Tic_Tac_toe

First of all thanks to DangerousPrototypes! its because of you guys I worked on logic gates after college – else its usually the usual microelectronic stuff! :)

This build is a simple ‘Tic Tac Toe’ game. I ended up using 30 Logic ICs ! :)

Lets see the video first, then lets see the design

<PDF alert> This document: Tic_Tac_Toe has all the block diagrams and circuit diagram used.

Do leave a comment if you have any queries!

PS:  The casing is ugly 😛 Trying to build a good case for this project!

<Edit> Won a first place in the 7400 contest !

    Can I ask where the reset button is connected? Is it connected to the power? And how much power did you supply the circuit? 5V? 9V?

    Hi
    It is wonderful. I want to show the logic o my students of the course i offer “Digital Electronics and Microprocessors” so i request You to share the design document.
    Once again I am happy that you have taken so much interest in digital electronics.
    Best wishes
    Prof. C R Sarma

    I wonder if you know where I might obtain the boolean expression for this circuit? I am trying to explain boolean logic and have used this as a physical example of interpreting a boolean expression as physical gates but I don’t have the expression for your game. Any help appreciated but I understand if you do not have the time. Many thanks.
