In this post I have explained a simple IC 555 set/reset application circuit for activating or deactivating a relay alternately. Audio/Video Representation Circuit Operation This electronic set reset circuit is very simple, easy to implement and very useful. It can provide you many applications options in cases where it may be necessary to toggle (switch […]

How To Use And Program ATmega Microcontrollers From Scratch Without Arduino
ATmega microcontrollers, they are coming from the AVR family which Atmel developed long back, and later this Atmel company was taken by Microchip. So now officially Microchip owns it but still people say Atmel AVR only. These MCUs became very popular slowly because they are easy to understand, quite affordable, stable in long run and […]
Make this Single MOSFET Solid-State Relay SSR circuit
This single MOSFET solid-state relay SSR circuit is a very simple where you can drive an AC load like a lamp, motor, or any oter AC load, through a small DC control voltage. We use only one IRF840 MOSFET to switch the 220V AC load, and we do this with some clever diode bridge arrangement, […]
Calculator to Design a High Power 3kW PFC (Power Factor Correction) Circuit
In this post I will explain how to use this active PFC calculator for calculating high current, high PFC designs. In our example we will be using 230 VAC input and 3 kW output and Vout equal to around 390 V, and we will try to see how each resistor and capacitor gets calculated in […]
Blood Electrification Circuit: Explanation And Working Principle
Here we are talking about one circuit which many people know by the name Blood Electrification Unit, and this circuit became known because of Bob Beck many years back in the 1990s time, so now people also call it Beck Blood Electrifier. This unit is nothing complicated looking but the idea sounds heavy because it […]
EV Wireless Battery Charger Calculator Tool
This calculator helps estimate resonant frequency or compensation capacitor for a wireless EV charging primary coil. It is for first-step design and learning, not final tuning… Calculator by homemade-circuits.com EV Wireless LC Resonance Calculator EV Wireless LC Resonance Calculator Calculate: Resonant Frequency (Hz)Capacitance (µF)Inductance (µH) First Value: Primary Inductance µHCapacitance µFFrequency Hz Second Value: Primary […]
