Raspberry Pi 2 Hands on Review

Raspberry Pi 2 is the Latest Version of the Raspberry pi family.

Got it Delivered from Crazy Pi On 10th Feb 2014, shipping was done very fast by them.  Buy From Here : Link

First Review 

The boot time was pretty fast , almost 7 seconds . It is equipped with a 900MHz quad-core Broadcom BCM2836 CPU with 1GB DDR2 RAM with makes the whole thing run Fast . Its claimed that its 6 time faster than the previous one. It have 4 USB ports as the Previous version (B+) have  and 10/100T Base Ethernet.  Another happy news is Windows recently told that the are gonna provide Windows 10 for Raspberry pi for FREE .

For Wifi connection the same settings as previous versions of the pi can be used, Ubuntu version for Raspberry Pi is also released and can be downloaded form Raspberry Pi website .

First Test 

Inserted OLD SD card (used on Raspberry pi Mode B )   -> Not Working

Downloaded the image from raspberry Pi website -> It worked

Raspberry Pi restarts when exposed to Xenon Flash Link

WIll Post the results about tests conducted on it soon.

WiFi to Ethernet using Raspberry Pi

You can use your PI as a router to share the ethernet connection to  WiFi Devices , What about the other way ?

Here is tut for Ethernet to WiFihttp://elinux.org/RPI-Wireless-Hotspot ( This tut helped me to get idea )

Requirements

  • A Raspberry Pi, model B.
  • A boot SD card for the Raspberry Pi.
  • Connected to Networking Via WiFi
  • An Ethernet cable to connect PC

Assumes that you have connected your device via WiFi and ssh logged in using WiFi .

If wifi is not setup perfectly please see this one :

Wifi auto connect : http://blog.arevindh.com/solved-raspberry-pi-wifi-disconnect-problems.html

Instructions

1. Install the necessary software.

2. Configure DHCP. Edit the file /etc/udhcpd.conf and configure it like this:

Edit the file /etc/default/udhcpd and change the line:

to

You will need to give the Pi a static IP address with the following command:

To set this up automatically on boot, edit the file /etc/network/interfaces and replace the line “iface eth0 inet dhcp” to:

If the line “iface eth0 inet dhcp” is not present, add the above lines to the bottom of the file.

Configure Your WiFi

3. Configure NAT (Network Address Translation). First, enable IP forwarding in the kernel:

To set this up automatically on boot, edit the file /etc/sysctl.conf and add the following line to the bottom of the file:

Second, to enable NAT in the kernel, run the following commands:

Your Pi is now NAT-ing. To make this permanent so you don’t have to run the commands after each reboot, run the following command:

Now edit the file /etc/network/interfaces and add the following line to the bottom of the file:

4. Issue commands to start the dhcp server:

Your Pi should now be hosting a ethernet hotspot. To get the hotspot to start on boot, run these additional commands:

Reboot  Pi and plugin the LAN cable and you can see the auto allocated ip on command ipconfig (on windows) / ifconfig (on linux).

Buy Raspberry Pi Model A Plus India

The Raspberry Pi Model A+ is the perfect board for the minimalist Pi fan. This low-cost Pi uses the same processor as the model B+, but does away with the Ethernet jack and three of the USB Ports. This makes it lower power, less expensive and much lighter & smaller! It’s still compatible with all Pi operating systems and software, and has the exact same 40 pin GPIO connector and camera/display sockets, so any HATs or Pi Plates or other things that plug into the model B+ will work just the same.

It also has the same HDMI, sound/composite connector and micro USB connector for power.

Unlike the Raspberry Model B+, there’s only one USB port and no ethernet jack but it’s also significantly smaller at 65mm x 56mm if you don’t include overhang from the connectors. Also, there is only 256 MB of RAM onboard instead of 512, so if you have a RAM-intensive application you may need to stick with the B+
