In this part of the series we’ll cover the electronics. I’ll show you how I planned to build the internals of the clock and how I built it afterwards. Just like in the first part of the series I wrote this article while the build was in progress. I planned to leave errors I might make during this build in the articles, so that me and others can review them and don’t make the same mistakes again. If I find out that something is wrong, I’m going to mark it as wrong in the article and correct it afterwards:
In this article I have something stylish for you: It’s a project idea, I had for a while. And today I decided to finally build it! I’m pretty sure almost everyone of you has already seen a world clock, even if most of you have just seen them on pictures. For everyone else: It’s one of these clever clocks that do not display the exact time, but display a sentence, approximating the time instead, composed from different words that light up:
As these clocks can be pretty expensive, I decided to build some cheap ones myself. Three of them will be given to two friends of mine and one is for me. This article will be a description of the steps needed to create such a thing, so you can build your own one at home!
There are a lot of tutorials around that show you, how to etch your own PCBs, but either they use professional tools, that might cost a lot, or they do not give you a complete list of materials you will need. This really bothers me, so I want to show you how to produce your own PCBs at home, so you can make your DIY projects more professional and cut costs drastically when it comes to create a PCB.
