  •  -18% Elektor Dual DC LISN (150 kHz – 200 MHz)

    Eurocircuits Elektor Dual DC LISN (150 kHz - 200 MHz)

    Measuring conducted emission is the simplest and most affordable method of getting some indication of whether a design can meet EMI/EMC requirements. A Line Impedance Stabilization Network (LISN) is an indispensable part of an EMC pre-compliance test setup. In cooperation with Würth Elektronik, Elektor has developed a 5 µH, 50 Ω Dual DC LISN that supports voltages up to 60 V and currents up to 10 A. The instrument measures RF interferences on both channels (the power supply) by means of 5-μH blocking inductances. The internal 10-dB attenuation network – one in each channel – contains a 3rd-order high-pass filter with a cutoff frequency of 9 kHz to protect the input of instruments like a spectrum analyzer from potentially harmful DC voltages or low frequencies coming from the EUT (Equipment Under Test). Specifications RF path Channels 2 (with clamping diodes) Bandwidth 150 kHz – 200 MHz Inductance 5 μH || 50 Ω Internal attenuation 10 dB Connectors SMA DC path Max. current < 10 ADC Max. voltage < 60 VDC DC resistance < 2 x 70 mΩ PCB size 94.2 x 57.4 mm Connectors 4-mm banana Hammond enclosure Type 1590N Dimensions 121 x 66 x 40 mm Included 1x 4-layer PCB with all SMT parts fitted 1x pre-drilled enclosure with ready-printed front panel layout 5x gold-plated, insulated, 4-mm banana sockets, rated for 24 A, 1 kV 1x Hammond enclosure 1590N1, Aluminum (Die-Cast Alloy) More Info Project on Elektor Labs: Dual DC LISN for EMC pre-compliance testing Elektor 9-10/2021: EMC Pre-Compliance Test for Your DC-Powered Project (Part 1) Elektor 11-12/2021: EMC Pre-Compliance Test for Your DC-Powered Project (Part 2)

  • Elektor Special: Arduino Shields

    Elektor Special: Arduino Shields

    Make your project dreams come true: an odometer for the hamster wheel, a fully automatic control of your ant farm with web interface, or the Sandwich-O-Mat – a machine that toasts and grills sandwiches of your choice. With the Arduino and the DIY or Maker movement, not only did entry into microcontroller programming become child's play, but a second development also took place: Resourceful developers brought small boards – so-called shields or modules – to the market, which greatly simplified the use of additional hardware. The small modules contain all the important electronic parts to be connected to the microcontroller with a few plug-in cables, eliminating the need for a fiddly and time-consuming assembly on the plug-in board. In addition, it is also possible to handle tiny components that do not have any connecting legs (so-called SMDs).

  • Sand Clock Kit (based on Raspberry Pi Pico)

    Elektor Labs Sand Clock Kit (based on Raspberry Pi Pico)

    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: 1.5 to 2 hours approx. 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 Labs Elektor Tapir E-Smog Detector Kit

    Ultrasensitive wideband magnetic/electromagnetic field detector This ultra sensitive wideband “E-smog” detector adds two senses to help you track down noise that’s normally inaudible. TAPIR also makes a great project to build since the enclosure is the PCB proper. TAPIR detects electric as well as magnetic fields at high frequencies. The PCB is ingenuously designed to double as a shielded case. Each of the two antennas that can be connected to TAPIR is optimized for one type of field. Magnetic fields are detected with a ferrite-cored coil, and electric fields with a rod antenna, which is easily constructed from a length of stiff wire. Using TAPIR is dead easy. Connect the headphones, the selected antenna and switch on. Move the antenna around any suspect area and you’ll hear different types of noise and noise levels with each electrical device, depending on the type and frequency of the emitted field.

  •  -14% Elektor Super Servo Tester kit

    Elektor Labs Elektor Super Servo Tester kit

    The Elektor Super Servo Tester can control servos and measure servo signals. It can test up to four servo channels at the same time. The Super Servo Tester comes as a kit. All the parts required to assemble the Super Servo Tester are included in the kit. Assembling the kit requires basic soldering skills. The microcontroller is already programmed. The Super Servo Tester features two operating modes: Control/Manual and Measure/Inputs. In Control/Manual mode the Super Servo Tester generates control signals on its outputs for up to four servos or for the flight controller or ESC. The signals are controlled by the four potentiometers. In Measure/Inputs the Super Servo Tester measures the servo signals connected to its inputs. These signals may come from for instance an ESC, a flight controller, or the receiver or another device. The signals are also routed to the outputs to control the servos or the flight controller or ESC. The results are shown on the display.

Elektor products are not kits like the others. Elektor circuits are sometimes quite complex. They are designed so that their assembly presents as few problems as might reasonably be expected. If the kits developed by Elektor are not particularly difficult to build, it is precisely because they are designed from A to Z to be replicated at home by many readers with equally varying levels and skills in electronics.
