Inverter Circuits Using 555, PIC, PWM, or MOSFET

December 29, 2022 by Charles Clark Leave a Comment

We all know what an inverter is and the importance of this device. It simply converts low DC power into high AC power. AC can’t be stored for future use, but you can store DC power in a battery for future use. The stored DC can be converted back to AC by using power inverters that can be used as the power source during a power outage. As this is a useful device for every … [Read more...] about Inverter Circuits Using 555, PIC, PWM, or MOSFET

Simple Continuity Tester Circuit Using 555 Timer

August 25, 2022 by Charles Clark Leave a Comment

Simple Continuity Tester Circuit

Normally we use continuity testing to check if a circuit, PCB, or cable is continuous or not. It also helps us to check if a bulb is burnt out or not. Simply we can do the test by using a battery and a led or buzzer. But they are not precise or accurate. Usually, we use a continuity test multimeter which is a bit costly and bulky too. Also, these give a … [Read more...] about Simple Continuity Tester Circuit Using 555 Timer

555 Touch Sensor

August 25, 2022 by Charles Clark Leave a Comment

555 Touch Sensor

How to make a touch sensor? Here is a simple DIY touch sensor circuit diagram using 555 timer monostable mode. The touch switch is only a conducting metal sheet that acts as a touch sensor. The 555 touch switch is not a touch capacitive sensor; it is only a metal touch sensor button. Using this you can turn on and off devices with a single touch. Here we are using a JK flip … [Read more...] about 555 Touch Sensor

How to Make a Simple Boost Converter with 555 Timer?

May 15, 2022 by Charles Clark Leave a Comment

Simple Boost Converter with 555 Timer

We may come across many circumstances where we need 12V from a 5V (as from USB ports which only provide 5V), but it may not be sufficient to drive all the circuits. To face such situations we are introducing a dc to dc boost converter circuit which can generate 12 volt from 5 volt. Today boost converter applications are used in different devices like dc dc … [Read more...] about How to Make a Simple Boost Converter with 555 Timer?

Regulated Dual Power Supply Circuit From Single Battery Source

May 1, 2022 by Charles Clark Leave a Comment

How to create a dual power supply unit using a single battery for your lab purpose? Dual voltage power supplies are required particularly for op-amp experiments and some of the instrumentation amplifiers. Some low-power audio preamplifiers also use a dual voltage supply. Here is a simple dual power supply schematic capable of producing +9V, 0V, and -9V (dual … [Read more...] about Regulated Dual Power Supply Circuit From Single Battery Source
