YT-81302 is a universal travel adapter with a built-in charger featuring two USB ports, supporting electrical standards in over 150 countries. It includes retractable plugs with a locking mechanism and short-circuit protection via easily accessible ceramic fuses. The housing is made of durable, flame-retardant plastic, ensuring safety and reliability during use.

This small synchronous switching step-down (or buck) regulator takes an input voltage of up to 38 V and efficiently reduces it to 9 V. The board measures only 0.7″ × 0.7″, but it allows a typical continuous output current of up to 2.5 A. Typical efficiencies of 85% to 95% make this regulator well suited for powering moderate loads like sensors or small motors.

The Rebel Tools 5 m × 19 mm tape measure, made of lacquered steel and equipped with a precise locking and rewinding mechanism, is a practical measuring tool for home, workshop, and construction use. Thanks to its sturdy housing and functional design features, it allows for quick and accurate measurements in various working conditions.

The Pololu A-Star 32U4 Prime is a general-purpose programmable board based on Atmel’s ATmega32U4 AVR microcontroller and arranged in the common Arduino form factor exemplified by the Uno R3 and Leonardo. Pololu 3114

Hybrid bipolar stepping motor with integrated 38cm (15″) threaded rod as its output shaft, turning it into a linear actuator capable of precision open-loop positioning. The motor has a 1.8° step angle (200 steps/revolution) and each phase draws 1.7A at 2.8V, allowing for a holding torque of 3.7kg-cm (51 oz-in). Pololu 2690

The 2xRCA "J" 5m cable is a 5-meter-long stereo audio cable with two RCA plugs (red and white) on each end. It is used for transmitting analog audio signals between audio devices such as amplifiers, players, or televisions.

The 25-meter RG6U CCS coaxial cable features a 1 mm copper-coated steel core and a shield composed of 48 aluminum wires and aluminum foil, providing effective protection against electromagnetic interference. With a 75 Ω impedance and an outer diameter of 6.8 mm, it is ideal for television and satellite installations.

The compact (0.4″ × 0.5″) D24V5F9 synchronous buck voltage regulator takes an input voltage of up to 36 V and efficiently reduces it to 9 V while allowing for a maximum output current of 500 mA. Pololu 2845
