You Can Add Wireless Charging To IPhone… Kinda

August 26, 2018 by Mike Szczys 9 Comments

We could watch cellphone teardown videos all day long. There’s something pleasing about seeing how everything is packed into such a small enclosure. From the connectors, to that insidious glue, to the minuscule screws, [Scotty Allen] has a real knack for giving us a great look at the teardown process. Take a look at his latest video which attempts to add wireless charging to an iPhone. I think there’s a lot to be said for superb lighting and a formidable camera, but part of this is framing the shots just right.

Now of course we’ve taken apart our fair share of phones and there’s always that queasy “I think I’m going to break something” feeling while doing it. It’s reassuring that [Scotty] isn’t able to do things perfectly either (although he has the benefit of walking the markets for quick replacement parts). This video is a pretty honest recounting of many things going wrong.

The iPhone 6 and 7 are not meant to have wireless charging, but [Scotty’s] working with a friend named [Yeke] who created an aftermarket kit for this. The flexible PCB needs to be folded just right, and adhesive foam added (along with a magical incantation) to make it work. That’s because the add-on is a no-solder job. Above you can see it cleverly encircles one of the mating connectors and relies on mechanical pressure to make contact with the legs of that connector. Neat!

In the second half of the video [Scotty] meets up with [Yeke] to discuss the design itself. We find it interesting that [Yeke] considers his work a DIY item. Perhaps it’s merely lost in translation, but perhaps [Yeke’s] proximity to multiple flexible PCB manufacturers makes him feel that this is more like playing around for fun than product design. Any way you look at it, the ability to design something that will fit inside that crazy-tight iPhone case is both impressive and mesmerizing. Having seen some of the inductive charging hacks over the years, this is by far the cleanest way to go about it.

We caught up with [Scotty] during last year’s Supercon. We may not be able to drop everything and move to Shenzhen, but hearing about the experience is just enough to keep us wanting to!

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.

Test Ideas Now With Sensors Already In Your Pocket

March 20, 2018 by Roger Cheng 15 Comments

When project inspiration strikes, we’d love to do some quick tests immediately to investigate feasibility. Sadly we’re usually far from our workbench and its collection of sensor modules. This is especially frustrating when the desired sensor is in the smartphone we’re holding, standing near whatever triggered the inspiration. We could download a compass app, or a bubble level app, or something similar to glimpse sensor activity. But if we’re going to download an app, consider Google’s Science Journal app.

It was designed to be an educational resource, turning a smartphone’s sensor array into a pocket laboratory instrument and notebook for students. Fortunately it will work just as well for makers experimenting with project ideas. The exact list of sensors will depend on the specific iOS/Android device, but we can select a sensor and see its output graphed in real-time. This graph can also be recorded into the journal for later analysis.

Science Journal was recently given a promotional push by the band OK Go, as part of their OK Go Sandbox project encouraging students to explore, experiment, and learn. This is right up the alley for OK Go, who has a track record of making music videos that score high on maker appeal. Fans would enjoy their videos explaining behind-the-scene details in the context of math, science, and music.

An interesting side note. Anyone who’s been to Hackaday Superconference or one of the monthly Hackaday LA meetups will likely recognized the venue used in many of the OK Go Sandbox videos. Many of them were filmed at the Supplyframe Design Lab in Pasadena. It’s also nice to see AnnMarie Thomas (Hackaday Prize Judge from 2016 and 2017) collaborated with OK Go for the Sandbox project.

While the Science Journal app has provisions for add-on external sensors, carrying them around would reduce its handy always-available appeal. Not that we’re against pairing smartphones with clever accessories to boost their sensing capabilities: we love them! From trying to turn a smartphone into a Tricorder, to an inexpensive microscope, to exploring serious medical diagnosis, our pocket computers can do it all.

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.

Dig Into The Apple Device Design Guide

December 29, 2017 by Roger Cheng 8 Comments

Millions of people worldwide have just added new Apple gadgets to their lives thanks to the annual end of December consumerism event. Those who are also Hackaday readers are likely devising cool projects incorporating their new toys. This is a good time to remind everybody that Apple publishes information useful for such endeavors: the Accessory Design Guidelines for Apple Devices (PDF).

This comes to our attention because [Pablo] referenced it to modify an air vent magnet mount. The metal parts of a magnetic mount interferes with wireless charging. [Pablo] looked in Apple’s design guide and found exactly where he needed to cut the metal plate in order to avoid blocking the wireless charging coil of his iPhone 8 Plus. What could have been a tedious reverse-engineering project was greatly simplified by Reading The… Fine… Manual.

Apple has earned its reputation for hacker unfriendliness with nonstandard fasteners and liberal use of glue. And that’s even before we start talking about their digital barriers. But if your project doesn’t involve voiding the warranty, their design guide eliminates tedious dimension measuring so you can focus on the fun parts.

This guide is packed full of dimensioned drawings. A cursory review shows that they look pretty good and aren’t terrible at all. Button, connector, camera, and other external locations make this an indispensable tool for anyone planning to mill or print an interface for any of Apple’s hardware.

So let’s see those projects! Maybe a better M&M sorter. Perhaps a time-lapse machine. Or cure your car’s Tesla envy and put a well-integrated iPad into the dashboard.

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.

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.
