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.

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.

This is a DIY soldering kit. 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.
