How to Build an AI-based Air Quality Monitoring using ESP32 Air is a necessity for us human beings, so monitoring it is important. Air quality is monitored in terms of the Air Quality Index(AQI), a single-number scale used to tell how polluted the air is and what health effects it might cause. Particulate Matter is the microscopic solid or liquid which is present in air in the form of dust or smoke. Particulate Matter is the… |

A Simple DC-DC Boost Converter using 555 Timer IC In this project we build a boost converter circuit using a 555 timer IC. Boost converter is a non-isolated type of switch mode power supply that is used to step-up the voltage. In other words, it gives a higher output voltage compared to the input voltage. The circuit is very similar to a buck converter we designed for controlling motor and LED strip which is used… |

Buck Boost Regulator using XL6009 with Adjustable 3.3V to 12V Output Voltage Buck-Boost regulator is made using two different topologies, as the name suggests, it consists of both buck and boost topology. We already know that Buck Regulator Topology provides a lower magnitude of output voltage than the input voltage, while a Boost Regulator Topology provides a higher magnitude of output voltage than the provided input voltage. We have already built a… |

Variable Output Voltage DC to DC Boost Converter using MC34063 In the previous tutorials, we demonstrated detailed design of 3.7V to 5V Boost Converter using MC34063 and 12V to 5V Buck Converter using MC34063. Today we will use the same MC34063 IC to build a DC to DC Boost Converter circuit which can convert small voltage like 3v to higher voltage upto 40v. So here MC34063 IC is used a Adjustable DC-DC Converter. … |
