The completely open plotter

[Jubilee39]

Got the Raspberry pi B+ Formatted 32 GB sd card, copied Openplotter NOOB. Inserted card into Pi, powered it up waited for android tablet to recognize openplotter connected via VNC seemed to work okay. now to add charts. Put SD card back into PC it is now labeled recovery and capacity is now 2.84 GB, What happened. How do you put cm93 charts on the SD card. I have a lot more to learn but seems I am stumped on the basics.

Another 32gb sd card did the same

Take an usb card reader/writer and connect the reader to the RPI. Then you can make a back-up copy of your system with the build in RPI copy software.

Adding cards can be done via internet Download. Or simply by putting the CM93 cards on an usb stick. Put the stick in the card reader and copy the charts to the Chart directory on the RPI.

I'll try that but any idea why my SD card format changes?

Hi Jubilee39,

the image of OpenPlotter is using Ext4 Linux format. If you use a Windows system. Windows can not use Ext4 format. However Linux can use Windows file formats. Therefore an usb stick (with windows file system) s readable by the RPI.

Your SD card is readable on a Linux system or the RPI.

The easiast way is to use an usb stick for transfering charts to the RPI Chart folder.

Not a large pump (volume is unknown to me), but I see current in typical usage eclipse 10amps. It's driving two Vetus MCT72 rams. The ACU 200 which is my current controller can pump out 15 amps continuous, while my old Ctrek unit pumps out a little more. It is nice to know the power is there if needed, and gives the option of upgrading.

The pypilot hydraulic controller can manage 20 amps continuous, 30 amps for a few minutes, and 50-60 amps for a few seconds. Continuous rating is measured and tested for safety and efficiency, but in practice the duty cycle ranges from 5-40%.

If the duty cycles is above 50% to hold course, the system is overloaded and won't steer well. You need to reef, or get a stronger drive.

So I love this idea. I have something sort of similar. I use a windows 10 tablet connected to a usb hub with serial connections to my Raymarine ST1000 autopilot and a GPS device. The tablet runs Polar Navy (I find the performance much better than OpenCPN and at $15 a year it's not expensive). I do need to run a usb cable. I originally had it set up with a wifi usb hub but the issue was I couldn't connect to that and tether to my phone at the same time.

I thought about the PI and such but the performance was frustrating since I find opencpn slow on a desktop.

The tablet is on a swing out mount I am really happy with so it can be viewed in the cockpit and also swung around inside. The nice thing is I can tether to my phone and use it for internet, netflix, etc.

I'll post some pics when I get back to the boat.

Can you configure an Android to run the code. You already have the screen and you can project onto a larger screen through a blue tooth connection or a software app.

If you are using Windows or Linux get to know how to use SSH to transfer files over Ethernet. On Windows there is a great free tool called WinSCP that connects to a Pi or any system running sshd. You never have to move the SD card around.

SD Card format for copying files between Win & RPI

TDan's suggestion for SSH transfer over ethernet

WinSCP

Looks very easy.

I was using a netbook running Seaclear II with the original display replaced by a PixelQi display. They have gone out of business, but they made a wonderful 10.1 inch display that worked like a normal color display in normal or low light, and an almost paper white display in sunlight. The brighter the better!
Backlight turned off for very low power. The only time it was hard to read the display was if you purposefully held it so the sun was reflecting onto it over your shoulder.

You might find one on ebay.

You should hang out with some of the catamaran crowd ;-)

Brilliant. The link through to the shop showed 3 amps (though Sean did say he can build higher powered ones), do you have a link to the 20 amp one you've seen?

Thanks.

Wow, that's a load of work!

Have you checked out openplotter yet? Signalk does so much now with numerous plugins for a host of kit and functions.

I've gone on to using influxdb for logging and chronograph for plotting, easy to set p and signalk has a plugin to send data to influxdb.

Signalk is the future!! We hope.....
