7400 competition entry: 7400 Logic Based Calculator

Posted on Tuesday, October 30th, 2012 in 7400 contest, contest by DP

7400 Logic Based Calculator is the open 7400 competition entry by students of the Pakistani Institute of Industrial Electronics Engineering. This was an assignment during their 6th semester course Digital Electronics II.

Digital logic based calculator built on 7400 series ICs which can add and subtract two digits with clear, and backspace as well

This project is made to perform calculations on 5-Bit signed data. Meanwhile we also need to implement logic to detect the type of input user pressed, and to perform operation as required. After all these things have been implemented we just need to display our data using 7-segment decoder to 7-segment display.

Build something that uses or abuses a logic chip and get amazing boards, tools, and other swag. The Open 7400 Logic Competition promotes awareness of the basic building blocks of modern circuits. Devious geeks ignited the computer revolution with discrete logic computers, what can you do? Details and entry form here.
