Sorry hadn't read the guide. Still taught me a little about Linux in searching for a solution. A lot more to learn.........

I have uploaded the last changes and bug fixing to the github repository. If no issues are reported this will be the new stable 0.6.0 release. English and Spanish versions are done and we are working now on Catalan and French versions. To test do as usual:

Download the last beta release.

Create the SD and connect to internet

Open a terminal and type:

cd
cd .config
rm -rf openplotter/
git clone https://github.com/sailoog/openplotter.git

And test an test and test and test...

Next step: Documentation and 0.7.0 release. Or perhaps 1.0.0 final release?

Is that Uruguay instrument project on github somewhere?

Thanks for making this project a reality! I guess I'll never have to buy another chartplotter system!
This will do everything I need in the sailboat.

I allso have a coupple of dinghys and a skiboat. Could this software be used on a raspberry pi zero mounted on the outboard? Without openCPN offcourse.

compass is not needed (no radar or AP) but GPS for tracking , revcounter , cylinder temp and water pressure would be nice.

Anyone connected analog sensors to their pi?
any ideas on rev counter interfacing?

What sort of sensors are those on the top? My Spanish isn't that great. Obviously I don't think I'm the only one interested in making something like that.

Sailoog, you are seriously doing some amazing work with this. With this and SignalK.... It's bringing sailing to the common man!

Disregard, I found them:

I was looking up those sensors, and I wonder... would those even be good for a boat? Wouldn't the reading be way off if a raindrop fell on the wire used to measure the temperature to derive the wind?

I think not yet. I will suggest him to do it.

Yes, build some waterproof case, connect a wifi dongle and start the headless system from your computer/phone/tablet.

I am about to finish an industrial look waterproof case, I will publish here when is done.

Analog sensor is on the "to do" list (SPI interface) and the first application will be voltage and current monitoring. It would be great to hear rev counter interfacing ideas. I have saw cheap systems with magnets and some sophisticated optical system with a recycled computer mouse.

You are right. The prototype seems to work fine and now the challenge is waterproofing. It seems that the only part that needs to be in contact with air is the 4 little legs of each device. Maybe face down under a little roof is enough, we will see...

.

If anyone is interested, i did a little write up on how to set up a headless system here...

Feel free to find all the errors..

Also, on a different tack - signalK seem to have a load of updates on git in the past few days - anyone had a look?

I don't think the Pi zero would be a good platform for this. Not much processing power ( single core processor) and only 512mb of RAM. the Pi 2 has much more power and working memory and the formfactor is still very small.

Nice! I am working on documentation now, do you mind if I take pieces of your text? English is not my language and copy/paste is always faster

Yes you are right. But I think the Pi zero is a good option to headless systems. The only critical and demanding feature is the SDR-AIS decoding but I think you shouldn't have problems.

edit: I mean without running opencpn of course.

Feel free, it's nice to be able to help in any way

I'm still waiting for my Zero to turn up, but suspect if you are just looking at sensor data and not OpnCPN as described by manitu then the Zero should be able to handle it no problem at all. An arduino can do that sort of stuff running at 16Mhz.

Hi Sailoog and all,
I had some problems with openCPN following this update I made 15 minutes ago : heavy and slow panning and zooming, and as I insisted (strongly) it ended with complete crash. I couldn't read the displayed error message (looking like unknown characters).
After reboot openCPN presented same symptoms.
I then tried with my backup SD (one week old, or so), and then the behaviour of openCPN seemed OK as usual.
I will try again with the corrupted SD tomorrow to try to cacth more info...

PS : My OpenPlotter image was downloaded on 2015/12/17, I didn't downloaded the 0.6.0 beta3 again, as the site version is dated 2015/12/03 ...
