There are many different ways in which we could implement our 4-Bit Chewy Computer — here are a few possibilities for you to peruse and ponder In my previous column on this topic — “Building a 4-Bit ...

Would you consider this to be doing math the old-fashioned way? Instead of going with silicon-based switching (ie: transistors) this 4-bit adder uses mechanical relays. We like it for its mess of ...

Anyone reading this uses computers, and a few very cool people have built their own computer out of chips, [zaphod] is doing something even cooler over on hackaday.io: he’s building a computer from ...

Designed a 4-bit counter using a J-K flip-flop that has a clocked input with reset. Performed simulations of various output parameters like rise time and fall time. The design is done using cadence ...
