Ceci N’est Pas Une Clock

Posted by wicked October - 22 - 2014 - Wednesday Comments Off

notclock

[Justin] tipped us about his slick custom OBD-II gauge that could easily pass for an OEM module. He was able to use the clock area of his Subaru BRZ to display a bunch of information including the oil and coolant temperatures and the battery voltage.

The forum post linked above has a good FAQ-based explanation of what he did, but so many people have told him to shut up and take their money that he created an Instructable for it. Basically, he’s got a Sparkfun OBD-II UART board communicating with a pro Trinket. The display is an Adafruit OLED, which he found to be an ideal choice for all the various and sundry light conditions inside the average car.

[Justin] was able to reuse the (H)our and (M)inute buttons and reassigned them to (H)igh to show the peak reading and (M)ode to, well, switch between modes. The (:00) now resets the peak readings. He offers suggestions for acquiring the specific CAN codes for your car to make the data more meaningful. [Justin]‘s code is safe in the many tentacles of Octocat, and you can check out his demo video below.

Controlling a Flip-Disc Display Using Android

Posted by wicked October - 21 - 2014 - Tuesday Comments Off

Android Flip Dot Display

There’s just something about electro-mechanical displays that enthralls most people when they see them; and while you’ll be hard pressed to find a split-flap display for cheap, you can still easily buy flip-disc displays! That’s what [Scott] did, and he’s been having a blast messing around with his and building a system to control it via his Android phone.

He picked up the display from a company called Alfa-Zeta in Poland, a company that’s been making electromagnetic displays since 1988. No mention of price, but it looks like some pretty awesome hardware. The beauty with electromagnetic displays is they don’t consume any electricity in idle state, making them far more efficient than almost any other display technology – not to mention perfect contrast in any lighting conditions!

They work by using permanent magnets, electromagnets, and a material that can retain magnetization. A short pulse to the electromagnet causes the disc to flip into the second position, which will then hold in place due to the permanent magnet — no more electromagnet needed.

The display comes with all the necessary hardware to drive the electromagnets and interface with a microcontroller. But, it uses the RS-485 standard, which isn’t natively supported by most other microcontrollers. [Scott's] using an Arduino which does have an RS-485 shield, but he decided he wanted to challenge himself and build a circuit to drive them himself!

All the info is on his blog if you’re looking to try something similar. Once he had it interfaced with the Arduino it was just a simple matter of writing an Android app to transmit controls over Bluetooth for the display. Take a look:

And some slow motion for you:

If split-discs aren’t mechanical enough for you, you can always try building your own split-flap display…

Dropbox usernames and passwords leak online, Denies responsibility and says passwords expired

Posted by wicked October - 14 - 2014 - Tuesday Comments Off

dropbox_app_icon

It seems like just about every day there is some sort of hack involving an online service. Today’s hack is from Dropbox.

A user posted files on Reddit that contained a bunch of usernames and passwords for Dropbox accounts. The poster said there were close to 7,000,000 more, but asked for Bitcoin donations to reveal them.

Later, Dropbox made a statement to The Next Web saying that they are not to be blamed, and they were stolen from other third party services……

Dropbox has not been hacked. These usernames and passwords were unfortunately stolen from other services and used in attempts to log in to Dropbox accounts. We’d previously detected these attacks and the vast majority of the passwords posted have been expired for some time now. All other remaining passwords have been expired as well.

Dropbox also said they performed password resets when it detected any suspicious activity on these accounts, which was a few months ago.

Timelapse Photography on an Android-Powered Dolly

Posted by wicked October - 11 - 2014 - Saturday Comments Off

camera dolly

If you’re heading off on a trip to Alaska, you need to make sure you have plenty of supplies on hand for the wilderness that awaits. If you’re [Bryce], that supply list includes some interesting photography equipment, including a camera dolly that he made to take time-lapse video of the fantastic scenery.

On the hardware side, the dolly carries the camera on a rail that is set up on a slant. The camera starts on one side and moves up and towards the otherside which creates a unique effect in the time-lapse. The rig is driven by a stepper motor, and rides on some pretty fancy bearings. The two cameras [Bryce] plans to use are a Canon T2i and a EOS-M which sit on the top from a tripod.

The software and electronics side is interesting as well. Instead of the usual Arduino, [Bryce] opted for controlling the rig through Android and a IOIO board. This gives the project a lot of options for communications, including Bluetooth. The whole thing is powered by a 19V battery pack. If you’re looking for something a little simpler, you might want to check out the egg timer for time lapse! Check out the video of [Bryce]‘s rig in action after the break.

Non-Sony Android devices get access to Sony PS4 Remote Play thanks to new port

Posted by wicked September - 23 - 2014 - Tuesday Comments Off

xda_ps4_remote_play_port

When Sony announced their new Xperia Z3 smartphones during IFA 2014, one of the new features included was PS4 Remote Play. This new feature meant owners of the new devices could use their Sony smartphones as a second screen for the their Sony PS4 gaming platform. Even better than that, users could continue to play PS4 titles remotely on their mobile device. This was some great news for gamers who had PlayStation 4 devices if they were going to invest in a new Sony smartphone. Unfortunately, a Sony spokesperson said the company had “no intent to bring remote play to any device other than Xperia” meaning a lot of PlayStation 4 owners would miss out on the feature. That may have changed now thanks to a new port developed by XDA member XperiaPlaystation who has figured out how to get it working with a much larger population of Android devices.

According to XperiaPlaystation, the ported app should work with Android devices running at least Android 4.0 or newer. Users do have to install CWM (ClockWorkMod) Recovery, then flash a ZIP file, follow a couple other steps to clean up the device, and then install the APK file. Oddly enough, owners of a Sony Xperia Z1 have an additional step related to changing their build.prop in order to get the ported app to work.

