This article discusses the audio mixer design and operating principle based on the use of the LM741 operational amplifier (op-amp) IC. The features of the LM741 and the step-by-step creation of the audio mixer circuit are examined, while explaining how audio mixers work.

An electroencephalograph, or EEG, article describing the functioning of a medical device used to measure and record brain activity. EEG devices capture and analyze the electrical activity produced by the brain. They are widely used in fields such as epilepsy, neurological disorders, and sleep research.

The Brain Waves and EEG article allows us to understand brain activity by examining the electrical communication of brain cells. It contains detailed explanations of the functions of different brain waves and EEG technology.
