In this post we will discuss two methods of designing pure sine wave inverter circuits using 555 IC based SPWM processing. In the first concept we connect the 555 processors directly with the SG3525 outputs and do the sine wave conversion directly at the MOSFET gates. In the second concept we do it externally and […]
Newly Updated Circuit Projects:
Arduino Digital Clock Using RTC Module
In this post I will show how to construct a digital clock using RTC or Real Time Clock module. We will understand what “RTC” module is, how to interface with Arduino and what it does. RTC module is a circuit, which keeps track of current time accurately. It does two functions, it communicates with microcontrollers […]
Beacon Level Indicator Circuit for Combine Harvester Grain Tanks
In this post I have explained a beacon indicator circuit for combine harvester grain tanks. The idea was requested by Mr. John Bosch. Circuit Objectives and Requirements I would like to retrofit the rotating beacon grain tank level indicator system shown below, to my older combine harvester. The particular part of the system I want […]
Corona Effect Generator Circuit
In this post we study regarding what is corona effect and how to make a corona effect generator circuit at home using a CDI coil and a tesla coil configuration. Then idea was suggested by Mr. Sanjoy Corona Treatment for Paper Coating Many many thanks for posting the alternate switching timer circuit as requested. Although […]
Make this 7 Segment Digital Clock with Beep Alert Circuit
In this post I will show how to construct a digital clock using 7 segment LED display with Arduino controlled design. How the Circuits Works The proposed 7 segment clock circuit is inexpensive and even beginner in Arduino can accomplish it with ease. This clock consists of four 7 segment displays, two for hours and […]
Battery Full Charge Indicator Circuit using Two Transistors
This little circuit will alert the user regarding a battery reaching its full-charge level (over charge) while it’s being charged, by illuminating an LED. The circuit uses just a couple of transistors as the main active components. Main Feature The main feature of this design is not only its mini design but also its supply […]
