Desde BricoGeek nos llega la noticia de la celebración de una nueva Barcamp, esta vez en Vigo. La reunión perfecta para cacharrear y debatir entre amigos sobre temas como el Open Hardware, Arduino o impresoras 3D entre otros muchos, y puede que con alguna que otra sorpresa.
Unas jornadas DIY muy interesantes que tendrán lugar en las instalaciones del CFP Daniel Castelao de Vigo en las que Alejandro Taracido presentará a su mítico robot ORUGAS con las últimas novedades añadidas.
Sin duda, un evento al que no se debe faltar!
Planning preliminar (sujeto a cambios):
- Introducción al Open Harwdare
- Orugas: Robot explorador basado en Arduino
- Impresión 3D DIY. Crea objetos en tu casa
- Workshop BricoGeek
- Taller: DIY Soldadura SMD por refusión
- Taller: Medidas PWM analógicas
- Presentación proyecto RACE
- Raspberry PI como servidor FTP de contenidos

We are happy to announce the first wearable kit on the Arduino Store . This kit has been made by Plug’n’Wear specifically for us. All fabrics in this kit are produced in Italy, and strongly related to a textile family business. If you want to get deeper into the story of this product have a look at Riccardo Marchesi presentation (still in Italian, soon to be traslated!) at World Wide Rome 2012.

Loccioni Group, is an italian company that sponsors every year a project internship entitled “Classe Virtuale”, dedicated to young students coming from local technical schools.
This year, “Classe Virtuale 2012” has been composed by 27 students with different backgrounds, selected among 120 candidates. After a stating training period, during the three-weeks internship the team worked on a very nice Arduino-based project: Flow Meter.
Here you may find a brief interview we had with Daniele Caschera, one of the components of “Classe Virtuale 2012”, about Flow Meter and on how Arduino helped in its design.
This is a working model of an Arduino based Milling Machine created using FischerTechnik. For those of you who are unaware of FischerTechnik, it is similar to the LEGOTM Building Blocks.
A group of four Mechanical Engineering students at the Delft University of Technology (Netherlands) created this project as part of their Mechatronics class in their Second year of Bachelor of Sciences (B.Sc.) Program.
Laurens Valk, one of the creators, explains the essence of Arduino in the project:
“The system uses the Adafruit motor shield to run two stepper motors, and the Sparkfun EasyDriver for the third stepper motor. The Arduino runs code that listens to Matlab commands over USB. We expanded that code a little to make it possible to add the third stepper motor and some other commands. Most of the actual code was programmed in Matlab, with the Arduino as the interface between computer and motors/sensors.”
We had a little chat with Laurens. Here is the excerpt:
I’ve seen a lot of Arduino projects over the years, but this was the first time we used it in a project. Personally, I usually build robots with MINDSTORMS NXT, but this felt like a good opportunity to combine mechanical work (the printer hardware) with real electronics (Arduino).
We chose to come up with our own design challenge and decided not to do the standard exercise. Initially we thought about making a (2D) plotter or scanner. Then quickly we started thinking about the same things, except in 3D. One of the projects that inspired us was the LEGO Milling Machine by Arthur Sacek. Both a scanner and printer would still be doable in 3D, but the time was limited, so we settled with the printer idea.
All construction had to be done in one workweek for logistical reasons. To make sure we were able to finish in time, we prepared much of the electronics and software outside the lab. We finished just in time, but unfortunately we could do only one complete print before we had to take it apart. Not surprisingly, it was very exciting to wait for the result of the one and only complete test run. We couldn’t see the result until we used the vacuum cleaner to remove the dust.
Dr. Scott Ananian, from the One Laptop Per Child (OLPC) project, conceived an Arduino Leonardo-compatible board especially designed for the OLPC XO laptop, with the goal to cut down its price as much as possible, to foster its adoption even in developing countries. From Scott’s blog:
The board uses mostly through-hole parts, with one exception, and there are only 20 required components for the basic Arduino functionality, costing about $5 (from digikey, quantity 100). It is reasonable for local labor or even older kids to assemble by hand.
The board, named XOrduino, is open hardware (schematics and pcb files can be found on github), and can be directly plugged into the XO’s USB ports, which allowed Scott to save the money required for the USB connector. Moreover, its design has been inspired by other open hardware projects, such as SparkFun’s ATmega32U4 breakout board and SparkFun’s Scratch Sensor Board-compatible PicoBoard.
Scott designed also a second board, which is even cheaper than the first one, called XO Stick:
It’s based on the AVR Stick using the ATtiny85 processor and costs only $1/student. It’s not quite as user-friendly as the Arduino-compatible board, but it can also be used to teach simple lessons in embedded electronics.
It’s very exciting to see how open technologies, such as open hardware and open source software, contribute to the way education and creativity can take place around the world, especially regarding their promotion in developing countries.
