IoT Doorman: Eye-Controlled Door For A Girl With Cerebral Palsy

January 27, 2018 by 11 Comments

Kyleigh has an eye-controlled computer on her wheelchair but something as simple as her bedroom door was still beyond her reach… until now! [Bill Binko], recently filmed a demo of an automatic, IoT door opener built for the young girl with cerebral palsy. [Bill] is a co-founder of ATMakers, an organization that enables makers interested in assistive technologies to collaborate with users to improve quality of life.

Using her eye tracking tablet (PRC Device), Kyleigh has two new icons that make the relevant call to a website, pushing a simple command to either open or close her bedroom door. The device attached to the door uses an Adafruit M0 WiFi Feather board, a DC stepper motor and wheel, a UBEC buck converter, and a potentiometer.

Since other family members are also going to be opening and closing the door, there’s potentiometer which measures the door position for proper operation next time Kyleigh wishes to use the door. The installation also maintains a fairly inconspicuous profile for the assistance it gives — the ‘brain’ is enclosed in a small box on the door, with the motor only slightly larger on the door’s base.

[Bill] believes the project has a few quibbles and wants to work out a smaller wait before the open/close process is executed and optimizing the open/close speed. You have to check out the video below to see that it works really really. We’re also excited to see Kyleigh using her gaze control to talk to an Amazon Echo. [Bill] foresee a door control improvement that links it to Alexa. And how much did it cost to improve the quality of life for this young girl? $70.

We love seeing makers help people, and cannot wait to see what 2018 will bring! If you’re looking for more inspiration, don’t miss the eye-controlled wheelchair project called Eyedrivomatic which won the 2015 Hackaday Prize. There’s also the top Assistive Technology projects from the Hackaday Prize.

Teaching Alexa To 3D Print

January 5, 2018 by 21 Comments

Sometimes a gadget like Alexa or Google Home is a solution looking for a problem. Then the problem you’ve been looking for hits you square in the face. I’ve confessed before that I have an oscilloscope problem. I also have a microcontroller development board habit. It appears now I have too many 3D printers. I recently finished building my latest one, an Anet A8 I picked up on Black Friday. While calibrating it, I found myself juggling a screwdriver, a pair of pliers, and trying to operate the thing all at one time. I realized I had to come up with a better way.

I don’t know if it qualifies as an addiction yet, but I also have an Alexa in every room (although I call it “Computer” because I’m a Star Trek fan) and a Google Home device almost everywhere. Why can’t I get one of these assistants to operate my printer for me? What are assistants for, after all, other than telling Dad jokes?

You’d think adding voice control to a 3D printer would a bit difficult. With the right tools, it is actually pretty easy. Luckily those tools aren’t anything special… if you want a set up like mine, where Alexa controls your 3D printer, read on.

Robot: Do My Bidding!

July 11, 2017 by 6 Comments

Remote control robots are nothing new. Using Bluetooth isn’t all that unusual, either. What [SayantanM4] did was make a Bluetooth robot that accepts voice commands via his phone. The robot itself isn’t very remarkable. An Arduino and an HC05 module make up most of the electronics. A standard motor driver runs the two wheels.

The Arduino doesn’t usually do much voice processing, and the trick is–of course–in the phone application. BT Voice Control for Arduino is a free download that simply sends strings to a host computer via Bluetooth. If you say “Hello” into your phone, the robot receives *Hello# and that string could be processed by any computer that can receive Bluetooth data.

A Handy Tutorial For Voice-Command Awesomeness

December 9, 2016 by 9 Comments

When somebody can’t find a guide on how to accomplish a particular task, we here at Hackaday admire those individuals who take it upon themselves to write one for the benefit of others. Instructables user [PatrickD126] couldn’t find a write-up on how to connect Amazon’s Alexa service, and Echo to his Raspberry Pi home security system, so his handy tutorial should get you up to speed for your own projects.

[PatrickD126] shows how loading some software onto the Raspberry Pi is readily accomplished along with enabling Alexa to communicate more directly with the Pi. From there, it’s a matter of configuring your Amazon Web Services account with your preferred voice commands, as well as which GPIO pins you’d like to access. Done! [PatrickD126] notes that the instructions in the guide only result in a temporary solution, but suggests alternatives that would allow your project to operate long-term.

Talking Star Trek

June 8, 2016 by 34 Comments

Speech generation and recognition have come a long way. It wasn’t that long ago that we were in a breakfast place and endured 30 minutes of a teenaged girl screaming “CALL JUSTIN TAYLOR!” into her phone repeatedly, with no results. Now speech on phones is good enough you might never use the keyboard unless you want privacy. Every time we ask Google or Siri a question and get an answer it makes us feel like we are living in Star Trek.

[Smcameron] probably feels the same way. He’s been working on a Star Trek-inspired bridge simulator called “Space Nerds in Space” for some time. He decided to test out the current state of Linux speech support by adding speech commands and response to it. You can see the results in the video below.

Echo, Meet Mycroft

September 23, 2015 by 50 Comments

The Amazon Echo is an attempt to usher in a new product category. A box that listens to you and obeys your wishes. Sort of like Siri or Google Now for your house. Kickstarter creator [Joshua Montgomery] likes the idea, but he wants to do it all Open Source with a Raspberry Pi and an Arduino.

The Kickstarter (which reached its funding goal earlier this month) claims the device will use natural language to access media, control IoT devices, and will be open both for hardware and software hacking. The Kickstarter page says that Mycroft has partnerships with Lucid and Canonical (the people behind Ubuntu). In addition, they have added stretch goals to add computer vision and Linux desktop control to Mycroft.

Talk To The (Robotic) Hand

July 19, 2015 by 1 Comment

Robotic hacker [Andrea Trufini] apparently likes choices. Not only does his robotic arm have six degrees of freedom, but it has a variety of ways he can control it. The arm’s software can accept commands through a programming language, via potentiometers, an infrared remote, or–the really interesting part–through spoken commands.

The videos don’t show too much of the build detail, but the arm is mainly constructed of laser cut plywood and uses an Arduino. Hopefully, we’ll see more particulars about the build soon but for now have a look at a similar project.

The software (myrobotlab) is on github and looks very impressive. The Java-based framework has a service-oriented architecture, with modules that support common processors (like the Arduino, Raspberry Pi, and Beagle Board) along with I/O devices (like motors, sound devices, and that Leap Motion controller you just had to buy). As you might expect from the demonstration found below, there are speech to text and text to speech services, too. Like a lot of open source projects, some of these services are more ready for prime time than others but that just means you can contribute your hacks back to the project.
