PRE-TEST IN SINK

Before taking the device into the ocean, i made sure it was floating. if it was balanced and if it was actually completely waterproof.

I tried many different containers to see what different shapes would act like.

I also think i should use the Arduino mini and summarize everything onto one single board...

and i think (especially after the following experience) that i should maybe use a remote controlled boat to drive the device into deep sea and back.
