Make this 2 Pin Bi-Color LED Flasher Circuit
This transformerless mains power supply circuit will allow flashing of a Bi-color 100 LED string, in an alternately switching red, green effect. Using 2-pin Bi-color LEDs The proposed circuit can be used as a Bi-color LED flasher, for generating an alternate red, green flashing effect over a string of 100 LEDs. Bi-color LEDs are available […]
Toy Motor Circuit with Timed Reverse Forward Action
In this post I have explained a simple programmed reverse forward motor circuit which is used for accomplishing a toy application. The idea was requested by Mr. Matthew. Technical Specifications I am a new follower of your website which is a great resource! I need your help designing a circuit please. My daughter has a […]
Make this LED Cricket Stump Circuit at home
In this post I have explained how to make an illuminated LED cricket stump and bails for helping umpires declare a foolproof OUT, NOT-OUT decisions. The Circuit Concept You might be seeing these amazing cricket stumps in the ongoing 2015 ICC world cup cricket matches, which can be seen dazzle or light up brightly as […]
How to Build a 220V DC Inverter UPS Circuit
In this post I have explained a simple 220 V to 220V DC online UPS inverter circuit. The idea was requested by Mr. Taiye. Technical Specifications I intend to build a 1000 watt UPS with a different concept (inverter with high voltage input dc). I will use a battery bank of 18 to 20 sealed […]
Transformerless Constant Current LED Driver Circuit
In this post I have explained how just a single IC MBI6001 can be used as a transformerless constant current LED driver circuit for illuminating a chain of many LED in series. The MBI6001 series of ICs are designed to work with mains AC inputs and convert it into a lower voltage DC output which […]
