Introduction: Netbook Laptop Build for $ 160 - Raspberry Pi Powered.
Hey Everyone! I'm 13, and I was inspired by online projects and cool computer builds to see if I could build a laptop. This may not be the greatest tutorial ever, but this laptop has 512 mb of ram, a 1ghz processor, with wifi, around 4 gb of space. but it's only 160!
Step 1: Overview of Parts
Ok, so here we go
these are the general list of parts needed, I'll list what I used and the general object too. I found all my supplies except the casement on Amazon
1 portable battery
I used an Opteka 6000 mah solar
2 usb hubs, 1 large, 1 small
I used a 4 port generic usb hub seen in pic and a 4 port travel mini one by HDE
hdmi input screen
I used a tontec 7" raspberry pi screen, non touchscreen
you need a usb to microusb cord for the computer, which is very common, just search it. for the screen, the tontec screen took a 2.1mm usb to DC power cable
hdmi cable - any brand just normal hdmi
keyboard and mouse
I used a gearhead mini sub keyboard and a wireless mouse I had lying around.
paneling to hide the wires - I cut up an old 3 ring folder binder
I bought one off Amazon, use the b or b+ for full power
micro sd card
I'd recommend 8 gb and a class 4, if you have a type a pi make sure it has a ad card adapter
just a mini wifi adapter, usb and small.
edimax has one on Amazon ideal for this
and the laptop case
I'll get to this at step 5
Step 2: Step 1 - Do a First Time Assemble
don't worry about the case yet, well just do a first time assembly
if you used the tontec screen, Google how to attach the screen to the driver board
ok so connect the mini usb hub to your battery, which should be off, then plug the microusb cord and the usb to (whatever power input your screen takes, in my case usb to dc) cord into the mini usb hub
set down your raspberry pi and plug the micro usb cable into it, and set down your screen and plug it it's power source cord
connect the hdmi cable from the screen to the raspberry pi
then connect your larger usb hub and wifi adapter and mouse and keyboard to the raspberry pi.
now before we power it on, you need an OS, so here's that step
Step 3: Add an OS to the Computer
Ok so here we go
your laptop is not going to run Windows or Mac. there, I said it.
But this computer will be able to run multiple other OSES, including android, Linux, and Risc Is
I recommend Debian Linux Wheezy, as seen in the picture above. a special version for this laptop is avaliable, Google Raspbian OS
This is how to install wheezy
you need a windows for this
ok so download Wheezy from the Raspbian source, it should be a zip or img file, if it's a zip extract the img file inside of it.
install Win32DiskImager from online and run it. plug your microsd card into the computer using an sd card adapter, and check the drive letter. select the drive letter in win32, and browse and select the img file - should be called something like wheezyrasbian.ing
then click write in win32, and when it finished eject the sd card and remove the microsd from it
Step 4: Easiest Part! Boot Your Computer for the First Time
take your microsd card and insert it into the slot on the bottom of your raspberry pi. then hit the power button on the battery. Moment of truth! if your screen turns on and shows something like above, you did it all right
Your Battery output is too low, it needs to be at least 5v 2a for my setup
You screwed up attaching everything! so common. just re read my directions
you installed the wrong OS or installed it wrong
I can't really help you here, as you already wrote the card. Sorry?
Step 5: Mount the Screen
so I don't really know how you want to mount your screen, but here's the best way for the tontec screen
ok, you need a hot glue gun for this step. I hate tutorials that require soldering, so I promise this needs none of it
ok so use the little button board, not the driver board, to set the screen orientation to upside down
then hot glue the driver board to the back of the screen near the top, MAKE SURE the screen connector is on the same side
then plug the screen in to the driver board and use the mini screen button connector thingy to make final edits to the brightness, ect
now we are going to mount this to the back. as you can see in the picture above, you can't just glue it as is because of the irregular shape of the back. My DIY solution was to cut up popsicle sticks and build them into supports so I can glue it
when you glue it be sure to plug in the hdmi and DC cable first, and have them facing down
for the casing, I don't have any link for you, because I used an old card case, but cases by source on Amazon has good ones and you can pick a size ideal for your parts
Step 6: Mount the Battery, Computer, and Usb Ports
so if you haven't already, plug in your wifi adapter to one of the usb ports
stick everything inside your case and make sure everything's connected
stick everything in and hot glue whatever you need down, and panel it over with your material, plastic or cardboard, etc
use an exactoknife or a drill bit to make holes for connections, decide what connections you want to be a valuable, I didn't show any usb ports and just showed the usb hub.
then cut a 2 by 2 cm hole in the side for proper airflow
attach a mouse and keyboard, or a keyboard trackpad to it
make sure that the button to start the battery and the charge for the battery is exposed
and your done! you now have a Linux laptop for only 160 bucks
