Here is the transistor graphic equalizer circuit. Why should make this circuit? We use it for controlling the audio frequency in some kinds of audio frequency responses that are not flat. Which we cannot use a normal tone control circuit. Because it has a too wide bandwidth. We need to use a good equalizer circuit … Read more
Do you like a transistor? Today I am going to 3 transistors audio amplifier circuits. Why use transistors in the amplifier? Transistors are devices made of semiconductors. It has many benefits, but the most important and common use is to use it as an amplifier. How? Must … follow to see. Although currently, we will … Read more

Imagine your dad is old. Sure, he hears anything weak sound.
How do you do?
You are an electronics inventor, right?
Yes, you can try to make a tool. To help him back to listen to great music again.
This project is small, use only one 1.5V battery. Using normally components you can buy in stores near you. Read more
