iFixit licenses manuals under Creative Commons

Yesterday, iFixit.com announced that they are releasing all of their manuals under the Creative Commons Attribution-Noncommercial-Share Alike license. The site has long been an abundant source of tear-down photos for hardware and has been gaining momentum as the go-to source for Apple hardware repair information. With the move to Creative Commons, the gates are open to distribute and improve upon the site’s content. There are even plans in the works to host user-submitted improvements (something akin to a wiki?) to the guides but there are not yet any details. The news also includes mention of forthcoming support for translated guides around the end of 2010.

The Hackaday crowd would rather fix things than throw them away. As iFixit moves past Apple products to a wider range of repair manuals and starts working collaboratively with users, we hope to see an explosion of detailed tips, tricks, and guides to keep our stuff working better, longer.

Juicero: A Lesson On When To Engineer Less

Ben Einstein, a product designer and founder at Bolt, a hardware-based VC, recently got his hands on a Juicero press. This desktop juice press that only works with proprietary pouches filled with chopped fruits and vegetables is currently bandied in the tech press as evidence Silicon Valley has gone mad, there is no future in building hardware, and the Internet of Things is a pox on civilization. Hey, at least they got the last one right.

This iFixit-style tear down digs into the Juicero mixer in all its gory details. It’s beautiful, it’s a marvel of technology, and given the engineering that went into this machine, it was doomed to fail. Not because it didn’t accomplish the task at hand, but because it does so with a level of engineering overkill that’s delightful to look at but devastating to the production cost.

Fix-a-Brick: Fighting the Nexus 5X Bootloop

Oh Nexus 5X, how could you? I found my beloved device was holding my files hostage having succumbed to the dreaded bootloop. But hey, we’re hackers, right? I’ve got this.

It was a long, quiet Friday afternoon when I noticed my Nexus 5X was asking to install yet another update. Usually I leave these things for a few days before eventually giving in, but at some point I must have accidentally clicked to accept the update. Later that day I found my phone mid-way through the update and figured I’d just wait it out. No dice — an hour later, my phone was off. Powering up led to it repeatedly falling back to the “Google” screen; the dreaded bootloop.

Stages of Grief

I kept my phone on me for the rest of the night’s jubilant activities, playing with it from time to time, but alas, nothing would make it budge. The problem was, my Nexus still had a full day’s video shoot locked away on its internal flash that I needed rather badly. I had to fix the phone, at least long enough to recover my files. This is the story of my attempt to debrick my Nexus 5X.

Bringing The Best Laptop Ever Made Back To Life

Eight or nine years ago, Apple was on top of the world. The iPhone just revolutionized phones, Apple was still making computers, and these computers were actually repairable. Of the late 2008/early 2009 MacBook Pro, iFixit said, “What an incredible machine. We are very impressed by the ease with which the new MacBook Pro came apart. This machine should be a joy to work on”. Apple has come a long way since then.

macbook-reflow-shield[DocDawning] has a bit of a Mac hoarding problem, and frequently pays $20 for broken laptops of this vintage. Most of the time, the fix is simple: the RAM needs to be reseated, or something like that. Rarely, he comes across a machine that isn’t fixed so easily. The solution, in this case, is a deep dive into heat guns and thermal management. How do you bring a laptop back from the dead? [Dawning] shows you how.

Like the old XBox towel hack, the first thing to look for in dead electronics is broken solder balls. Of course, actually looking at broken solder balls is pretty hard, so you might as well just get out a heat gun and go at it. That’s exactly what [Dawning] did. With the clever application of an aluminum takeout tray to direct the heat flow, he blasted each of these chips with enough heat to hopefully melt all the balls.

With that, a working MacBook Pro was just a liberal application of thermal paste away. From $20 at the scrap heap to a working computer, [Dawning] did it. He successfully resuscitated a broken computer.

Microsoft Surface Book Teardown Reveals Muscle Wire Mechanism

It’s hard to resist the temptation to tear apart a shiny new gadget, but fortunately, iFixIt often does it for us. This helps to keep our credit cards safe, and reveal the inner workings of new stuff. That is definitely the case with the Microsoft Surface Book teardown that they have just published. Apart from revealing that it is pretty much impossible to repair yourself, the teardown reveals the mechanism for the innovative hinge and lock mechanism. The lock that keeps the tablet part in place when in laptop mode is held in place by a spring, with the mechanism being unlocked by a piece of muscle wire.

We are no strangers to muscle wire (AKA Nitinol wire or Shape Metal Alloy, as it is sometimes called) here: we have posted on its use in making strange robots, robotic worms and walls that breathe. Whatever you call it, it is fun stuff. It is normally a flexible wire, but when you apply a voltage, it heats up and contracts, much like the muscles in your body. Remove the voltage, and the wire cools and reverts to its former shape. In the Microsoft Surface Book, a single loop of this wire is used to retract the lock mechanism, releasing the tablet part.

Unfortunately, the teardown doesn’t go into much detail on how the impressive hinge of the Surface Book works. We would like to see more detail on how Microsoft engineered this into the small space that it occupies. The Verge offered some details in a post at launch, but not much in the way of specifics beyond calling it an “articulated hinge”.

UPDATE: This post was edited to clarify the way that muscle wire works. 11/4/15.

The Key to Modular Smartphones

Cellphone startup Fairphone is now taking pre-orders for their modular smartphone, which is expected to start shipping in December of this year. Although I’m much more familiar with Google’s project Ara, this is the first modular concept to make it to market. It does lead me to a few questions though: is this actually a modular smartphone, and how widely will modular concepts be adopted?

The Ubiquitous Atari Punk Console

The Atari Punk Console (APC) is a dual 555 (or single 556) based synth. Designed by the famous (and somewhat infamous) Forrest Mims in 1980 and originally simply named “Sound Synthesizer”, the circuit gained it’s more recent popularity when re-dubbed the “Atari Punk Console” by Kaustic Machines. The circuit however doesn’t bear much relation to the Atari 2600 which didn’t contain a 555 timer chip. However we assume the 2600 produced a similarly glitchy square wave audio output.

a2The circuits operation is easy to grasp and uses only 9 components. This ease of design and construction has allowed builders to focus more on the aesthetics of its construction, hacking it into interesting, and often unlikely enclosures and systems. One such hack is the “Atari Punk Bucket” (shown here) where the APC along with a simple amp was hacked into an old rusted bucket. The APC was built up on strip-board along with a simple amp and reclaimed speakers. [Farmer glitch] has used this as a prop in live sets and it both looks and sounds awesome.
