Now that you have your nifty new Raspberry Pi, you'll need a display for
it. Teensy analog monitors are pretty cheap, but what you really want is a
decent HDMI display. Unfortunately, they're expensive, running from
$150 on up into the thousands for the huge ones. But, for about $75
(or even as low as $40, used, on eBay) you can get a discontinued
model of the notorious Motorola Atrix Lapdock, the one that sold for
$500 a couple of years back, and it was a bargain at that price. The
lapdock incorporates a razor-sharp 11" HDMI display, an almost-adequate
keyboard-with-trackpad, twin speakers, and a high-capacity battery --
all in a thin two-pound package.



The Atrix Lapdock was manufactured to mechanically connect with the
now-discontinued Motorola Atrix smartphone, in effect turning it into a
laptop computer. The lapdock has two plugs on a foldout hinge -- a male
micro-HDMI plug and a male micro-USB-A plug. These neatly mate with
an Atrix phone, slipping right into appropriately positioned jacks on the side of the phone.
Fortunately for us, the lapdock's USB and HDMI ports are electrically
standard, even if the physical connectors aren't. If we could just find the
correct cables and adapters, we might be able to hook up our Raspberry Pi.
Maybe. Hopefully. . . .

Yes, it can indeed be done!

See

for example.

In this Instructable I will break down the process in detail, with
appropriate explanation and close-up pictures.

how would i be able to hide the raspberry pi inside the laptop? also, does it power itself AND the pi? just wondering.

thegrendel (author)  Crafterkid12329 days ago
1) Can't hide it inside the Lapdock, as far as I can figure. Not enough room.

2) The Pi needs 500+ ma, and therefore its own power supply,
otherwise it will not operate reliably.

Thank you for this article. I like this project! http://www.einplatinencomputer.com/der-raspberry-pi-laptop/

Sorry, but I'm not in a position to do this.
And, I'm not in Toronto.

Hey i am also in Toronto. Very cool projects you have. Would you be i nterested In a paid project? Need something done right away.
I just tried to build this combination of RasPi and Lapdock. Well, the RasPi boots, so it is getting enough power through usb. I do also see everything on the display.

But the keyboard and also the touchpad do not work. What may be the problem?
thegrendel (author)  yvandercoilden8 months ago

Check the USB adapter/cable.

will any of the other motorola lapdocks for other phones work with a raspberry pi? I'm looking at Droid Bionic and Droid RAZR Lapdocks on ebay, they appear to be much cheaper than the available atrix lapdocks.

Just got mine working ^_^

I'm glad I could be of help.
Good luck!

does anyone know the answer to this?

I have a tip. When you post a URL, it's either "http://" or "www.". It's never both.
nerd74731 year ago
very cool you should make it to where the pi is protected so you can carry it around
I'll be doing something like this but with one of those Android smart TV sticks instead. I've learned that some of the common sticks like the Rikomagic models will fit in place of the phone dock connector once the plastic is removed from inside the flap. this allows for better stability and the flap can stay closed for a more streamlined look. I may run Linux once I get it going.

I may make an Instructable for doing this. After all, those sticks are now quite powerful and still affordable. For $90 I can get a brand new model that has Wifi, Bluetooth, micro SD slot, 1.8GHz 4 core Cortex A9 CPU, 4 core Mali GPU at 533MHz, 2GB DDR3 RAM, Android 4.2.2, and other stuff. Should be quite speedy.

Some holes drilled in the docking flap where the PC guts lie to aid in cooling and I have a cheap Android laptop for my stuff.

Excellent. If I can inspire people such as yourself to do similar,
or better things than I did, then I consider my Instructable to
be a success. And, I strongly encourage you to document your project with an Instructable.

Wasn't that. Finally just plugged a mini USB cable into a USB wall outlet and that made it work

I am having trouble with getting the keyboard and trackpad to work. Suggestions for things to try?
thegrendel (author)  mringman1 year ago
Try a different USB adapter/cable.

See if the little light in the upper left hand corner of the trackpad
is on. If not, try tapping it to switch on trackpad and keyboard.

I have done this, as many have and it is very particular about the HDMI cable, you may want to boost the HDMI current in the config file if you have an issue with no video.

If you have a keyboard race condition it is most likely a power issue. Given the will use about 700 to 1000ma, your cable should be short with a high current. You can by a Y cable (blackberrry) to put power into two ports (more current mico usb and standard).


The HDMI to micro HDMI anc be finicky seat it properly. Power to the USB only happens if a "good" connection is detected. One hacker opened up the box and exposed the HDMI connector soldering his own cable.

The origional (not me) post was on Raspberry Pi Forum:

A valid point. The HDMI connection is absolutely critical.

This isnt really an original design, Adafruit had done this design first........ Originality please?
thegrendel (author)  kokid991 year ago
I'm not claiming originality, whatever that means.
And in the last step of this Instructable I have a partial list of URLs
of others who have done this project before me. I will note, though,
that I haven't been able to find another Instructable dealing with
this particular project.

And Adafruit was not the first to do it, either.
The Adafruit method of hooking up involves soldering,
and in any case, the methodology is confined to a youtube video.
I've done it in more detail, and with close-up pics.

Kid, there's nothing at all wrong with multiple persons submitting
the same or a similar project. It give you alternate ways of doing it
and alternate points of view on technique.
