Unlock & Talk: Open Source Bootloader & Modem

During the early years of cell phones, lifespan was mainly limited by hardware (buttons wearing out, dropping phones, or water damage), software is a primary reason that phones are replaced today. Upgrades are often prompted by dissatisfaction with a slow phone, or manufacturers simply stopping updates to phone software after a few years at best. [Oliver Smith] and the postmarketOS project are working to fix the update problem, and have begun making progress on loading custom software onto cellphone processors and controlling their cellular modems.

Since [Tom Nardi] introduced Hackaday readers to postmarketOS, the team has made progress on compiling …read more

Test Ideas Now With Sensors Already In Your Pocket

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 …read more

All Your iPhone Are Belong To Us

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 …read more

Regrowing a Blackberry from the Keyboard Out

Here at Hackaday we’re big fans of device-reuse, and what [arturo182] has done with the Blackberry Q10’s keyboard is a fantastic example. Sometimes you’re working on a portable device and think to yourself “what this could really use is a QWERTY keyboard”. What project doesn’t need a keyboard?

Typically this descends into a cost benefit analysis of the horrors of soldering 60ish SMD tact switches to a board, which is no fun. With more resources you can use Snaptron snap domes like the [NextThingCo’s] PocketCHIP, but those are complex to source for a one off project and the key feel …read more

HandHolo: A Homebrew ARG

Taking a dive into VR or augmented reality — once, dreamed-of science fiction — is not only possible for the average consumer, but crafting those experiences is as well! Hackaday.io user [kvtoet]’s HandHolo is a homebrew method to cut your teeth on peeking into a virtual world.

This project requires a smartphone running Android Oreo as its backbone, a Bluetooth mouse, a piece of cardboard and a small mirror or highly reflective surface. The phone is slotted into the cardboard housing — prototype with what you have! — above the mouse, and the mirror angled opposite the screen reflects the …read more

Cell Phone Surveillance Car

There are many viable options for home security systems, but where is the fun in watching a static camera feed from inside your place? The freedom to really look around might have been what compelled [Varun Kumar] to build a security car robot to drive around his place and make sure all is in order.

Aimed at cost-effectiveness and WiFi or internet accessibility, an Android smartphone provides the foundation of this build — skipping the need for a separate Bluetooth or WiFi module — and backed up by an Arduino Uno, an L298 motor controller, and two geared DC motors …read more

Easy Time-lapse Video via Phone and Command Line

A good time-lapse video can be useful visual documentation, and since [Tommy]’s phone is the best camera he owns he created two simple shell scripts to grab time-lapse images and assemble them into a video. [Tommy]’s work is just the glue between two other things: an app that turns the phone into an IP camera with a web server on the local network, and the ability to grab a still image from that server on demand.

The app he uses for his iPhone normally serves video but has an undocumented feature that allows single frames to be downloaded by adding …read more

Detecting Dire Diseases – with a Selfie?

They say the eyes are the windows to the soul. But with a new smartphone app, the eyes may be a diagnostic window into the body that might be used to prevent a horrible disease — pancreatic cancer. A research team at the University of Washington led by [Alex Mariakakis] recently described what they call “BiliScreen,” a smartphone app to detect pancreatic disease by imaging a patient’s eyes.

Pancreatic cancer is particularly deadly because it remains asymptomatic until it’s too late. One early symptom is jaundice, a yellow-green discoloration of the skin and the whites of the eyes as the …read more

Automatic Phone Dialer Illuminates Inner Workings

The invention of the transistor ushered in a lot of technologies that we now take for granted, and one of the less-thought-about areas that it improved living conditions worldwide was by making the touch-tone phone possible. No longer would the world have to fuss with dials to make phone calls, they could simply push some buttons. This technology is still in use today, and it is possible to build external phone dialers that use these tones to make phone calls, as [SunFounder] demonstrates with his latest project.

The tones that a phone makes when a button is pressed correlate with …read more

Fix-A-Brick 2: Nexus 5X Rises From the Ashes

It was but two weeks ago when I told my story of woe —  the tale of an LG Nexus 5X that fell ill, seemingly due to a manufacturing fault at birth. I managed to disassemble it and made my way through a semi-successful attempt at repair, relying on a freezer and hairdryer to coax it back to life long enough to backup my data. Try as I might, however, I simply couldn’t get the phone running for more than ten minutes at a time.

All was not in vain, however! I was rewarded for documenting my struggles with the …read more
