In digital systems, I teach about a bunch of different hardware solutions that can be used to implement a project. I thought it would be fun (and not to mention, a learning experience for me) to come up with both a combinational logic project and a sequential logic project and implement each one using a …
The purpose of this post is to make the design process of creating printed circuit boards (PCBs) a little less scary. Please note that, as with most of the hobby stuff on my website, I am self taught. This means that I use auto-routing, don’t worry about ground planes, and the most difficult thing I …
Frequently, I will come up with an idea for a project I’d like to do. Some of the projects are small in scope, like designing a PCB for some DIP components so that my students don’t have to spend time wiring up a frequently-used component (like the 7447 and a 7-segment display). Those are relatively …
It can be very difficult to convey to students sometimes just how much effort can go into diagnosing a circuit that isn’t working, and how much tenacity it takes. There are many resources that can be used to try to overcome problems. I figured it might be a good idea to write about my experiences …
