If you’re going to learn digital logic, why not aim high? That’s what [Easton] and his friend did when they built a clock using only 4000-series logic chips. On a breadboard, no less. For a 1 Hz clock ...

Electrical and electronic circuits are around us. From our mobile phones to security systems, electronic circuits are everywhere. Designing a circuit follows a step-by-step procedure. Most of the time ...

It is hard to imagine experimenting with electronics without the ubiquitous solderless breadboard. We are sure you have a few within arm’s reach. The little plastic wonders make it easy to throw ...

Even in today’s digital, IT-intensive radio plant, there is still a need to design and build one-of-a-kind electronic circuits. Simple devices such as digital tone generators and small distribution ...

As I mentioned in my recent columns on the topic of adding pull-up or pull-down resistors to the inputs of unused or partially used logic gates and functions (see Part 1, Part 2, and Part 3), I was ...

If you watch our Youtube channel you probably know that I use a breadboard to test different circuits. I find this method very simple and easy to use when you need to test a project before making the ...

What in the world is a breadboard? That’s an excellent question and I’m glad you asked. To thoroughly answer this question we need to take a quick trip back in time to before the 1960’s. Back then if ...
