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 (5 … 27V) and an output current up to 20 A
For comfortable listening of audio phonograms, it is necessary to change
the timbre of the sound at different frequencies. This is related to acoustics,
room parameters, individual taste of a person, etc.
This equalizer is intended for this, which allows you to smoothly change
the frequency characteristic of the sound signal. Regulation is carried out by
five bands of double potentiometers R7-R11. An equalizer is connected
between the preamplifier and the power amplifier of the audio path. Two
LA3600 chips are used as active elements. The output of the equalizer
should be connected to an amplifier with a general volume control.
For high-quality and beautiful soldering, it is necessary to choose the right
power of the soldering iron to ensure a certain temperature of its tip.
This product will achieve excellent results at a low price.
The device can also be used to smoothly adjust the power consumption
of other devices with active load of which the power of which does not
exceed 200W such as heating element, incandescent lamp, etc.
The device is installed in a socket, and the switching load is connected by
a plug in a Digital Triac Power Regulator PMT-1A on the front panel of the
device. A distinctive feature of this regulator is a three -bit LED indicator
that displays the effective voltage selected by the user from 0 to 220V.
The power regulator is controlled using two buttons located on both sides
of the indicator. The left button reduces the current voltage by 5 volts, the
right increases it by 5 volts. To memorize the selected voltage value, you
need to briefly clamp both buttons at the same time. Changing power at
the load is carried out by switching it through the triac built into the device
This kit allows you to assemble a laboratory power supply with output current and voltage
regulation and short circuit protection.
The device has a maximum output voltage of approximately 100 volts – 30 V DC and 3 Amp, which is ideal for your radio laboratory. Using the additional regulator, you can set any output voltage value up to 30 V. The device effectively controls the output flow. This function ensures the ability to cut off strings during short circuits and over-the-air conditions. A visual LED indicator is provided as soon as the set value has been moved.
A device made up of 20 light-emitting diodes, arranged in the shape of a heart, can be used to decorate the family and store windows. The device will serve as a great beginner’s guide for teaching you and your child the basics of electronics. The simplicity of the scheme, the ease of folding and the clarity of the result make it easier to worry about. The result of the construction of this constructor is an effective light-emitting “heart” with the effect of a fire that can burn.
The light effect consists of two nested hearts made of 40 red LEDs that turn on alternately. The effect is dynamic, bright and very attractive. The device demonstrates the heartbeat of the human heart.
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.
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.
