    Electronic Code Lock using Single Transistor

    Posted Nov 16, 2014 By Sudheer Gupta
    This article describes one transistor code lock circuit which is a key coded door lock system. Here interesting thing about this circuit is that it can be done without any programming. This circuit is simple and made up of simple transistor and buttons. Circuit Principle The main principle of this circuit is that the door lock opens only when the buttons in series are pressed at a time. If…

    Police Lights Using 555 Timer

    Posted Nov 09, 2014 By Sudheer Gupta
    This circuit simulates the police car lights by alternate flashing. This circuit flashes red LEDs for three times and blue LED’s for three times. This flashing action performs continuously. This circuit uses 555 timer and a decade counter. Here, 555 timer runs in astable mode. Decade counter 4017 counts the incoming pulses that is for first pulse Q0 becomes high and for second pulse Q1 becomes…

    miniRobot

    Posted Nov 02, 2014 By Yuri Tikhonov
    Introduction Not so long ago I was participating in AXP Logic Design Contest and took an honorable place there. I created an ultra-miniature robot that I called “nanoRobot”. On the prototyping stage I had to significantly increase the robot’s size. After that I created a new power system, control system and sensors system. As you understand it was an absolutely different robot. I…

    LPG Pumping Machine Controller

    Posted Oct 12, 2014 By Deepak Gupta
    The requirement of the project was to implement a small PCB that can be attached on to the motor itself. Hence we used the PIC12 microcontroller that has a very small foot print as well as a very low cost. The current sense input determines the load that that motor is experiencing and hence based on the load of the motor and also a internal timer the pumping was to be cut off.
