The Kit

DIY kit for making a mini radar with ultrasonic obstacle detection, based on UNO R3 compatible board. Includes HC-SR04 sensor and SG90 servo motor for scanning, 1.8 inch color TFT display with real-time graphics, easy integration into Arduino IDE, ideal for educational projects and distance measurement experiments.

Demonstration device for visualizing the movement of charged particles and circular acceleration, with a circular track on a durable acrylic base and 4 electromagnetic coils controlled by 4 inductive sensors that propel the balls along the path. LEDs on the coils confirm each detection, the compact construction offers an intuitive presentation, ideal for laboratories and classroom demonstrations.

2WD aluminum chassis, sturdy and lightweight, ideal for educational and hobby robotics projects. Includes two 6V DC geared motors, two good grip wheels and a swivel wheel for stability, turning is done by speed difference for precise control. The perforated frame allows for quick mounting of sensors and boards, compatible with Arduino and double H-bridge.

Set of female pin headers for rapid prototyping and secure connections on PCBs and breadboards, 2.54mm pitch, 120 pieces in 8 common lengths for maximum flexibility, delivered in a transparent box with compartments for organization and quick access, ideal for electronic projects, repairs and module testing.

Complete 16-piece kit for maintenance, diagnostics and repairs of electronics and phones, includes VC830L multimeter for precise measurements and 30W letcon for fine soldering. It has flux pump and 0.6 mm flux roller for quick corrections, plus wire strippers, screwdrivers, tweezers and plastic levers for safe interventions.

Compact solution for air purification and water sterilization, delivers up to 0.5 g/h adjustable ozone at only 9 W. Uses corona discharge for efficient conversion and low noise, quartz glass tube with 316L stainless steel electrode for stability and chemical resistance. Works with air or oxygen and has a lifespan of over 20,000 hours.
