In this post I have explained a simple and effective industrial timer circuit which can be universally used for most industrial and home timer based applications. The idea was requested by Mr. Vasilis K. Technical Specifications I have a question regarding the 4060 ic wired as “one shot timer.” If it can power on the […]

3 Solid-State Single IC 220V Adjustable Power Supply Circuits
These AC to DC power supplies use a single chip to convert mains 220 V or 120 V input AC into 12 V or 5 V DC without depending on a transformer. Three simple yet efficient 220V single chip based solid state transformerless adjustable solid-state power supply circuits are discussed here. The first one works […]
Adjustable 3V, 5V, 6V, 9V,12V,15V Dual Power Supply Circuit
The purpose of this paper is to detail a variable dual lab power supply circuit which has an adjustable range from 3V, 5V, 6V, 9V, 12V, and 15V or even more at an output current rate of 1 amp. Written By: Dhrubajyoti Biswas The Dual Power Supply Concept In regard to positive volt it is […]
Adjustable Drill Machine Speed Controller Circuit
The proposed variable drill speed controller circuit maintains a constant (adjustable) speed over the drill machine motor, regardless of the load. One of the most used power tools is the power drill machine. Despite its innumerable advantages, the power drill has one major setback – constant high speed for many applications. Even when there are […]
0 to 50 V Adjustable Switching Power Supply Circuit using IC LM2576
In this article I will try to explain the construction of a 1.23 V to 50 V adjustable switching power supply circuit using the IC LM2576. The LM2576 family of regulators is a monolithic integrated circuit that performs all of the active operations of a step-down (buck) switching regulator. It offers exceptional line and load […]
FM Signal Booster Circuit with Adjustable Gain
Did you’ve ever had trouble catching or establishing connection with distant FM radio stations which were broadcasting programmes you wanted to listen to? Perhaps you’re aware there are a lot more faraway channels, further than the range of your FM receiver. Of course, you could purchase or construct a stronger FM tuner but, building a tunable FM […]
