You need a system with NMEA output. If you just have an analog signal, the conversion would need some effort and know-how. My wireless NASA reveivee has a NMEA0183 output which feeds the CLIPPER displays.

I did several videos for specific components, e.g. SignalK. But I think every sailer needs to find the right setup specific for his purpose. So, my goal with my videos is always helping to help yourself.

As I started on my boat there has been no PI5. And as MacArthur was published, PI5 was not fully supported. This changed with OpenPlotter 4.x.x. The advantage of a PI4 is the lower power consumption. And the PI4 is fast enough if you don't use OpenCPN. So, currently the PI4 is fine for me. What power issue are you referring to? The PI4 takes 3-5W on my setup. I have a LiFePo4 running, so, no worries.

​@@Sir-Realthanks for that. I expect actually a bit more. Do you have some documentation about the cabling battery to pi ?

@@VK-qh6pr Since this year I am using the MacArthur HAT with the additional 12V supply PCB. This makes life very easy. Here you find the docs regarding the 12V supply: macarthur-hat-documentation.readthedocs.io/en/latest/power.html

I use Navionics on my tablet but on OpenPlotter you can get 1) OpenCPN 2) avNav

Watch as many utube vids on setp as poss. I run opencpn on openplotter and signalk which is fairly straight forward without any coding knowledge. Read the opencpn manuals, install the latest software and document your install and config so it's repeatable...good luck!

That is a quite open question. What is you goal? Do you want to replace a plotter or just getting AIS in? Take a first little use-case, e.g. forwarding AIS, and start your journey...

@@Sir-Real I’d like to use it for a chart plotter, a hub for all NMEA 2000 communications, ais, and eventually auto pilot and security. My boat is 4 hours away so this gives me something to work on when I’m not at the boat. I am at the step “plug power cord here to turn on”. So, I got a long way to go.

@@nutsandbolts432 Plugging in power is a very important step ;) Well, you need to find you own way. I personally started with a non-desktop Rasbian, playing with GPIO and I2C, later Node-RED. I didn't use the desktop environment for a long time. This changed now with the OpenPlotter setup on my boat, but I think it was a very valuable learning to work on prompt level. If your main target is to get OpenPlotter working, you should start with a ready-to-use-build of the OpenPlotter page and go from there. But - there are many forums which will help.

I am note sure what you are actually asking. You want to forward the data via TCP? This is something which can easily be done inside the "home-network". We did it in one video with Node-RED instead of KPLEX for multiplexing NMEA data...

uff, gute Frage. Also ich würde mal sagen, das sind sicherlich 15-20 "ganze" Tage gewesen, also einige Wochenenden... wenn man alles zusammen zählt.

@@Sir-Real Super, danke!

I don't think so - the DPI screens are made for PIs, not for Picos.

Ich kenne deine Wetterstation nicht - wenn die Station eine Schnittstelle hat und man von ihr Daten abrufen kann, klar. Aber dazu müsste man das genauer angucken. Die Frage ist, wie gut die ist. Ich würde eher auf Sensoren setzen und Wetterdaten ziehe ich von OpenWeather.

Du meinst die Richtung vom Lüfter? Vermutlich geht beides - Überdruck oder Unterdruck halt. Aber ich denke raus lüften ist sinnvoller.

DOH! It's instrument panel ! 😊

Not yet - I finished this project before summer vacation and I love it. But I had no time to summarize all the stuff - even if this is really the coolest thing on boat-connectivity so far for me. I love this dashboard/instrument panel. But if I find time, I will do some detailed assembly vid.

So ganz verstehe ich das noch nicht was du meinst. Was für eine Strombegrenzung? Oder meinst du die Spannung? Strom können LiFePo4 Batterien ja recht gut ab, können lange bei hohen Strömen geladen werden. Und das BMS schützt die Batterien sowieso. Ich denke nicht, dass man sie direkt beschädigt mit AGM Reglern. Das Problem was ich deutlich machen wollte: Man lädt sie nicht ideal. D.h. entweder werden sie nie voll, aber auch eine Erhaltungsladung mögen LiFePo4 Batterien nicht. Beides würde ggf passieren. Sie werden nicht zerstört, ich finde sie aber zu teuer für eine reduzierte Lebensdauer. Man fährt ja seinen Motor auch nicht immer bei falscher Drehzahl, auch wenn er nicht direkt kaputt geht. Und genau, die LM muss man durch Strombegrenzung schützen.

