Open Laptop Soon To Be Open For Business

January 21, 2020 by Kerry Scharfglass 74 Comments

How better to work on Open Source projects than to use a Libre computing device? But that’s a hard goal to accomplish. If you’re using a desktop computer, Libre software is easily achievable, though keeping your entire software stack free of closed source binary blobs might require a little extra work. But if you want a laptop, your options are few indeed. Lucky for us, there may be another device in the mix soon, because [Lukas Hartmann] has just about finalized the MNT Reform.

Since we started eagerly watching the Reform a couple years ago the hardware world has kept turning, and the Reform has improved accordingly. The i.MX6 series CPU is looking a little peaky now that it’s approaching end of life, and the device has switched to a considerably more capable – but no less free – i.MX8M paired with 4 GB of DDR4 on a SODIMM-shaped System-On-Module. This particular SOM is notable because the manufacturer freely provides the module schematics, making it easy to upgrade or replace in the future. The screen has been bumped up to a 12.5″ 1080p panel and steps have been taken to make sure it can be driven without blobs in the graphics pipeline.

If you’re worried that the chassis of the laptop may have been left to wither while the goodies inside got all the attention, there’s no reason for concern. Both have seen substantial improvement. The keyboard now uses the Kailh Choc ultra low profile mechanical switches for great feel in a small package, while the body itself is milled out of aluminum in five pieces. It’s printable as well, if you want to go that route. All in all, the Reform represents a heroic amount of work and we’re extremely impressed with how far the design has come.

Of course if any of the above piqued your interest full electrical, mechanical and software sources (spread across a few repos) are available for your perusal; follow the links in the blog post for pointers to follow. We’re thrilled to see how production ready the Reform is looking and can’t wait to hear user reports as they make their way into to the wild!

Replacing A Non-Replacable Laptop Keyboard

December 23, 2019 by Lewin Day 29 Comments

Spilling a drink on a laptop is a terrifying experience. If you’re lucky you’ll ruin just a keyboard, and if not, your entire machine could go up in smoke. Assuming you’ve just suffered the latter, you can still be out of luck, as many laptops come with fancy integrated keyboards that are not designed to be removable. It’s not always the case however, as this ingenious hack from [InsideMyLaptop] bears out.

The hack begins with removing the top case assembly from a HP Pavilion laptop. The keyboard is riveted into the top plate assembly, along with the trackpad, which would normally necessitate their replacement as a total unit. However, if properly armed with a soldering iron, these plastic rivets can be melted to allow the backing plate and keyboard to be removed. A replacement part can then be sourced, and the remaining rivet stubs can be remelted to hold the new part in place.

It’s a simple hack, but one that goes to show one shouldn’t always take “No User Servicable Parts Inside” as an answer. We’ve seen other useful work from [InsideMyLaptop] before – like this power jack repair way back in 2011.

Razer Laptop Gets A Sneaky Fan Mod

November 5, 2019 by Lewin Day 10 Comments

Some people love fan noise, using it to help get to sleep or just create some ambience in a room. Others hate it, like [Dimitris], and will take severe measures to eliminate it where possible. When his Razer Blade laptop was incessantly whirring away, it was time to get to work.

The Razer laptop uses a controller that outputs a variable duty cycle signal to control fan speed. Unfortunately, the fans never fully switch off, even when the laptop is cold, leading to frustrating excessive noise. [Dimitris] implemented an ATtiny85 to intercept this signal, giving him full control over the fans. Two modes are implemented, one which keeps the fans off when the duty cycle is at its minimum, and the other that attempts to keep the fans at a minimum speed wherever possible.

While modifying the critical cooling system of a high-performance laptop is a risky business, it’s a decent price to pay for some peace and quiet. We’ve seen quite the opposite to this mod, too – like this Xbox 360 outfitted with additional cooling.

Dual Screen Laptop Is A Slick DIY Build

September 28, 2019 by Lewin Day 32 Comments

Laptops are great for portable productivity, but ergonomically they can leave something to be desired. They tend to force the user to look down, creating neck strain over extended periods. Rather than invest in expensive massages, [DIY Perks] decided what he really wanted was a dual screen laptop. So he built one! (Video embedded below.)

The build stats with a replacement laptop screen sourced from eBay, a nice full-HD IPS unit with a matching Embedded DisplayPort driver to enable the screen to be driven with the laptop’s existing HDMI port. To power the display, a USB-C Power Delivery board is used, in combination with a high-quality USB-PD compliant battery pack. This provides the 12 V required to run the screen.

