Seeing a list of the components and where to find them would be very useful! Thanks!

You have gone to a lot of trouble with the sealed enclosure there. Why do you consider this is necessary.? Corrosion on the Pi board or? I see many setups on boat without sealed enclosures for the Pi

I just picked up the same RPi case, nice and solid unit and enjoy that it has no fans. I went with the 4gb RPi, not sure if it was worth the extra. GitHub was a lifesaver for setting up guimods and configuring a 10” touch display.

Stop your video at 1:32 and in right bottom corner of the frame you have another header. You can put it on gpio pins before the hat

i have the same problem, i wonder why they made it like that, seems so stupid...let me know if you find a solution

in comparison to your i have a garmin 943x with radar, sonar, nmea etc. It's nice but maps are up to $250 (plus tax) It pull at least 50w when running. It's on a swing arm instead of hard mounting because I know it will fail eventually and then I'll have to fill the mounting hole(s).

Unfortunately the homemade usb cable you describe is not always reliable with all victron devices, I found you really need to use a Duppa isolated adaptor from Italy for total reliability, I saw this on Andys Off Grid Garage channel

I think you want your converter’s fin oriented vertically for best cooling efficiency

US charts you can download for free and you can download is strait in open cpn

I also added a Pi 4 with Victron 150/45 and ordered the wires like you suggested but my PI is at the front of my RV while the Victron is in the rear basement with all my solar stuff. I am going to try and figure out if I can do a wireless usb hub/dongle or ? not sure what will work for a wireless connection. Of course the PI has blootooth and WiFi and you would think that the Pi could read the Victron which is also Bluetooth. Kinda confused but wiring all the way from back to front really is not an option.

I think there is only cells in the middle only difference is that these have glass on both sides ?

I installed four 100W Newpowr bifacial panels this year to replace a regular Renogy 175W panel. They are tywrapped to the lifelines at the bow and fold down without interfering with the genoa when at sea. I can now keep 300AH LIFEPO batteries fully charged and keep the fridge on making cubes and keeping the ice cream cold. SV Renaissance 41' Beneteau

Hi Dave....I have a sailboat here in Brazil and I am an electronic engineer...I will be in Vancouver last week of august...could be possible to visit your sail to see the electronics ? I am doing the same here in in my one....

You're in me ol' stompin' grounds

5:00 for heat test, run a benchmark on the 4 cores, geekbench, extra tip you can lock down your pi os thru raspi-config, prevents logging wearing out the sd card. terminal, sudo raspi-config, performance options, Overlay file system => Enable or disable a read-only filesystem.

Hi, good video, have you looked into the Home Assistant integration with the BBN OS?

Nice work. I’m currently on a similar journey. Here’s how I did it. ruclips.net/video/bPhMNoLLRJw/видео.htmlsi=99j7r_1DRTcUUkJe

8:33 Couple of tips for you : - On your terminal, you can use the up arrow key to summon previously entered commands. - If you don't even want to bother with the arrow key, you can use the watch command followed by the actual command you want to monitor and it will automatically cast it every couple seconds for you. For exemple : watch vcgencmd measure_temp

I like the concept of BBN and I know the more options out there the better, but I prefer openPlotter for a few reasons : - Firstly OpenPlotter is just software, meaning it will run on differents OS and I'm not tied to a, although quite active, ultimately kind of niche OS with a small dev team that might just stop being updated at any points. Instead, I run openPlotter on Debian, which is never ever going to die. - Secondly, and this is more of a personal choice, I very much want to keep my nav systems the most stable and secure. That mean I want it to run only my sensors and instruments, segregated from every other electronics. So no music, no mail, and definetly no internet. - Finally, I work in IT, and so I can tell you that the openPlotter team spent a huge amount of time documenting their software, which is both extremely rare and extremely valuable.

Could you use a screen that uses the ribbon cable style for the touch? Sometimes I have issues with usb devices and PI to do with the rules and permissions e issues with u

another great vid

What are your thoughts on using a metal enclosure to mitigate emp from nearby lightning strikes? Aluminium would be less corrosion prone and still provide the fereday cage effect required. Also would have been better for transferring heat? But the lightning emp may kill everything in the box anyway as it'll travel along any unshielded wiring? Your thoughts?

Ha ha, first like. Are you going to put some silica gel sachets in the various enclosures?

Hi Dave, thanks for the video. Can you please advise if the Venus OS over raspberry have an access from anywhere in the world or just via internal network and how to make it accessible over the internet.

Great video..... thanks.... wanting to make my Cal29 digital with Raspberry Pi and related components.... cheers from SV The Lounge in Nanaimo.....

Dave I have found that using non isolated serial to USB made up leads work most of the time , but as you add more leads to more devices they will stop working, you need isolated serial leads, I brought a Isolated 4 port USB to TTL UART FTDI from Duppa that will run 4 devices via one USB device along with 4 made up leads cost me $100 AU, Also if you install the large image of Victron Venus you also get to run Node-Red and SignalK, SignalK is great if you have a boat as it is a standard protocol with a lot of boat comms

Dave, can you share what waterproof 13" screen you bought? And thank for sharing about the Pi5 and marine navigation! :)

Hang your screen on the underside of the compagnionway hatch. That way you can push it (almost) all the way open. Just my 2c 🙂

Watching this and some other videos, cool projects.

Would you please post links for all the parts you're using. Thanks.

Hi. Excellent video. Could you say what specific touchscreen you're getting? Thank you.

No problem James, your welcome I make less than $5 per month on You Tube, I do it for fun and to help people, there is another guy on RUclips named Will Prowse he does good videos on everything Lithium, I started by watching him and built my own lithium batteries from harvesting old laptops batteries check him out. If you have any other questions about batteries send me a direct message davethemmp@gmail.com

I have 2 12 volt Lifepro4 100Ah batteries for my 24V trolling motor. I need to be able to check how much charge the batteries have left while I'm out on the water. I currently have 2 standard 12v gauges mounted in the front of my boat that I had for my lead acid batteries. I have read that using the voltage only does not accurantly indicate how much power the battery has left. I would like some guidance as I am new to the Lithium batteries world.

This is so exciting to see!

Keep up the excellent work!

This is such an exciting development!

Great job on the Pi 5 sailboat navigation system!

Fantastic update on the Pi 5 navigation system!

Your dedication and hard work are paying off!

Keep up the excellent work!

Can't wait to hear more about the testing!

Wow. We're super honored at the shout-out! Thanks so much Dave!

Nice Video Dave!! I have similar heat results from My Pi 5, it seems to produce less heat than the 4 doing the same job. I bought a heat sink case (basically a big around the pi) with active cooler and it has never come on, I may have to hit it with a heat gun to make sure it is working!! With regard to the wire strippers and crimpers, my dad was an electrician and I inherited his ratchet crimpers and automatic strippers from the early 80's and once you have used them, you never go back!!

This is super fascinating! Can't wait to see this come online.

The active cooler for the Pi 5 is a game-changer.

Can't wait to hear about the performance during the heat tests.

Neat and organized setup you've got there.

Great job with the connectors on the outside.

I will be offering this as a turnkey build for anyone that wants open CPN on a Pi 4 or Pi 5, very low power consumption great for sailboats
