Ikazoo, a multifunctional entertainment device for music and more

Friday, March 29th, 2013

ikazoo

iKazoo  is a prototype for an open source platform using Arduino and  recently launched a crowdfunding campaign on Indiegogo.  It’s a multifunctional device assistant for entertainment with a  touch and shock sensitive surface. It can easily record or alter your voice but also play many types of instrument.  You can use it as a optical game controller and even as a brush on your pad. The hardware  contains sensors that can monitor all body movements and become a step counter.  Here’s the video presentation:

Bleuette, the hexapod robot

Monday, March 18th, 2013

bleuette hexapod robot

Bleuette project is hexapod robot equipped with 6 legs that can be operated without any external guidance.

The french project is fully open hardware (made entirely with  an Ultimaker 3D printer) / opensource and operates on a Arduino Leonardo board with a custom shield developed for it and available on Hugo’s website, the author of the project. It is used mostly to control the 12 servos (+ 2 optional) for the legs, measure voltage and current.

Take a look at the robot’s first steps!

 

Hugo is also thinking about future developments for Bleuette, like equipping it with a Bluetooth connection, a magnetic sensor to keep an edge when walking and finally a mobile turret with an ultrasonic sensor to detect obstacles in front of it.

Interested in the code? you can find it on Github:

The Coming Civil War over General Purpose Computing

Tuesday, October 30th, 2012

This enlightening article (talk) by Cory Doctorow appeared on BoingBoing last August. This is not (only) a must-read in terms of  imaging our near future, but an interesting way to weight the importance of the moral meaning Open Source Hardware has in real terms. Happy reading (or listening)

Time-based OTP with Arduino

Monday, July 16th, 2012

First prototype

One-time-password (OTP) and its time-based version (time-based OTP, or simply TOTP) are commodity solutions to provide a second factor, in addition to simple passwords, for authentication.

Here Jose Damico proposes his way to implement a simple TOTP device using only open-source tools. The core of the project is an Arduino board connected to a small LCD. From the software perspective, the SHA-1 library comes from Cryptosuite, a cryptographic library for Arduino.

The device, which is OATH-compliant, will be presented soon to the “13th Fórum Internacional Software Livre“, that will be held in Porto Alegre, Brazil, in next July 25-28.

Arduteka - Arduino Barcamp Zaragoza 2012

 

Arduteka en colaboración con Cooking Hacks y Milla Digital del ayuntamiento de Zaragoza han preparado un evento con capacidad para más de 400 personas en uno de los edificios más emblemáticos de la ciudad, el Antiguo Seminario Metropolitano de Zaragoza transformando en una moderna Ciudad Administrativa Municipal y que amablemente han cedido para organizar el evento.

 

Desde charlas sobre arte interactivo con Arduino como interface, pasando por talleres sobre impresión 3D hasta demostración de integración de Arduino con Asterisk será solo una parte de lo que vamos a poder disfrutar, ya que estarán habilitados diferentes Stands como el de Parrot, en que podremos probar el nuevo Ar-Drone 2.0, el de Cooking Hacks que nos amenizarán con micro talleres Arduino e incluso el de nuestros amigos de Ultra-Lab que seguro hará las delicias de los asistentes.

 

Por si esto fuera poco.. Contaremos con la presencia y colaboración de David Cuartielles, el cual nos ofrecerá una charla sobre los últimos productos Arduino que se está aconteciendo…

 

Accede ahora a toda la información en la nueva web de Arduteka AQUÍ e inscríbete!!

Publishing data on the web with Node.JS

Tuesday, June 5th, 2012

Many solutions exist for publishing data coming from Arduino boards on the web. , in his detailed tutorial, proposes his novel approach, which makes use of several widespread and open-source technologies, such as Node.JS, jQuery and Apache:

Using the USB, the Arduino Board is connected to the PC serially to a certain COM port which the OS allocates. Node.JS, the asynchronous server side JavaScript engine then listens for the port using a Node.JS module called SerialPort2. When a signal is received, using the Node.JS Socket.IO module, data is then served also asynchronously to the web providing a real time feed of the Arduino signal.

