Elektor Labs Elektor ±40 V Linear Voltage Regulator Kit
An alternative power supply for the Elektor Fortissimo-100 Power Amplifier For those who object to a switch-mode power supply for the Fortissimo-100 Power Amplifier, this kit yields a linear, symmetrical, voltage regulator marked by low dropout voltage, high output current, and excellent stability – all obtained from discrete components. Bearing in mind that nearly all high-performance audio power amplifiers benefit from a stabilized power supply, this linear power supply is specifically designed for a symmetrical output voltage of ±40 V and peak currents of 13 A (15 A peak achievable). As an example, the average current drawn by a Fortissmo-100 amp driving a 3 Ω load is 4 A per regulator. Specifications Input voltage range 52 V DC (low power usage) to 43 V DC Output voltage range approx. 38.9 V DC to 41.4 V DC (theoretically)38.6 V DC to 41.1 V DC (measured) Dropout voltage at 6 A 42 V Dropout voltage at 9.5 A 43 V Dropout voltage at 13.5 A 44 V Max. current 15 A peak (half sinewave), 4.8 A (average) SOAR protection 15 A at 45 V DC in Ripple rejection >60 dB (@ 5 A DC load) No-load input current 27 mA (@ 52 V DC input) Included PCB All parts including heatsinks

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.

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 Labs Elektor Cloc 2.0 Kit
ESP32-based Alarm Clock connects to Timeserver and controls Radio & TV Cloc is an easy to build alarm clock without SMT parts. It has a double 7-segment retro display with variable brightness. One display shows the current time, the other the alarm time. Cloc connects to a Wi-Fi network, so it can access a timeserver somewhere on the planet. It can connect using DHCP or with a fixed IP address. An optional DS3231-based battery-backed real-time clock (RTC) module (not included in the kit) can be added to keep time in case of network problems. The built-in web server shows the time, allows setting the alarms and lets you adjust the clock’s parameters. The optimized graphical HTML interface works on most standard browsers and handheld devices. Specifications Based on an ESP32-Pico-Kit. Two independent 7-segment displays for the time of day and the alarm time. The time is set automatically by connecting to an online timeserver. Alarm time for each day of the week. Alarm output: buzzer and infrared code for e.g. radio, hi-fi system or TV. Two push-buttons for interacting with the device. Integrated web server for remote configuration via Wi-Fi. All settings are saved in EEPROM. Open-source software written for Arduino. Over-the-Air (OTA) mode allows updating the firmware remotely. Optional DS3231-based real-time clock (RTC) module (not included).