If you have a PlayStation 4 and want to give the PS4 Remote Play app a try and you are willing to do some work on your device, hit the source link below for more detailed instructions and links to the appropriate files.

Chromecast Is Root

Posted by wicked August - 25 - 2014 - Monday Comments Off

Chromecast

Image from [psouza4] on the xda-developers forum

Chromecast is as close as you’re going to get to a perfect device – plug it in the back of your TV, and instantly you have Netflix, Hulu, Pandora, and a web browser on the largest display in your house. It’s a much simpler device than a Raspi running XBMC, and we’ve already seen a few Chromecast hacks that stream videos from a phone and rickroll everyone around you.

Now the Chromecast has been rooted, allowing anyone to change the DNS settings (Netflix and Hulu users that want to watch content not available in their country rejoice), and loading custom apps for the Chromecast.

The process of rooting the Chromecast should be fairly simple for the regular readers of Hackaday. It requires a Teensy 2 or 2++ dev board, a USB OTG cable, and a USB flash drive. Plug the Teensy into the Chromecast and wait a minute. Remove the Teensy, plug in the USB flash drive, and wait several more minutes. Success is you, and your Chromecast is now rooted.

Member of Team-Eureka [riptidewave93] has put up a demo video of rooting a new in box Chromecast in just a few minutes. You can check that out below.

The BlueOkiris Gameduino Console

Posted by wicked August - 2 - 2014 - Saturday Comments Off

3011851406903369314

[Dylan] created an easy to make gaming console with an Arduino Uno, a makeshift button, an analog stick, and a TFT LCD touchscreen shield. Plus, he fashioned together a simple button with some duct tape.

So far, he has made 2 games. One is the infamous Pong. The other is a ‘Guess the Number’ type experience. The whole project is run within the code, and does not access the bootloader directly like you would with 2boots or a regular Gameduino adapter.

Build instructions can be found on [Dylan]’s hackaday.io project page (linked above). Essentially, all that is needed is to gather up the supplies, then take the button and analog stick and complete a circuit, fitting the open wires into the slots at digital pin 9. Solder the wires in place and connect ground to ground, 5v to 5v, x to A4, and y to A5. Add the TFT shield, insert a micro SD card, and upload a game.

To see it in action, check out the video after the break:

And there you go! An Arduino game console.

Other projects similar to this include a credit card-sized Gameboy and UnoJoy, which makes your Arduino play well with an Xbox 360 or PS3.

LG G Watch gets toolkit for rooting, unlocking, flashing and restoring capabilities

Posted by wicked July - 27 - 2014 - Sunday Comments Off

LG_G_Watch_Main_Screen_On_TA

The Nexus Root Toolkit from Wugfresh has become insanely popular since the interest in unlocking bootloaders and rooting devices has expanded to “normal” consumers.

Now, those with an LG G Watch will be able to root and unlock the device just as easily as Wugfresh’s Nexus solution provides.

Created by XDA developer Tomsgt, the LG G Watch Tool prepares your watch for aftermarket development and modification. You’ll be able to do the following with the toolkit:

  • Unlock/relock the bootloader
  • Flashing stock recovery
  • Flashing stock boot image
  • Restoring the device if bricked
  • Rooting the G Watch
  • Installing and testing necessary drivers

The XDA Developers forum says you can run the toolkit on Windows, Linux and iOS (although we’re pretty sure they meant OS X).

You can check out the tutorial video below provided by Tomsgt if you’re trying this out for the first time. Since he also included a restore feature in the toolkit, it would pretty tough to brick your device beyond repair — especially since most of these processes are nearly 100% automated by a script.

Self-Balancing Robot Uses Android and Lego NXT

Posted by wicked July - 17 - 2014 - Thursday Comments Off

LEGO NXT + Android = Self Balancing Robot

Self-balancing robots are pretty cool, but sometimes a bit too complex to make. [HippoDevices] shows us that it’s really not that hard, and you can even do it with Lego NXT and an Android device!

First step is to build your two-wheeled robot – go nuts! As long as the Lego NXT motors are strong enough you’ll be able to make most different shaped robots easy to balance. You’re going to need an Android ADK board to provide communication between the Lego motors and your Android device. [HippoDevices] is using their own design, called the Hippo-ADK which is on Kickstarter currently.

This allows your Android device to read the status and control the Lego Motors — from there it’s just a matter of programming it to balance according to the device’s gyroscope.

And since you already have a smart device on your robot, you can control it with another Android device!

[Thanks Zipper!]

The Future Of Distraction, Right In Front Of Your Face

Posted by wicked July - 9 - 2014 - Wednesday Comments Off

Bird

Say you’re meeting someone new, and instead of communicating like a normal person that wasn’t born in a barn, they play with their phone the entire time. How about a cashier or sales person who is so insufferably distracted with the Facebooks you’d guess they had a side job in the QA department of some developer? All these things will soon be a distant, horrible memory, because now you can play Flappy Bird on Google Glass.

[Rich] has had his Glass for a while now, and has been meaning to write an app for it. It took a little bit of inspiration, but when the idea of using the eye sensor to control everyone’s favorite 8-bit bird, everything fell into place. It ended up being an interesting use for the Glass, and something we actually wouldn’t mind trying out.

The bird is controlled by a double blink. In the video below, you can see there might be a little bit of latency depending on how [Rich] put the video together. Better grab that .APK while there’s still time. [Rich] says it’s a free download for anyone who’s already overpaid for a Google Glass.
