Many products and services requires interactions today and it has been a big challenge for designers in how to sketch ideas. Sketching on paper will not describe your idea any more as you need to illustrate experiences. This course teaches you various techniques of how you can sketch experiences by making functional prototypes. The prototype can be from wearable objects to installations. The course will provide easy-to-use and quick-to-make tools and materials. You will form groups and develop ideas based on a given theme. The groups iterate their designs through prototyping. The final prototype should be presented at Media Lab Demoday in May.
You can find student work in previous years as follows.
It is fun to play with kites in Helsinki since there is a good wind current during most part of the year. For this course it was considered to add a value for kites with electronic features, in other words, to produce a sonification of kite movement. Thus the kite works as an interface to generate data to produce sound on real time, an instrument for musical or sound art performance which is controlled manually and modified randomly by wind conditions.
The interface has a wireless system that measure the speed and rotation of the kite, thus this data is transformed into sound on real time. Sound modules are designed upon on the principles of composition with pulsars, developed by Curtis Roads, and the micro sound studies of Alberto de Campo. For future development is considered to include a dynamic led light system and increase the number of simultaneous kites. Here is some pictures of the process of creation of the kite, and electronic devices used for the project.

Finally this project was presented in Voda Helsinki a visual arts, literature and music event in Kalasataman Aukio, on sunday 19th august 2012.
DS3234 is also a real time clock IC. It uses SPI to communicate while DS1307 does with I2C. There is a Arduino library for DS3234 to provide simple methods to set and read time. You can purchase DeadOn DS3234 RTC Breakout from Sparkfun.
DS1307 Real time clock can tell time to Arduino. You can turn off Arduino as a small button battery is attached to the DS1307. Once you set the right time on the DS1307, it can keep ticking up to 7 years.
TLC 5940 PWM driver can control up to 16 LEDs. You can dim each LED separately. It also allows to cascade multiple TLC 5940 PWM driver thus you can have more than 16 LEDs multiplied with the IC. As I need 60 LEDs, I am cascading 4 of them. As I understand, it communicates with SPI with a couple of additional wires. There is a Arduino library for TLC5940 which comes with good example sketches. I have attached basic schematic and Arduino code to test multiple TLC5940.
There are two ways to connect Android to Arduino over USB. They are Android Debug Bridge Mode (ADB) and Accessory Mode (ADK). ADK supports only newer Android than 2.3.4 while ADB supports even older than 2.2. A demo in this page uses ADB.
