How to install Raspberry Pi Minecraft: Pi Edition (Tutorial)

October 12, 2013

In this tutorial I aspire to provide a simple, easy-to-follow tutorial on how to install Minecraft: Pi Edition onto your Raspberry Pi. For this tutorial, you will need the following resources:

If you don’t have the aforementioned equipment, the Kano kit is the perfect cost-effective kit to get started with the Raspberry Pi. You can get yours at www.kano.me.

Note: in addition, you may also need a mains-powered USB hub to prevent overloading the Pi electronically with peripherals. Let’s get started…

1.) Firstly, you need to boot up your Raspberry Pi, set it up via raspi-config to your liking, and then type:

startx

…into the Terminal to boot up the desktop environment. From the desktop environment, select LXTerminal. A terminal window will open. This step is important because these instructions do not work in the normal Terminal that you see upon booting.

2.) In LXTerminal, type the following code to update & upgrade your Raspberry Pi. It’s good practice to do this regularly.

sudo apt-get update
sudo apt-get upgrade

3.) Now you’re all up-to-date, you can go ahead and install the Minecraft: Pi Edition files.

wget https://s3.amazonaws.com/assets.minecraft.net/pi/minecraft-pi-0.1.1.tar.gz

4.) Once the download has completed, you should unzip and extract the files.

tar -zxvf minecraft-pi-0.1.1.tar.gz

5.) To open, navigate to the mcpi directory:

cd mcpi

And to open the executable file:

./minecraft-pi

Have fun with your new Raspberry Pi Minecraft: Pi Edition installation! ;)

Raspberry Pi Webcam Server Tutorial (Live Stream)

August 11, 2013

Raspberry Pi Webcam Stream

One of the more popular Raspberry Pi projects is turning your board into a webcam server capable of hosting a live stream. Most people would utilize this as a CCTV system (I plan to) however others will have unique uses. If you have some weird yet wonderful idea, be sure to let me know about it! I think this is accomplishable for about £40/£50, however I used a few bits and pieces that I had lying around and was able to put this together for practically nothing. I used a Logitech Quickcam webcam for this project.

What You’ll Need:

• A Raspberry Pi (obviously)
• An SD Card (about 8GB)
• A webcam
• An Ethernet Cable or a WiFi Adapter (Wireless Adapter) and Internet Access (duh)
• A powered USB hub
• A keyboard
• A mouse (if you chose a WiFi Adapter)

Okay, so first we’re going to need to get a fresh install of Debian “Wheezy” onto an SD Card – this is obtainable from the Raspberry Pi website for free. You can put this onto an SD Card using Win32DiskImager for Windows (http://ow.ly/kGAo1) or there’s a dedicated app for Mac that can do this for you from this website: http://ow.ly/kGABi

Once you’ve done that, insert the SD Card into your Raspberry Pi. Connect either an Ethernet Cable or your Wireless Adapter to your board and the Keyboard. Oh, and don’t forget your externally-powered USB hub.

Turn on your Raspberry Pi, set the time zone according to where you live from the Raspi-Config menu and then hit Finish.

Log in if prompted.
Username: pi
Password: raspberry

Before you do anything, you should update your password from the default to prevent intruders. To do this, you should type sudo passwd into the command line. Type a new UNIX password, and you’re ready to go!

- IGNORE BELOW IF USING AN ETHERNET CABLE -
If you want to set up your wireless adapter and connect to WiFi in the desktop environment, you’ll need to type in the following to the terminal:

startx

You can then set up your wireless connection here. Once finished, click the menu in the bottom left and then ‘Log out’ to return to the command line.
- IGNORE ABOVE IF USING AN ETHERNET CABLE -

Now you need to upgrade your system. At the command line, type:
sudo apt-get update
sudo apt-get upgrade

And wait for that to finish. Now we need to install Motion – this is the streaming software that makes everything work with a build in web server. For that, please enter:

sudo apt-get install motion

And wait. After installation, please plug in your web cam via the powered USB port. Without the external power boost, your Pi may not be capable of powering the webcam on its own.
You need to edit the Motion configuration file to make it all work, so enter the following code in the terminal:

sudo nano /etc/motion/motion.conf

Your configuration file will appear, and you can change a few settings here if you like. Most importantly though, we need to change the following:

• daemon OFF (to ON – this can be changed near the top of the file)
• webcam_localhost ON (to OFF – this can be changed near the bottom of the file)
• control_localhost ON (to OFF – located just below the above setting)

Do Ctrl + X to save, type ‘y’ to save save modified buffer, and press enter to confirm the file name.

Now you need to enable the Daemon to start by typing:

sudo nano /etc/default/motion

…and changing start_motion_daemon=NO to start_motion_daemon=yes

Now we need to start the Motion server:

sudo service motion start

Wait for about 60 seconds and then navigate to your Raspberry Pi’s internal IP address (visible on startup of Pi) in your web browser. The latest versions of Firefox work best.

It should look something like this: 192.168.X.X:8081

Make sure you include port 8081 at the end, as this is where your webcam images will appear. You can configure your setup in a web-based interface from now on by connecting to port 8080 instead of 8081.

Port 8081 – video
Port 8080 – web configuration interface

Note: this is only visible on your own WiFi network. If you attempt to view it on a different Internet Connection, it will not work. You can enable Port Forwarding in your router’s GUI to enable global viewing.
Congratulations! You’ve just made your own Raspberry Pi Webcam Server!

Troubleshooting Guide
Does your stream give a grey screen with an error relating to your webcam?
Type ls /dev/video* into your terminal to find out the name of your video device. The default in the /etc/motion/motion.conf file is normally video0 so if you get a different output then it may require changing. Restart the Motion software to apply changes.
