4 Simple Transformerless Power Supply Circuits Explained
In this post I have explained 4 easy to build, compact simple transformerless power supply circuits. All the circuits presented here are built using capacitive reactance theory for stepping down the input AC mains voltage. All the designs presented here work independently without any transformer, or no transformer. The Transformerless Power Supply Concept As the […]
Transformerless Current-Controlled LED Bulb Circuits you can Build at Home
In this post I have elaborately explained how to build simple transformerless LED bulb circuits using many LEDs in series and powering them through current controlled capacitive power supply circuit. Warning: Circuits I have explained below are not isolated from mains AC, and therefore are extremely dangerous to touch in the powered and open condition. […]
Pseudo-sinusoidal IC 4047 Inverter Circuit
From a continuous source, battery, or vehicle alternator, it is possible to produce a 50 Hz voltage/pseudo-sinusoidal waveform, using this simple IC 4047 inverter circuit. The design is capable of operating many low-power devices that require a voltage of 220 V AC, typically supplied by the AC mains grid distribution network. The power of this […]
Quadcopter Remote Control Circuit without MCU
Although a quadcopter remote control circuits can be very easily procured from the market or from any online store, an avid electronic hobbyist is never allowed to learn how actually these function and whether or not these can be built at home? In this article I have explained how to build a simple quadcopter remote […]
5 Simple Electronic Dice Circuits Explained [Digital Dice]
We all know what a dice is and how manually a dice is shuffled and thrown to get a random number. In older times when we did not have computer games or mobile games, we used to play with various indoor games that required tossing a cubical thing called dice having 1 to 6 dots […]
