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

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 !

I think you guys form INDIA…
Me too…
Me too did similar one in my college days Carry on GUYS..

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?
what are all the parts u used?? and how many
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.
Wow this is really interesting project. Congrats!
