- calebhawk, on 10/12/2007, -0/+12great... i can't wait to "spy" on fish and scuba divers...
- Fire4Effect, on 10/12/2007, -0/+11What the article doesn't say is that on the weekends daddy takes it to the nude beaches.
- calebhawk, on 10/12/2007, -8/+18... and a ho made this?
- alternateheaven, on 10/12/2007, -0/+7If he was using the cable to carry internet traffic, however as show on his website its merely being used because its easy to get huge spools of the stuff and its got 8 different wires that can be used for whatever the project may need. Besides, going tcp/ip would be a little overkill for a submarine and with the size of wifi transmitters it would probably be easier to go that route.
- actorboy, on 10/12/2007, -0/+6I worship you.
- strikerInsane, on 10/12/2007, -2/+8OK Does anyone else think that the host of this blog is somewhat of a nutcase? Read his profile. "When the last Jew dies, so do we all!"???
- isewise, on 10/12/2007, -2/+8The name of his blog is "The WTF Blog"
- luketabor, on 10/12/2007, -1/+6A bit of intelligence on the part of the submitter would have been very welcome. I mean, come on. It's not THAT hard to spell "homemade." They even do it for you in the article you submitted.
- sacherjj, on 10/12/2007, -0/+5We built one of these about 10 years back, although a little simpler design as far as propulsion. As to how you would retrieve it, read the article. It is controlled and powered by an ethernet cable umbilical. I would assume that they did something similar to our setup. You can use polypropylene rope (ski rope) and run cables inside its hollow weave. It is very difficult to have any type of radio signal transmit through water, and therefore it would be difficult to control it with a wireless connection and impossible to get enough bandwidth for usable video. We wound up using onboard power, as we needed the ballast weight anyway, but sent control and received video via an umbilical. It is much easier to base depth on a floating surface craft with a winch and set the submersible to just be slightly negative buoyant and tow along the upper winch craft.
- Ulvund, on 10/12/2007, -0/+4Yeah, Einstein failed math so dumb is smart.
I rule at logic. - 800266622, on 10/12/2007, -0/+4don't worry, be happy
maybe the submitter ran out of characters and deleted one in order to spell AWESOME right. Maybe the submitter had a typo. I know its hard to believe in this age of spellchecker, but occasionally some of us press a little lightly and the letter doesnt make it into the text. No reason to get all over his case and immediately label him as dumb. - eatmyjustice, on 10/12/2007, -0/+4I’ve started to bury anything that has the word AWESOME in the title.
- inactive, on 10/12/2007, -0/+4"and with the size of wifi transmitters it would probably be easier to go that route."
Are you suggesting trying to use wi-fi underwater? Given the attenuation from the water the signal would probably go about ten feet. - inactive, on 10/12/2007, -0/+4328ft is the length for using ethernet cable for tcp/ip, not for using it as a length of wire to only send control signals and power... It's just a convinient way to get a long sealed wire in a very long length.
- repairman, on 10/12/2007, -0/+3Did anyone else check out the torpedo button on that GUI screen shot? Thrusted waterproof firecrackers would be an awesome nice-to-have.
- ZynX, on 10/12/2007, -0/+3Here's the creators website detailing the step-by-step process (visually):

