Synthesizer, Guitar Effect Pedals Flanger etc. While various projects are generally circuits with Synthesizer signal generation, there are different projects. All projects have detailed descriptions of source assembly and hex codes. In translation, “Envelope generators” stands for Turkish as “envelope generator”. I’m not sure if the translation is not correct; Envelope generators are circuits that…
In order to test the electrical resistance of insulators, it is necessary to have a voltage source. The required output voltage depends on the type of materials tested. In this case, it is a source of adjustable output voltage in the range of 50V to 2kV sine wave with a frequency of 50Hz. The power…
The design of a light source with a DMX interface, consisting of RGB LEDs panel, and thus able to illuminate objects with light of almost any color. Over 60 super-bright LEDs with up to 100,000 mcd luminosity were used in its construction. The device fits the KM-95 enclosure, which has a handle for mounting it…
DMX interface. These were mainly receivers and transmitters, as well as devices enabling the development of DMX networks. When running prototypes or large installations, you will definitely need a DMX scanner that can provide invaluable services. Recommendations: the scanner will be useful to people dealing with technical equipment on stage, technical setting of events, etc.…
The controller allows convenient control of the intensity of lighting made of bulbs. It is not suitable for use with typical energy-saving fluorescent lamps and LEDs, unless they are adapted to work with typical dimmers. There are many similar solutions and probably every electronics engineer has performed a “dimmer” at least once, but this device…
Amplifier for RGB strips The dynamically developing field of LED lighting means that a whole range of devices related to such applications is needed. One of them is the amplifier described here, which allows you to increase the current efficiency of the controller. Scheme of the RGB LED strips amplifier is shown in Figure 1.…
Sound card adapter Multiple devices can be connected to the audio signal output of a computer sound card at the same time: a tower, a TV set, a speaker set, etc. Each of these devices loads the output to some extent and it may happen that the signal attenuation is too strong. This circuit is…
The circuit diagram you see in the picture works as a dark switch with the LDR on it. The circuit consists of four resistors, a 741 opamp, two potentiometers (optional trimpot available), an LDR, a switching TIP122 transistor and a lamp. In the circuit, the value of the resistor R1 is directly proportional to the…
The Led dimmer circuit you see in the diagram works like a DC dimmer, the brightness of a number of led groups can be increased or decreased. The supply of the circuit is + 12V and the led groups are grouped in series and parallel so as not to exceed the circuit supply. The circuit…
For the 2.1 amplifier project, I prepared a 4558 opamp preamplifier subwoofer filter circuit. The circuit is based on 2 4558 opamps, with the main audio input and bass output volume adjustment. Power supply symmetrical + -15VDC The PCB drawing was not very regular because I had to prepare it very urgently, but I ran…
