Long-time readers of this website might recognize this article. It was the first article, I published on nerdhut. As of today, this is still one of the most popular articles on the page and because of that, I decided to shorten it a bit and translate it to English.
However, the original German version remains online here!
Due to my work on a remote-controlled unmanned ground vehicle, I searched for a way to control it anywhere in the world. Because I wanted it to have a high range and reliability, I decided to communicate with it over the internet, which should be available almost anywhere on the planet.

I’m currently working at a custom messaging system, which will users to exchange encrypted messages. To achieve this, I bought a ENC28J60 powered ethernet module, which can be used to connect an Arduino to the Internet (or any other microcontroller that supports SPI). In this short article I want to show you how to connect this module and get it up and running in no time! Continue reading How to connect your Arduino to the Internet with the ENC28J60
You might remember that one article I wrote about Lambda expressions in Java last year. In that article I took a quick look at what Lambda expressions are and how you can use them in Java. This article was quite popular and I thought it’s about time that I write something about regular expressions here on nerdhut. However I only wanted to give you an introduction about regular expressions and how you can use them in your Java code to detect patterns in a text or to search for something.

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:

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!

Some time ago I wrote an article about how to get started with Windows 10 App development. This article will introduce you to Mac-Apps and will guide you through the process of programming one with Xamarin and C#.
Easy to follow video included at the end of the article.
