Build Your Own Submarine

Nerobro writes "There's a group of geeks out there who are bound and determined to build their own submarines. In fact, there's a large group who have been successful. The most interesting is Cartsen Standfuss's CSSX-1. There is a mailing list, owners group and sizeable archive of information at psubs.org."

Hobbyist submarine accident

[infolib]

Peter Madsen successfully operated his homegrown 1-man submarine in the harbour of Copenhagen last fall. It has been submerged for 1½ hour, and gone to a depth of 10 m.

That came on the heels of an accident where his submarine was heavily damaged by crashing into a bridge. Don't blame Peter though - it was carried on a truck! (danish)

During the test this fall the only problem was paranoid police boarding the sub (danish) to assure that Peter was not an activist intending to disrupt the EU summit.
