Homemade DIY word clock – Part 3.1

 

Introduction

This is the last revision I’m going to post before I completely finish the post. It has all the features I wanted and defined in the first part, and it’s as easy to manufacture and to build as possible. So this is just a really short and quick update with the newest files for editing and printing. Continue reading Homemade DIY word clock – Part 3.1

Homemade DIY word clock – Part 2.1 (Update)

An update on the project

It’s been a while since I posted something about the wordclock build. I want to apologise for that. I’ve been somewhat busy because of the university and I haven’t quite found the time to write about the project. Also it took me some tries to make the PCB at home. It took five tries until I was satisfied with the outcome.

Homemade DIY word clock – Part 2

Introduction

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:

mistake I made
correction

However in the last part we planned our clock in general. So now it’s on to planning the electronics that’ll give the clock a function. Continue reading Homemade DIY word clock – Part 2

Homemade DIY word clock – Part 1

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!
