The Sailing Link

The yardbirds have asked me time and again have I been following the Volvo Ocean Race. I hadn’t. It’s kind of an extreme sailing kind of race, has nothing to do with us who are mainly cruising sailors and adverse to getting “hosed’ on deck, breaking ribs while down below, and occasionally being [...]

St. Marys Entrance

A test of both CF-C1‘s, one with solid state hard drive and 4 gigs of RAM, the other with 6 gigs of RAM and a regular hard drive, came out with some benchmark processes faster on one, some on the other. While playing around with them I received questions about OpenCPN, the navigation software. I explained that the GPS input enabled the program to put a red ship icon on the displayed chart at the position given by the GPS, and the AIS receiver enables AIS contacts to be displayed on the chart also. In the above image Kaimu is shown on the left side, in the boatyard on dry land, and buoys 16 and the sea buoy are shown on the chart as diamond shapes to the right of St. Marys Entrance.

Universal Port

I had to order the deep cycle batteries for the port hull. Right now there is an old group31 AGM battery and Trillium’s group 24 wet cell battery hooked up to the solar charge controller. I guess they are charged up full by now. I planned to install 4 group 27 AGM’s just like I have in the starboard [...]

dAISy meets U-Blox

The idea was to make the most of the difficult weather pattern coming in, tropical depression maybe, thunderstorms predicted for every day. This has happened before here, and we sit around with our work areas covered from the rain, no way to get any work done. But I have some inside work to do, so [...]

dAISy Test

I noticed I was more active and anticipating the work day with more of a positive attitude. “Attitude is Everything, Dammit”. I’m not sure why I feel this way, maybe it is getting past the big bottom repair/repainting stage, or maybe it is the ETL, estimated time to launch. June 28.

Patriotic

The red ablative bottom paint was very thick but mixed up easily in a few minutes. The top edge of the red paint formed a boot strip with the top edge of the blue hard bottom paint above it (3 inches). The edge was masked off first with Fine Line masking tape, then the masking was widened with cheap [...]

Capn Andy/chilly winter
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.
