Picture of LapPi - A Raspberry Pi Netbook

The Raspberry Pi is a remarkable machine. Lightweight, powerful, and until now it was completely tethered to a wall socket. The LapPi is built to free the Pi! It's made from a mixture of spare parts, unallocated electronics, and scrapped components & cables I have built it in response to the Raspberry Pi Challenge. The challenge was picked up on the 15th of October via retweet from @raspberry_pi, and by the end of the day I knew what I wanted to do....

The basic idea is simple. Put a Raspberry Pi inside an aluminum case, wire it up to a screen, keyboard, mouse & batteries. Then plug in a USB hub, connect Wifi, Bluetooth, and the receiver for a wireless keyboard. We will also need to extend the Network port, add a headphone socket & speakers, fit in a battery pack, and then wire it all together! Simples.


The LapPi made joint second in the Raspberry Pi Challenge! Congratulations to the other winners, and well done to everyone who entered.

I have used a 7" LCD panel & logic board. It has HDMI, VGA, Composite & 2 AV inputs. For the purposes of the LapPi we will only be using the HDMI connection. The logic board also has a menu board with buttons to select inputs, & configure the LCD panel. The panel is 800x480 with LED backlights, it requires a 12v feed.

Before I began work I checked that the Raspberry Pi worked with the screen. I also configured the display's resolution, and made a funky desktop picture.

Components used;

1 x Raspberry Pi.
1 x 8gb SD Card.
1 x Raspy Juice Expansion Board.
1 x LCD with Logic Board & Menu Board.
1 x Aluminum Case.
1 x 4-Port USB Hub (powered).
1 x +5v 1a LDO from Flytron*
1 x USB GPS Dongle.
1 x USB WiFi.
1 x USB Bluetooth Dongle.
1 x Mini USB 2.4ghz Wireless Keyboard & Track-pad.
2 x Mini Speakers.
1 x Microphone Socket.
1 x Ten AA Battery Holder.
10 x NiMh 1.2v AA Cells | or | 8 x Alkaline 1.5v AA Cells.
1 x Panel Mount USB Socket.
1 x Panel Mount RJ45 Socket.
1 x Panel Mount 2.1mm DC Socket.
1 x Double Pole Double Throw (DPDT) Slide Switch.
1 x HDMI Cable.
1 x IDE Cable.
1 x Network Cable.
2 x Metal Mesh.
1 x Passive Heat-sink.
3 x Sticky Foam Strips.
1 x Ringed Tie-Wrap.
1 x Standard Tie-Wrap.
1 x Tie-Wrap Sticky Block.

I have removed the casings from the USB dongles, the USB HUB, and de-soldered the USB dongle plugs.

The battery pack will provide 12v if used with 10 1.2v NiMh Rechargeable batteries. To get 12v from standard alkaline batteries you will need only 8 cells, as Alkaline non-Rechargeable cells provide a higher output of 1.5v. The LapPi is designed to operate on 12v.

It is worth noting that not all USB devices are compatible with the Raspberry Pi. The elinux.org wiki contains a list of verified compatible peripherals.

UPDATE: In Step 14 I replace the underpowered LDO with a 15w DC-DC Converter & fit a 2x1watt Stereo Amplifier.

Additional parts used for the update;

1 x DC-DC 15w 12v-5v 3A Converter.
1 x RK Education Stereo Amplifier.
1 x Switch (DPDT).

Great project! I love homemade raspberry pi laptops ;)

Here's is a good webstore to buy the parts that you are using in your project: http://voltatek.com/en/7-raspberry-pi

I also am in need of a screen or a power source for my screen

how curious I am currently working on a raspberry pi laptop I call it the pi-top

Cool!
I'm been thinking about making a raspberry pi umpc using a sylvania 7 inch laptop like the ones you can get at cvs pharmacy as a case. Does anyone know if the rpi will fit and if the circuitry such as the screen, battery pack, keyboard, ect. would work?

UMPC stands for ultra mobile personal computer. (kinda like the open pandora)

with that said please dont tell me about the red and black 3d printed cased one else has made, because that one is bulky and doesn't fold. i would try to build something much sleeker and more expensive looking.

What is this capable of? How much can it handle? Btw nice design mate.
SilverJimny (author)  codie2810 months ago
It can do whatever a Raspberry Pi inside an aluminium flight case can do. Really it's a case of what can you do with it.
tomzbeast10 months ago
mate I will pay you cash + your time can you please make me one absolutely amAZING
How big and how heavy is the final product?
Nicholaslupo111 months ago
Can you make me one? I will pay US dollars, name your price, I will pay for shipping and handling, I you want to make it! Thanks for listening, and bless your face! If you sneezed while reading this bless you, email me at nicholaslupo1@gmail.com

I scrolled already trough a billion pages on all diffrent sites how much did you pay for the case?
SilverJimny (author)  dennisbengel1 year ago
£24.99 for 3 cases of different sizes. They were from Maplin.co.uk, but I can't find them listed any more.
Where can i get a cheap aluminum case
SilverJimny (author)  dennisbengel1 year ago
eBay?
What is the weight with everything in it

Great project
Could someone please email pdf instructions as I am not a Pro memeber
tybow991 year ago
Very nice! I have just ordered my Pi, and am interested in a laptop build. I like the fact that this one requires no 3d printing. I think i might give something like this a try!
romance,
your doing it right.

One other thing came to mind...have you considered a solar panel for additional charge (small marine ones should have enough to keep it going and charge it for a good while).
nephilim2k1 year ago
Have you thought of adding a portable CD/DVD/Blu-Ray drive and cutting out a section of the case to mount and hold it?
SilverJimny (author)  nephilim2k1 year ago
There isn't any room left. It might be possible to sqeaze something into the top lid, but that's pretty chocker too.

What hobby store / web site did you use to get the boat stuff. I like model boats and much enjoyed building a $3 danish kit (wood) about 47 years ago. I think those danish kits are now in the $700 range. Thanks. Alvin....
SilverJimny (author)  schmitta1 year ago
Hello Alvin,

All the parts I bought, including the hull, are linked on step 1;

I agree with "oldmechanic" it is a good idea
SilverJimny (author)  nerd74731 year ago
Thanks to you both, I wish I had a larger screen it looks a bit overwhelmed by the frame.
your welcome
Oh man, I love this! Amazing work
Where did you get all the components? I can't even find this stuff on ebay!
