The Ultimate IPhone Upgrade

April 13, 2018 by Bryan Cockfield 48 Comments

While Apple products have their upsides, the major downside with them is their closed environment. Most of the products are difficult to upgrade, to say the least, and this is especially true with the iPhone. While some Android devices still have removable storage and replaceable batteries, this has never been an option for any of Apple’s phones. But that doesn’t mean that upgrading the memory inside the phone is completely impossible.

[Scotty] from [Strange Parts] is no stranger to the iPhone, and had heard that there are some shops that can remove the storage chip in the iPhone and replace it with a larger one so he set out on a journey to try this himself. The first step was to program the new chip, since they must have software on them before they’re put in the phone. The chip programmer ironically doesn’t have support for Mac, so [Scotty] had to go to the store to buy a Windows computer first before he could get the chip programmer working right.

After that hurdle, [Scotty] found a bunch of old logic boards from iPhones to perfect his desoldering and resoldering skills. Since this isn’t through-hole technology a lot of practice was needed to desolder the chip from the logic board without damaging any of the other components, then re-ball the solder on the logic board, and then re-soldering the new larger storage chip to the logic board. After some hiccups and a lot of time practicing, [Scotty] finally had an iPhone that he upgraded from 16 GB to 128 GB.

[Scotty] knows his way around the iPhone and has some other videos about other modifications he’s made to his personal phone. His videos are very informative, in-depth, and professionally done so they’re worth a watch even if you don’t plan on trying this upgrade yourself. Not all upgrades to Apple products are difficult and expensive, though. There is one that costs only a dollar.

We sat down with him after his talk at the Hackaday Superconference last November, and we have to say that he made us think more than twice about tackling the tiny computer that lies hidden inside a cell phone. Check out his talk if you haven’t yet.

Scotty Allen Visits Strange Parts, Builds An IPhone

March 27, 2018 by Elliot Williams 19 Comments

Scotty Allen has a YouTube blog called Strange Parts; maybe you’ve seen his super-popular video about building his own iPhone “from scratch”. It’s a great story, and it’s also a pretext for a slightly deeper dive into the electronics hardware manufacturing, assembly, and repair capital of the world: Shenzhen, China. After his talk at the 2017 Superconference, we got a chance to sit down with Scotty and ask about cellphones and his other travels. Check it out:

The Story of the Phone

Scotty was sitting around with friends, drinking in one of Shenzhen’s night markets, and talking about how bizarre some things seem to outsiders. There are people sitting on street corners, shucking cellphones like you’d shuck oysters, and harvesting the good parts inside. Electronics parts, new and used, don’t come from somewhere far away and there’s no mail-ordering. A ten-minute walk over to the markets will get you everything you need. The desire to explain some small part of this alternate reality to outsiders was what drove Scotty to dig into China’s cellphone ecosystem.

All Your IPhone Are Belong To Us

March 19, 2018 by Al Williams 46 Comments

Apple’s commitment to customer privacy took the acid test after the San Bernadino shooting incident. Law enforcement demanded that Apple unlock the shooter’s phone, and Apple refused. Court cases ensued. Some people think that the need to protect the public outweighs the need for privacy. Some people think that once they can unlock one iPhone, it won’t stop there and that will be bad for everyone. This post isn’t about either of those positions. The FBI dropped their lawsuit against Apple. Why? They found an Israeli firm that would unlock the phone for about $5,000. In addition, Malwarebytes — a company that makes security software — reports that law enforcement can now buy a device that unlocks iPhones from a different company.

Little is known about how the device — from a company called Grayshift — works. However, Malwarebytes has some unverified data from an unnamed source. Of course, the exploit used to break the iPhone security is secret because if Apple knew about it, they’d fix it. That’s happened before with a device called IP-box that was widely used for nefarious purposes.

Injection Molding IPhone Cases From Trash

February 7, 2018 by Tom Nardi 27 Comments

We imagine you’ve heard this already, but waste plastic is a problem for the environment. We wrap nearly everything we buy, eat, or drink in plastic packaging, and yet very little of it ends up getting recycled. Worse, it doesn’t take a huge industrial process to melt down a lot of this plastic and reuse it, you can do it at home if you were so inclined. So why aren’t there more localized projects to turn all this plastic trash into usable items?

