In this post I have explained how to make a simple IC 555 based alternate relay timer circuit for toggling a couple of loads alternately with a specified length of delay, as determined by the calculated values of the relevant components. The idea was requested by Mr. Sanjoy. Circuit Objectives and Requirements The Design Referring […]
Newly Updated Circuit Projects:
LED Strobe Light Circuit with Chasing, Flashing Effects
The proposed LED strobe light circuit will not only flash a group of LEDs with strobe pulses, but will also create a sequentially chasing effect over the strobing LEDs. You might be quite familiar with colorful LED strobe lights, and should have seen them pretty commonly in parties and discotheques. Let’s see how we can […]
Make this IR Remote Control Range Extender Circuit
In this post I have explained how to increase or extend the range of an ordinary infra red or IR remote control through a 433MHz RF remote control system. IR Range Extender Concept The idea of this circuit is to feed the IR data from an IR transmitter into the transmitter input of an RF […]
Simple TV Transmitter Circuit (Audio and Video Combined)
The TV transmitter circuit presented in this post incorporates the European standard FM frequency for audio and Video up-links. Referring to the circuit below, Q1 is configured as a preamplifier for amplifying the audio input to be modulated. Circuit Description Q2 is fundamentally responsible for conducting a couple of important functions: It amplifies the carrier frequency […]
20 Watt Fluorescent Tube Light Circuit with 12V Battery Operation
This simple 20 watt home tube light circuit will work with any 12V battery and uses very few components yet is able to produce a reasonable amount of white light. The components used are very common and can be easily procured from the local electronic retailer. The idea is simple, the secondary winding of Tr1 […]
Stepper Motor Driver Circuit using IC 555
In this project we are going learn how to make a simple unipolar stepper motor driver circuit using 555 timer IC. Apart from 555 timer we also need IC CD 4017 which is a decade counter IC. By Ankit Negi Any unipolar motor can be connected to this circuit for performing specific task, though you […]
