Automated Tea Maker

Posted by wicked January - 29 - 2015 - Thursday Comments Off

[Pariprohus] wanted to make an interesting gift for his girlfriend. Knowing how daunting it can be to make your own tea, he decided to build a little robot to help out. His automated tea maker is quite simple, but effective.

The device runs off of an Arduino Nano. The Nano is hooked up to a servo, a piezo speaker, an LED, and a switch. When the switch is turned to the off position, the servo rotates into the “folded” position. This moves the steeping arm into a position that makes the device easier to store and transport.

When the device is turned on to the “ready” position, the arm will extend outward and stay still. This gives you time to attach the tea bag to the arm and place the mug of hot water underneath. Finally the switch can be placed into “brew” mode. In this mode, the bag is lowered into the hot water and held for approximately five minutes. Each minute the bag is raised and lowered to stir the water around.

Once the cycle completes, the Nano plays a musical tune from the piezo speaker to remind you to drink your freshly made tea. All of the parameters including the music can be modified in the Nano’s source code. All of the components are housed in a small wooden box painted white. Check out the video below to see it in action.

Adding WiFi and SMS to an Alarm System

Posted by wicked January - 17 - 2015 - Saturday Comments Off

[Don] wanted to bring his alarm system into the modern age. He figured that making it more connected would do the trick. Specifically, he wanted his alarm system to send him an SMS message whenever the alarm was tripped.

[Don] first had to figure out a way to trigger an event when the alarm sounds. He found a screw terminal that lead to the siren. When the alarm is tripped, this screw terminal outputs 12V to enable the siren. This would be a good place to monitor for an alarm trip.

[Don] is using an Arduino nano to monitor the alarm signal. This meant that the 12V signal needed to be stepped down. He ran it through a resistor and a Zener diode to lower the voltage to something the Arduino can handle. Once the Arduino detects a signal, it uses an ESP8266 WiFi module to send an email. The address [Don] used is the email-to-SMS address which results in a text message hitting his phone over the cell network.

The Arduino also needed power. [Don] found a screw terminal on the alarm system circuit board that provided a regulated 12V output. He ran this to another power regulator board to lower the voltage to a steady 5V. This provides just the amount of juice the Arduino needs to run, and it doesn’t rely on batteries. [Don] provides a good explanation of the system in the video below.

iRobot Releases Hackable Roomba — Without The Vacuum

Posted by wicked December - 22 - 2014 - Monday Comments Off

We love forward thinking companies that take a risk and do something different. iRobot, the company behind the iconic Roomba, just released the newest version of their Roomba Create — a programmable Roomba (minus the vacuum) that can be hacked and programmed to do all sorts of things.

The company developed the Create with STEM students in mind — a robotics learning platform. It came out originally back in 2007, and we’ve covered many hacks that have made use of it. Many. Like, a lot. One of our favorites has got to be this data center monitoring robot that makes use of the platform!

Anyway, the newest version of the Create features the typical hardware upgrades you’d expect, and with some special emphasis on 3D printing. In fact, the CEO of iRobot [Colin Angle] thinks that 3D printing is going to make a big difference in a few years:

“Your Roomba could be a software file that you print at home,” he says. He says the Create’s new features are a way for the company to get ready for that day, while also providing a platform that educators and hobbyists can use to tinker.

Kudos to you guys, iRobot! We just wish people would stop giving Roomba’s knives…

[Thanks PSUbj21!]

Here’s how to enable the hidden reader mode in Chrome for Android

Posted by wicked December - 5 - 2014 - Friday Comments Off

google_chromeOne of the most inconsistent things I’ve noticed on my Note 4 is that some web sites are hard to read. With varying formatting, it can sometimes be a process having to zoom in and out, moving the page back and forth, etc. Well Chrome for Android has your back as it now has a hidden reader mode. Reader mode will strip away that annoying formatting. Here’s how to enable it.

In the latest version of Chrome for Android (I enabled it in Chrome Beta) type chrome://flags in the address bar. Once there, hit the menu option and go to Find on Page. Search for “Enable Reader Mode Toolbar Icon.” Tap enable and hit Relaunch Chrome. Easy as that. If you’re on a compatible page you’ll see an A with lines next to it (see below). If you tap it, you’ll get a more streamlined version of the page you’re on, making it easier to read.

ChromeReader

That said, it’s still an experimental feature, so mileage may vary. It does have the potential to get rid of some of the stuff you want to look at (such as pictures and video) but it may come in handy for those that want to read an article without all the formatting fluff.

Nothing’s as Vain as a Phone Taking a Selfie of Itself… with Itself

Posted by wicked November - 12 - 2014 - Wednesday Comments Off

The selfie: pop culture’s most frivolous form of self-expression is also probably one of the most human acts you could find yourself doing in a day. Everyone is guilty of snapping a quick pic from time to time with the expectation that it will leave an impression on those who see it. All of the implications surrounding why we do this support our deep-seated need to sculpt an identity for ourselves using others as the hammer and chisel. So, consider how upside-down the world would feel if you caught a robot posing for a shot in the mirror? What about one whose sole function was to take selfies and post them? If this breaks your mind a little, that was the intention. This #selfie robot by artists [Radamés Ajna] and [Thiago Hersan] is the first development in a larger body of work called “memememe”, which is meant to comment on our culture’s obsession with the trending, selfing nature of social media. This specific project explores the relationship between conversation and identity in a situation where there is no second party.

selfieBOT2Hardware-wise, the #selfie bot is a Stewart platform made from six servo motors and a few pieces of carefully measured pushrod connected with swivel-ball-links. An android phone is mounted on the end effector which acts functionally as the robot’s face and eyes. To make it self-aware in a sense, [Ajna] and [Hersan] created their own recognition software with Open CV using a collection of sample images of various phones as reference points. As soon as the robot recognizes itself in the mirror as indicated by specific words flashing on its screen, it takes a picture, immediately uploading it to its own tumblr account. [Ajna] and [Hersan] have a nice description of their process on the project’s Instructable’s page which you can check out to see how they used Haar Cascades to create their custom object recognition. Additionally, if you’d fancy building your own robot to covertly place in your living room to snap pictures of other phones, you could check out their code on github.

Watch it selfie :

LG_G3_Back_Rear_Controls_LG_Logo_TA

So far, LG has only pushed the Lollipop update to the G3 in Poland, but that won’t stop others from enjoying it. If you have the European model (D855), Skin1980 from XDA has a surprise for you.

He put together a flashable Zip that’s even rootable. You will need the TWRP recovery installed and you will need to do a factory reset. If this is something that interests you, hit the source link below for full instructions, and be sure to consider giving Skin1980 a donation because I’m sure this took a lot of work.

Ceci N’est Pas Une Clock

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

[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

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.
