Wooden Laptop Enclosure: New Life For Old Thinkpad

June 28, 2017 by Inderpreet Singh 21 Comments

Technology is designed to serve us and make our lives better. When a device gets outdated, it is either disposed of or is buried in a pile of junk never to be seen again. However, some individuals tend to develop a certain respect for their mechanical servants and make an effort to preserve them long after they have become redundant.

My relationship with my first laptop is a shining example of how to hold onto beloved hardware way too long. I converted that laptop into a desktop with a number of serious modifications which helped me learn about woodworking along the way. Maybe it’s more pragmatic to just buy new equipment. But you spend so much time each day using your devices. It is incredibly satisfying to have a personal connection that comes from pouring your own craftsmanship into them.

Why the Effort?

The laptop in question is an IBM R60 which I lugged around during the first three years after I graduated. It was my companion during some tough times and naturally, I developed a certain attachment to it. With time its peripherals failed including the keyboard which housed the power switch and it was decided that the cost of repair would outweigh its usefulness.

Then came the faithful day when I was inspired to make something with the scrap wood that had accumulated in my workshop. This would be my second woodworking project ever and I did not have the professional heavy machinery advertised in most YouTube videos. Yet I had two targets in mind with this project.

Make the R60 useful again.
Learn about woodworking for creating enclosures for future projects.

Armed with mostly hand tools, a drill and a grinder that was fitted with a saw blade, I started with the IBM R60 to all-in-one PC mod. Following is a log of things I did and those I regret not doing a.k.a. lessons learned. Read on.

HP Laptops Turn Up Keylogger Where You Wouldn’t Expect It

May 12, 2017 by Lewin Day 58 Comments

Keyloggers are nasty little things that have the potential to steal the credit card numbers of you and everyone you care about. Usernames and passwords can be easily stolen this way, so they’re a useful tool for the black hats out there. One would generally expect to find a keylogger in a dodgy movie torrent or perhaps a keygen for pirated software, but this week a keylogger was found in an audio driver for an HP laptop.

The logger was found by Swiss security researchers modzero. The Conexant HD Audio Driver Package version 1.0.0.46 and earlier apparently logs keystrokes in order to monitor things like the laptop’s volume up and down keys. The real killer here is that it feels the need to log all keystrokes detected to a readily accessible file, for reasons we can’t possibly fathom. It’s a huge security risk, but it doesn’t stop there – the driver also exposes the keystrokes through an API as well, creating an even wider attack surface for malicious actors. One can in principle access the keystroke log remotely.

There’s no word from the company yet, but we really want to know – why save the keystrokes to a file at all? Code left over from debugging, perhaps? Speculate in the comments.

Hands On With The Pinebook

April 28, 2017 by Alasdair Allan 101 Comments

The Pine A64 was a 64-bit Quad-Core Single Board Computer which was kickstarted at the tail end of 2015 for delivery in the middle of 2016. Costing just $15, and hailed as a “Raspberry Pi killer,” the board raised $1.7 million from 36,000 backers. It shipped to its backers to almost universally poor reviews.

Now they’re back, this time with a laptop—a 11.6-inch model for $89, or a 14-inch model for $99. Both are powered by the same 64-bit Quad-Core ARM Cortex A53 as the original Pine A64 board, but at least Pine are doing a much better job this time around of managing user expectations.

Sandwich Together A Raspberry Pi Laptop

March 29, 2017 by Jenny List 26 Comments

Ever since the Raspberry Pi was released to an eager public just over five years ago there is one project that seems to have been tackled more frequently than any other using the small computer from Cambridge: that of making a laptop with Pi for brains. Perhaps you feel you have had your fill of Pi laptops both good and bad, but it’s still a project that can bring up some surprises.

Does [Eben] carry a silver marker with him, laptops for the signing of? — Does [Eben] carry a silver marker with him at all times, laptops for the signing of?

[Archie Roques] is a young maker from Norwich, UK, and at the Raspberry Pi birthday party in early March he had rather an unusual laptop. He’d done the usual thing of mating the official Pi screen, a bluetooth keyboard/touchpad, Pi, and battery, but as always it’s the detail that matters. His case is a carefully designed sandwich of laser-cut plastic that somehow manages the impossible task of containing all the laptop internals while not being too bulky.

For power he at first used a 4 AH LiPo cell from a dead tablet with a Pimoroni LiPo power board, but since he hit problems with the Pimoroni board supplying both screen and Pi he’s switched to an off-the-shelf power bank. Unusually this laptop also has built-in audio, using another Pimoroni product, their speaker pHAT.

