SitioMovil. IOIO for Android. Meet IOIO - I/O for Android. I'm very excited to announce the launch of a new product I've been working on for the past months! IOIO (pronounced: yo-yo) is a product which lets you connect electronic circuits to an Android device and control them from an Android application. It is comprised of a small (2.7x1.2" = 7x3cm) PCB that connects to an Android device with a USB cable and a software library (Java .jar file) that you use in your Android app which handles all communications with the board.No firmware programming is required - only Android application authoring with a very simple API (see examples below) for controlling the pins on the board. No modification of the Android device is required - you avoid the complication of modification and the voiding of warranty.IOIO is available for purchase online from SparkFun on this page.

The first few boards will ship within a couple of weeks. The Retroid The Retroid is a retro-designed alarm clock hacked to be controlled by an Android phone. The Visual Charger. The MEDEA approach to co-production research methodology. In Medea, co-production is a given when it comes to planning the research processes of knowledge construction. We find this to be a favorable premise, in general terms for asserting relevance and ecological validity, as well as specifically for addressing the collaborative nature of the new media. However, some general methodological considerations must be noted that follow from a strict co-production approach to scientific research. This page was created on Apr 20, 2010, and last revised on Feb 4, 2011. First, co-production research involving academic researchers in collaboration with external partners always entails the integration of multiple agendas.

Moreover, the researchers and partners bring complementary sets of expertise to the co-production table. The interventionist aspect of action research leads on to design research (Archer 1981, Cross 1999, Roth 1999, Nelson and Stolterman 2003), which is the second methodological cornerstone of co-production research processes.

While Lawnmower Man may have led us to believe the future was a virtual one, it seems that in fact augmented reality (the overlaying of digital data on the real world) is where we're headed. A buzz technology right now, augmented reality apps are quickly gaining momentum on the iPhone. So to add to the quick overview of six AR apps we brought you earlier, we sort the digital wheat from the pixellated chaff to bring you ten AR apps for the iPhone that vary from functional, to educational, to just plain fun. 1. Le Bar Guide Although the wisdom of getting drunk people to wave their iPhones around on today's mean streets is questionable, if you drink responsibly, as this Stella Artois-backed app urges you to, this could be a handy tool. 2.

Another corporate-backed app, this time by Plantronics, is WorkSnug, an iPhone app that finds digital nomads a place to lay their weary laptop. 3.

MAT 594O - Sensors and Interfaces for Media Art (Winter, 2010) MAT 594O - Sensors and Interfaces for Media Art (Winter, 2010) Overview The MAT Sensors and Interfaces course explores the use of multimedia sensor technologies and embedded microcontroller systems for interactive environments/installations and responsive artwork/performance systems. We will start with an introduction to the theories of space in art and human-computer interaction (HCI), and proceed to an in-depth analysis of current art-HCI technologies.

Students will acquire experience that will allow them to research and develop custom sensor systems in their own work. The course will introduce the principles and operation of many sensor techniques and discuss applications in gestural human-computer interfaces, new musical instruments, the visual and spatial arts, engineering, science, and other areas of interest.

It will cover the design of computer interface systems including analog/digital electronics and human factors/interaction styles. Course Topics Instructors Stephen T. RobotShop. PWM and Arduino: fading an LED and playing melodies on a Piezo Speaker. Submitted by fabio on Mon, 2010-07-26 12:49. In the past blog posts, we already saw how to read and write digital signals on the Digital Input Output pins of the Arduino. We also used the analog reading capabilities of Arduino to read values from variable resistance components such as potentiometers, thermistors, or LDRs. We still don't know anything about how to produce an Analog Output signal with Arduino. In this post, will cover it. Pulse Width Modulation (PWM): analog outputs with digital means Digital boards and processors, like the Arduino board and its ATMega 328 microcontroller, usually have some problems providing an Analog Output, a variable signal which can range from eg 0 to 5V.

Fortunately, there is the Pulse Width Modulation or PWM technique which permits getting an analog result using digital means. The Arduino PWM tutorial describes how PWM works: Digital control is used to create a square wave, a signal switched between on and off. This is what it produce: Here is the code:
