AC Ammeter Circuit for Measuring Current across 220 V Appliances

Last Updated on June 8, 2026 by Swagatam 8 Comments

AC ammeter circuit

In this article I have explained how to build a simple AC ammeter circuit which can be used for checking the current consumption of household 220 V or 120 V appliances. The main reason for high monthly utility bills is the use of large electrical equipment like refrigerators, washers and dryers, dishwashers, etc. These appliances […]

How to Make 1 A Constant Current LED Driver Circuit

Last Updated on June 1, 2026 by Swagatam 16 Comments

1amp led driver IC specs

In this article I have explained a simple 1 amp constant current LED driver circuit using the IC MBI6651 from MACROBLOCK. The IC has been specifically designed for operating high power LEDs safely by providing a constant current output. The circuit includes very few external components and therefore becomes very easy to assemble at home. […]
