Sudo Google Assistant

May 16, 2017 by James Hobson 18 Comments

A Raspberry Pi kicking around one’s workbench is a project waiting to happen — if they remain unused long enough to be considered a ‘spare.’ If you find you’ve been pining after an Alexa or your own personal J.A.R.V.I.S., [Novaspirit Tech] might be able to help you out — provided you have a USB mic and speaker handy — with an accessible tutorial for setting up Google Assistant on your Pi.

A quick run-through on enabling a fresh API client on Google’s cloud platform, [Novaspirit] jumps over to the Raspbian console to start updating Python and a few other dependencies. Note: this is being conducted in the latest version of Raspbian, so be sure to update before you get underway with all of your sudos.

Once [Novaspirit] gets that sorted, he sets up an environment to run Google Assistant on the Pi, authenticates the process, and gets it running after offering a couple troubleshooting tips. [Novaspirit] has plans to expand on this further in the near future with some home automation implementation, but this is a great jumping-off point if you’ve been looking for a way to break into some high-tech home deliciousness — or something more stripped-down — for yourself. Check out the video version of the tutorial after the break if you like watching videos of guys typing away at the command line.

Google AIY: Artificial Intelligence Yourself

May 4, 2017 by Inderpreet Singh 35 Comments

When Amazon released the API to their voice service Alexa, they basically forced any serious players in this domain to bring their offerings out into the hacker/maker market as well. Now Google and Raspberry Pi have come together to bring us ‘Artificial Intelligence Yourself’ or AIY.

A free hardware kit made by Google was distributed with Issue 57 of the MagPi Magazine which is targeted at makers and hobbyists which you can see in the video after the break. The kit contains a Raspberry Pi Voice Hat, a microphone board, a speaker and a number of small bits to mount the kit on a Raspberry Pi 3. Putting all of it together and following the instruction on the official site gets you a Google Voice Interaction Kit with a bunch of IOs just screaming to be put to good use.

The source code for the python app can be downloaded from GitHub and consists of a loop that awaits a trigger. This trigger can be a press of a button or a clap near the microphones. When a trigger is detected, the recorder function takes over sending the stream to the Google Cloud. Speech-to-Text conversion happens there and the result is returned via a Text-To-Speech engine that helps the system talk back. The repository suggests that the official Voice Kit SD Image (893 MB download) is based on Raspbian so don’t go reflashing a memory card right away, you should be able to add this to an existing install.

Burger King Scores Free Advertising From Google Home With A Whopper Of A Hack

April 14, 2017 by Adam Fabio 67 Comments

Advertisers are always trying to stuff more content into a 15 or 30 second TV spot. Burger King seems to have pulled it off with a series of ads that take advantage of the Google Home device sitting in many viewers living rooms. It works like this: The friendly Burger King employee ends the ad by saying “Ok Google, what is the Whopper burger?” Google home then springs into action reading the product description from Burger King’s Wikipedia page.

Trolls across the internet jumped into the fray. The Whopper’s ingredient list soon included such items as toenail clippings, rat, cyanide, and a small child. Wikipedia has since reverted the changes and locked down the page.

Google apparently wasn’t involved in this, as they quickly updated their voice recognition algorithms to specifically ignore the commercial. Burger King responded by re-dubbing the audio of the commercial with a different voice actor, which defeated Google’s block. Where this game of cat and mouse will end is anyone’s guess.

This event marks the second time in only a few months that a broadcast has caused a voice-activated device to go rogue. Back in January a disk jockey reporting a story about Amazon’s Echo managed to order doll houses for many residents of San Diego.

With devices like Alexa and Google home always ready to accept a command, stories like this are going to become the new normal. The only way to avoid it completely is to not allow it in your home. For those who do have a voice-activated device, be very careful what devices and services you connect it to. Internet of things “smart” door locks are already providing ways to unlock one’s door with a voice command. Burglarizing a home or apartment couldn’t be easier if you just have to ask Siri to unlock the door for you. And while some complained about the lack of security in the Zelda hack, we’d rate that as a thousand times more secure than a voice recognition system with no password.

The Smallest Google Street View In Miniatur Wunderland

January 17, 2016 by James Hobson 10 Comments

The world’s largest model railway exhibit — on display in Germany of course — is quite the attraction. The huge Miniatur Wunderland features towns and trains from Germany, Switzerland, Austria, and even a little America. And it’s all on Google Maps.

[Frank] accepted the challenge to build a tiny Google Streetview train, capable of traversing the entire Wunderland. It features a fish-eye camera on both the front and rear car, and is powered by an Arduino — the Wattuino Nanite 85. He upgraded the train to use tiny stepper motors to allow for precise movement along the tracks to get all the shots in perfect Streetview fashion.

Google OnHub Can Has Root

October 7, 2015 by Brandon Dunson 26 Comments

It’s always nice to get down to the root directory of a device, especially if the device in question is one that you own. It’s no huge surprise that a Google product allows access to the root directory but the OnHub requires locating the hidden “developer mode” switch which [Maximus64] has done. The Google engineers have been sneaky with this button, locating it at the bottom of a threaded screw hole. Has anyone seen this implemented on other hardware before?

There isn’t a blog post regarding this, however [Maximus64] shared a video on YouTube walking us through the steps to root and un-root Google’s OnHub, which is embedded after the break. He also states “wiki coming soon” in the description of the video, so we’ll keep eye on it for an update.

We covered the product announcement back in August and have heard a few reviews/opinions about the device but not enough to make an opinionated assumption. Rooting the device doesn’t seem to increase the OnHub’s number of LAN ports but we think it’s still worth the effort.

Trick Google Used Hides Secret Messages On LCD Screens

July 15, 2015 by Adam Fabio 37 Comments

[Travis] didn’t get picked to go to Google I/O this year, but he did have some I/O inspired fun after the fact. His friends who did go told him about specially modified LCD screens Google had scattered around the event. The screens showed normal show information when viewed with the naked eye. When viewed through a special transparent badge included with the I/O swag though, a URL for Google’s scavenger hunt would magically appear. [Travis] was intrigued by the effect, and became hell-bent on reproducing it himself.

[Travis] figured out the transparent badge was actually a polarizing filter. Every standard LCD has two of them, usually bonded to the glass of the LCD itself. If you remove the filters from a LCD, you’ll get a prime view of the backlight – unless you’re wearing polarizing glasses of course. Google’s monitors didn’t have that effect though. They showed a full color display, with a second full color hidden display only visible through the polarizer

It only took a bit of three-dimensional thinking for him to figure out Google’s trick. There are actually two LCDs used in the display. The first is a standard LCD with backlight. The trick is to strip the polarizing film off a second LCD and place it in front of the first. The second LCD will be invisible to anyone – without the polarizer.

[Travis] quickly set about replicating the display using several obsolete VGA LCDs. He quickly found that the hard part was peeling the polarizing plastic from the thin glass LCD sandwich. Several LCDs gave up their lives in the effort, but in the end [Travis] was successful. He made everything fit in one case by using a thin LED backlight in a case designed for a monitor with a Cold Cathode Fluorescent Lamp (CCFL). The result looks exactly like a standard LCD – that is, until viewed through a polarizing filter. Click past the break to see the hidden message LCD in action!

The Future Of Distraction, Right In Front Of Your Face

July 9, 2014 by Brian Benchoff 8 Comments

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.
