I don’t know of many people who watch sailboat races, but I am one who will. The Superfoiler series from Down Under is similar to the 18 foot skiff racing. This is a professional sailing series with the boats funded by sponsorship and big name sailors hired as crew. The boats are light, sail on [...]

Capn Andy/chilly winter easing its grip
The superfoiler race series from Geelong, Australia happened on their Sunday afternoon, our Saturday evening on the USA East Coast. I managed to fall asleep while napping so I could follow the action from about 10 PM to midnight Saturday. I woke Sunday morning.
.
I was able to watch the replay on You Tube and enjoyed the racing. I think the video clip is more than 2 hours long, but you can hit the right arrow key and jump ahead a few seconds at a time and skip over some of the interviews, etc., that are inserted between the races to fill time. The races were concluding about as fast as a Ted Talk, around 20 minutes. This is a new boat design and the crews are learning how to sail the frisky beasts. This is the second venue in the race series and the sailing was better than last week. I think this will be a weekly series for a total of five weekends.
.
In response to a question about fettuccine I was reminded of a dish called paglia e fieno, Italian for “straw and hay”, a dish with spinach fettuccine and egg fettuccine in an alfredo sauce and spiced with garlic and parsley, and including mushrooms and pancetta, or sausage, or diced ham, peas, and sometimes made with a ricotta and parmesan cheese to make the sauce. As I talked about it, I began to wish I had some. I was going shopping, why not get the ingredients and whip up a batch.
.
I have been using Walmart’s Great Value Garden Rotini as my pasta, when I can get it, because it has lots of nutrients in it, looks great, colorful, and the rotini has lots of ridges to trap sauce, tasty. Paglia e fieno is made from thin fettuccine noodles that ball up with the alfredo sauce. The pasta and the egg noodles are very different, but I made other compromises. I found a jar of Prego roasted garlic alfredo sauce and thus did not have to make the sauce from scratch, but it would have been better, just as using fettuccine would have been better.
.
A package of mild Italian sausage and a package of frozen peas were added to the shopping cart. I actually did try to buy the ingredients to make the sauce from scratch but some how missed the heavy cream on the shopping list. A box of sliced mushrooms.
.
There are many videos and online recipes of this dish and variations. One of the best is Susan Bradley’s Luna Cafe website which has a lot of other delicious recipes. She writes well and reminds me of Martha Stewart, in a nice way, because she takes tremendous effort to refine her dishes.
.
Because I exclusively cook on a stove top, never using an oven, a lot of restaurant style recipes are off limits to me. Many of Martha Stewart’s culinary works of art are born in the oven, so I can maybe adapt some of the recipes, but mostly they are out.
.
Most of the videos show the pasta going into a pot of boiling water and the ingredients for the sauce going into a large skillet. These are stove top appliances applicable to my galley. I have two two burner cook tops, one is alcohol and costs a lot of money, the other is propane and costs very little money, from Harbor Freight. This time I cooked in the communal kitchen on a single burner electric cook top.
.
First I cooked the pasta, drained it and set it aside. I used a 12 oz box of garden rotini.
Then I began the sauce. Most of the chefs are doing the mushrooms and peas first in some order, then doing pancetta or sausage separately. I prefer to cook the meat first, then use the pan and the browned bits to flavor the other ingredients. The mushrooms are cooked a bit to release their liquid and the peas are lightly sauteed.
.
Traditionally heavy cream and parmigiano reggiano cheese is blended together in a skillet and melted and thickened to make the base for the sauce. Ricotta can be used together with parmigiano and sometimes a roux is started of milk, butter, and flour. If you forget the cream at the market, you may have grabbed a jar of alfredo sauce off the shelf. It’s not as good as fresh made from scratch sauce, but it is certainly very easy to dump the jar into the skillet.
.
When the peas and mushrooms are cooked a bit, the prosciutto or sausage or pancetta is added, then the sauce, mixture is allowed to mingle and coalesce. Next it is mixed with the pasta and served up. Some recipes add eggs or egg yolks to the cream, some spice with nutmeg or rosemary. It is similar to a carbonara sauce.
.
We tucked into the product and found that it was rich and filling. Think about cooking on a sailboat out there in the blue. You can try to balance things in the galley, but the more prepackaged items you use, the easier it is to cook, preventing unnecessary nautical language. Unfortunately most of the ingredients require refrigeration, but pasta sauce jars do not. Peas are a dilemma, you can use frozen or fresh, neither is preferred by the blue water galley cook. Freeze dried peas probably wouldn’t work out too well, as well as having this dish in freeze dried form. A carbonara would do better out at sea.
