LapPi project transforms a Raspberry Pi into a laptop (in a briefcase)

The Raspberry Pi is a mini PC with a $35 price tag, a 700 MHz ARM11 processor, up to 512MB of RAM, and Ethernet, USB, and HDMI ports. It’s about the size of a pack of cards, and we’ve seen people cram the entire PC into a keyboard, a camera grip, and other tight spaces.

You can even transform the little desktop PC into a laptop with the aid of a cheap Motorola Lapdock. Or you could just build your own laptop from a briefcase, display, keyboard, and a few other components.

That’s the approach Instructables member SilverJimmy decided to take for his LapPi project.


The end result is a pretty functional mobile PC, featuring WiFi, Bluetooth, a keyboard, touchpad, display, and batteries. SilverJimmy also threw in GPS, a mic, and stereo speakers for good measure.

The whole thing runs on a 10-pack of rechargeable AA batteries, although it can also use 8 alkaline AA batteries instead.

Sure, when you add up the cost of all the parts you could probably buy a cheap netbook for less money. But where’s the fun in that?

    I like the design this has. I’ve recently put some research effort into parts selection for a solar Pi and have posted them on the elinux page for the Raspberry Pi, laptop subsection: It includes other battery options (NiMh are good in the ubiquitous sense, but LiFePO4 could be a little more ubiquitous too).

    the pi now has 1gig of ram for the same price..

      Nope. It used to have 256MB. They doubled that and it now has 512MB for the same price. They haven’t moved to 1GB just yet…

      yeah…no…the $35 has 512…the $25 has 256

    Could have fit a larger keyboard and screen in that case!

      probably a user preference, but I too would opt for a larger one.
