Interview With David Cuartielles About Open Hardware (in Spanish)

Monday, March 21st, 2011

For the many spanish-speaking readers of the blog, an interview with David Cuartielles, explaining Arduino and its “silent revolution”:

Arduino es el Hardware Abierto —o Libre, como gusten— por excelencia y David Cuartielles su co-creador. Él, junto Massimo Banzi y un creciente grupo de hackers de la electrónica y el software han diseñado y construido no sólo un dispositivo físico con espíritu libre y abierto, también han guiado una gran comunidad de entusiastas en lo que Soraya Paniagua recién llamó una “revolución silenciosa”.

The BodySuit and the Swedish Crown Princess

Friday, March 18th, 2011

Last week, Victoria -the Swedish Crown Princess- and Daniel -her husband- came by Malmo University and visited the Medea Research Facility. There was a talk about New Media and the importance of the research made in the field in order to identify new business opportunities, as well as promote freedom of speech.  There were four projects presented to the Royal couple, all coming from different initiatives related to the activities at Medea.

One of the projects, made by PhD candidate Mads Hobye, is a BodySuit he made for Burning Man that measures body resistance and responds with interesting sound patterns. It becomes some sort of communication enhancer. The BodySuit was prototyped using an Arduino, two sets of headphones, some LEDs and a lot of creativity. I know the code he used for generating the sound was made by a friend of his … you should try to get that code, it is worth every byte.

Build “An Interactive Exhibit for About $30″ With Arduino, Online NYT Word

Thursday, March 17th, 2011

[Nick Bilton] published an article about Arduino and how it influenced Interaction Design, with a close look about Exhibition Design.

“The Arduino has changed the way we can create and build exhibits,” said Hélène Alonso, director of interactive exhibits at the American Museum of Natural History in New York. “In the past, we would have used 50 percent of our budget on computers that have now been replaced with the simplicity of the Arduino.”

A current exhibit at the museum called “Brain: The Inside Story,” uses an Arduino to calculate a person’s accuracy and brain power while tracing the shape of a star. Another exhibit at the museum lets people see the relationship of the weights of some dinosaurs in relation to those of humans.

For artists and designers, one of the biggest draws of the Arduino is the cost. A single Arduino, which can be used to control a number of aspects of a museum installation, costs just $30. Once an artist has a chip, inexpensive sensors can be added to make the device sentient.

Arduino and NanoNote put together

Monday, March 14th, 2011

David Reyes, aka Tuxbrain, one of the Arduino distributors in Spain, has just brought to life one of the coolest hacks I have seen for some time. He managed to reflash Arduino Uno from a Ben NanoNote. He has implemented a text-based IDE that can reflash the boards directly from the NanoNote without using external power. If you want to have a device to reprogram your ATmega processors without having to bring your computer around, this can be a great solution. Just remember, this is an advanced hack, you should be familiar to the use of CLI (Command Line Interface), but David has promised taking a look at Qt-creator and put together a small text editor with uploading capabilities. Stay tuned at Tuxbrain’s development website!

On Tuxbrain, thanks to the Qi-HardwareAVRFreaks communities and to the little UBB board, we have successfully flash an Arduino board from Ben NanoNote without need of external power, directly connecting a cable from the NanoNote 8:10 bay to the ICSP header on Arduino, also without need of bootloader in the Atmega328 chip, in fact NanoNote can flash the bootloaders :) , and in theory Nanonote can flash whatever  avrdude compatible chip without need of any board (untested yet). Making the little Ben the first AVR microcontroller programmer in the world able to edit the source code, building it, listen music or play Supertux at same time, in same device, not bad for only 99€ ;)

 

Master of Advanced Studies in Interaction Design in Lugano, Switzerland

Monday, March 14th, 2011

Arduino is partnering with SUPSI (the University of Applied Sciences and Arts of Southern Switzerland) to collaborate on the Master of Advanced Studies in Interaction Design:
Students applying for this program will attend courses on physical computing and interaction design held by co-founders of the Arduino project such as Massimo Banzi; furthermore, they will have the opportunity to develop the master thesis in collaboration with Arduino and spend a whole term working with the Arduino platform in order to create innovative projects.