.
I steal photos from the internet all the time and I also offer a lot of photography on Flickr and don’t expect any compensation or attribution. The photos aren’t much good if I take them and view them and don’t get them out to anyone else. There has been some grief raised on the dpreview.com website about professional photographers being undermined by internet sites and users who steal images and use them and don’t do anything productive for the creator of the images.
.
I did not take photos while I was cooking in the communal kitchen. A fellow was doing his laundry at the other end of the room which is as small as a walk in closet. I should to a time lapse next time.
.
So, I am reduced to stealing another photo from the internet, of course from Susan Bradley’s excellent blog. It is the image she uses to illustrate Paglia e Fieno, but look how good it is, a sprig of rosemary at the back edge of the dish, slices of wild mushrooms, plus she includes the recipe she used.

I don’t know of many people who watch sailboat races, but I am one who will. The Superfoiler series from Down Under is similar to the 18 foot skiff racing. This is a professional sailing series with the boats funded by sponsorship and big name sailors hired as crew. The boats are light, sail on foils most of the time, and have a crew of 3. It looks like a weekly event and it’s viewable on You Tube. The footage consists of action cams mounted on the crews’ helmets and on other places on the boat, plus there is aerial footage.
.
My own little action cam, the i60e, was tested out recording time lapse video. I elected to use 760p as the format and left the camera running, sitting on the patio outside the woodshop. Ron the carpenter was using a thickness planer to prepare teak lumber for a big job renewing a large sailboats interior. I meanwhile got back to work on Kaimu’s starboard keel.
.
I started at the stern just in front of the rudder skeg and removed any fiberglass sheathing that wasn’t stuck to the wood and faired the gouges left from the impact with the jetty. After getting about 2/3‘s of the way to the bow I had had enough of the nasty fiberglass dust. I could use a respirator and keep it out of my lungs, wear ear protection and keep it out of my ears, but it would find a way down my neck, under my sleeves, and I had to stop.
.
Back at the woodshop I stopped the camera and played back the video. It was comical to see Ron jumping back and forth and the wood planks running through the planer at high speed. The video was shot a frame at 3 second intervals, so it was running about ten times faster than normal speed.

i60e Action Cam

With my main distraction, the quadcopter drone, out of the way with a burnt battery charger, I had no excuse to malinger. I had an unpleasant task that I was avoiding, sponging out the bilges that were somehow collecting rainwater. It is hard for me to contort myself down under the galley table, under the dinette, where the bilge’s lowest point is in the starboard hull. The fluids that make it down to there look offensive, so I used the same disposable gloves I use for painting to sponge out the water. I got about 3 gallons out, doesn’t sound like much, but each drop had to be squeezed out of the sponge and it took a while.
.
In the port hull there was an accumulation, not as bad, and soon both hulls were dry, more or less. It seems that water takes a while to drip drip drip back to the lowest point. I left the cabins open to help dry them out.
.
The micro SD card for the action camera came in, so I loaded it into the camera and formatted it. I shot stills and some video. One glaring (literally) problem was lens flare. Also high white levels are too high. Digital video is kind of like paint by numbers, you can’t go higher than 100 percent white, there is no number for it. As a result the software has to do something to compensate. TV cameras play around with the values of the bright areas of the image. They start to reduce or compress the values as they approach 100 per cent. This action cam doesn’t do that at all, it just gets blasted with sunlight, even reflected sunlight, and also when light gets into the wide angle lens it spreads around and contaminates the rest of the image. Sailboat masts that are painted white look like flat white glowing masts, even though to our eyes there is some shading of them. A white boat with plank seams on it comes out as a white boat with no plank seams. Plus, this camera does not appear to have any attachment points for filters to help us with this explosion of light.
.
It looks like this problem is caused by the wide angle lens and the relatively small sensor used to render the image. Longer lenses provide less opportunity for light to come in at an angle and bounce around in front of the sensor. Stills shot with this camera show the fish eye distortion around the edges that result from using such a wide angle lens. However, this lens was chosen for its ability to gather a huge field of view. It is not a precision lens to capture a specific frame of video, it is a shotgun of a lens to capture as much as possible, like a snowy mountain full of snowboarders. The fact that it did well in side by side tests with the Go Pro 3, 4, and 5 tell me that this is what you get when you get an action cam. Wide field of view and nuclear shots when the sun is forward of the lens.
.
