[Elvia Vasconcelos] developed a very simple yet interesting installation based on PureData and Arduino. The main goal is change / remix (and therefore innovate) the approach toward domestic appliances:
To re-purpose an object is to manipulate its construction. I believe there is nothing natural about the way objects behave and therefore in their potential to be reinvented. It is in the artistic domain to liberate these objects from the settings in which they have become predictable and accepted. For this installation I am looking at objects from the Home. I present a fan, an extractor, a light bulb and a vacuum cleaner that are pretending to be toasters. They are controlled by the viewer via a telephone. My work is guided by a desire to hold onto things but not exactly to hold them in place.
[Pierre] shares an interesting geo-localization project of sound, narration and culture, made in “plan d’Aou”, a district of Marseilles – France. The project dates back in September 2010, within the framework of the Smala project in order to trace a sound cartography of Islam in the city of Marseilles: the guys at [Echelle Inconnue] took their time to fully document the all project with schematics, codes, fritzing diagrams and so on.
Several mobile systems were distributed to the people to accompany their walk across the district with, by hand, a kind of speaker to be press on the walls which makes it possible to listen to the sound by vibrating the material of the wall.
The materials of urban furniture or buildings become the speakers required for sound diffusion. Each resonant body had its acoustic specificities, the words take shape in metal, wood or glass… Textures of the sound fluctuate from a surface to another and the listener must juggle with these characteristics to obtain a quality of optimal listening, between documentary in the walls and poetic sound creation.
[Alex Weber] put together a motorized drawing machine painting 2d Vector Graphics on his office’s glasses.
An automatic scribbling machine sounds less than useful, admittedly, but it’s really just the style of line created by this motorized drawing machine. It’s reminiscent of ASCII art, in which heavier characters are used to create darker tones; in this case, the more jiggle added to the drawing platform, the more ink is put on the drawing surface. It’s kind of mesmerizing.
Guys at [bildr] wrote a nice tutorial on how to control & use a thermal printer with Arduino.
Outputting data can be extremely useful, and typically when we look at doing this, it is either to the Arduino’s serial terminal, or to some sort of display. But what about making physical copies of the data? (…) If you dont know about thermal printers, they are most often the printers your store’s receipts are printed on. The reason for this is that they dont use ink, or use a cartridge of any sort. The paper it prints on turns black when heated. So this printer simply applies heat where another printer would apply ink.
[Tecnochicken] has challeneged his arduino and robotic skills in developing a tree-climbing robot based on a L298 H-Bridge Motor Driver and some design time in Sketchup.
After I got comfortable programming and building with an Arduino, I decided to build a robot. I did not have any particular type in mind, so I wracked my brain (and the internet) for cool robot ideas. Eventually, somehow the idea popped into my head to build a robot that could climb trees. At first I dismissed the idea as beyond my skill level, but after further thought, and some time in Sketchup, I decided to take a shot at the challenge.
Fully explained on [Instructables]
The Ben Heck Show, the DIY format on Revision3, explains and uses the Android Development Kit.
On this weeks The Ben Heck Show, Ben jumps right in to using the Android Accessory Development Kit and gets started on building a Baby Rocker that simulates vehicle motion from logged Android sensor data.
It’s amazing to see different efforts in building detailed instructions in using the board and the way this Arduino-to-Android device is changing the design for apps and physical interfaces. For more info check our ADK LABs page.
[Steve Hoefer] shared an interesting solution for visually impaired people.
It measures the distance to things and translates that into pressure on the wrist.[...] It’s wrist mounted and senses objects from about 1 inch (2 cm) to 10 feet (3.5m). It has generally fast response time (fractions of a second) to quickly navigate complex environments.
It’s not the first time we see Arduino used for custom solutions to navigate a room and / or enviroment, replacing the sight (above all, you’ll remember the [Bat Googles] project from USI and [Halo], the winner project of Humana competition).
“Tacit”, that’s how’s called this cool project, is the first in moving the sensitive response area of the device from the head (closed to the ears) to wrists (closed to the hands). Steve, whom its first prototype was conceived has an headband like the two projects above, moved its device to the wrist for several reasons
The headband was a great first test, and it did work, but it had two fatal flaws:
1) The most dangerous obstacles are not at head level. Furniture and most of the other things that can be tripped over and stubbed on are waist level or lower.
2) Vibrating motors stuck on your skull will drive you insane quickly.
In addition it would be a challenge to disguise it as anything but some mad-science-looking headband, and blind people do care how they look.
Tacit is wonderfully referenced and it’s realeased in CC-NC-SA
