Embedded System - Raspberry Pi
Before You Buy ?
Before you go and buy a Pi, first you need to think of what other components you would need to make it fully usable to you.
When I first heard of Raspberry PI saying 'you can get it a fully funcitoning PC with just $35(USD) , I was strongly tempted to buy it right away.. but I've been holding it back for a long time after I saw a couple of YouTubes show the whole components and procedures you would need to get.
In most of the YouTube video about Raspberry Pi setup, you would realize that you would need all the components as in Case 1 shown below. If you don't have any extra Monitor, Mouse, Keyboard etc, you would need to buy these to use Pi and it would cost much more than Pi itself. I didn't like this option for two reasons. First, I didn't have those extra components at home since I am using Laptop only and have no LCD, Keyboards, Mouse. So I need to buy all of these if I use Pi. Second, even if I have the extra LCD, Keyboard/Mouse, I still does not like case 1 since I would play with Pi on the move (e.g, on business trip or coffee shop etc), or on the bed (my regular workplace :)). So I want to check if I can use the Pi in Case 2 configuration. Only recently I figured out how to start Pi with Case 2 and decided to buy it and try. Even this configuration (simpler than Case 1), I've spent around 85 USD in total as of Aug 2018.