Shots that did not have this extreme range of contrast looked fine, detailed, coming out of a little camera. I wanted some video software to attack the extreme contrast problem, but so far I have a simple video editor that won’t do any correction. I will continue to look for something.
.
I did find out that the settings for the still photos also applied to the video, color temperature, ISO, exposure, but they were inadequate to correct the lens flare, which is a physical thing happening before the light hits the sensor. Another problem is the camera weighs nothing, so although it won’t make your helmet droop to one side when you have it mounted to one side, it has no mass to dampen the jitter that action imparts to it. Some have described this as “jello”, the image jiggles as the camera jitters. Maybe this is why the Canon EOS feels like a brick, the mass keeps any jitter, even from the SLR shutter and mirror, from disturbing the shot. If you mount the action cam to a solid object it will still reflect any vibration. Normally the mounts have rubber donuts to smooth out the vibration, but these allow camera movement and at some point you have a harmonic oscillation, at some frequency of vibration the image will turn to jello.
.
On the other hand it is amazing to have 4K video coming out of this little plastic camera, and if the photographer can manage the image contrast, the videos and stills look fine, detailed, accurate. I guess there is a certain license to introduce some lens flare from the sun, some jitter, some “jello”, the same way ENG video was allowed to depart from the strict rules of videography, it imparts a feeling of rawness, action, real life, adventure. I was looking at some edited videos shot with action cams of an Aussie sailboat, the Superfoiler, or something like that, an awful boat to sail, but exhilarating, and the shots were real time edited. They had probably an action cam on each sailors helmet as well as several mounted on the boat. When you’ve been watching stuff like this you know when the lee bow goes under something is going to happen. The sailors are on trapeze’s and they are hit with a sudden deceleration and they swing forward and around, the boat begins to pitch forward, water is splashing everywhere, some land in it, some are bravely trying to keep their balance, but no, they too go under. Not sailing, mayhem. There was no lens flare in those lighting conditions.
.
So this sort of thing appeals to me in a basic way. Wish I would have had it long ago.

The android app that helped me so much is called quadcopter XG simulator. It is free and seems to accurately mimic actual control of a quadcopter.
.
I can't ignore my unfinished boat business and go out and fly a toy helicopter all day, mostly because it's battery takes 6 hours to charge and only lasts about 10 minutes of flight time. I will not give in to the urge to buy extra batteries, I will do what I can about twice a day for ten minutes and learn how to fly the thing.
.
I can't wait till the i60e camera comes in, it will be my first real action cam. I did buy a very cheap standard def camera that recorded onto an SD card, it was very small and did work, but the video was noisy and I only used it one time. The i60e shoots in 4K, which is supposedly 4 times sharper than HD, plus it shoots in most of the ordinary formats 1080, 720. If you are uploading videos to You Tube, there is no sense in shooting higher resolution formats only to have them compressed when you upload. Some editing and post software allow reframing, so a larger format will allow zooming or cropping of the video and still have enough left to fit the You Tube restrictions.
.
The next day the camera arrived in a small black box embossed with silver lettering. Elegant. The camera is very small. I am not used to Go Pro's or the other action cams, so I was surprised. It took a while to figure out how to go through the menus, how to link the camera with the android phone via wifi, and find out that there is no way to use the camera as a USB camera with a linux toughbook. There might be a way to bring HDMI video into the Getac. A micro SD card did not come with the camera so one had to be ordered. It was about 2/3 the price of locally available, so for just under 20 dollars a 128Gig card is on its way. No hurry. It will arrive in about a week. Free shipping by helping a fellow yardbird with an order that got us above the 25 dollar free Amazon shipping minimum. I am not a Prime customer.
.
The ThiEYE app that is shown on the internet must be for the iphone, the one for android does not appear to be the same style, the menu pages look different, I only tried a couple of things. I wanted to see how 720 at 60 frames looked. The camera will shoot at 120 frames and then you can play it back at normal frame rate and you have slow motion. Also 1080 can be shot at 60 frames and that gives half speed slow motion. The camera can be set at various time lapse rates to shoot time lapse video. It also can shoot bursts of frames like the EOS does.
.
The android app has quite a bit of lag to it, so the camera can be pointed at a new subject and it takes a while before the image on the phone changes. It might be a function of the age of my phone's android system. The 4k video will not transfer to the phone with the wifi app. To see it on the computer I'll need that SD card. The 128Gig card is the same size as the hard drives on the navigation computers.
.
