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!

Quick look at: A cheap DIY function generator kit

Introduction

I recently bought some cheap electronic DIY kits from amazon, just because I wanted to improve my soldering skills. One of them was a cheap function generator based on the XR2206-IC. The complete kit with an enclosure costs about 14€ and it can be bought here. If you find a cheaper one let me know in the comments below and I’ll update the article!

JXD S7800b android gaming tablet test

Today I want to write about a rather unusual device that was around for a pretty long time actually, but that I have never heard of before. I also did never encounter this device in the ‘real life’ server of this game. However, recently someone sent me a link to this device and I found it quite interesting. I’ve seen devices like the S7800b some years ago, but I think the concept of a tablet with built-in hardware controls just did not get very popular. I mean why should it? The buttons seem to distract you anyways when performing typical tablet activities like browsing the web or watching movies. And usually android games tend to be made for touch only devices, so is the JXD S7800b any good at all? Let’s find out!