To integrate the screen into the laptop, a set of 3D-printed hinges are used to create a folding mechanism, along with a brushed aluminium backing plate. Finished with a set of 3D-printed bezels, the final result is quite attractive from the front, looking almost stock at a glance.

It’s a build that may prove enticing to serious laptop professionals, particularly those that are willing to trade-off productivity against a little added bulk. We’ve seen other great work from [DIY Perks] before too, like these versatile LED panel lights. Video after the break.

Modern Linux Runs On Ancient Toshiba

August 23, 2019 by Bryan Cockfield 65 Comments

While Microsoft no longer supports those of its operating systems that were in heavy use into the early 2000s, support for old hardware is not typically something that you will have to worry about if you run Linux on your machines. Sure, there will be driver issues from time to time, and you might have to do some things by hand, but if you’re using legacy hardware you’ll want a Linux distribution of some sort. Especially if you’re running it on one of the first laptops to ever feature a Pentium processor of any kind.

This is a Toshiba T4900CT which [MingcongBai] has been able to spruce up by installing a simplified version of the AOSC OS Linux distribution. The distribution is known for its simplified user interface, and this particular one runs a “Retro” command-line-only version. Upon startup (which takes over two minutes), the user can view the hardware and software specs: Linux kernel 4.19.67 (released within the past year) on a 75 MHz Intel processor.

Getting old equipment to work, even if the software is available, is a challenge and this one stands out for the historical noteworthiness of the laptop. We didn’t see it connect to the Internet, but if it ever does we still keep Retro Hackaday up specifically for situations like this.

A Real All-In-One Printer Should Have A Computer In It, Too

August 16, 2019 by Dan Maloney 14 Comments

With printers generally being cheaper to replace than re-ink, there are plenty of cast-offs around to play with. They’re a great source for parts, but they’re also tempting targets for repurposing for entirely new uses. Sure, you could make a printer into a planter, but slightly more useful is this computer built into a printer that still prints.

This build is [Mason Stooksbury]’s earlier and admittedly useless laptop-in-a-printer build, which we covered a few months back. It’s easy to see where he got his inspiration, since the donor printer’s flip-up lid is a natural for mounting a display, and the capacious, glass-topped scanner bed made a great place to show off the hybrid machine’s guts. But having a printer that doesn’t print didn’t sit well with [Mason], so Comprinter II was born. This one follows the same basic approach, with a Toshiba Netbook stuffed into an H-P ENVY all-in-one. The laptop’s screen was liberated and installed in the printer’s lid, the motherboard went into the scanner bay along with a fair number of LEDs. This killed the scanner but left the printer operational, after relocating a power brick that was causing a paper jam error.

[Mason]’s Comprinter II might not be the next must-have item, but it certainly outranks the original Comprinter on the utility spectrum. Uselessness has a charm of its own, though; from a 3D-printed rotary dial number pad to a useless book scanner, keep the pointless projects coming, please.

Preserving Precious Laptop Stickers

July 12, 2019 by Brian Benchoff 75 Comments

Stickers belong on laptops. That’s not just because all developers are issued a 2015 MacBook Pro at birth to zealously hold and cherish for the rest of their careers, and the vast uniformity of laptop models in the workplace makes each individual’s laptop indistinguishable from anyone else’s. No, stickers belong on laptops because that ‘RUN GCC’ sticker is just so good. But how do you keep a laptop stickered up while not hurting the resale value or worrying about sticky residue left behind? That’s the question [Graham] answered, and the answer may surprise you.

The problem is such: there mus be a way to apply stickers to a MacBook that is invisible, removable, and leaves no trace after being removed, even after years of enjoying a bestickerd’ laptop. The first thought turned to old-style screen protectors for a phone, but this had problems: they’re glossy, and sourcing a large sheet of screen protectors proved difficult.

After some research, it turned out there was a market with similar requirements: car wraps. Yes, you can wrap your car in vinyl that’s any color you want, including whatever Apple is calling their plain aluminum finish these days. As far as a protector for an aluminum MacBook, it looks good: it doesn’t leave any residue behind, it’s strong enough to survive on a car, so it’s probably good enough for a laptop on a desk, and it’s easy to apply.

With some stickers applied to this larger sticker, everything looked good and lived up to a few months of abuse. Then came the real test: could this MacBook wrap be removed with all the other stickers intact? Yes, and you can frame the result. While this is only a test of the aluminum-colored MacBook, vehicle wraps come in nearly every color imaginable. There is apparently a vinyl that looks like Space Gray, and if you want Thinkpad Black, you can get that wrap, too.
