We were invited by Eric Pan from Seeedstudio (thanks Eric for the good time!). The Maker Faire has been a priceless experience to get in touch with the chinese maker community, as well as networking with different Chinese and Chinese-based maker companies creating interesting contents & products.
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 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:
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)
Come ogni anno, il 27 Ottobre 2012 si terrà in oltre 100 sedi in Italia il Linux Day, manifestazione nazionale di promozione al software libero open-source. Come non promuovere i fratelli maggiori?
Presso alcuni eventi si terranno talk e presentazioni su Arduino e il mondo dell’open-hardware: vi invitiamo a segnalarceli nei commenti a questo post, precisando luogo, ora e/o il link al sito di riferimento. Il sito ufficiale del Linux Day 2012 è: http://www.linuxday.it .
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.
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…

Many solutions exist for publishing data coming from Arduino boards on the web. Bangon Kali, 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:
The tutorial (which can be applied on Linux, Mac OS and Windows) can be found here.
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…
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.
