It’s often taken for grated, but the modern world is full of luxuries. Home automation, grocery delivery, and even access to the Internet are great tools to have at hand, but are trivial to most of us. If these modern wonders are not enough for you, and the lap of luxury is still missing a certain je ne sais quoi, allow us to introduce you to the ultimate convenience: a voice controlled, beer-dispensing sofa with a built-in refrigeration system.

This is a project from [Garage Avenger] and went through a number of iterations before reaching this level of polish. Metal work on the first version didn’t fit together as expected, and there were many attempts at actual refrigeration before settling on repurposing an actual refrigerator. With those things out of the way, he was able to get to the meat of a project. The couch-refrigerator holds 12 beers, and they are on a conveyor belt which automatically places the next beer onto the automated drawer. When commanded (by voice, app, or remote) the sofa opens the drawer so the occupant can grab one easily without having to move more than an arm. Everything, including the voice recognition module, is controlled by an Arduino, as is tradition.

The attention to detail is excellent as well. The remote control contains a built-in bottle opener, for one, there are backlights and a glass cover for the refrigerator, and the drawer is retracted automatically when it senses the beer has been obtained. We couldn’t ask for much more from our own couches, except maybe that they take us where we want to go. But maybe it’s best to keep these two couch use cases separate for now.

After being given a 2009 MacBook, John Forsyth decided to use it to start a 1976 Jeep via voice control.

The build uses the laptop’s Enhanced Dictation functionality to convert text into speech, and when a Python program receives the proper keywords, it sends an “H” character over serial to an Arduino Uno to activate the vehicle.

The Uno uses a transistor to control a 12V relay, which passes current to the Jeep’s starter solenoid. After a short delay, the MacBook then transmits an “L” command to have it release the relay, ready to do the job again when needed!

As a fan of Iron Man, Forsyth channeled his inner Tony Stark and even programmed the system to respond to “JARVIS, let’s get things going!”

[Diyguypt] may be an altruist to provide the means for people who can’t manipulate chess pieces to play the game. Or he may just have his hands too busy with food and drink to play. Either way, his voice command chessboard appears to work, although it has a lot of moving parts both figuratively and literally. You can check out the video below to see how it works.

The speech part is handled by an Android phone and uses Google’s voice services, so if you don’t want Google listening to your latest opening gambit, you’ll want to pass this one up. The phone uses an app that talks to the Arduino via Bluetooth, which means the Arduino needs a Bluetooth module.

The Arduino controls what amounts to an upside-down 3D printer. Instead of a hot end pointing down, the mechanism has an electromagnet pointing up. A small washer in the base of each chess piece makes it susceptible to the magnet’s motion. The electromagnet is required to let go of a piece before a move to a new position. It is possible that a small servo moving a permanent magnet closer to the board for a move and away from the board to reposition could do the same job, though we suspect that could be tricky.

We’ve seen this before, often with a Harry Potter theme. We sort of prefer a more obvious chess robot, but that’s just us.

Before going into the journalism program at Centennial College in Toronto, [Carolyn Pioro] was a trapeze performer. Unfortunately a mishap in 2005 ended her career as an aerialist when she severed her spinal cord,  leaving her paralyzed from the shoulders down. There’s plenty of options in the realm of speech-to-text technology which enables her to write on the computer, but when she tried to find a commercial offering which would let her point and shoot a DSLR camera with her voice, she came up empty.

[Taras Slawnych] heard about [Carolyn’s] need for special camera equipment and figured he had the experience to do something about it. With an Arduino and a couple of servos to drive the pan-tilt mechanism, he came up with a small device which Carolyn can now use to control a Canon camera mounted to an arm on her wheelchair. There’s still some room for improvement (notably, the focus can’t be controlled via voice currently), but even in this early form the gadget has caught the attention of Canon’s Canadian division.

With a lavalier microphone on the operator’s shirt, simple voice commands like “right” and “left” are picked up and interpreted by the Arduino inside the device’s 3D printed case. The Arduino then moves the appropriate servo motor a set number of degrees. This doesn’t allow for particularly fine-tuned positioning, but when combined with movements of the wheelchair itself, gives the user an acceptable level of control. [Taras] says the whole setup is powered off of the electric wheelchair’s 24 VDC batteries, with a step-down converter to get it to a safe voltage for the Arduino and servos.

As we’ve seen over the years, assistive technology is one of those areas where hackers seem to have a knack for making serious contribution’s to the lives of others (and occasionally even themselves). The highly personalized nature of many physical disabilities, with specific issues and needs often unique to the individual, can make it difficult to develop devices like this commercially. But as long as hackers are willing to donate their time and knowledge to creating bespoke assistive hardware, there’s still hope.

Are you still pushing buttons and adjusting knobs with your fingers to brew your favorite coffee? If so, then this voice-controlled solution could be the next project on your list.

To accomplish this hack, a rather high-end coffee maker was disassembled and modified, adding an Arduino Nano to press buttons, along with a small motor and driver board to adjust its dial. Voice control is provided via Snips software running on a Raspberry Pi, which passes the pertinent commands along for coffee making.

When the devices around you no longer require a lengthy operation manual, but rather, require only a voice command, this unlocks an environment where technology disappears into the background, so that you can regain the freedom to spend quality time with the people you care about. That is in fact our mission at Snips, to make technology disappear.

Case-in-point: this voice-activated coffee machine. You can ask it to make you a double espresso or a flat white, to pour you some hot water or even to turn itself off.

It’s purely a demo project, but at our Snips office in Paris, we’ve grown used to the convenience, and so we wanted to make it as easy as possible for anyone interested to replicate it at home.

Code and modification instructions are available on the Snips team’s blog post, while the brewing results can be seen in the demo video below.

It’s 2017 and even GoPro cameras now come with voice activation. Budding videographers, rest assured, nothing will look more professional than repeatedly yelling at your camera on a big shoot. Hackaday alumnus [Jeremy Cook] heard about this and instead of seeing an annoying gimmick, saw possibilities. Could they automate their GoPro using Arduino-spoken voice commands?

It’s an original way to do automation, for sure. In many ways, it makes sense – rather than mucking around with trying to make your own version of the GoPro mobile app (software written by surfers; horribly buggy) or official WiFi remote, stick with what you know. [Jeremy] decided to pair an Arduino Nano with the ISD1820 voice playback module. This was then combined with a servo-based panning fixture – [Jeremy] wants the GoPro to pan, take a photo, and repeat. The Arduino sets the servo position, then commands the ISD1820 to playback the voice command to take a picture, before rotating again.

[Jeremy] reports that it’s just a prototype at this stage, and works only inconsistently. This could perhaps be an issue of intelligibility of the recorded speech, or perhaps a volume issue. It’s hard to argue that a voice control system will ever be as robust as remote controlling a camera over WiFi, but it just goes to show – there’s never just one way to get the job done. We’ve seen people go deeper into GoPro hacking though – check out this comprehensive guide on how to pwn your GoPro.
