with two vibration motors to flatten the sand. The electronic part of the sand clock consists of a Raspberry Pi Pico and an RTC/driver board with a real-time clock, plus driver circuits for the servo motors. A detailed construction manual is available for downloading. Features Dimensions: 135 x 110 x 80 mm Build time: approx. 1.5 to 2 hours Included 3x Precut acrylic sheets with all mechanical parts 3x Mini servo motors 2x Vibration motors 1x Raspberry Pi Pico 1x RTC/driver board with assembled parts Nuts, bolts, spacers, and wires for the assembly Fine-grained white sand Elektor Laser Head Upgrade for Sand Clock The new Elektor Laser Head transforms the Sand Clock into a clock that writes the time on glow-in-the-dark film instead of sand. In addition to displaying the time, it can also be used to create ephemeral drawings. The 5 mW laser pointer, with a wavelength of 405 nm, produces bright green drawings on the glow-in-the-dark film. For best results, use the kit in a dimly lit room. Warning: Never look directly into the laser beam! The kit includes all the necessary components, but soldering three wires is required. Note: This kit is also compatible with the original Arduino-based Sand Clock from 2017. For more details, see Elektor Magazine 1-2/2017 and Elektor Magazine 1-2/2018.

Practical Applications and Project with Arduino, ESP32, and RP2040 Immerse yourself in the fascinating world of control engineering with Arduino and ESP32! This book offers you a practical introduction to classic and modern control methods, including PID controllers, fuzzy logic, and sliding-mode controllers. In the first part, you will learn the basics of the popular Arduino controllers, such as the Arduino Uno and the ESP32, as well as the integration of sensors for temperature and pH measurement (NTC, PT100, PT1000, and pH sensor). You will learn how to use these sensors in various projects and how to visualize data on a Nextion TFT display. The course continues with an introduction to actuators such as MOSFET switches, H-bridges, and solid-state relays, which are used to control motors and actuators. You will learn to analyze and model controlled systems, including PT1 and PT2 control. The book focuses on the implementation of fuzzy and PID controllers for controlling temperature and DC motors. Both the Arduino Uno and the ESP32 are used. The sliding-mode controller is also introduced. In the second-to-last chapter, you will explore the basics of neural networks and learn how machine learning can be used on an Arduino. In the last chapter, there is a practical example of a fuzzy controller for feeding electricity into the household grid. This book is the perfect choice for engineers, students, and electronics engineers who want to expand their projects with innovative control techniques.
