ATmega88 RGB lamp with DMX interface

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..

ATmega128 DMX Scanner

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..

PIC12F675 Digital Brightness Regulator

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..

Amplifier For RGB Led Strips

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..

MCP602 Sound card adapter

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,..

Dark Switch Circuit with 741 Opamp

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..

555 Led Dimmer Circuit IRFZ44

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..

2.1 Preamp Bass Filter Circuit 4558 Opamp

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..

Speaker Repair Coil Replacement

In general, the loudspeaker coil will light up as a result of overload or if the amplifier fails and supplies DC voltage to the output. Generally, repairs are not made..

JTAG AVR Programmer Isolator

The Jtag Isolator device is intended for designers working with devices supplied with voltage dangerous to life or at a potential much higher than the potential of the earth. In..
