Pinkpad, A DIY Laptop You Must Print In Pink

April 1, 2024 by 19 Comments

Looking to build a laptop all on your own? Check out the Pinkpad, a DIY laptop project that as if appeared out of nowhere, gives you a based on an off-the-shelf Dell motherboard. This build projects an aura of unabashed competence – the website brings you to a different universe, the documentation is as curt as it is extensive, and the build evidently works.

With a Thinkpad x61 keyboard, a reasonably modern (Dell Vostro 5481, Ryzen possible) motherboard embeddable inside, and a 10″ 1024×768 screen, this ~11″ laptop packs a certain kind of punch for what’s a build-it-yourself project. Most of the value of this design is in the 3D files – which were done in Google SketchUp, and the laptop is small enough that you could print its shell reasonably quickly. Not that you should follow the parts list religiously – the screen in particular might just warrant reconsideration in your eyes. On the other hand, we wish you all the luck on your SketchUp journey if you want to modify the shell. It also isn’t lost on us that the parts list doesn’t list a battery in it.

This is an impressive project to see open-sourced, and we hope it can inspire some hackers in the custom laptop building cohort. One prominent flaw of consumer-facing technology is that you can’t always get your devices in pink, and printing your laptop’s chassis yourself is a surefire way to combat this. If this laptop’s form-factor is too commonplace for you, we’ve seen no shortage of custom laptops grace our pages, from miniature ones to CRT luggable beasts, and click on the tags below if you’d like to see more!

OSHW Framework Laptop Expansion Hides Dongles

April 1, 2024 by 16 Comments

If you’ve got a wireless keyboard or mouse, you’ve probably got a receiver dongle of some sort tucked away in one of your machine’s USB ports. While modern technology has allowed manufacturers to shrink them down to the point that they’re barely larger than the USB connector itself, they still stick out enough to occasionally get caught on things. Plus, let’s be honest, they’re kind of ugly.

For owners of the Framework laptop, there’s now a solution: the DongleHider+ by [LeoDJ]. This clever open source hardware project is designed to bring these little receivers, such as the Logitech Unifying Dongle, into one of the Framework’s Expansion bays. The custom PCB is designed with a large notch taken out to fit the dongle’s PCB, all you need to do is solder it in with four pieces of stiff wire.

Deep Dive Into A Prison Laptop

February 26, 2024 by 30 Comments

The phenomenon of prison electronics is by now relatively well-documented, with striking transparent radios, televisions, and kin easy to recognize. Yet what about prison laptops? As it turns out, these are a thing as well, and [Zephray Wenting] got one from eBay to investigate, as documented over at Twitter (ThreadReader single page). Much like their audiovisual brethren, these laptops lack basic features in the name of prison security, which in the case of this laptop means for example no USB ports. Even the spacebar stabilizer rod is missing. Weaponized keyboards are apparently a thing in corrections facilities.

Called the Justice Tech Solutions Securebook 5, it has been superseded by the Securebook 6. Inside this earlier unit, you’ll find an Intel N3450 with 4 GB LPDDR3, with SATA for storage and a special dock connector. Some laptops come with WiFi hardware installed, others are unpopulated. It appears that these Securebooks by default have a BIOS password that cannot be erased, even by removing it from the NVRAM (‘CMOS’), as it’ll return on the next boot due to an automatic BIOS reset. This was temporarily bypassed through a hacky external SPI Flash adapter, but the reward for all this trouble was a BIOS setup screen with just the ‘Security’ tab.

It’s now been sleuthed out that the default password is N%(dU32p as reported by Hackaday’s own [Adam Fabio] on Twitter. It turns out the password was available on a (now private) YouTube video. [Techknight] on Twitter has delved into EFI BIOS hacking. He has an alternate BIOS image that does provide access to the full BIOS setup utility. With BIOS access not being necessary to boot the system, the question that [Zephray] went ahead with was how to boot it into an OS since the original HDD or SSD had been removed prior to being sold. The bad news here is that it turned out that the system has a HDD whitelist (which [Sark] found a way to bypass). The good news is that someone has probed the system before, with the storage device being reported as ‘China SATA3 240GB SSD’.

Rather than mess with this, it was attempted to boot from USB, by tapping into the USB lines for the touchpad, which turned out to allow booting into a live image of Ubuntu without fuss. As an ongoing project, it’ll be interesting to see what more functionality can be wrung out of this piece of prison kit, all hopefully from the right side of the prison bars.

Retro-Styled Rasti Laptop Packs Framework Mobo

February 2, 2024 by 7 Comments

Today, every laptop pretty much looks like every other laptop. Sure you might run into a few different colors and screen sizes out there, but on the whole, all the manufacturers have pretty much agreed on the basic shape and nobody is looking to rock the boat with something different.