The tutorial (which can be applied on Linux, Mac OS and Windows) can be found here.

Arduino, GPS and Display i2C…

Friday, May 25th, 2012

 

En este nuevo tutorial Arduino by ARDUTEKA, estudiamos a fondo los módulos GPS, en concreto los módulos diseñados por LIBELIUM, para aprender a extraer y comprender todas las tramadas de datos que recibimos de los GPS y posteriormente, tratar esa información para mostrar en un display con bus i2C datos como la latitud, longitud, altura y hora UTC…

UnoJoy – A USB Joystick for Mac, PC, Linux or PS3

Monday, May 14th, 2012

There are people who use the Arduino for some serious electronics related stuff.

Then, there are folks who use it just for fun. Alan Chatham and his team over at UnoJoy have developed a concept for Arduino Uno based USB Controllers.

 

 

Here is an excerpt of our interview with Alan:

Me: What made you choose the Arduino Uno as the heart of the controller? There are many development boards available which incorporate an ATmega8U2/16U2 or even 32U2.

Alan: This is easy – everyone loves Arduino!  It comes down to ease of use and reach.  Our primary goal with this project is to make a tool that is both easy to use and accessible.  There’s lots of code out there to make joysticks with other chips, but all the Atmel USB chips are surface-mount, and they all need a whole big toolchain to use. Plus, USB is super-complicated, and we want to encourage people, even non-technical ones, to spend their time thinking up really sweet new ways to play games, not trying to figure out what an HID descriptor is for.  On the reach side of things, Arduino is a perfect platform – even those of us that love our inline assembly and fuse settings tend to have an Arduino around for quick prototyping, and of course, Arduino’s a great platform for students and designers.

 

Me: Any problems that you faced while developing the prototype?

Alan: I think the biggest challenge we faced was to make it much easier for non-experts to do some more complicated things, like re-flash the ATmega8u2 on the Arduino. Let’s face it, any instructions that open up with ‘First, install XCode’ aren’t exactly user-friendly. In that vein, I put together some simple one-click batch files for installing the appropriate drivers on Windows and OSX, as well as ones for reflashing the ATmega8u2 chip between Arduino and UnoJoy firmwares.  It’s still not as simple as I’d like, so if anyone out there is handy with basic OSX GUI application programming, or the program installation chain on Windows, drop me a line!

In the end, we’re hoping that our code and examples can inspire other designers and builders and gamers to make some really awesome controllers. If they do, I of course encourage them to send their pictures and videos our way, at unojoy.tumblr.com!

Now, you too can make yourself a USB Joystick/ Gamepad/ Controller by choosing any form of input that the Arduino boards can understand. The source code and all the necessary download files are available at Google Code. Don’t forget to check out the Controller for Gran Turismo:

 

 

Thank you Alan for sharing a wonderful project with us.

Directional shoes for the blind

Le-chal from Anirudh's presentation

Sometimes, it is amazing to see how technology is used to make the world a better place to live for the less fortunate. One such problem has been thought out and tackled by Anirudh Sharma aka touchaddict on IRC. His invention is called ‘Le-chal’ which translates to ‘Take me there’ in Hindi.

Sharma conceptualized and demonstrated the system at MIT (Massachusetts Institute of Technology) Media Lab Design and Innovation Workshop 2011.

The Le Chal system comprises of a pair of shoes, one of which is fitted with Vibrators, proximity sensors and a Bluetooth pad which is connected to an Android phone that calculates directions and real time location using Google Maps and the phone’s built-in GPS and compass module.

For all the people calling Arduino a ‘toy’ and ‘too simple’ here is a fact: it’s simplicity gave the inventors the power to rapidly prototype, and the invention was ready in 6 days.

As per his presentation, the system costs barely a few hundred rupees to assemble with 8 mini vibrational motors costing Rs 90, a sole of specified dimensions, an Arduino Lilypad GSM+GPS shield custom made for Rs 400 or a wired version costing Rs 150 for all the components.

The shoes have also been tested at a blind school in Bangalore, India, and have received positive reviews.
