Tutorial: Host your own Minecraft server


Category : Minecraft

Why not?

First off we need to download the server software, you can find it here. Look further down on the page and you’ll see a link to a Minecraft_server.exe, thats the one you need. Download it and put it in a folder, lets call it Minecraft_Server.

Now lets run the .exe file you just downloaded so that it creates the config files, and close it when it’s done generating the spawn point. Now your folder should look something like this.

world = the server map, it’s just been autogenerated.
banned-ips.txt = the list of banned IP adresses.
banned-players.exe = banned users.
ops.txt = server operators, users that can kick and ban etc.
server.log = the logfile.
server.properties = server settings, this one is important.

Before we go and configures the server properties, we need to open a port on your router or whatever your behind. Find the routers IP adress, easiest way is to enter cmd.exe and write “ipconfig”. Then look at whats the default gateway. Mine is

So just write the ip adress in your browser(Firefox, Chrome etc) and log on to the router. In this tutorial I’m using a Dlink DIR-655, but it’s done almost the same on most of the routers out there. Click into Advanced, and find Virtual Server. Check the check-box and write the name of the port, just whatever you want to call it. Fill in your computers IP, it can be found the same way we found the routers address, just look for IPv4 Address. Set public and private port to 25565, which is the default minecraft-server port, protocol select both. It should look something like this:

Now just run the server .exe and it should be up and running! When thats done, you can check with this page that the port you opened is open. Of course there are many mods and server managers that are way better than the default one, but at least you get the idea of how you host your own server.

Any questions, or something I forgot? Post a comment!

Thinking about starting with Arduino? Read!

I just want to write a few words for those new to Arduinos, or those looking for tutorials, guides etc. If you haven’t got a Arduino board yet, you can get one from several places, I’ll list some of my favorite shops. And of course you also need the Arduino Software!


Or, Modified Electronics for the great Pico! (not recommended for beginners, you’ll be better of with a normal board).

What you are looking for is the Arduino Duemilanove, the USB board. Which will suit most your needs. It’s very easy to use, and wires can be plugged right into it. Later on you might want a Boarduino or maybe a Pico as mentioned above, they are great for using in combination with breadboards! Alternatively you can get the Starter kit, almost all shops got these. Sparkfun got a nice kit, which is worth a look.

If you should want more I/Os, or just more space for code the Arduino Mega is a great choice! Or the Sanguino!


You will always need parts, resistors, leds, breadboards, wires etc. I’ll list up a few shops that I use the most.


Lots of cheap basic parts! recommend the resistor packs, and they also got cheap breadboards. And all of the shops mentioned above stock parts too. For jumper-wires I recommend these at seeedstudio. Futurlec also got some nice jumper-kits. For extra small breadboards these at Seeedstudio are very nice!


Great site for robotics, motors, gearboxes etc. They also got a nice tracked chassis. They got a lot great products, sensors, motor controllers, etc.


1. The basic guide, from sparkfun. You should start with this!

2. The Complete Beginners Guide to The Arduino

3. Adafruit’s Arduino Tutorials

4. Arduino.cc`s Tutorials

5. Arduino.cc Reference! Not tutorials, but handy!

Also the Libaries page at Arduino.cc is great! I’m sure you’ll find something to use in several projects!

Well, thats all I’ll write for now. I’m sure I left out alot, and will update this post when I find something new to add 🙂

PS. If you got any questions etc, please take it in my forums post here.
