One of the current projects I’m tinkering with is an 8-bit computer. It’s something I’ve wanted to build for several years, and now that I’ve finished so many other projects, I finally have the bandwidth to take this on. I’m aware that Ben Eater has done this, and I’m not intending to compete with his …
Any synchronous sequential digital logic circuit requires a clock source (a square wave oscillating between logic LOW and HIGH values) for the circuit to function. Typically, a clock frequency is determined by the circuit designer (taking into account speed requirements as well as any limitations from the circuit components themselves). Once that frequency is known, …
Apparently, people actually read this blog (who knew!), so why not write about a topic I find interesting: multiplication. Multiplying two values together (as opposed to multiplying one value with a constant) is actually a difficult computational task. This was difficult to do in mechanical analog computers (shout out to any potential future mechanical engineers …
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 …