Ah, but it wasn’t always so. Before the form factor we all recognize today took over, there were all sorts of interesting variations on the basic portable computer concept. For the Rasti, creator [Penk Chen] definitely took some inspiration from the iconic (and largely unobtanium) GRiD Compass of NASA and Aliens fame. But while its 3D printed case might look like a product of the early 1980s, on the inside, it features a Framework Laptop 13 mainboard using an 11th gen Intel CPU.

In addition to the widescreen 10.4 inch (1600 x 720) QLED display from Waveshare, the Rasti also includes a custom mechanical keyboard that’s actually been spun off into its own project. So even if you can’t swing building the whole Rasti, you could still find yourself tapping away on its vintage-styled input device.

Somewhat unsurprisingly, this isn’t the first time we’ve seen somebody 3D print a computer inspired by the GRiD Compass. The GRIZ Sextant we covered back in 2021 was another triumph that would be the envy of any hacker meetup.

Bringing An IBM Butterfly Laptop Back From The Dead

January 28, 2024 by 8 Comments

Among all the laptops produced over the last few decades, there is one which rises above the rest and which has retained an appeal long after its meager computing resources became obsolete. It’s the IBM 701c, the famous “Butterfly” laptop, whose fold-out keyboard still gives it star  quality, and [John Graham-Cumming] has documented the restoration of one from the tattered remains of two scrap examples.

The two laptops in question were someone else’s never-started project, and were in a sorry state. The flexible cables were in poor condition, and the 1990s Ni-MH batteries had leaked and damaged both circuits and case. We were unaware that NiMH leakage could damage plastic, but the parts of these machines were significantly damaged.

One had a working mainboard, the other a working modem card. One keyboard was in pretty bad shape, the other was complete. Of the pair there was a double super twisted nematic (DSTN) display and a more contemporary thin film transistor (TFT) panel. Be thankful if you have never had to use a DSTN laptop, as they were truly awful. From this pile of parts a working machine could be made, and with a new CMOS battery, that cable repair, and a repaint, he was ready. Or at least, as he says, ready for 1995.

This isn’t the first 701c restoration we’ve seen, and within reason, it’s even possible to give them a retro processor upgrade.

Laptop Memory Upgradable Again

January 14, 2024 by 38 Comments

For some computing components, the bottleneck to improved speed and performance hasn’t been power consumption or clock speed but physical space. But a new memory standard may provide all of the power and space-saving benefits of soldered memory modules without losing any upgradability.

The standard is called compression attached memory modules (CAMM) and provides a way for small form factor computers to have upgradable memory without needing dual in-line memory module (DIMM) slots. Unlike DIMM, though, CAMM modules allow for modern high-speed low-power memory to be used and can take advantage of dual-channel properties even if only one memory module is installed. CAMM modules are held in place with small screws, similar to modern M.2 drives, and don’t have the massive footprint of a DIMM slot. This allows laptop manufacturers to save nearly as much space as having soldered memory.

While this won’t solve the problem of computer manufacturers offering only soldered memory as a cash-grab, hopefully, some take the new standard under their wing for those of us who value the upgradability of our hardware. There are of course some problems with newer standards, but right now it seems like the only other viable option is soldered modules or slower, heavier computers. Some may argue that these soldered-on modules can be upgraded in theory, but not without considerable effort.

The Laptop Every British Kid Would Have Wanted For Christmas 1983

December 17, 2023 by 12 Comments

How can we convey to a world in which a 64-bit laptop can be a near-throwaway item, just how amazing a miniature laptop version of the 1980s Sinclair ZX Spectrum could have been? perhaps we don’t need to, because here in 2023 there’s a real one for all middle-aged geeks who had the original to drool over.

8-bit home computers were super-exciting for the kids of the day, but they were in no way portable and relied on a TV, frequently the family model in the living room. It’s safe to say that a portable version of one of those home computers, not in an Osborne-style luggable case but in a clamshell palmtop, would have been mind-blowing, so four decades later we’re fascinated by [Airrr17]’s portable Sinclair ZX Spectrum.

At its heart is a dev board using one of the STM32F4 series microcontrollers, and running the Spectrum as an emulator. Alongside that is an LCD, and perhaps what is physically the best part of this, a Spectrum keyboard complete with BASIC keyword decals, made with large-button tactile switches that have we think, printed paper on top. Add in a small lithium-polymer cell and associated electronics in a cute little palmtop case, and it’s about as good a portable Sinclair as we could have imagined. All the details can be found in a GitHub repository, and as if that weren’t enough there’s an assembly video we’ve placed below the break.
