[Justin]’s friend [Steve] injured his spine a while ago, and after asking what would make [Steve]’s life simpler, the answer was easy. [Steve] missed reading books. Sure, e-readers exist, but you still need to turn the page. Now [Steve] can do that with his voice thanks to some microcontrollers, Bluetooth modules, and a voice recognition module.
A voice-activated page turner wasn’t the first attempt at giving [Steve] the ability to turn a page on a Kindle. The first prototype was a big blue button that sent a keyboard code for ‘right arrow’ over Bluetooth, turning a book one page at a time. This worked well until multiple pages turned, and with no back button it was a major nuisance.
After playing with the voice recognition in an Amazon Echo, [Steve] and [Justin] wondered if the same voice recognition technology could be applied to page turns on a Kindle. With a voice recognition Arduino shield from SparkFun it was easy to detect a ‘page down’ command. A Bluetooth module sends HID commands to a Kindle, allowing [Steve] to read a book with only his voice.
[Justin] put all the design files for this build up on Github.
Tony Stark’s J.A.R.V.I.S. needs no introduction. With [Shubhro’s] and [Charlie’s] recent release of Jasper, an always on voice-controlled development platform for the Raspberry Pi, you too can start making your own J.A.R.V.I.S..
Both [Shubhro] and [Charlie] are undergraduate students at Princeton University, and decided to make their voice-controlled project open-source (code is available on GitHub). Jasper is build on inexpensive off-the-shelf hardware, making it very simple to get started. All you really need is an internet connected Raspberry Pi with a microphone and speaker. Simply install Jasper, and get started using the built in functionality that allows you to interface with Spotify, Facebook, Gmail, knock knock jokes, and more. Be sure to check out the demo video after break!
With the easy to use developer API, you can integrate Jasper into any of your existing Raspberry Pi projects with little effort. We could see Jasper integrated with wireless microphones and speakers to enable advanced voice control from anywhere in your home. What a great project! Thanks to both [Shubhro] and [Charlie] for making this open-source.

The race is on to squeeze cycles out of an 8MHz AVR chip in order to better drive the WS2811 LED protocol.
[Asher] doesn’t want to buy charcoal aquarium filters if he can just build them himself. He filled a couple of plastic drink bottles with charcoal, cut slots in the sides, and hooked them up to his pump system. A gallery of his work is available after the break.
Is the best way to make microscopic sized batteries to 3d print them? Harvard researchers think so. [Thanks Jonathan and Itay]
The Ouya gaming console is now available for the general public. [Hunter Davis] reports that the Retrode works with Ouya out-of-the-box. If you don’t remember hearing about it, Retrode reads your original cartridge ROMs for use with emulators.
Making a cluster computer out of 300 Raspberry Pi boards sounds like a nightmare. Organization is the key to this project.
Hackaday alum [Jeremy Cook] is working on an animatronic cigar box. Here he’s demonstrating it’s ability to listen for voice commands.
A Kelvin clips is a type of crocodile clip that has the two jaws insulated from each other. [Kaushlesh] came up with a way to turn them into tweezer probes.

It’s entirely possible to use a computer without the aid of a mouse or trackpad. Shift and arrow keys will get you very far, but that is entirely too taxing. [Stephen] came up with a really neat way to control a mouse with your voice, a project that is sure to find its way onto the desktops of those with mobility issues very quickly
The voice controlled mouse works in conjunction with the voice recognition built into OS X, a little AppleScript, and a touch of Python. When the user says, ‘show grid’ a 10 by 10 grid numbered 1 to 100 is displayed on the screen. By saying ‘thirty five,’ the cursor moves to the 35th cell in the grid. From there, the mouse can be controlled by speaking cardinal directions such as South and Northwest.
[Stephen] put up a very clever demo of his Voice Mouse project available after the break. Even though he did have a little difficulty with his mac recognizing a few of his spoken commands its light years ahead of trying to navigate the web with just shift and arrow keys.

[Joseph] wrote in to share this home automation system he’s working on as a college project. He calls it the Room Engine and the house-side of the hardware is built on top of the circuit you see here. This is the most basic part of the REBoard, which is meant to connect to a computer uses RS232 or USB, and in turn use a set of relays to switch mains voltage devices.
You can follow the bread crumb on his webpage to get a broader video of the system. The interface is designed to use two parts. One is a voice recognition system that is supported by the computer. The other is an iOS interface that includes login credentials and a button-based control system. The video after the break shows off the smart phone portion of the controller. We think he’s done a good job of integrating a few appliances without the need for commercial products such as X10 modules.
If you’re just interested in switching a few things without cord’s reach of each other this can get it done, and offers scheduling functionality. It would also be pretty easy to set this up with a WiFi module and do away with the PC.

A Remote Sphero-Control Trackball
Sphero is a cool little ball that can roll around under the control of a smartphone. Although super-cool by itself, in this application it’s been hacked into a sort of trackball to drive a remote control car!
Arduino Voice Control
[Sebastian] Wrote in to tell us about this article about using the Arduino EasyVR shield to add voice control to your project. Worth a look if it your application calls for voice-control.
OpenBeam Tiny 80/20-Like Extrusion
Openbeam is a Kickstarter project designed to produce an aluminium extrusion for building stuff. Although we’ve seen lots of this kind of thing, the small 15mm profile is quite interesting, and it’s designed to use off-the-shelf hardware, which should save on costs!
Hexapod + iPad = Fun for All
There’s not a lot of information on this hack, and the price or this hexapod device isn’t even listed, so we’ll assume it’s quite expensive. On the other hand, it’s got a cool video of it being controlled by an iPad, so maybe it will give you some hacking inspiration!
USB Sound Card Write-Up
[George] wrote in to tell us about his USB sound card write-up. Before you think that this is a dupe of this post, he freely admits to building it nearly identically to the one previously posted. Imitation may be the sincerest form of flattery, but [George] is also requesting some feedback on his blog and the aforementioned post. feel free to let him know what you think in the comments. Please be polite!
[Arthur] was laid up with a wrist injury, so he decided it would be a great time to hang out around the house and tinker with electronics, since most outdoor activities were out of the question. He picked up a robotic arm kit and assembled it to test out some code written for it that he found online. Since typing commands into a terminal was awfully cumbersome considering his injury, he figured he might as well construct a voice control system for the arm.
He documents his work in a three part series, covering the process from concept to completion. The first part centers around the creation of the vocabulary and grammar for the voice recognition system, along with the how the grammar model was trained using voice samples.
The second and third portions of his tutorial deal with the software’s decoding of his commands and the Python scripts used to translate those commands into something the robotic arm can process.
[Arthur’s] voice control system works pretty well as you can see in the video below, though he already has a wish list full of improvements he hopes to make in the near future.
