    Things what we did that day:

    • Built a level shifter.
    • Built hardware connections between sensors and level sifter.
    • Improved user interface by changing the size and colors of some parts (eg. buoy). Uploaded the image in the tablet and testing it outside in the environment.

    Problems what we faced:

    • In the software Arduino part a problem raised at the NMEA/TinyGPS library, because the library does not include ready functions for extracting wind information
      such as direction and speed. Due to that problem Arduino will not be responsible for analyzing and parsing the NMEA strings in C language, but the tablet will
      take this responsibility and this task will be completed using Java programming language.

    Things what we plan to do:

    • Fix our main problem to get information from arduino controller.

    Things what we did that day:

    • On the hardware section some faults were repaired. We changed the baud rate of the information extraction, and by that action the laptop device that was
      connected to the server was able to identify the NMEA protocol strings from the server. Also with an Oscilloscope we checked that the outcome signal of the system is correct.
    • A prototype program was created that a tablet controls the led of the arduino controller with a tap of a button.

    Problems what we faced:

    • Faults in hardware connections, faults with the level shifter.
    • Just problems with java developing, can't say in more details.

    Summary of what we did and solution what we developed

    Personal Input

    • Konstantinos Verigos

    As team leader of this team i was responsible for everyday meetings, everyday task assigments and everyday problem solving. As a member of this team i analysed the description and researched solutions with my team for this project. I was assigned the programming aspects of this project. Programming the arduino microcontroller with the android shield and developping the android application for our 10inch tablet.

    What I learnt:

    • Tommi Potapoff

    All the information is based on data, we are getting out of our sensors (wind, gps, speed). I had to find out how to connect all the Nexus components and set the settings. It took a lot of time to get familiar with manuals and get the system up and running. Because of different voltage levels, I had to build a level shifter that we could connect Arduino to our Nexus system. NX2 server's +/- 12V was converted to +0-5V. To Arduino I connected all the hardware buttons that we used in prototype. To connect Arduino and Android together, needed we the Android shield on Arduino board. I had to use tools like oscilloscope to make sure that signal we are getting out is realistic and not just noise.

    What I learnt:

    1. I have learned a lot about working in a group and in a “real work environment”. I have seen how are the roles shared based on persons’ talents. Pressure makes results and in this short time we needed some pressure to finish the project. Unfortunately this time time ran out and we just didn’t have enough know-how.
    2. Making a better presentation.
    3. Communicate with English better.

    • Mikko Heikkuri

    I connected all the hardware components of the nexus system, like NX2 server, WSI box, GPS, wind transducer, speed sensor. I built a level shifter which it was responsible for switching/alternating the voltage level so the arduino controller can connect with nexus system. Also i helped with programming the arduino micro controller.

    What I learnt:

    1. Teamwork first of all
    2. More hardware components
    3. Programming and using arduino alot
    4. Learned about oscilloscope
    5. about NMEA protocol and sensors
    6. Learned to make better presentation

    • Stefanos Athanasiadis

    I was responsible for updating the wiki page and documenting the project progress. I also help testing the functionality of arduino micro controller, did some run testings. Another thing I did was making the presentation, and some various small tasks.

    What I learnt:

    1. I learnt how to program C language in Arduino.
    2. Researched in Google Android API v.2.
    3. Communicating and working with other people is essential when working in a group.
    4. How to plan your work in a short and pushy timetable.
    5. How to make better presentations.

    • Kristjan Tõnismäe

    My task here was updating the wiki page and documentation the project. Also helped with some tasks, helped to make much better UI design. I helped to understand java and Android parts. I tried to give as much ideas to the project as I could. I did research for java libraries, what we used.

    What I learnt:

    1. How to do work in a big team with serious project.
    2. I learnt a lot of English language, practiced it a lot.
    3. I understood more about marine censors and Nexus equipment.

    • Jesse Koski

    I was responsible for graphical user interface to Nexus android design and drawing. I did research for java (UI part) and arduino code. Also i helped with the arduino code.

    What I learnt:

    1. working in a project with different people.
    2. How hard is to get different devices work with each other.
    3. How much time it will take to get enough correct information.

    Final documentation


    The client wanted a fully functional system, or a toolset for race sailing performance analysis. With this Instrument trainers and analysts want to calculate new courses and provide assistance to the Estonian Olympic race sailing team. Also the client desired a marine sensor measurement visualization, and a minimalistic GUI design with a map, that means that they can use a simple portable device to overview the course. Also they required some physical buttons that they will let the trainers to collect and show the necessary information. During the collection of the data, difficult conditions such as bad weather and full wind speed, will not allow the trainers to use a touchscreen tablet device, that is why the client desired the physical buttons.


    We are creating a system for sailing purposes that consist three parts. Nexus Marine sensors, Arduino micro-controller, android tablet application. The marine sensors are especially made for sailing purpose to gather information about boatspeed, gps coordinates, wind direction and wind speed. After collecting the information, we are forwarding them to arduino and from there to an android tablet with an android application. The marine sensors are wireless connected, the connection between the nexus and arduino is done by serial port RS-232 and the final connection from the arduino (android shield) to the tablet is made via usb cable. We have Big Physical buttons to control data since our client doesn't want to interact with the tablets touchscreen, this tool will be used on-boat thats why the physical buttons are needed, also the tablet will be in a special waterproof case, so it will be protected from the harsh conditions. The Graphical User interface will be simple, using Google-android API v.2 the background will be a map, the controls will be easy also, and simple to improvise for the use of trainers and analysts.

    IP Feed-back

    Kristjan feedback

    Everything was very well organized.

    Stefanos feedback

    During this IP seminar I learnt the importance of working in groups with other foreign students. Communication is essential for understanding what the client needs and wants, and how to work together. The lectures were impressive and interesting. Lectures that had to do with security testing, network protocol analysis, data mining were irrelevant with the IPs subject. The whole IP experience was amazing, and the IP coordinators were professional with their work. It was well organized, a perfect timetable and responsibilities. Keep up the good work! And good luck with your next Intensive Program, because you deserve to have another.

    Mikko feedback

    Everything was well organized so thanks. Special thanks to my team and everyone i met.

    Tommi feedback

    Everything was organized well, food, events, everything. Even though the course was pretty intensive, had we a great time with my new friends. I wish that our mentor would have been more with our team and could have been helping us more with our problems. Thanks for this experience

    Jesse feedback

    it was great to be involved in a project and working with completely strangers. I got a lot of valuable experience from working in a project and what to do when a problem occurs. In our project i would liked more guidance, because there was so many different things to learn and those different things what should have been learned were too wide for this program schedule to completing project.

    Konstantinos feedback

    I liked: The planning of the IP was excellent. The lectures and the activities were beyond my expectations. I met students and made friends with people from different countries. I drunk "a lot" of beer. The project was very challenging, interesting and motivating. I gained new skills like, arduino programming, ADK programming, NMEA parsing, team building, task managment, time managment(failed miserably on that one) and socializing. :D

    I didn't like: We didn't finish our project. We have to leave.