Where this laptop has a flaw though is in the display hinges. He has plans for a beautifully made 3D printed hinge, but for now he’s using a piece of tape, which though functional does not add to the aesthetic. When we saw it in Cambridge the keyboard was fitting more snugly than it does in the photos on his write-up, so perhaps he’s fixed some of its issues. Despite the in-progress hinge it’s a very usable little Pi laptop, and though (Hint, [Archie]!) he hasn’t yet published the design files for it, we’re sure when he does we’ll see other people building the same machine. They won’t be quite as exclusive as [Archie]’s model though, while he was in Cambridge he managed to get it signed by [Eben Upton], founder of the Raspberry Pi Foundation and judge for the 2017 Hackaday Prize.

We recently showed you a Pi laptop build in a cigar box that was useful in its detailing of the various modules required, but in the past we’ve shown you another one using the official touch screen, a lovely one in the style of a Psion palmtop, and vertically bulky yet small-footprint one, and another that keeps its presence hidden.

A tip of the hat to Norwich Hackspace.

Cigar Box Opens To Raspberry Pi Laptop

March 21, 2017 by Jenny List 25 Comments

If you were to go back to the middle years of the twentieth century and talk to electronic constructors, you would find a significant number had a cigar box radio among their projects. Cigar boxes were fairly robust, readily available, and could easily accommodate the parts required to make a crystal set or a simple one-tube regenerative receiver. These days there isn’t much attraction to a simple AM radio though, so while they can still be fun to build, the cigar box radio only occupies a niche in vintage radio circles.

Cigar boxes, however, remain. [Mike] found a very nice antique cigar box, and made something unexpected, he put a Raspberry Pi in it and made something close to a laptop. Into the lid goes an LCD screen secured with wooden blocks, while in the body of the box goes the LCD controller, Pi 3, and battery charger and PSU modules. There are two sets of cells, one each for screen and Pi.

We like the idea and we like his write-up for its clear run-down of the modules required even though it’s mostly a plug-together build. We described it as “Something close to a laptop” because it has one glaring omission. He’s using an external keyboard rather than having incorporated one within the case. We think there looks as though there is plenty of room for one, so perhaps he’ll return to the project and upgrade it in that way. For reminding us that cigar boxes can make excellent laptop cases though, we’re thankful.

We’ve featured numbers of Raspberry Pi laptops over the years since the little computer’s launch. Just a small selection are this one using the official touch screen, a rather beautiful one in the style of a Psion palmtop, and one that is rather chunky but has a small footprint. Meanwhile in cigar boxes, we’ve brought you an excellent little 555 organ.

An Ugly But Functional Pi Laptop

March 11, 2017 by Dan Maloney 17 Comments

It’s got a face only its mother could love. Or a Hackaday writer, since this ugly e-waste laptop proudly sports a Jolly Wrencher on its back.

All joking aside, this is a great example of doing what you can with what you’ve got. [starhawk] is limited on funds, and a regular laptop is beyond his means. But being light in the wallet is no reason to go without when you can scrounge parts from friends and family. The base of the laptop is a mini USB keyboard, with the top formed mainly by a 7″ HDMI panel. The back of the display is adorned with a Raspberry Pi 3, a USB hub, a little sound dongle, and the aforementioned Jolly Wrencher. The whole thing is powered by a cast-off power supply brick — no exploding batteries to worry about!

Other Pi-based laptops we’ve covered may be sleeker, but we’ve got to admit that [starhawk]’s keyboard is probably the better choice for working on the next great American novel. And a Linux laptop for next to nothing? That’s a win in our book.

Raspberry Pi Laptop Uses The Official Touchscreen

February 12, 2017 by Jenny List 20 Comments

We’ve seen a variety of home-made laptops using the Raspberry Pi and other single board computers over the years. Usually, they combine off-the-shelf USB keyboards and trackpads with HDMI monitor panels, and cases made from layered laser cut sheet, or 3D printed plastic.

[Surferboy]’s Raspberry Pi laptop is the latest effort to come before us, and its claim to fame is the use of the official Raspberry Pi 7″ touchscreen as a display. Full instructions and 3D printer files are available on Thingiverse so you can have a go at replicating it if a portable Pi is your thing.

He’s taken the bold step of not attempting to place all the Pi’s interfaces next to the outside of the case. Instead, he’s desoldered the Ethernet and USB ports. The USB connections were wired directly to the keyboard, display, and a couple of external ports on the right-hand side of his case. This leaves the finished laptop with no Ethernet. However, losing ethernet is a worthy tradeoff for the thinner package.

[Surferboy] also brought the GPIO header to a female socket on the rear of the unit. It’s unclear exactly what battery he uses except for a reference to the battery from his keyboard. Since a keyboard battery will be too small for Pi and display we are guessing a larger pack will be necessary.

Though the Ethernet port and battery issue would probably be a dealbreaker here this has the makings of a useful and compact laptop, it will be interesting to see if it is picked up and refined by the community.

Quite a few early Pi laptops used the Motorola Lapdock, a mobile-phone-into-netbook peripheral. Some others we’ve featured have been a bit chunky, but sometimes they can be objects of beauty.