Some research turned up that the camera shoots 4k video in motion jpeg format, which is an old clunky compression algorithm. If you'd like to know more about video compression I recommend going to wikipedia and search for discrete cosine transform. This search for more compression without losing quality has gone on a long time, it wasn't some brilliant person popping up one morning with the answer. As compression has become more and more attuned to our visual perception, more and more data can be left out, and we see what we think is the complete picture.
.
When you think about how moving pictures first developed with individual frames displayed at a rate just fast enough to look like smooth motion, and each frame was a complete photo of its own, and in 70 mm film each frame was about 3 inches across, there was a tremendous amount of detail being captured by the camera. Think about the optics and the film chemistry, the peak of film production required a huge investment in mechanical, optical, and photographic technology. That was about where I came into TV and TV was headed for videotape. The film chemistry was going out. The transfer of optical information no longer relied on an optical device at the delivery point. It was using a graphics display with an electronic input, the TV set.
.
Over time we saw TV cameras increase their signal to noise and resolution, problems with dynamic range were overcome with tricks. When HD quality video became available, the cinema look could be mimicked, but progress didn't stop there. 4k became the goal, 4 thousand pixels of resolution per frame. This was impossible for a long time, but now I have a tiny camera that can achieve that resolution, something that maybe a young videographer would take for granted now, but I am astounded. Of course this is not a camera that offers a lot of the tools we would like to have, no interchangeable lenses, not a lot of control of the image quality.
.
This is a camera that came out of the mountain biking and snow boarding culture, slap it on your surfboard and let it rip. Now the tiny camera can get shots that were impossible before. There are smaller cameras that shoot well, tiny tiny cameras. I was looking at a 720 camera with a built in 5.8gig transmitter that would fit inside of a small egg and it was in the 20 to 30 dollar range. I think if you go smaller the price goes up. You could place these high quality cameras all over the place, unobtrusive, and transmit the video to a receiver that cycled through the 5.8 gig channels. This technology is commonplace, and it's coming from China.
.
The question was, are you going to attach that camera to the drone and fly it, well, no, it wouldn't last 5 minutes. I kept practicing with the drone. I'm not very good at video games. My goal was to hover at first, just keep hovering till my reflexes would counter the wind or the fluctuations of the toy drone's prop motors and keep it level and in one place. The problem was there was a large boat in front of the communal kitchen where I could set the drone down and fly it without a lot of wind hitting it. The drone flew up and I could struggle with flying it out into the boatyard, tweaking it this way and that to keep it organized with room around it and no crashing into gravel. And now I came upon a difficult effect that I must relate, this is critical to newbie drone pilots, think of the drone as kind of a frisbie, a disc that can catch the wind and fly up or down, whatever its attitude, when the wind hits it, it will take off in some direction. In this case it flew up and I couldn't see it, it was behind the large boat, and I began running around, searching for it, I didn't want it to fly into the North River Marsh. Here's where my baseball skills, that never were developed, come into play, bystanders pointed up and exclaimed, the same way they might at a pop fly. I was in the same condition as the ballplayer who looks up at the sun and all is lost, only I didn't look up at the sun, I looked up at the Bugs drone, lost up in the heavens, I had no way of knowing which way it was pointed or what to do about it, it was way up there.
.
I didn't know what to do but my mind raced ahead of the situation, imagining the drone killing somebody innocent who didn't know the boatyard that well. There are a lot of new people coming in and asking "Where's Rocky?" or "Are you Rocky?", really. Fortunately Rocky and the main guys that work the boatyard were away at lunch when the impact occurred. I of course couldn't see it, looking up in the air on the South side of the communal building, while the drone, made of cheap Chinese plastic, was plummeting down at who knows what speed to the North where the expensive sailboats are awaiting their own launch. When I came around looking for it I hoped no one was upset or hurt. But what if I couldn't find it, I had no idea where it had landed. It could be shattered up on the deck of these many large strong boats. It came down hard, no control, like a rock, a Chinese lithium ion rock, to impact a random spot and then I would have some liability. The rules today say you have to have liability insurance when you come into a boatyard. I wonder if there is a clause that exempts coverage if a boat owner flies a Chinese drone and does damage.
.
I found the drone upside down on top of a deflated fabric dinghy. Good landing, no one got kilt. Was the dingy deflated prior or subsequent to the drone's arrival?
.
I brought the dremel-like Black and Decker tool to the woodshop, where the damaged drone was waiting for some help. It didn't take long to fair out the propellers, and then make sure the drone could still power up, just take it out and get it rotating, lift off, then cut it down. Enough.
.