Cheap Thermocam Around 100$

Monday, March 14th, 2011

[Max] forwarded me an impressive project about a DIY Themal Camera. The overall cost for building it is around 104$, compairing to professional products ranging from from 2000$ to 30.000$.

after some time of research I want to present my latest project called “Cheap-Thermocam”. It enables to create thermal images of houses, electrical devices or other things. An infrared sensor is mounted on two servos for moving it up/down – left/right. For an optical image of the scanned area, a webcam is installed under the sensor. An easy to install computer software written in JAVA shows a preview of the webcam image and then collects all the temperature data neccessarry to create the thermal image. To do this, 1344 single points are measured in about 2 minutes, this is a rare resolution of 42×32 Pixels. The advantage of my project compared to commercial thermal cameras is obviously the price. Another positive aspect is that the pictures can be analysed and edited with my easy to use pc software. The whole project can be built in 2-3 hours without any difficult parts do be soldered.

Related Arduino projects about this theme can be seen here (DIY Thermal Imaging System for under $200) and here (Thermoscanner).  All Codes are provided

Illutron Ship Gets Remote-Controlled

Friday, March 11th, 2011

[Christian] from Illutron hackespace in Copenhagen managed to control and monitor this ship (Illutron) from the internet.

Today, it is finally possible to remotely monitor the ship. In essence: I am sitting in the warm comfort of my home, and with a glance at my phone, I can see, that the sinking alarm in the machinery room is dry. The light is out in the Mess room. All is nice at our little lovely ship out there in the dark, cold Sydhavn.
Actually, behind this lies a pretty clever system (I think I am allowed to brag a little :-) , that makes it possible to monitor events on sensors on the ship, and trigger that messages is sent to Google
Talk users. (if you have a gmail, you have Google Talk) It is also possible via your chat, to send commands to the ship, and get reading from sensors when you want them.[...] Basicly, we can monitor anything, that can be plugged into an Arduino board. One thing I would love, is a temperature sensor for the Mess room. Bring the sensor, and I will mount it So far, we have
– a light sensor, that reports if it is light or dark in the Mess (the electronics room)
– a new water level sensor. I didn’t dare mess with the old system, so I am putting in new float sensors

Things can still be developed a lot, and it will be – Suggestions would be happily received.
Thanks and hello to Stephane and Olle that came by to visit us at the sunday meeting, and ended up staying all evening – for help with sensor mounting and JavaScript improvements!

Have a look at this Ship Automation project on [Christian Liljedahl project page] and [Illutron site]

We are looking for Forum Moderators

Friday, March 11th, 2011

Updating the forum has been one of our best investments so far. The communication flow has increased dramatically (I will post about this soon, including some graphs) but also the need to headhunt community members to give a hand in making the forum and the web the best resource possible for Arduino interested people and related initiatives.

Please take a look at this post: http://arduino.cc/forum/index.php/topic,54857.0.html and put your name at the bottom if you want to become one of our moderators. We will choose people based on their experience and contribution.

Not Designed To Be Dumped

Thursday, March 10th, 2011

Arduino itself is something used to do things (or repair / reuse them). It’s very difficoult for you to break it, and it’s not the kind of consumer electronics product depicted in the video above (I must say me myself I’m treated like a kind of dump by my friends: people brings me all kind of electronic junk in order to be reused. I think this is common to most of our readers). But still I find this video strongly related to DIY world, our way to design things,  our personal daily habits. We strongly advice you to spend your next 7’46” in watchin this video.

(by the way,  long ago Arduino opted for Carbon Neutrality for the majority of its products).

Must-See Beginner Tutorials For Arduino

Wednesday, March 9th, 2011

[Jeremy] made ten Tutorials about Arduino worth our “All Stars” category. He talks about different themes: Blinking Leds [Intro & #2], Electrical Engineering  [#3],  Analog Inputs [#4], Motors & Transistors [#5], Serial Communication & Processing [#6], I2C & Processing [#7], SPI Interfaces [#8], Wireless Communication [#9] and Interrupts [#10].

Thanks to a generous sponsorship from element14, I’m putting together a tutorial series on using the arduino microcontroller platform!  The arduino is a platform that I’ve done several projects with, and I think it is the best possible way for beginners to get acquainted with electronics.  This tutorial series will be aimed at beginner users, but I’m hoping to keep it going with some more advanced topics a few episodes into the future.

thanks Jeremy! ++
