Distortion and overdrive are types of audio signal enhancement that are employed to change the tone of amplified electric musical instruments like guitars. Typically, this is accomplished by increasing the gain of the instrument, which results in a “fuzzy,” “snarling,” or “grinding” tone. Depending on the type and degree of distortion used, the effects change […]

Using Electret Microphone on Computer PC
The small circuit that we propose here provides a 20 dB gain to the microphone signal, which will finally allow you to effectively use an electret microphone on your PC. Circuit Description The diagram of our circuit is reproduced in the Figure below. Don’t expect a complicated diagram with op-amps everywhere, as our circuit is […]
TV Antenna Amplifier Circuit Diagram to Boost TV Signal Reception
The following useful circuit of a TV antenna amplifier was sent to me by an avid reader of this blog Mr. Miljenko Farkas. I am extremely grateful to him for his kind contribution to this site. Here’s what he wrote in his email: Overview So this antenna amplifier is made to really enhance how well […]
What is ISD1820 Module? How to Connect and Use
The ISD1820 is a small ready-made module which can record human voice for short time and then play it back. It is based on the ISD1820 IC which is a voice record and playback chip. This module is very popular for DIY projects where we want to make some talking gadget or voice-alarm,or greeting system, […]
ISD1820 Voice Recording IC Datasheet, Circuit Diagram
The ISD1820 is a voice IC that lets us record voice from a mic and play it back using simple buttons or microcontroller. We can record between 8 to 20 seconds which depends on how we set it. This IC is used in small voice projects, talking toys, greeting circuits, voice alerts, and more. ISD1820 […]
10 Watt Stereo Amplifier Circuit Diagram
With a simple design, this 10 watt stereo amplifier circuit offers good dynamics and excellent bass reproduction. Although its power output is modest, at 2 x 10W RMS, it allows for comfortable use in small-sized rooms, such as apartments. When paired with speakers with a minimum power rating of 20W, it will provide complete satisfaction. […]
