How to use enc28j60 ethernet shield with Arduino Mega 2560

Today it is time to talk again about one of my favourite gadgets – my Arduinos. In particular, for the Arduino Mega 2560 and how these can be used in combination with the enc28j60 ethernet adapters.
No products found.The enc28j60 Ethernet adapter should be known to one or the other of you, who has ever tinkered with an Arduino. These are the low-cost ethernet shields, which are available for example at eBay for less then 5$. Sure, the wiring and the library (the original ethernet library isn’t compatible), are not quite as comfortable as those of the original ethernet shields, but you can also save 30$ and more compared to the official ethernet shield.
For the Arduino Uno, there is already a handful of useful articles, which refers to the enc28j60 and Ethercard library. However, for the Arduino Mega 2560, I could not find anything useful information, so I would like to […]

Since Apple’s Siri voice recognition/voice control has again got back in focus of the crowd. But Siri is far from being the only working voice control solution. There were already a number implementations before, some good some bad, and there is still far more than just Siri.
How you can “install” a voice recognition into your website with just one line of code, is what I want to show you today. The whole thing is based on HTML5 and is established as an input element-tag.
And this is how it works:

Who wants to see the speech recognition in action, should go over there. The only downside of this solution is the fact, that this speech recognition is far from cross-browser compatible. So at the moment it’s only implemented in Google’s Chrome browser. However, I could […]

Mastering OpenSSH – Part 3: How to secure login by using a key file

After we set up an OpenSSH server in the first part and completed the basic configuration to secure the server in the second part of this article series, we now want to configure the server to make use of a key file (hereinafter also “key”) for the login process.
The SSH key authentication is based on the principle of asymmetric encryption. So we need a key pair consisting of a public key and private key. The public key is then stored on the OpenSSH server and the private key goes to the client.
The top priority here is to keep the private key secret forever and in any case. If someone else comes into the possession of the private key, he or she can log on to your server.
As a small obstacle you can provide the private key itself with a password. But nevertheless, if the private key gets public or falls […]

Today I want to present you a WordPress plugin once again. But let us start with a short introduction.
Google’s autocomplete feature called Google Suggest should be known by everyone who uses Google. (And that should probably be the most.) It is really convenient if you do not have to type in the complete search phrase everytime, because Google already suggests, what you actually wanted to write/search.
However, Google Suggest offers even more. Because if you do not know which keywords you need to use exactly, or want to know what is popular, so you just type a few letters or a word and then Google is proposing all suitable or relevant search phrases. And here we come to the WordPress plugin, that I want to introduce you today.
Uwe Ramminger from seo4wp.de namely has developed a small WordPress plugin called […]

Are you one of those people who used to (or still do) spend hours, sitting in front of a game console? I for one was never the hardcore gamer and have only owned one console, but I loved my N64.
When I moved, I found some of my old N64 games and felt the need to once again play Super Mario World. Unfortunately it stayed with the discovery of the games. My N64 itself is gone without a trace.
Then last week I stumbled “accidentally” on a N64 emulator for Android. It’s called n64oid and is apparently a bit longer on the market. But to me it passed so far.
Anyway, I got spend the $4.99 and have thrown me n64oid on my Samsung Galaxy S2. And what can I say? I’m excited!
Although it runs not all of the roms I […]
