This is an instructable that tells you how to make a computer with a raspberry pi. This is an easy thing to do if you know a lot about this kind of thing. If you know nothing about this, then follow the steps. (I am sorry if any of the pictures are bad.)

Step 1: Parts
Here is a list of parts you will need:
Raspberry pi $35 It is important that you get the model that I have shown. It has 4 usb ports that are crucial to this build. You will not be able to build this with any other model. Shown is model 2.
hdmi cable $5
micro sd card $7 must be at least 8gb
wifi adapter $10
All these items will cost:$121
As of tools, you will need a scissors to unpackage all the items if you get them through the internet.
Now, this is just if you total the price without shipping and handling. All of the links go to Amazon.com. The prices may vary if you get different things than what I have suggested. I do suggest that you buy the lcd screen from the amazon link I have provided.
Step 2: Setting Up Raspian
Raspian is the operating system that I will show you how to download.
- First go to Raspberrypi.org
- Click the button that says "downloads"
- Click on "Raspbian"
- Download zip file for "wheezy"
- When it is done downloading, put it on your sd card by plugging it into the computer and dragging the file to the sd card.
- When it is done, take the sd card and plug it into the Raspberry pi.
- Set that aside.
Step 3: Hooking Up the Screen
If you bought the screen I showed you, then follow this step. If you know how to set up a ribbon cable, then skip this step.
First, take it out of the packaging. There should be a few pieces. The screen, a driver board, a board with buttons, a cable, and a remote. The remote already has batteries in it, so you don't have to check.
To connect the screen to the driver board, pull the black piece on the corners out away from the main board slightly. Then insert the ribbon cable and close it. Be very careful. Also, there is some tape that you will have to remove before you are able to do this. If I have not explained this enough, you can go on youtube to find out how to do it.
Connecting the small board with the buttons should be simple. Connect it to the main board with the cable that is supplied with the other components.
Set that aside in a safe place.
Step 4: Connecting Everything
To start off, plug in one end of the hdmi cable to the raspberry pi, then the other end to the driver board for the screen. Plug the wifi adapter and mouse into the usb ports on the raspberry pi. Plug the micro usb into the raspberry pi. For the key board you will need some adapters. I used this one and this one. Use the adapters to connect the keyboard to the raspberry pi via the usb port.
Step 5: Power
You will need to power your raspberry pi and screen. For the raspberry pi, plug the usb end of the usb-micro usb into a wall outlet. For the screen, it is a bit different. You will need a 2 amp, 12 volt power source. I got mine from Menards.
Step 6: Done
You are now done! Enjoy your new computer. This computer is not a gaming computer. This is a coding computer. It comes with Python, Scratch, and much more! It does come with a early version of minecraft too. I hope you enjoyed reading this. If you have a question, leave a comment. If you make it, leave a picture. Thank you for reading my instructable.
(You do have one extra usb port on the raspberry pi if you want to add a flash drive for extra storage. Or add anything else you would want.)
