Great article but it didn't have <a href="http://xjjbryfh.com">evrh-teingyI</a> didn't find the kitchen sink!
to:
KCHUNG uses small $30 computers called "raspberry pi"'s to do a variety of things, including picking up the stream and relaying it to a transmitter, playing back pre-recorded audio to a standalone transmitter, or pre-recorded video to a monitor (at KCHUNG TV).

a basic raspberry pi kit includes

->the computer itself
->a plastic enclosure for the computer
->a usb power adapter and wall plug
->a usb wifi adapter
->an SD card that holds the operating system and any programs the pi will run

for each specific task, we create a customized disk image that contains the OS and all the necessary programs to help the pi perform its task automatically. this disk image can then be cloned onto an SD card.

'''to configure the raspberry pi to connect automatically to a wireless network (with a connected USB wifi adapter):'''


once you've ssh'd into the raspberry pi, type:

->sudo nano /etc/network/interfaces

edit the text file to look like below. replace "skychud" with the name of the network you want to use, and "solomister207" with the password. (this configuration will still allow you to connect with ethernet cable)

->auto lo
->iface lo inet loopback

->allow-hotplug eth0
->iface eth0 inet dhcp

->auto wlan0
->iface wlan0 inet dhcp
->wpa-ssid "skychud"
->wpa-psk solomister207 

when you're done, hit the control+x keys to exit, type y to save, and save it with the same name (/etc/network/interfaces). when you restart the raspberry pi with the usb wifi adapter plugged in (but no ethernet cable), the raspberry pi should automatically connect to the specified wifi network.



'''to clone / backup an SD card using mac OS terminal and "dd":'''


with the SD card in the mac's card reader, open terminal and type:

->diskutil list

to find which drive is the SD card - it will be about the size you'd expect (8gb / 16gb / etc) and will have a linux partition.

once you've determined which disk it is (disk1, disk2, etc), type:

->sudo dd if=/dev/rdisk2 of=/path/to/backup.img bs=1m

(change "rdisk2" to the correct identifier for the disk you want to back up) 

…wait for the backup process…

or... if you want to backup directly to a compressed file, use this command instead:

->sudo dd if=/dev/rdisk2 bs=1m | gzip > ~/path/to/backup.gz


'''to make a new SD card from a backed-up disk image using mac OS terminal and "dd":'''


with the new SD card in the mac's card reader, open terminal and type

->diskutil list

to find which drive is the SD card - it will be about the size you'd expect (8gb / 16gb / etc) and will have a linux partition.

once you've determined which disk it is (disk1, disk2, etc), type:

->diskutil unmountDisk /dev/disk1

(change disk1 to the correct identifier for the disk you want to copy onto)

then, to begin copying from a backed-up image type (changing the disk identifier "rdisk1" to the one matching the SD card):

->sudo dd if=/path/to/backup.img of=/dev/rdisk1 bs-1m

(again - and this is '''critically important''' - change rdisk1 to the correct identifier for the disk you want to copy onto)

OR if you are backing up from a compressed disk image (.gz), type:

->gzip -dc /path/to/backup.gz | sudo dd of=/dev/rdisk1 bs=1m



…and wait for the process

Will there be a grant for those of us who are teaching educators how to use YouTube for inticurston? I doubt if the work I do teaching educators will reach the popularity needed for partner status. Just consider this a plea from one university prof quietly teacher her students the benefits of YouTube and digital video for education.
