January 29, 2007: $300 Homemade spy sub
It's Neatorama collaboration Monday!
Dugg today is this homemade spy sub, which is documented on Popular Science.
| Some fathers and sons play catch. Electrical engineer Jason Rollette and his 12-year-old son Trevor are a little more ambitious. Hoping to explore the lakes and rivers near their Milwaukee home, they’ve built their own underwater remote-operated vehicle, or ROV. Controlled and powered by a laptop, their ROV can swim more than a quarter of a mile, to depths of 250 feet, while a home-surveillance camera sealed inside sends a live feed to the pilots onshore. |
It has little lights on the front, so it can illuminate what the camera is looking at. It's controlled with a joystick and computer interface. The down side: a quarter-mile-long Ethernet cable. I guess wi-fi doesn't work underwater?
Be sure to visit Neatorama for more neato items every day.

| The technical details for making such a call have been in place for years. The three-person crew aboard the Alvin--submerged 2.5 kilometers below the East Pacific--communicates to the surface ship Atlantis via acoustic transponders, a type of underwater telephone. The phone on Atlantis is in turn connected to a satellite phone, which can buzz anyone on shore. To complete the sea-to-space link, scientists merely needed to have Atlantis call the NASA Johnson Space Center in Houston, where a high-powered dish transmitter speaks directly with the space station. |

Of course I'm not trying to send any info along with the power...
