Designing small signal amplifier circuit using transistor simply
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
Experiment with adjustable transistor circuits partially on-off
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
0-12V 3A Variable Power Supply using LM350
In a normal circuit, the general LM350 regulator has a start voltage of 1.25V. But this circuit is special that start of 0-volts. We use only one IC and a few other components. So cheap and easy for you. Read more
Simple Water Level Alarm Circuit using a Transistor
It worked by sounding an alarm when the water level rose to the set level. So we can close the water valve in time and prevent an overflow. Read more
DIY Flashing Bicycle LED Taillight Circuit
Today we will be learning electronics through creating a simple circuit again. This time, it is the flashing bicycle LED taillight circuit. That will emit a flashing red light on the back of our bicycle to increase safety at night. We have designed this circuit with basic electronic principles in mind, so there would not … Read more