Hi, It has been years that I did this video and at that time I didn't upload the code to GitHub. So, I guess I just have a backup somewhere but not a accessible version installed, sorry.

Interesting idea, hands on event. But this would take a larger team for planning and conducting. But could be funny!

I use OpenPlotter currently as a dashboard only (plus NMEA multiplexer). It shows position, time, wind speed and angle, boat speed and my solar data (charging current,.voltages).

Uh, das Video ist jetzt schon ein paar Jahre alt, aber kurz: Das ist ja ein Bus (I2C), die Sensoren werden einfach parallel geschaltet... also ob ein oder 2 Sensoren ist egal, einfach parallel. Nur man muss darauf achten, dass man einzigartige Adressen auf dem I2C hat, d.h. die beiden Sensoren benötigen jeweils eine Adresse. Das kann man nicht bei allen Breakout-Boards umstellen.

I would use the MacArthur HAT and the IMU connector: macarthur-hat-documentation.readthedocs.io/en/latest/i2c.html#internal I am now using an ICM-20948 instead of the MPU, which seems to work pretty well with PyPilot: openplotter.readthedocs.io/en/latest/pypilot/imu.html So, you get a lot onboard without spending too mich energy in low level sensor integration.

Tatsächlich benutze ich selbst kein KPLEX mehr. Wenn du nur einen schlanken NMEA Multiplexer benötigst, ist das mit Node-RED sehr einfach und verlässlich machbar. Dazu hab ich ein Video gemacht. Damit bin ich die letzten Jahre wunderbar ausgekommen. Wenn du OpenPlotter nutzen willst, dann ist Signal K inzwischen das Herzstück und bietet (unter anderem) einen TCP NMEA 0183 Multiplexer per default auf Port 10110. Alle NMEA Signale, die irgendwie in Signal K landen, gehen direkt wieder raus auf 10110, so z.B. auch AIS, was man dann mit dem Plotter abgreifen kann. Oder man liest direkt Signal K auf Port 3000, was z.B. OpenCPN könnte. Kurzum: KPLEX kann man durch diverse einfache Lösungen ersetzen, je nachdem was man braucht.

I was dealing with this question recently, because websockets e.g. via a Raspberry Pico are possible, but not that easy. The REST API is limited as discussed - BUT: You can use TCP and even UDP connections to send data w/o using Websockets. I decided now to use UDP to send some simple sensor data. You need to add a connection in Signal K, UDP with Port, and you can send data quite easy (fire and forget). However, not very safe, nothing you can use if you system is connected to any Internet. But it is something I would love to add to my video as this is a valid way for some systems. If I find time, I will do it ;)

Hi Sebastian, I can't assist on coding questions as this needs some work, e.g. setting up a similar system, often the OS has changed if we talk about older videos, updates and I might even not be in this topic that deep anymore. So, I always recommend to publish your code in according forums to get help on coding level. A little hint: ENOENT means Error - no entry (found). If I see /dev/BLABLA we are talking about devices which must exist on Linux level in the dev directory. With ls /dev you will see devices existing (on command line). But: I2C is usually not existing on that level, only UART etc. if you realize the I2C connection e.g. with a library on Node-RED.

@@Sir-Real Thank you for your reply. The problem was due to the use of the docker container (for NodeRed), it did not have permissions to access I2C. After reinstalling NodeRed without docker, everything works fine. Thanks.

Everything that's easy is easy because enough people did it the hard way, so that the process became smooth

Full flexibilitiy is usually killing the plug and play feeling which you expect from UX optimized mass products. On the other hand technical creativity is offered with these kind of open source solutions. I think both own their place. What has changed compared to prior times: Today it is very easy and cheap to integrate sensors, displays, to generate dashboards, send mails or forward data... 😀

Keine Ahnung. Muss ich gucken. Why?

