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).

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 😀

You can define levels of security for MQTT. If you need encryption, authentication etc. But I can't help in detail via the comment section, best is to post your code in a forum.

I am now using the ICM-20948.

Not 1:1. This Micropython script is made for the pico, using the pico pins and pico libraries. Of course the basic principle can be translated to any PI but you need to exchange the libraries and take the right pins etc

Es steht zumindest auf der offiziellen Seite der MacArthur HAT. Also ich hab es nicht getestet, aber davon würde ich ausgehen, dass Seatalk mit der Pi5 nicht funktioniert.

@@Sir-RealDanke Dir! Ergo könnte ich den HAT nur mit dem pi4 nutzen. Oder einen anderen multiplexer e.g. Miniplex von ShipModul "einschleifen".

@@carstenholyshit5066Geht es dir um Seatalk oder um NMEA2000? Das sind ja getrennte Eingänge und gelistet ist nur Seatalk. Ich vermute die MacArthur wurde für den PI4 entwickelt, dann kam währenddessen der PI5.

@@Sir-RealIch überlege einen Raymarine ACU-400 anzuschaffen und möchte aber gerne meine ST60 Geräte und die ST7002 Bedieneinheit weiter nutzen. Ergo muss ich ST1 nach STng bzw nmea2000 wandeln. Ich will mir aber nicht diesen ITC5 Wandler von Raymarine verbauen. Diese ganze Produkt Abhängigkeit schränkt nur ein.

You need to set-up your system to use the SPI interface for the MCP2515/MCP251XFD and get some CAN nodes installed in Node-RED. As I do not have a NMEA2000 instrument here I didn't do it so far - but check this quite similar post here: forum-raspberrypi.de/forum/thread/59776-mit-node-red-can-bus-lesen-und-schreiben-mit-dem-rs485-can-hat-modul-funktionier/

Never mind the help. I figured where to generated the API Key. Thanks for thinking of responding! 🤨
