Madox is building something he calls the MFC or Madox Floating Camera.

Presently, it consists of an Asus WL-520gU wireless router mounted in a waterproof box along with batteries, a relay control board, and four large bilge pumps for propulsion.  He plans to add a camera so he can take his contraption to the Australian Battle Group meet in June where he “hopes to film the ships shooting each another to smithereens”.

His latest post includes a video (above) of the propulsion system being tested in his bathtub.  I can’t wait to see some larger scale tests, it looks like this rig is capable of some serious speed!
