OFFICIAL OCN RASPBERRY PI OWNERS CLUB!
Disclaimer: I am in no way an electronics wizard or a programming junkie. I'm a typical "IT guy" who loves to tinker with this kind of stuff. I am creating this club for community/collaboration purposes to discuss and share projects, ideas, etc.
What's a Raspberry Pi?
The Raspberry Pi is a credit-card sized computer that plugs into your TV and a keyboard. It's a capable little PC which can be used for many of the things that your desktop PC does, like spreadsheets, word-processing and games. It also plays high-definition video. We want to see it being used by kids all over the world to learn programming.
Where can I buy one?
You can buy the Raspberry Pi through
Premier Farnell/Element 14 and
RS Components. Both distributors sell all over the world. You can also obtain one through
eBay but you'll pay a premium.
Update: You can get a Raspberry Pi (1-2-3-0) from just about any major electronics retailer anymore (Amazon, Newegg, Tiger Direct, etc.)
What's the difference between all the different models?
Model A has 256MB RAM, one USB port and no Ethernet (network connection). Model B has 512MB RAM, 2 USB port and an Ethernet port. Model 2B has 4 USB and a quad core CPU @ 900MHz. Model 3 now has built in WiFi and LE Bluetooth plus a 1.2GHz quad core 64-bit CPU. Pi 2 and 3 also utilize a Micro SD card instead of full sized SD like 1st gen Pi's.
Cost?
Model A - ~$25
Model B - ~$35 (now much cheaper if you can find them)
Model 2B - ~$35 (price will likely go down/expect deals since the 3 is out)
Model 3B - ~$35 (a little hard to find at this point, expect to pay $5 or so for shipping)
Model Zero - $5 (good luck finding this guy in the near future, nearly impossible to find without price gouging)
What's needed to get started
*Micro USB charging cable (5 volt 1000mAH/1A or higher is recommended) (5V 2.0 AMP is the minimum recommended for models 2 and 3 now)
*HDMI or Composite Video cable (the yellow one)
*Keyboard/Mouse or HTPC remote with USB receiver
*SD Card 2GB or higher (SDHC Class 6 and above cards preferred)
SD Card Compatibility List (thanks to Ardalista)
*Case for the board is optional but I wouldn't want to finger it up repeatedly for ESD reasons.
*Monitor with HDMI support or TV with composite input.
*Ethernet cable (needed for some OS's to boot up properly)
Accessories
Cases, Starter Kits, Etc.

Again guys, by all means lets get some input into this. I am only a beginner myself and would love to see some contribution to this club.
