Alexa And Particle Modernize Coffee Machine By One Iota

When [Steve Parker]’s girlfriend got a tea kettle that takes voice commands, he suddenly saw his fancy bean-to-cup coffee machine as a technological dinosaur. It may make good coffee, but getting the DeLonghi going is inconvenient, because it runs a self-cleaning cycle each time it’s turned on or off.

Thus began [Steve]’s adventure in trying to turn the thing on with Alexa via Particle Photon. Because of the way the machine is designed, simply adding a relay wouldn’t do—the machine would just turn off and back on, only to start the self-clean again. Once inside, he found it’s controlled by …read more

Alexa, Attack Intruders

If our doom at the hands of our robot overlords is coming, I for one welcome the chance to get a preview of how they might go about it. That’s the idea behind Project Icarus, an Alexa-enabled face-tracking Nerf turret. Designed by [Nick Engmann],  this impressive (or terrifying) project is built around a Nerf Vulcan, a foam dart firing machine gun mounted on a panning turret that is hidden behind a drop-down cabinet door. This is connected to a Pi Zero equipped with a Pi camera. The Zero is running OpenCV and Google Firebase, which connects it with Amazon’s Alexa …read more

Blueprints Make It Easy To Make (Some) Alexa Skills

If you can code, you can create an Alexa skill — the programs that allow an Amazon Echo or similar device interact with you. What if you can’t code or you are just too lazy to do all the setup? Amazon now has Blueprints that can help anyone make a skill. The only problem is the skills you can create are pretty limited. In addition, they are only available to your Alexa devices.

The idea is simple. You start with a template — OK, a blueprint. This is a model application that does something like giving you a compliment or …read more

Alexa Controls This Projector Thanks to ESP8266

[jfessard] doesn’t have extra-sensory perception, but does have an ESP8266. The little board seems to pop up in every hack these days. Inspired by not wanting to get up from the bean-bag chair or leave the electronics-housing cabinet wide open to use an HDMI switcher, [jfessard] hacked together an Alexa-compatible projector control via the ESP8266!

The core functionality here is the ability to turn the projector on and off, and to switch the HDMI source. [jfessard] connected the Panasonic PT-AE3000U projector to a Monoprice HDX-401TA 4×1 HDMI switcher. Tucked away in the cabinet below the projector, it is controlled using …read more

Have Alexa Open Your Garage Door

[yoyotechKnows] built an Alexa-controlled garage door opener after his Liftmaster stopped working. Now all he has to do is holler at his mobile phone and he can raise and lower his garage doors at will.

His project is based around a Photon WiFi kit, with a pair of LCC 120 digital relays triggering the two doors, reed switches, and a serial-equipped LCD to display door status, with Alexa, IFTTT, and OpenHab to process the commands. You can find his code in the project writeup.

Currently he has a LCD display informing him of the status of each door, hot glued …read more

Alexa, Sudo Read My Resistor! A Challenge for Hackers

Nothing makes us feel more like we’re on Star Trek then saying “Computer, turn on desk light,” and watching the light turn on. Of course, normal people would have left the wake up word as “Alexa,” but we like “Computer” even if it does make it hard to watch Star Trek episodes without the home automation going crazy.

There’s a lot of hype right now about how voice recognition and artificial intelligence (AI) are transforming everything. We’ve even seen a few high-profile types warning that AI is going to come alive and put us in the matrix or something. That …read more

Say Hello to This Cortana Hologram

Halo’s Cortana enters the real world with this internet appliance. [Jarem Archer] has built an amazing “holographic” home for Cortana of Halo and Windows fame. The display isn’t really a hologram, it uses the age-old Pepper’s ghost illusion. A monitor reflects onto 3 angled half mirrored panels. This creates a convincing 3D effect. Cortana herself is a 3D model. [Jarem’s] wife provided gave Cortana her moves by walking in front of dual Kinect depth-sensing cameras. This motion capture performance drives the 3D Cortana model on the screen.

The brain behind this hack is the standard Windows 10 Cortana voice assistant. …read more

The Internet Connected Dog Treat Machine

[Eric] and [Shirin] have a dog called [Pickles], who is the kind of animal that if you are a dog lover you will secretly covet. They evidently dote upon [Pickles], but face the problem that they can’t always be at home to express their appreciation of him. But rather than abandon him entirely, they’ve applied technology to the problem. [Eric] has built an Internet-connected dog treat dispenser, through which they can dispense treats, and watch the lucky mutt wolfing them down.

The body of the machine has been made with lasercut acrylic, and the dispenser mechanism is a rotating hopper …read more

That’s No Moon! That’s a Virtual Assistant

[Wisecracker] likes how the Amazon Echo Dot works, but he doesn’t like how they sound or how they resemble hockey pucks. A little 3D printing, though, and he transformed the Dot into a credible Death Star. That doesn’t sound very friendly, we guess, so he calls it Alex-Star.

What makes it work is the Death Star’s “superlaser” — the weapon operated by a console that looks suspiciously like some studio video equipment — happens to be about the size and shape of a two-inch speaker. [Wisecracker] added a slot to let the sound out of the second speaker. You can …read more

IoT-ify All Things: LG Has Gone Overboard

If you been following Hackaday lately, you’ve surely noticed an increased number of articles about IoT-ifying stuff. It’s a cool project to take something old (or new) and improve its connectivity, usually via WiFi, making it part of the Internet of Things. Several easy to use modules, in particular the ESP8266, are making a huge contribution to this trend. It’s satisfactory to see our homes with an ESP8266 in every light switch and outlet or to control our old stereo with our iPhone. It gives us a warm fuzzy feeling. And that’s completely fine for one’s personal projects.

But what …read more
