A kit of parts to build a 2-stage pre-amplifier with a wide frequency range. Ideal as a pre-amplifier for power amplifiers or as headphone amplifier.

This module consists of an LED soldered to a constant current circuit. It can be connected to any voltage between 4 and 30V DC. The LED shines with almost constant brightness regardless of voltage ...

A handy selection of 50 electrolytic capacitors.

The Kemo P5123 Miniature Piezo Tweeter Speaker has an aluminium spherical cap for especially low distortion and constant high pitch radiation. It is highly suitable for ultrasonic vermin scarers du...

This Kemo preamplifier module is suitable for microphones and other general-purpose audio uses. The compact-sized module is simply connected between a weak signal source and the power amplifier.

This solder-yourself kit switches a relay on or off at a preset temperature. It is ideal for use as a thermostat, frost alarm, fire detector, etc.

This module monitors the charge status of a 12V lead-acid car battery and recharges it automatically when the voltage falls. When the battery is full, the module shuts off the charging process and ...

A kit of components including a printed circuit board to construct a highly sensitive microphone amplifier.

If the 2 sensor connections of the module come into contact with water, the built-in relay switches on. Sirens, other cutoff relays, etc. may be triggered with that.

A kit of parts to build a 'Wheel of fortune' style, random selector, ideal for electronic games, quizzes, etc.After releasing the pushbutton, all of the LEDs light except for one, creating a gap th...

This adjustable DC to DC converter module is ideal for operating devices that use a lower voltage than that available from a battery or fixed voltage power supply unit. The output of the converter ...

A sturdy 18W amplifier module for general-purpose use as a speaker power amplifier. The module is cast, moisture-proof and vibration-proof. The casting mass and module housing are made of a special...

This electronic light-operated switch automatically turns on lights or other appliances when darkness falls and switches them off again at daybreak. The module can also work in reverse, i.e., on at...

This solar charging controller module can be connected between a 12V DC solar cell (open circuit voltage 14 to 30V DC) and a 12V DC battery to prevent overcharging of the battery.
