SD CARDS
After downloading the disk image "reveil-pi-nov-2014.img.zip", you need to uncompress it and copy it to a new 8 GB Class 10 SD Card.
Locate the file and double click to uncompress it.
Download and install Pi Writer for Mac OSX. (More Pi Writer info)
Open Pi Writer and follow instructions to flash the disk image to your SD Card. Bear in mind that this may again take a long time, and the progress bar in Pi Writer doesn't work. However, the application will report when it is complete and you can eject the disk.
For Windows, see these instructions at Adafruit
If you plan to stream with WiFi, you need to enter the name and password for your own WiFi network: Insert the SD card in your computer's card slot or a USB SD Card reader. It appears as a disk called "boot". Open the file "wifi_settings.txt" with a text editor and put your wifi details into the fields ssid and psk, keeping the quotation marks. Save the file and close it and eject the disk.
If using an ethernet connection, you can go ahead with the next step.
Insert the SD card in your Raspberry Pi. Connect your WiFI adaptor (if using; otherwise, remove it) and your USB soundcard and microphone.
Plug in the Pi using a 5V USB power supply, preferably with a rating of around 2100mA.
The Pi will boot and will appear in the Mac OSX Finder sidebar along with other devices on the network. You can make adjustments to the Pi's settings by clicking Connect and entering the username: pi and the password: soundcamp
The main things you may want to do initially are adjust settings for the soundcard and microphones you are using. You may also want to adjust the gain on your soundcard. For some settings changes to take effect, the Pi needs to be restarted. See below.
Instructions to adjust your streaming settings
SHUT DOWN AND RESTART
Restarting and shutting down the Pi safely is a slightly involved process. Simply turning off the power can damage the SD Card, so it is advisable to use the following method.
The approach here involves interacting with the Pi remotely, rather than connecting the Pi to a monitor and keyboard. In some cases, including shutdown and restart, this means logging into the Pi using the Terminal. In case you are not a seasoned Terminal user, don't worry; it's simple.
Still connected to the Pi, use a text editor to open the file "Home Directory/Desktop/ip_address.txt" and copy the IP address of the Pi which is reported there.
Now open Terminal. In the Terminal window, give the following instructions to log into the Pi remotely via SSH. Type:
ssh pi@pastetheIPaddressofthePi
Then press Enter
You are asked if you are sure you wish to proceed. Type:
yes
Then press Enter
You will be asked for your password. Type:
soundcamp
Press Enter
After a moment, the command prompt switches and you are now logged in to the Pi. From here you can do various things. For now we want to do one of two: restart the Pi or shut it down
To shut the Pi down, type:
sudo halt
Then Enter
You will be told that the Pi is shutting down. Wait for that to happen, and lights to stop flashing on the Pi, before disconnecting the power.
If, instead, you want to restart the Pi, type:
sudo reboot
Then press Enter
You will be told that the Pi is shutting down. Once that has completed, it will re-start.
NB: Occasionally the Pi may become unresponsive when running 'sudo reboot' or 'sudo halt'. In that case, run the command again. The Pi will then reboot or halt, although it may appear to hang with no output. You can then proceed, if necessary by closing the current and opening a new Terminal window.
To end your SSH session and log out of the Pi, type:
exit
Then press Enter
The command line changes to that of your local machine.
