Build this Simple Solar Egg Incubator Circuit
In this post I am showing you one very nice and simple solar powered egg incubator circuit project. Many people ask me bro how to upgrade simple incubator with solar charger and battery backup so egg will not spoil when main power line is going off. In rural areas power cut is major problem for […]
High Frequency PWM Electric Arc Metal Engraver Circuit
Today I am showing you how to make very powerful pen style electric arc metal engraver circuit using IC 555 and MOSFET. Actually this idea is inspired by one of my blog reader, and my friend Mr. August. He made one crude engraver using 6V transformer and tractor charging coil, but he wanted a smooth […]
100V to 450V Solar Battery Charger Circuit with Automatic cut-off using MOSFET
Hello friends, today we will discuss about a very interesting high voltage solar panel battery charger circuit. Many people ask how to safely charge battery from high voltage PV panels like 100V to 450V. So today I am explaining the complete step by step working of this circuit. Power On and Initial SCR Latching Assuming […]
Build this Simple Zener-Stabilized Wien Bridge Sine Wave Generator Circuit
This zener diode stabilized Wien Bridge sine wave oscillator circuit is very easy to build and test, let me explain full working in simple way. Basically here we are using TL072 opamp which needs dual supply like +15V on pin 8 and -15V on pin 4. Pin 1 is our main output pin from where […]
SMPS LED Bulb Circuit with Dimmer Control using IC IRS2530D
Today we are going to look into a very high efficiency resonant-mode off-line LED driver circuit. It is based on a very popular Infineon article which uses the IRS2530D DIM8 controller IC. Normally electronic ballast technology is used for old fluorescent tube lights, but here Infineon used the same concept to drive high power LEDs […]
