How to get started with Raspberry Pi!

In this post, I will show you how to get started from scratch with Raspberry Pi.

Please ensure that you have the following items to get started (All items are in the Amazon links below for easy purchase and checkout)

1) Raspberry Pi B+

2) Micro-USB Charger 5V-2Amp

3) 8GB Micro-SD Card (Class 4 and above) (4GB or more) OR NOOBS SD Card (see link below)

4) HDMI TV / Monitor OR DVI/VGA Monitors with relevant adapters

5) USB Keyboard

6) USB Mouse

Optional:

7) Wireless Dongle (WiPi) OR Ethernet cable

8) Raspberry Pi B+ enclosure


All items are down in the Amazon Link and is within USD$100 (excluding Monitor & Casing) which is highly suitable for people with tight budget:

Steps to begin:

1) Prepare your Micro-SD card with NOOBS. (Click on NOOBS to download)

2) Extract the contents of NOOBS and drag into your Micro-SD card.

3) After the copying is complete, remove the card from the computer and insert it to the underside of your Raspberry Pi.

4) Now, plug in the HDMI cable that is connected to your monitor to the HDMI port of your Raspberry Pi.

5) Plug in your USB keyboard and mouse.

6) Plug in your Ethernet cable if you have any.

7) Plug in your Micro-USB charger to your Raspberry Pi and connect it to your wall outlet.

8) Turn on your power source and you should see your Raspberry Pi booting up for the first time. If everything is successful, you should see a long list of command lines appearing on your screen. If you do not see anything, please check that all your cable connections are connected correctly, and also check that the contents of the Micro-SD card contains the files of the extracted NOOBS folder.

9) You will be prompted to make some changes in the utility setup for the first boot up. Make the correct changes (eg Date, time, region) in the utility settings. Once you're done, you see your Desktop of the Raspberry Pi.

10) You have now successfully completed setting up your very first Raspberry Pi! Congratulations!

Raspberry Pi B+ is here!

Just got the Raspberry Pi B+ from element14!

Transitioning from the Model B to the new B+ poses new challenges.

1) Memory card type is different. My old SD card that I'm using for the Model B could not be used, since the new model only uses Micro-SD card. Migrating data over from one storage card to another is time consuming.

2) Due to the new 40 pin GPIO, the Adafruit Cobbler Kit for the Model B cannot work with the new model. Adafruit has introduced the new Cobbler Kit Plus that is dedicated to the new 40-pin layout of the B+ and has brand new layout with new schematics and functionality.

However, for users who still owns the old Cobbler Kit, Adafruit provides a way to resolve this. They introduced a special GPIO cable that downgrades the 40-pin connection to the 26 pin connection so that they can connect to the old 26 pin Cobbler Kit.

For those out there interested in knowing the difference between the old and new Cobbler Kit schematics, the pictures are down below: (Top is New) (Bottom is old)
