Build marathon day 2: With a bit of convincing our arduino indeed agreed to co-operate. Calibrating our compass and accelometer required some dancing with the hull (see video below) but they are now calibrated. The weather is wonderful and luckily today we are testing and calibrating stuff so we get to go outside.

Väinö is enjoying Finnish summer with our submarine. Arduino was a bit grumpy in the beginning.

Good news again! We got our propeller spinning (see the video at the end of this post). Now we only need to fix our problems with the GPS and Compass and we are very close to the first swim of this beauty!

It’s been a long struggle to get the submarine water proof but after couple weeks of trying we finally got the hull water proof!

 
No leaking even though we filled the almost the whole hull with water! Hope it works from outside to inside too. We also tested the shaft seals and they weren’t leaking either.

We also connected the rudder to the servo motor and it’s working great!