Don't you think that this is now trapped in a layer of Epoxy which we used the glue the foam in?

@@Sir-Real yes it is! But it still there mold and it will eventually bleed out. If u start w/a clean surface free of contamination it would have probably outlast the rest of the ship!

Thanks for sharing this. I was not that disappointed with the Pimoroni lib and wondering that the 1106 was more powerful, but if I have time, I will take a closer look.

@@Sir-Real Yeah, check out the framebuffer library for it. it's suuuper easy to do something like this enabledSprite = LoadSprite('enabled.PBM', width=16, height=16) def LoadSprite(filename, width, height): # print(file) with open(filename, 'rb') as f: f.readline() # magic number f.readline() # creator comment f.readline() # dimensions data = bytearray(f.read()) return framebuf.FrameBuffer(data, width, height, framebuf.MONO_HLSB) you now have a sprite you can reuse very efficiently at any time and it is any arbitrary size. the PBM is a tiny single sprite file (the PBM contains a little bit of metadata that you could use as well but I don't bother personally) display.blit(enabledSprite, x, y, TRANSPARENTCOLOR, COLOR) the above is the biggest thing that seems impossible with the pimoroni pico display. read through a few long threads of people talking about it but none have conclusions. with just this and the primitive shapes (line, fill_rect) you can pretty much do everything! and very efficiently

😜 I wait with renaming until Rapsberry 6 😜

Also in meinem Setup ist der DC2DC nur an, wenn die Lichtmaschine an ist. D.h. du kannst deinen Regler an die Starterbatterie hängen, aber der lädt dann nur die Starterbatterie und die ist normalerweise nicht leer. Der Lithiumbatterie hilft das nicht. Alternativ müsstest du den DC2DC immer einschalten, das ist nicht mein favorisierten Setup, genau. Aber manche machen es so, ich sehe da nur die genannten Nachteile/Risiken.

Ist ein 2002er 😉

Hi, Wollte ich schon so lange machen, aber komme nicht dazu. Dabei sind wir längst fertig und zufrieden ;) Ich mach das nochmal. Aber wir können uns trotzdem gerne austauschen. PN gibt es hier ja leider nicht, aber wie erreicht man dich?

@@Sir-Real Gute Frage, leider hast du keine Emailadresse für deinen Channel hinterlegt. :-)

Ja, damit man da nicht ständig SPAM bekommt. Aber ich kann eine Einmal-Adresse sharen und dann tausachen wir darüber unsere richtigen Mailadressen aus. Ich hab aber jetzt angefangen, den Refit in einem kurzen Video komplett zusammen zu fassen. Das sollte nächstes Wochenende fertig sein und online gehen...

Several years under the California sun and it still looks new.

I hope so. I think Peter did chose it carefully. Let's see if someone has got MAIANA installed for a while and can share his experience here

It is. But you need a (generic) radio approval. This has nothing to do with AIS. All radio systems, which are sending, need it.

@@Sir-Real Ah I see, it's because the device hasn't got necessary approval, thanks

Is there a list somewhere of devices that are approved for AIS transmission in EU? I am struggling to find a list anywhere.

@@kenkrige1594 I don't know. However, usually all "offical AIS" transceivers which you can buy in online shops for marine stuff are registered. So, it is a special case here that we talk about rather a project instead of a product thing.

Of course. I will add this also in the description: shop.openmarine.net/home/15-maiana-ais-base-kit.html

Man benötigt eine Funkzulassung, das hat nichts mit AIS zu tun, wenn man Geräte in den Markt bringt, die aktiv senden. Ist leider etwas bürokratisch und daher für offene Systeme etwas schade. Also es geht nicht explizit um Schifffahrt oder AIS, sondern um die Funkzulassung grundsätzlich

Thank you so much for your nice feedback! Really appreciate that! PS: But you need to call it PI not Pie, so that the Raspberry guys do not think they create cakes 😀
