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

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
With 5V 2A buck converter circuit using KA34063, can charge mobile phone with 10W solar cell that can supply current of 0.5A and 17V to 21V. 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
This is a DC to DC Buck converter working principle. We often use it as a step down DC to DC converter circuit. Because it is a switching mode power supply. Read more
