Marching to Occupy Wall Street

October 5, 2011, NEW YORK NY. Steve Bull was discovered at 6pm EDT in a march supporting the Occupy Wall Street protest.

DOLPHIN by Hereshoff

Tomorrow I am going to crew on DOLPHIN and the last time was in the 1960s. I also varnished the bright work and performed other maintenance duties with my brother Jeff. John Lockwood was skipper then. Dolphin is a Herreshoff designed Newport 29 that is currently cared by Oakcliff Sailing Center.

Croquet with lawn chairs

My brother Jeff got married to Marilyn last week [09/10/11 12:13] in Westport. As an after event treat I positioned the reception plastic furniture for a game of croquet. The newly wed couple won over the other 3 brothers and their spouse partners: Steve & Terese, Jay & Cindy, Ware & Kahsia.

Castle Brunnenburg

In March 2011, I visited long time friend and author Mary de Rachewiltz at her family Castle Brunnenburg. I first met Mary years before when I was European location scout on the PBS Voices and Visions documentary of Ezra Pound.

Three of the Herd

This will be the first year and my first time ever owning cattle. My herd will be very small, 8 to 15 animals. Individuals are bought in small numbers from nearby raisers or purchased at the end of the auctions after the bigger sized lots are sold and almost everyone else has left that event. Scott is raising them for me and the cattle are grazing on the organic buffer strip planted around my organic crops. The buffer strip is a barrier to prevent contamination by GMO crops that is the predominant new normal agriculture in western Nebraska. I favor heritage seeds and sustainable agriculture. The herd is not organic and I am participating for just a short time in the economic life cycle of this protein source.
Caveat: My = Terese Sovoboda and I (wife and husband, farming partners).

Aerial Fish Fertilizer

I spoke to my organic farming partner in Grant, Nebraska last night and he said that our crop of corn looked pretty good, a little more rain would help finish the growth. He has been busy this summer that included taking the opportunity to plant millet into tilled soil that had peas and oats growing earlier in the spring which were planted into last year's sunflower stalks. In this late summer break before harvest time he will bill me for my share of the fertilizer he had applied to the corn by airplane. The fertilizer included some fish but also a number of other components, such as seaweed and micro nutrients. The photo is imagined.

50 oysters in a pail

50 oysters in a pail with the gear required to service these mollusks. Crocs for wading. Scrub brush for cleaning the oyster cages of squirts that block the flow of tides, and the brush makes the oysters themselves look their best. Heavy duty rubber cloves protect the hands from the razor front edges of the shells.

1500 oysters in cages that will soon return to hanging from the dock of the Harbor Knoll Bed and Breakfast in Greenport NY.

Use Gin to Clean Knot Hole

Back Story: The plug fell out of the knot hole in the floor of my old house. Coincidentally, I was building a spar for the lug sail of AEOLUS and I had left over thickened epoxy. I put the epoxy around the inside of the hole and the outside of the plug and gently hammered the plug back into the hole. See above photo.

Helpful tip: Epoxy had dribbled over the edges and I had run out denatured alcohol that I usually use to cleanup the mess. I remembered I had a new bottle of New Amsterdam Gin. I poured the gin on my clean up rag and cleaned the area around the hole and the plug.

I found Neptune's bicycle between the ebb and flood on the beach next to LIRR station in Greenport NY.

Selling Cornflakes

This photo of me comes from the shoe box photo archives of colleague Brian Perkinson. I confess that as crew in the movie/TV industry, as well as member of the DGA, to aiding in the legal sale of corn flakes, kitchen detergents and after shave tonics that are "necessary" products in today's consumerism. I was "sitting-in" for the DP and gaffers in a lighting check. The folds in the photo delineate the frame of the shot masking out the back light and rest of set. The grip stand in front me of was a temporary spatial marker. While the further details of this particular job elude me, a close examination of the digital watch on my wrist should give a clue to the decade of this early Polaroid image.

Oyster Report - June 10, 2011

I spent several hours at the Cedar Beach Creek facility of SPAT: Cornell Cooperative Extension of Suffolk County working on my 1,000 oyster crop that over wintered there. I brought a few back for taste testing.
My progress report:
Fall 2010 tasting = 24
Early Summer 2011 tasting = 49
5 cages x 100 = 500
7 cages x 50 = 350
Hollow shells = 31
Total accounted = 954

Kim Tetrault who runs this Southold cooperative can also be discovered locally playing electric and acoustic bass with Jazz on the Half Shell.

Andy Goldsworthy's Rivers and Tides (video)

This was my first exposure to Andy Goldsworthy's artistic practice. His connection with rock and others fundamental elements then launched into the forces hidden nature inspire me. Huge praise to Thomas Riedelsheimer, director+cinematographer+editor, who elegantly captured the ephemeral in Goldsworthy's work. This movie was made in part with funds provided by Scottish art lotteries--bravo--I'll buy a ticket next time I'm there. Rivers and Tides is available as a DVD order from Amazon. I saw it as immediate play on Netflix.

Nautical object

What is the name of this nautical object? Where does it get positioned on the boat hull? Orientation star upwards? Terese got this for me last year when she teaching for the SLS in Lamu, Kenya. I want to attach correctly to Aeolus.

Against the wind

Despite the drizzle and gale winds last Saturday, the opening of the Décollage: Torn Exteriors Show in Williamsburg was nicely attended. Above is an iPad2 screen grab of my work "After Delvaux" and here's a video made by Stephen Heiden.

