Many electronic devices operate in conditions where the fan rotates at idle, and create a constant, annoying
noise, accelerating the wear of the fans. The function of this thermocontroller is to reduce the noise from the
constantly-running fans by stopping them until the temperature exceeds a predetermined threshold. The module
can be used in computer system units, in power units, and any other electronic devices that use cooling with
fans. The proposed thermal controller works with 12V or 24V fans, in the start-stop mode, with a hysteresis of
2-5 ° C.
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
The M158.3 metal detector is a device similar to hand-held metal detectors used by guards to search for metal
objects in people’s clothing. The device is able to find metal objects from ferrous and non-ferrous metal at a
short distance. Using this metal detector, you can detect keys, a mobile phone that are under clothing, a metal
profile under drywall. For gaming purposes, children can look for coins hidden under a carpet or in the sand.
Included is a soldered module and a compartment for two AAA finger batteries with a switch. Batteries are not
included. You only need to solder the two wires to the metal detector board and, if desired, fix the battery
compartment to the board with double-sided tape
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.
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.

The device can be used to indicate the tuning of the tuner, the signal level at the linear output, the indication of
the output power, etc. The designer is a line of 9 LEDs with a logarithmic scale.

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.