Some had seen my exploits blowing up dust as I navigated the drone down to earth, then soaring up, out of control, what do you do now, correct, correct the correction, somehow get it down and idling on the boatyard. They said you are doing better now than yesterday, when did you get it?, two days ago.
.
The drone is now a veteran, cowering down in the woodshop, not volunteering for future flights. It will be harder to get the same performance from the engines that power the rotors. After the crash I just powered it up and did a quick lift off and then powered it all down. It could still fly.
.
When I put the battery on charge a puff of smoke came out of the little cheap Chinese charger. The charging light came on however and I hoped it would really be charging the battery. The next day revealed the battery had not been charged and when I looked at the little circuit board inside the charger I found a diode had burned up. It is hard to find components like this any more, no Radio Shack, and mostly surface mount components are used, not like this old fashioned diode.
.
I found a diode in a damaged Harbor Freight fluorescent lamp and soldered it into the charger. It did not fix the problem, we are grounded until a new charger comes in. The image is from saatchiart.com called portrait of Claude Diode, who are a techno-punk band from Sweden, and the artist calls himself Slow Pulse Boy. You never know what you will run into when you search on the internet.

I was afraid that the horrible cold of January would continue and give us a much longer and colder winter than ordinary. It has apparently let up, and what feels like mild weather now is more like normal winter weather here at the Georgia/Florida border. Still too cold for epoxy work, or that is the excuse I use.
.
My birthday came up suddenly and I received a nice gift from my younger daughter, a stuffed toy that she created and she calls them Puffington Pals. They are cute and everyone smiles when they see it. My older daughter texted me from England about sending me a Gopro Hero camera, but I said I wanted to do a little research on that first. I had been thinking about aerial photography with a drone and a Gopro or similar camera. So I began looking at drones and cameras and what people were using.
.
The Gopro Hero is considered the benchmark of action cameras, but the field is jam packed with many many alternatives, and some that are on par or even better than the Gopro. The drone marketplace is also large with many choices. I decided to get a popular drone called MJX Bugs 3. It does not have autonomous flight in any way, it is manual control by the operator only. It also was only $38 dollars with my credit card discount, normally it is about $65 and up.
.
In the camera department I looked at the Gopro Session which is the lightest Gopro action camera, so it would be more easily lifted by the drone. There are many You Tube videos of action cameras and comparisons, and even one with the Bugs 3 drone carrying a camera called ThiEYE i60e. I could see the video that was shot by that camera with that drone and I figured I could follow suit. There are comparison videos of the i60e side by side with the Gopro Hero and there's not much to choose from between the two, as shown on compressed You Tube video.
.
There are also videos of the high end of aerial photography using expensive and complicated octo-copters and cameras like the Canon EOS (no, mine is older and doesn't shoot video). These are machines with various autonomous flight systems, some maintain altitude, some have separate controls for the copter operator and the photographer. The cameras are configured something like the steadicam, having stabilization and a remote controlled gimbal. The prices for these drones start right at about a thousand dollars and go up to around 15,000. One was an octo-copter with eight twin motors that each had a prop above and below, 16 propellers. It is possible to get reasonably good video from the lower end drones and cameras but the platform won't be as steady and resolution and noise and distortion can creep into the camera's video.
.
I ordered the drone on the weekend and it arrived on Monday. It had to be assembled and its battery charged. When the light turned green on the charger is was a green light for me to go out and fly the chopper. It was a warmer or less cold afternoon, so there were more of the yardbirds gathered around the communal area and I put on an air show for them. Some air shows have tragic accidents, explosions, and wrecked aircraft, but this one had commentary disrespectful of the captain and pilot. It was very tricky just to get the thing off the ground, but then it would quickly resist any attempts at control, a wild whirring device with four blades, made in China. Flight time is thankfully limited by the battery expiring after 5-10 minutes. The chopper ended up on the roof once, sliding off to the ground, and only needing to be reset to resume its torture. Don't fly it into those stanchions someone exclaimed as I did just that, and still the little monster was ready for more. It ended up on its back, rotor blades digging the gravel of the boatyard, and finally it was spent, battery warnings coming from the controller and flashing lights on the drone.
.
I needed some flight training without wrecking a real aircraft, so I found an app to put on my android phone that would mimic the controls of the drone and I could fly a drone-like icon. When I crashed it, the phone would display, in red, the results of the crash, broken rotors, etc.
.
It helped. By my fourth session I could hover the craft and only crash it about a dozen times in 10 minutes. When I was flying it successfully there was no one around to compliment me. The image is from the internet of the drone, but with a different camera.