Orca scene [pun] in waters off Greenport

I just finished an orca scene plunging into the waters off Mitchell Park in the Village of Greenport. This concept image is an .png 2D export from Google SketchUp and is to be included as an AR component of "Cellphonia: Whales" in my NYSCA proposal. And yes, I know the orca is not native to Greenport waters, read Wikipedia to learn more about he orca's usual habitat. The orca source is courtesy of Mandun.

Bogliasco Fellows - February / March 2011

These are the edit selects from an augmented reality installation study recently made at the Villa dei Pini, Bogliasco Fondation, Italy. I was there as a guest of the Fellow Terese Svoboda.

Flavio Ermini in garden of Villa Dei Pini

Flavio Ermini is Bogliasco Fellow in Literature - Creative writing in the 1st semester of Fondazione Bogliasco progam in 2011. I am in the process now of placing him and the other 6 fellows into the garden of Villa Dei Pini adjacent the main building. This is part of a work in progress toward a larger AR installation project. I am working with Google SketchUp and you can download this image object from their 3D warehouse titled as Flavio Ermini in garden of Villa Dei Pini.

Villa Dei Pini (work in progress)

at 44.379856, 9.059553

I just posted model "Villa Dei Pini (work in progress)" to my warehouse and this is a geo located villa that still needs a roof and photos of the exterior walls painted onto the basic shape.

However, at this stage when I position the building into the terrain, the terrain is not adjusted for the grading to the grounds adjacent the the model walls. Thus the uphill portion of the model is buried while the downhill side of the model is suspended in the air. What is the procedure to correctly place the model? Do I need to also create the terraces in the terrain around the building?

I am a guest here for 10 more days and I would like to get as much finished on this project as possible so any immediate comments will be much appreciated.

Fishing Boat Haul Out in Bogliasco

The method of embedding wooden beams across the boat ramp is smart. The hull is hauled over the forgiving wooden beams rather than roughly abraded on a beach, rock or cement shingle. The principle advantage of not putting the trailer in the salt water is the wheel bearing do not get wet and the trailer suffers less rust. A public electric cable winch pull as the men guide the hull.

I took a beginning Tarot seminar from my longtime friend Donna Henes and this was the first card I pulled in a self directed one card reading. Tarot provides an interesting contrast to the stricter demands of my usual citizen scientific investigation, engineering and coding practice. As a follow up Tarot exercise I vow for one month to pull a card a day and read the flow.

Arctic National Wildlife Refuge

"Every year, people in all 50 states and across six continents see birds in their own backyards that begin their lives on the coastal plain of the Arctic Refuge. The Arctic National Wildlife Refuge is home to more than 200 wildlife species including polar bears, musk ox and caribou. Wildlife and mankind are already under stress from the impacts of climate change. Put this cause on your agenda and focus your energy to designate this area a National Monument and you will protect a critical habitat for wildlife and help preserve biodiversity."

Everyday my email in-box has petitions from worthy causes that I have supported in the past. I endeavor to respond to one of them each day and delete the rest. The copy above was added to an automated letter to be sent from me to President Barack Obama. This service was expedited by the Sierra Club. The link to the USA federal government Arctic National Wildlife Refuge site is http://arctic.fws.gov/. Here is Wikipedia's entry at http://en.wikipedia.org/wiki/Arctic_National_Wildlife_Refuge. This is authentic living 11/11/2010 and I personally support this message. Meet me to verify.

AEOLUS is nesting with other dinghies at Children's Beach in Nantucket. She was there this last weekend to transport the Lochridge family members around the harbor at their 4th annual reunion on the island. In the background is the ferry EAGLE of the Steamship Authority that transported Aeolus to this destination.

LEO Space Farm

From the archives I discover a paper "Low Earth Orbit Space Farm" (1986) written with Nils Bruun and Randolph Liebelt and presented at AIAA conference in USA and IAF conference in UK.

ABSTRACT
The paper proposes a modular low earth orbit space farm which combines the current CELSS technology with a single launch, artificial gravity space vehicle to provide fresh produce to a nearby space station crew in a balanced exchange for their biodegradable waste and carbon dioxide. While growing a substantial amount of produce, the space farm will also be developing the plant propagation technology for transfer to future lunar colonies and to accompany long range space missions, ie. interplanetary exploration. The components of the space farm will be launched by conventional booster, then manned, assembled and operated by a crew of two. Since the space farm is habitable during all stages of development, the shuttle rendezvous will be brief. Adding modules will facilitate increasing crop yields.

Transfer resistor = Transistor

My son Frank sent me a link to HOW DO THEY REALLY WORK? by William Beaty, BSEE 1995 and I am pleased to report that this is the best explanation I have ever read on transistor basic principles. For years and years I was baffled by all previous explanations and this article told me why. There are useful links at the end for more visualizations plus a nifty article on Iron Pyrites Negative Resistance Oscillator with a DIY cat whisker radio.

Global warming: Who are the leaders?

My question that I posted to Avaaz.org site for them to pass onto Gordon Brown.

"Curbing global warming requires change of life style for western nations. My fellow citizens and I are ready. But where is the political leadership with the voice and the will to present this future. This future is a bright future with bicycles and public transportation and spending more time strolling with family and friends. Children will be taught to weed and cultivate victory gardens. Who are the leaders that will set an example and steer the new course?"

Avaaz reply: Thanks for RSVPing to today's phone conference with UK Prime Minister Gordon Brown. This meeting with him is a great opportunity for us to engage with power as citizens around the world. And we'll keep him on his toes!
