Help with the ROV Tether.

Daniel and Rob

Danial and Rob, two engineers on their way to race their car in Nebraska, stopped in and we tested a length of RG6 inside some tubular webbing.  Unfortunately the tubular webbing stretches about 35% with just 300 pounds of load and that was too much for the RG6.   So we need your help.   But please stay within the parameters. We are not a government agency and we do not want to act like one.

We are looking for:  Cheaper, Stronger, Easier, and More Widely Available for 60 cents a foot.

So what is the best combination of polypropylene tubular webbing, coaxial cable and strength member, either steel of synthetic so that we have a low cost, neutrally buoyant, anti-strumming, tether that can sustain a 1000+ pounds of load when towing?

How much will coaxial cable routinely stretch?

What is the working load for common RG6 with a messenger wire?

Two weekends ago Betsy and I were in Florida checking out a Junk Rig.  Last weekend, Bart, Jack and I were at the Tulsa Mini Maker Fair showing off Seeker, the ROV and recruiting help.   And this weekend is our open house.  So when do we have time to build something?   We are building something.   We are building a community, and it is that community that is making Seeker possible.

Drew has the new guidance IMU component for the ROV and working on new code for it.

Patrick has gone through OpenROV’s code and started adapting if for  Seeker’s ROV.

We met Barry from Navico at the Maker Fair, and he happens to be the mechanical engineer that worked on the Lowrance side scan transducer.   He answered some important questions and will be a great resource moving forward.

We also met Zachary who had a great idea for using Coax instead of Cat5 for the ROV Tether because it’s smaller, cheaper, and there is a gadget that can run 10Mbps Ethernet 1.5 miles over RG6 coax.  See more here.

And that the way it goes.  Invention and construction are best done as a community.  Nothing worth doing is going to be easy.  It’s going to fail many times, it’s going to take longer that expected, it’s not going to look like what you envisioned in your head,  it’s going need to be attempted again and again.   Community is not just about finding the best answers, it is there for support.   So come out to our open house this Saturday 10 to 2.   See what we are doing and consider joining our crew.

Ondine

In the quest to better understand the Chinese Junk sail, Betsy and I found ourselves it the company of Pat and Jeannine, on board their schooner Ondine.   We enjoyed a wealth of knowledge and a beautiful sail through Ponce Inlet from New Smyrna Beach, Florida.  We highly recommend the short voyage.

Sailing on the “Schooner Ondine”, New Smyrna Beach, Florida

DougRigging, Sails, Steel Boat

Had a most Excellent day, sailing with Pat, Jeanine, and Lee on the junk rigged Schooner Ondine, which does day sails our of New Smyrna Beach, Florida.   Pat and Jeanine have been doing this for four years and also work on the tall mast ships and do sailboat deliveries.  It was a pleasure to tap into Pat’s extensive experience with this rig.   When Betsy and I walked up to the boat we were both taken back by the myriad of lines running down the mast and heading off in all direction, but four hours and a hundred questions later we both think it’s a piece of cake.   And I am seriously underwhelmed by the structures required to rig this boat which has done it’s share of blue water voyaging.  Comparatively Seeker is a beast.

Some ideas take root and grow faster than the weeds.  SV Seeker is one of those ideas that started from a chance conversation about building a boat and getting it to the ocean via the Arkansas river.  That was about 12 years ago and the though of sailing a boat I built across the oceans was something that scared me.   …and it made me feel alive.   And it still does.  What’s the point of living if you don’t LIVE.  Feel the fear and do it anyway.

If you are in or near Tulsa, we invite you to come see us at the Tulsa Mini Maker Faire,  or stop by for a visit on Saturday, September 3rd from 10am to 2pm.   –Doug

Low Cost ROV Tether and more…

Do-It-Yourself ROV tether for 21 cents a foot, (69 cents/meter) and 300 pounds (1300 Newtons) of load.  SCORE!   And we are looking forward to your suggestions for improvements.   Thank you for your assistance!

 

 

 

 

 

 

 

The New Plan

DougSteel Boat

The old plan was to have to ROV in the water this weekend and on display at the Tulsa Maker Fair in two weeks.   ….I hate that plan.  Deadlines suck the enjoyment out of most everything.  I understand the need for them especially when other people are counting on you, but that is not the case.  This was self imposed.  It did not make me work any harder or better, it just made normal work feel like pressure and failure where there was no failure.  I though I had learned that lesson.  Over a year ago I took down the “Count Down to Launch Clock”  from the web site.   That felt great.   And we have worked more and completed more on the boat this year than any previous year, and did it joyfully and while taking time to learn new skills help others learn new skills.  We are about enjoying life and enjoying the journey.   No more deadlines.   We  LIVE now and sail when we are ready and the wind is blowing.   We enjoy every moment.   If you don’t then you miss the special things.   Like those socks.   Much love and appreciation to  our supporters and especially the Seeker Crew.   Betsy and I are off to Florida next weekend to see this thing they call an ocean and scout out a Chinese junk rigged sailboat.   Jack and Bart are in charge of the boat yard.

ROV Sonar Part 5 and Hull Tool

DougROV, Steel Boat

vs160801-001   The ROV the internet built!  We got a lot of great ideas for out ROV Hull Tool.   You can see them on our last post: ROV Hull Joint Tool but the one recommendation you don’t want to miss was from Eddie DaGrouch.   We are not accustomed to things working on the first try.  We often use the motto “We build it right, because we build it twice.”  …but Bart Robinson cobbled together a tool that works like a charm.

We also had some success in getting two sonar transducers to share a Lowrance SonarHub.  When successful, we will have a deep water ROV with both forward and side-scan sonar abilities a fraction of the cost of commercially available products.    –Doug