That the question that [Precious Plastic] asks, and by providing a centralized resource for individuals and communities looking to get into the plastic recycling game, they hope to put a dent in the worldwide plastic crisis. One of their latest projects is showing how plastic trash can be turned into functional iPhone cases with small-scale injection molding.

The video after the break goes into intricate detail about the process involved in creating the 3D CAD files necessary to make the injection molds. Even if you don’t plan on recycling milk jugs at home, the information and tips covered in the video are extremely helpful if you’ve ever contemplated having something injection molded. The video even demonstrates a neat feature in SolidWorks that lets you simulate how molten plastic will move through your mold to help check for problem areas.

Once you’ve designed your mold on the computer, you need to turn it into a physical object. If you’ve got a CNC capable of milling aluminum then you’re all set, but if not, you’ll need to outsource it. [Precious Plastic] found somebody to mill the molds through 3DHubs, though they mention in the video that asking around at local machine shops isn’t a bad idea either.

With the mold completed, all that’s left is to bolt the two sides together and inject the liquid plastic. Here [Precious Plastic] shows off a rather interesting approach where they attach the mold to a contraption that allows them to inject plastic with human power. Probably not something you’d want to do if you’re trying to make thousands of these cases, but it does show that you don’t necessarily need a high tech production facility to make good-looking injection molded parts.

This project reminds us of the tiles made of HDPE plastic with nothing more exotic than what you’d find in the average kitchen. Projects like these really drive home the idea that with the right hardware individuals can turn trash into usable products.

Face ID Defeated With 3D Printed Mask (Maybe)

November 14, 2017 by Tom Nardi 44 Comments

Information about this one is still tricking in, so take it with a grain of salt, but security company [Bkav] is claiming they have defeated the Face ID system featured in Apple’s iPhone X [Dead link, try the Internet Archive]. By combining 2D images and 3D scans of the owner’s face, [Bkav] has come up with a rather nightmarish creation that apparently fools the iPhone into believing it’s the actual owner. Few details have been released so far, but a YouTube video recently uploaded by the company does look fairly convincing.

For those who may not be keeping up with this sort of thing, Face ID is advertised as an improvement over previous face-matching identification systems (like the one baked into Android) by using two cameras and a projected IR pattern to perform a fast 3D scan of the face looking at the screen. Incidentally, this is very similar to how Microsoft’s Kinect works. While a 2D system can be fooled by a high quality photograph, a 3D based system would reject it as the face would have no depth.

[Bkav] is certainly not the first group to try and con Apple’s latest fondle-slab into letting them in. Wired went through a Herculean amount of effort in their attempt earlier in the month, only to get no farther than if they had just put a printed out picture of the victim in front of the camera. Details on how [Bkav] managed to succeed are fairly light, essentially boiling down to their claim that they are simply more knowledgeable about the finer points of face recognition than their competitors. Until more details are released, skepticism is probably warranted.

Still, even if their method is shown to be real and effective in the wild, it does have the rather large downside of requiring a 3D scan of the victim’s face. We’re not sure how an attacker is going to get a clean scan of someone without their consent or knowledge, but with the amount of information being collected and stored about the average consumer anymore, it’s perhaps not outside the realm of possibility in the coming years.

Since the dystopian future of face-stealing technology seems to be upon us, you might as well bone up on the subject so you don’t get left behind.

Thanks to [Bubsey Ubsey] for the tip.

Hackaday Links: Remember, Remember

November 5, 2017 by Brian Benchoff 16 Comments

Buckle up, buttercup because this is the last weekly Hackaday Links post you’re getting for two weeks. Why? We have a thing next weekend. The Hackaday Superconference is November 11th and 12th (and also the 10th, because there’s a pre-game party), and it’s going to be the best hardware con you’ve ever seen. Don’t have a ticket? Too bad! But we’ll have something for our Internet denizens too.

So, you’re not going to the Hackaday Supercon but you’d like to hang out with like-minded people? GOOD NEWS! Barnes & Noble is having their third annual Mini Maker Faire on November 11th and 12th. Which Barnes & Noble? A lot of them. Our reports tell us this tends to be geared more towards the younger kids, but there are some cool people doing demonstrations. Worst case scenario? You can pick up a copy of 2600.

