Dual SIM Hack For Single SIM Slot Phones.

Posted on by

[RoyTecTips] shows us an ingenious hack which turns a single-SIM-slot phone into a fully functioning dual-SIM phone. All that needed for this hack is a heat-gun, solvent, micro SD card, nano SIM and some glue. The trick is that the phone has a SIM reader on the backside of an SD-card slot. Through some detailed dissection and reconstruction work, you can piggy-back the SIM on the SD card and have them both work at the same time.

Making the SD/SIM Franken-card is no picnic. First you start by filing away the raised bottom edge of the micro SD card and …read more

Pi Zero W Impersonates iPhone, Becomes Terminal

Posted on by

There’s something to be said for economies of scale and few things sell more than cell phones. Maybe that’s why [NODE] took inspiration from an iPhone slide out keyboard case to create this Pi Zero W-based portable terminal. This is actually his third iteration, and in the video below he explains why he has built the new version.

By housing the custom bits in a 3D-printed frame that is size compatible with the iPhone, [NODE] manages to leverage the slick slide out keyboard cases available for the phone. The iPhone in question is an older iPhone 5, so the cases …read more

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

Posted on by

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, …read more

iPhone Brain Surgery

Posted on by

You think you’re good at soldering? Can you solder a CPU? A CPU inside an iPhone? A decapped CPU inside an iPhone? Can you solder inside a decapped CPU inside of an iPhone?

If you can’t, fear not – someone can, and we found him or her courtesy of a video that [Bunnie Huang] tweeted a while back. There’s not much information in the video, but from what we can gather it comes from an outfit called G-Lon Technology in Guang Zhou. Their Facebook page suggests that they teach cellphone repair, and if they take their repairs this far, we’d …read more

Nexus 5X Phone Resurrected By The Oven

Posted on by

Warranty shmarranty — toss the phone in the oven! There’s apparently a problem with the assembly of the Nexus 5X smartphones, and it looks like it is due to faulty BGA chip soldering. LG USA has had enough problems with the phone that they may not even have enough parts or new units to fix it, so they’re offering a refund. But we all know how it is to get attached to a device, right?

So [Alex] disassembled his beloved phone, pulled out the board in question, and gave it the XBox Red Ring Of Death treatment. He placed the …read more

Live Counter Revives Old Nokia Phone’s Utility

Posted on by

Old hardware you may have on hand cannot only inspire projects in their own right, but can facilitate the realization of any ideas you have been planning. Using a Nokia N900, [MakerMan] concocted a light-up sign with a live subscriber and view count of his videos.

[MakerMan] milled out the logo used on the sign with his DIY CNC machine — built from rotary bearings and recycled stepper motors off industrial Xerox printers. The meticulous application of a jigsaw, rotary tool, and grinder resulted in a sturdy frame for the sign while a few strips of RGB LEDs imbue it …read more

Camera Restricta Ensures Original Photography

Posted on by

Proper documentation is important, and when traveling it is commonly achieved via photography. Redundant documentation is often inefficient, and the Camera Restricta — in a commentary on the saturation of photographed landmarks and a recent debate on photographic censorship in the EU — aims to challenge the photographer into taking unique photographs.

Camera Restricta has a 3D-printed body, housing a smartphone for gps data, display and audio output, while an ATTiny85 serves to control the interdicting function of the camera. When the user sets up to take a picture using Camera Restricta, an app running on the phone queries a …read more

Stadium Sized Cellphone Light Show Is Controlled By Sound

Posted on by

18 months ago, [Jameson Rader] didn’t know how to code. He had an economics degree and worked for a minor league hockey team. He did have a dream, though. Broadcasting data through sound. When we say broadcast, we mean broadcast – as in one sender and thousands of receivers.

[Jameson] didn’t have the money to hire a team to build his application. So he did what any self-respecting hacker would do. He bought a few books and taught himself to code. We’re talking about a smartphone app here, so Java and Objective-C were necessary to cover Android and iOS devices. …read more

Building Beautiful Cell Phones Out Of FR4

Posted on by

Over on Hackaday.io, [bobricius] took this technology and designed something great. It’s a GSM cell phone with a case made out of FR4. It’s beautiful, and if you’re ever in need of a beautifully crafted burner phone, this is the one to build.

The components, libraries, and toolchains to build a cellphone from scratch have been around for a very long time. Several years ago, the MIT Media Lab prototyped a very simple cellphone on a single piece of FR4. It made calls, but not much else. It was ugly, but it worked. [Bobricius] took the idea and ran with …read more
