Getting started with the Raspberry Pi (without the basics)

Hey blog readers! we have a new Facebook page! Check it out at

Hello blog readers! Sorry I haven't been posting in a while. I have been busy with the raspberry pi. As you can see in the attached photo, it's a mess! I brought it to school and a few people called it a time bomb. But the picture is my home setup. On the go, I just bring the two power bricks (one for the screen and one for the pi), a keyboard, a mouse, the tiny 3.5 inch screen, the pi, and a cat5e cable. And I somehow fit all that in my backpack. Some things I did when I got started was:
1. Expand the root partition to fill the SD card. Type the following (or on first boot, it should display automatically)
sudo raspi-config
hit the down arrow to "expand root partition". Then hit enter on the yes option as needed.
2. Boot to the desktop. In the raspi-config, go to "boot to desktop", then hit enable. Then, when you get back to the main menu, hit finish, then no.
3. Enable sound
Type sudo apt-get remove pulseaudio
Then hit Y as needed to remove the stupid sound manager that does nothing but screws up the sound.
4. Make it talk
Go ahead and reboot (type sudo halt then unplug the pi, count to 5, then plug it back in). When you boot to the desktop, double-click on LXTerminal. Then type in the following:
sudo apt-get install espeak
Hit Y as needed. When you are done and it shows the pi@raspberry$ prompt, type this in:
espeak ["hello"]
Plug in some speakers and hit enter. If you just hear static, you need a sound config redo (google it, too many sites can tell you how to fix it). If you hear a heavily accented voice say hello, good job! You can now replace hello with any text that you want.
5. Install minecraft
Go to and follow the instructions there. And please note: the multiplayer function only works with the mobile versions of minecraft (for iOS and android)
6. Play quake (sort of)
On the desktop, double click on the Pi Store. Go to the games tab, and click on openarena. When you click download, you will need to register for an indiecity account. When it is finished, you can hit play. But, for anyone who wants to play it while they aren't connected to the Internet (or just want to launch it the hard way), press control-alt-F1. Then at the prompt, type in openarena. It should work. Note: if you suddenly start hearing crackling sounds, hit escape, then go to setup, then sound, then change the sound quality, then the arena (and the sound system) should reset. Then it works! Please note that you cannot play against PC servers, only pi servers.

Well, Have Fun!
