This bird sound generator circuit was one of the first circuits I built as a child. It is a fairly simple and small circuit made up of only a transistor and some common components like resistors, capacitors, an audio transformer, and a few others. The function of this circuit is straightforward: when pressing the switch, … Read more
Let’s make 3 LED chaser circuits using transistors without ICs. We will learn how transistors work as switches with capacitor discharge. Read more
We are going to learn how to design a small signal amplifier circuit using transistors in a simple way, with class A amplifier form. Read more
In the previous articles, we learned about using a transistor as a switch, that was, either completely on or off. But circuits such as the audio amplifiers will require the transistor to be partially on, which is very interesting. But it can be quite a difficult subject for beginners who just started learning electronics to … Read more
Let’s experiment 5V buck converter circuit using transistor in the series voltage regulator. It worked but not be switching mode why? Read more
