A sailors molecule

H2O: Dangerous Chemical!

A student at Eagle Rock Junior High won first prize at the Greater Idaho Falls Science Fair, April 26. He was attempting to show how conditioned we have become to alarmists practicing junk science and spreading fear of everything in our environment. In his project he urged people to sign a petition demanding strict control or total elimination of the chemical "dihydrogen monoxide."
And for plenty of good reasons, since:
  1. it can cause excessive sweating and vomiting
  2. it is a major component in acid rain
  3. it can cause severe burns in its gaseous state
  4. accidental inhalation can kill you
  5. it contributes to erosion
  6. it decreases effectiveness of automobile brakes
  7. it has been found in tumors of terminal cancer patients
He asked 50 people if they supported a ban of the chemical.

  • Forty-three (43) said yes,
  • six (6) were undecided,
  • and only one (1) knew that the chemical was water.

USB Config & Pi Zero

I spent some time this morning putting together this picture that defines  the USB configurations and pinouts for various USB types.  The reason for this is that I want to make a Pi Zero CCTV using the popular motionEye software.  I have made several using the Raspberry Pi 3 but am finding it too expensive for what application I am applying.  Now, if I were using 2,3 or 4 CCTV then It would be a good deal to use the Pi 3.  However, for a single CCTV it is too expensive.  To this end, I may need to add a USB hub to the Pi Zero so I bought some tiny hubs on a single PCB this morning.  It has 4 USB A Standard size with 1 microUSB B.  All for $3.78 each and no shipping.

Future Weather

I have been meaning to post the link of a new breed of interactive weather maps that has lots of applications for pilots, sailors, farmers and everyday users.  So here it is in all it’s linked glory.  The only reason for me to do this is so i will not forget where to go to get it 🙂

2017 is here

The nautical experience has been nil since the last post.  Well, not exactly but it has been contacting those who are "doing". Listening too.  Right now I am listening to BBC interview by Kim Chakanetsa   with Jessica Watson and Rose Savage. Both are sailors and describe their experiences at sea when they were about 16 years old. It was so interesting I went to sleep momentarily. This is not to detract from the podcast but because I had a big lunch about 1/2 hr before.  Sorry ladies.

Energizer Bunny feeling

The last two days I have had a fit of energy and am making Monkey Fists and paracord bracelets and just tying knots in general.  There should be lots of gifts for the grandchildren that they may not appreciate until they are 40+ years old.  I have had this paracord just sitting in a box awaiting a new project.  Believe it or not but I like the camo paracord the best for most projects and then comes white and then black.

As I sit here awaiting Christmas, I am watching the snow build outside.  The snow has been coming down for about two days now - sometimes light and other times moderate - and has accumulated 4". The barometer is about 29.98" and was falling rapidly and we have a SE wind about 7 Kt.  I do not want to go out and make tracks in the snow that will be hard to plow later.  So we sit here in our cocoon but I really wish we were on the water in FL.

Leaving a legacy of knowledge

We have two sailing blogs, one, this one was purposed to be a day to day journal on the water. Somehow when we sold our Youngsun 35, Inspiration, to Bob I envisioned a very quick transition to another boat in more southerly waters.  Life intervened and now it has been since end of season 2011 and no boat.

To be sure we did own Inspiration II for a few seasons but she never really felt like mine and roaming the deck of a Irwin 43 felt foreign to me.  This is something you do not know until you have been acquainted for a while. While below it felt like a nice small flat.  It was reasonably nice to roam around and enjoy all the comforts of home.

The problem came when I envisioned myself as skipper - I did not know or feel real comfortable with all the systems.  Sure, I could repair most of them and the electronics was a slam dunk but there was so much to go wrong that we relied upon for a safe passage.  For example, we had 440 AH in two banks of 220 each. Considering that we would use about 20 AH while running the refridg, autopilot and the rest of the electronics, this gave us one day of power while under way.  So, if the generator did not start recharge us every day for about 3-4 hours the boat was powerless after 2 days.

The main propulsion was rock solid and if we ran the engine we could stay on top of the energy supply and I suppose we sail only 50% of the time.  The generator was 8 KW so it would power the battery charger, Both AC units and all of the electronics, including running the microwave without the main engine running. We had a separate, dedicated start battery for the generator.  The main engine started from the house batteries. ( I am publishing and will continue  in Episode 2).

No Deal

We asked for our Cowabunga deposit back and have been told the check is in the mail.  Not too much else to say except we were a bit surprised that a counter offer was not made.  Even one of a nominal price decrease.  Perhaps, we were not communicating with the broker very well but I do know that a few of the brokers I have worked with would not have given up quite as easily,  There may be mitigating circumstances of which we are unaware so we hold no malice towards anyone in this deal (or no deal as in this case).  It was kind of a long trip for so little return but we did get to have my friend Don's old bridge open for us and that was a first ( Don was the bridge tender until his retirement and we visited him on the job).
