This module is a microphone with a built-in preamplifier, which has
a good amplitude-frequency characteristic and high sensitivity.
Such high characteristics are achieved due to the electret
(condenser) microphone used in the module.
Thanks to the built-in amplifier, the audio signal can be transmitted
via shielded wires up to 20 meters long. The module contains a
voltage stabilizer, so it can be powered from a non-stabilized
source with a voltage of 6…15 V.
The device is a variant of the C-MOY Pocket Amp portable headphone amplifier [1]. This amplifier is
necessary when using high-impedance headphones with reproducing equipment without a built-in amplifier
(mp3-players, PC audio card line-out), but can also be used with regular headphones.
Technical Specification Optical switch for cabinets etc. Turns on the lighting when the cabinet door is opened and turns it off when the cabinet door is closed. For closed structures such as for lighting cabinets, wardrobes, drawers. Power connection diagram (view from the connector side) (+) common positive from power source and LED (marked in…
designed for creating LED lamps using LED strips or rulers
and aluminum profiles. The sensor is mounted directly into the profile.
The principle of operation of the sensors is based on the reflection of the
infrared (IR) rays emitted by them from nearby objects at a distance of
up to 5 or 10 cm. Thus, waving a hand or opening and closing a cabinet
door triggers the sensor.
The kit is intended for the manufacture of power control. The device can be used to adjust the power of heating,
lighting devices, collector AC motors, the maximum current of which does not exceed 25 A.
Power regulators of the 216 series can be used in the regulation of lighting with
incandescent lamps, the temperature of heating the soldering iron, steplessly
controled, when controlling the heater, and the speed of rotation of electric
motors with a phase rotor.
Pulse metal detector – the module is designed for the manufacture of a metal detector that
allows to detect objects from ferrous and non-ferrous metals
€29.00Original price was: €29.00.€26.00Current price is: €26.00.
The module is a universal pulse metal detector on a microprocessor and uses
Clone PI-W circuit and software solutions. Designed to search for metal objects
in the soil, sand, walls, thick grass and others. The use of sensors of different
sizes allows you to solve a wide range of search tasks.
For comfortable listening to audio phonograms, it is necessary to change the sound timbre at certain frequencies.This is due to the acoustics, room parameters, individual taste of a person, etc. This equalizer is designed for this purpose, which allows you to smoothly change the frequency characteristic of the sound signal.Adjustment is carried out in five bands by dual potentiometers R7-R11.The equalizer is connected between the preamplifier and the power amplifier of the audio path.Two LA3600 microcircuits are used as active elements.The output of the equalizer should be connected to an amplifier with overall volume control.
The Hi-Fi class ULF is implemented on the TDA2030 integrated circuit. This IMS is a class AB ULF and is installed in audio devices to obtain a high-quality output musical signal of medium power. The device will be useful both for repairing existing industrial audio equipment and for building homemade amplifiers and subwoofers.

The voltage regulator module contains a rectifier and a stabilizer on a 7812 (101.1) or 7805 (101.2) IC
and is intended for use in simple devices that require a stabilized power supply of 12 or 5 Volts with a
current up to 1 Ampere.
In amateur radio practice, a power source is often needed, which has simplicity of execution, small dimensions
and high load capacity. This kit will allow you to assemble an adjustable voltage regulator with a wide range of
output voltage (3 … 27V) and an output current up to 10 A.
