In this article I want to cover an alternative I’ve come across while building the “real” word clock project. This version will not feature a 12×12 LED-Matrix display. Instead it’s made with LED strips and only the significant words on the clock can light up. With this method you can’t display custom messages, but the whole build won’t cost you as much either. Read all about this build in this article or watch this video:
In this part, I’ll design the 4-phase-clock of the CPU and I’ll make all the missing connections between the components.Continue reading How to design your own CPU from scratch – Part 4
In this part of the series, I’ll introduce the necessary components needed for storing and executing programs on our micro processor! I’ll try to keep this part quite short, because I already explained what a micro-instruction is and what it consists of on this CPU in part 2!Continue reading How to design your own CPU from scratch – Part 3
In the first part of this series, I discussed the ALU of our CPU. In this part, we’ll take a look at the data and program storage and how to address the them. I’ll also discuss how the ALU is controlled.Continue reading How to design your own CPU from scratch – Part 2
This series will discuss the basic building blocks of a simple theoretical CPU design. In it, I’ll cover one topic in each article and append the theoretical design. In the end, we’ll have a functioning CPU model.Continue reading How to design your own CPU from scratch – Part 1

Just a real quick update about the project.
I have taken apart several old computers this weekend and so I had several old PSU laying around afterwards. I opened one up that was known to be faulty, that’s why I got the computer for free. So I took a quick look inside and several caps were leaking. I decided not to throw it away, instead I repaired the PSU and gave the internals a new life. I actually had this idea years ago but I didn’t have a spare PSU I could take apart. Here is a rough guide on how to build your own power supply for almost no cost at all!