PoC || GTFO 0x16 is out! Pastor Laphroaig Races The Runtime Relinker And Other True Tales Of Cleverness And Craft! This PDF is a Shell Script That Runs a Python Webserver That Serves a Scala-Based JavaScript Compiler With an HTML5 Hex Viewer; or, Reverse Engineer Your Own Damn Polyglot.

In, ‘Oh, wow, this is going to be stupid’ news, I received an interesting product announcement this week. It’s a USB C power bank with an integrated hand warmer. Just think: you can recharge your phone on the go, warm your hands in the dead of winter, and hope your random battery pack from China doesn’t explode in your pocket. I’m not linking to this because it’s that dumb.

You can now cross-compile ARM with GCC in Visual Studio.

The iPhone X is out, and that means two things. There are far too many YouTube videos of people waiting in line for a phone (and not the good kind), and iFixit did a teardown. This thing is glorious. There are two batteries and a crazy double-milled PCB stack with strange and weird mezzanine connectors. The main board for the iPhone X is completely unrepairable, but it’s a work of engineering art. No word yet on reusing the mini-Kinect in the iPhone X.

Speaking of irreparable computers, the Commodore 64 is not. [Drygol] recently came across a C64 that was apparently the engine controller for a monster truck found on the bottom of the ocean. This thing was trashed, filled with rust and corrosion, and the power button just fell off. Prior to cleaning, [Drygol] soldered a new power button, bowered it up, and it worked. The crappiest C64 was repairable. A bit of cleaning, painting the case, and the installation of an SD2IEC brought this computer back to life, ready for another thirty years of retrogaming and BASIC.

The Zynq from Xilinx is one of the most interesting parts in recent memory. It’s a dual-core ARM Cortex A9 combined with an FPGA with a little more than a million reconfigurable gates. It’s been turned into a synth, a quadcopter, all of British radio, and it’s a Pynq dev board. Now there’s a new part in the Zynq family, an RFSoC that combines the general ARM/FPGA format with some RF wizardry. It’s designed for 5G wireless and radar (!), and one of those parts we can’t wait to see in use.

Do you keep blowing stuff up when attaching a USB to UART adapter to a board? Never fear, because here’s one with galvanic isolation. This is done with a neat digital isolator from Maxim

Bringing Back The IPhone7 Headphone Jack

September 7, 2017 by Adam Fabio 96 Comments

Plenty of people bemoaned Apple’s choice to drop the 1/8″ headphone jack from the iPhone 7. [Scotty Allen] wasn’t happy about it either, but he decided to do something about it: he designed a custom flex circuit and brought the jack back. If you don’t recognize [Scotty], he’s the same guy who built an iPhone 6 from parts obtained in Shenzhen markets. Those same markets were now used to design, and prototype an entirely new circuit.

The iPhone 7 features a barometric vent, which sits exactly where the headphone jack lived in the iPhone 6. The vent helps the barometric pressure sensor obtain an accurate reading while keeping the phone water proof. [Scotty] wasn’t worried about waterproofing, as he was cutting a hole through the case. The vent was out, replaced with a carefully modified headphone jack.

The next step was convincing the phone to play analog signals. For this, [Scotty] used parts from Apple’s own headphone adapter. The hard part was making all of this work and keeping the lightning port available. The key was a digital switch chip. Here’s how the circuit works:

When no headphone is plugged in, data is routed from the iPhone’s main board to the lightning port. When headphones are plugged in, the data lines are switched to the headphone adapter. Unfortunately, this means the phone can’t play music and charge at the same time — that is something for version 2.0.

The real journey in this video is watching [Scotty] work to fit all these parts inside an iPhone case. The design moved from a breadboard through several iterations of prototype printed circuit boards. The final product is built using a flexible PCB – the amber-colored Kapton and copper sandwiches that can be found in every mobile device these days.

Making everything fit wasn’t easy. Two iPhone screens perished in the process. But ultimately, [Scotty] was successful. He’s open sourced his design so the world can build and improve on it.
