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 http://pje.fyi/QDf3Gb

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 http://pje.fyi/QDMzt8

A Salty Solution for a Dead Nexus 5X

If you’re an Android fan, there’s a good chance you’ve heard of the Nexus 5X. The last entry in Google’s line of low-cost Nexus development phones should have closed the program on a high note, or at the very least maintained the same standards of quality and reliability as its predecessor. But unfortunately, a well known design flaw in the Nexus 5X means that the hardware is essentially a time-bomb. There are far too many reports of these phones entering into an endless bootloop right around the one year mark to say it’s just a coincidence.

The general consensus seems …read more http://pje.fyi/QBWj52

Edward Snowden Introduces Baby Monitor for Spies

Famed whistleblower [Edward Snowden] has recently taken to YouTube to announce Haven: an Open Source application designed to allow security-conscious users turn old unused Android smartphones and tablets into high-tech monitoring devices for free. While arguably Haven doesn’t do anything that wasn’t already possible with software on the market, the fact that it’s Open Source and designed from the ground up for security does make it a bit more compelling than what’s been available thus far.

Developed by the Freedom of the Press Foundation, Haven is advertised as something of a role-reversal for the surveillance state. Instead of a smartphone’s …read more http://pje.fyi/Q7RNvR

Is It A Stupid Project If You Learn Something From The Process?

Fidget spinners — so hot right now!

[Ben Parnas], and co-conspirator in engineering inanity [Greg Daneault], brought to the recent Boston Stupid Hackathon in Cambridge, MA, their IoT-enabled Fidget Spinner…. spinner. A Spidget Finner. Yep, that’s correct: spin the smartphone, and the spinner follows suit. Stupid? Maybe, but for good reason.

Part satire on cloud tech, part learning experience, a curt eight hours of tinkering brought this grotesque, ESP32-based device to life. The ESP can the Arduino boot-loader, but you’ll want to use the ESP-IDF sdk, enabling broader use of the chip.

Creating an app that pulls data from the …read more http://pje.fyi/PRgf02

A Minority Report Arduino-Based Hand Controller

Movies love to show technology they can’t really build yet. Even in 2001: A Space Oddessy (released in 1968), for example, the computer screens were actually projected film.  The tablet they used to watch the news looks like something you could pick up at Best Buy this afternoon. [CircuitDigest] saw Iron Man and that inspired him to see if he could control his PC through gestures as they do on that film and so many others (including Minority Report). Although he calls it “virtual reality,” we think of VR as being visually immersed and this is really just the glove, …read more http://pje.fyi/PPmGBr

OpenSTF Dock Ready to Farm Clicks

Deep in the heart of a Chinese click farm — and probably used by the company your company hired to build an ‘app’ — is a magical device. Call it a Beowulf Cluster of Phones. Call it the farm. By any name, it’s a whole bunch of smartphones, smart watches, tablets, and other Smart Things all controlled remotely. This is OpenSTF, or a Smartphone Test Farm. You can build your own, but as with anything requiring a whole lot of cables and devices, if you don’t plan it well, it’s going to look like crap.

[Paul] needed an OpenSTF device …read more http://pje.fyi/PGMkqy