He is a real creator working on lots of projects. His homepage lists them. - LGgeek, on 10/12/2007, -0/+2agree that the reference should be to the creators website, as far as everything else the reason America is falling behind technologically isn't education it's lack of imagination or institutionalizing borg think.
We should applaud anyone that shows the initiative to think beyond the latest YouTube video or MySpace entry. Who cares that it has wires,etc at least their brains shows signs of being alive. - alternateheaven, on 10/12/2007, -0/+2Definitely awesome for the fact that it was all home brew and not a kit, however it still cant touch http://www.rc-submarines.com/id47.htm in terms of coolness especially since they can do not only torpedoes but SLBM-style missiles as well :D
- inactive, on 10/12/2007, -0/+2how can they transmit enough electricity to the sub for the pumps, the camera and all the mechanics through an ethernet cable? especially the pumps... pretty awesome...
next upgrade: wings and propellers to make it fly out of the water. - zoltan, on 10/12/2007, -0/+1convert to AC? i could see a nice powerful signal being used. maybe some lithium polymer batteries? too bad all that stuff isnt chump change
- sacherjj, on 10/12/2007, -0/+1I am wondering the same thing. The sub we built about 10 years ago had onboard 12V, and we just sent control signals encoded down a single wire plus ground. I really don't see enough power going down 22 gauge wire. Perhaps they ran both Ethernet and a fairly decent sized zip cord for power (18 gauge?). If they wrapped a decent shell on it, like a polypropylene ski rope, you wouldn't care how many wires were in the umbilical. We had small diameter coax for our video, because of losses due to control noise when running in standard twisted pair.
- PacoDG, on 10/12/2007, -1/+2Heh, yes "Homade"
I was fooled, I thought this was a real sub, not remote controlled (does this still count as a "Submarine" by definition, since its controlled from outside the water?) - sacherjj, on 10/12/2007, -0/+1Oh, to cover your next upgrade... Look into water displacement and weight involved to be neutrally buoyant and you will find that making a submarine that can fly in air as well is pretty hard. Then only way I can see it happening is if 95% of the submerged volume is water ballast that can be emptied to convert into flight mode.
- luketabor, on 10/12/2007, -1/+2OK, I'll give you that I shouldn't have called him unintelligent. After all, Einstein failed math class. But he definitely needs to learn how to spell.
- rouslan, on 10/12/2007, -0/+1This is NOTHING compared to this:

This guy actually made a REAL submarine from junk during the Soviet-era (when materials were scarce). And it actually works-he even travelled from St. Petersburg to Finland without stopping. And he doesn't even have a website. - OutcastJiob, on 10/12/2007, -0/+1Yeah, like some fishy lasers!
- elioty, on 10/12/2007, -1/+2Yeah, total nutcase. Here's his profile:

- inactive, on 10/12/2007, -0/+1Technically it's an ROV but it's still pretty cool.I think I might build one myself I have half the parts on hand.
- darknightapple, on 10/12/2007, -0/+1The Pirate Bay could submerge a submarine like this attached to a small linux webserver. Try shutting down the Pirate Bay now ya blimey barnacles, arrrrgggg.
- 30ODD6, on 10/12/2007, -1/+1Thats friggin Awesome!! Next time on on vacation staying at a resort im gonna use that baby to torpedo peoples rafts!
- zoltan, on 10/12/2007, -1/+1I live in Milwaukee and have got an even better submarine if you foos want to ever check it out. This puppy runs on swiss precision submersible diesel engines. I say we have a showdown
- Dujenwook, on 10/12/2007, -0/+0Fairly ballstacular, imo.
- brentis, on 10/12/2007, -1/+1eh... I think this is diggable if it was wirelessly controlled vs. having a 1/4 mile tether.. Hard problem to solve, but anyone who has ever gone fishing knows this thing is going to be snagged on something and unretrievable in no time.
- inactive, on 10/12/2007, -0/+0RF doesn't propagate well though water you will loose signal after it goes down about 30 feet.
- bullox, on 10/12/2007, -5/+3The problem that some people might not see is the fact that he is using a quarter-mile long ethernet cable to transfer data, video, etc. Ethernet works up to 328 ft, or much less than a 10th of a while. I wonder about the validity of the report and/or the claim of quarter mile range.
- JANREHAN, on 10/12/2007, -4/+0asdfasdfd
- GTanaka, on 10/12/2007, -5/+1Ummm...this isn't exceptional. There's competitions everywhere for building ROVs. Hell, I built 1 myself in my junior year of high school.
- inactive, on 10/12/2007, -6/+1Might as well tie 300 bucks to a rock and throw it into a lake. This article is an advertisement and not a true analysis. They don't mention how you would recover the unit if it had probs.
Can you say Mars Rover? - JimmyDushku, on 10/12/2007, -11/+5It's good to hear Mel Gibson is spending his time blogging.
