JK flip-flop

Check out my SR latch video first: https://youtu.be/KM0DdEaY5sY The JK flip-flop builds on the SR flip-flop by adding a "toggle" function when both inputs are 1. The S (set) and R (reset) inputs are now referred to as J (set) and K (reset) to indicate the

An effective solution to the "racing" problem described in my previous video (https://youtu.be/st3mUEub99E) is the master-slave JK flip-flop which comprises two SR latches. In this video I explain how it works, build, and test it. Support me on Patreon: h

Designing a 7-segment hex decoder

629 views / 0 likes - added 7 years ago

Building a combinational logic circuit to decode 8 bits and display a 3-digit decimal number on 7-segment displays is complex. In this video, I build something much simpler—a circuit that decodes 4 bits to a one-digit hexadecimal display—and even that's p

8-bit computer build: Connecting the bus

636 views / 0 likes - added 7 years ago

In this video, we'll first build a simple 8-bit register to store the contents of the computer's output. Then we put everything we've built so far together. Everything is tied together through the common bus and common clock signal. Support me on Patreon:

In this video, we'll use an EEPROM (28C16) to create a decimal display for an 8-bit value. The display uses multiplexing to drive four digits using a single EEPROM. As a bonus it supports both unsigned and signed (twos complement) display modes. Support m
