I really enjoyed your video, the Opencpn and Raspberry Pi is an amazing chart plotter. I am assembling a Pi4 for my boat, waiting on the big brown truck. I will have the AIS also, we have a lot of commercial traffic in our sailing area so I decided on the AIS. Many thanks, I learned something from you. Appreciate it! Jay

I am glad I was able to be of help to you. I am launching my boat in about 10 days and will do a video then about how well the system works. I currently only have a Pi 3B+ and have discovered it doesn't have the computing power to do course up. I am also planning to download the Radar Pi add on and try the plotter with my radar. I suspect I may have to upgrade to a Pi4 for that.

Very well explained every word mister. The best for you and your journeys

Yes it works well. The only issues are that the Raspberry Pi touch screen is no gt in direct sunlight and it is NOT even water resistant. I also went from plugging the power supply into a small inverter to buying a 12VDC:5VDC converter with 5 volt output to use as a power supply. That worked well. A big plus of using the Open CPN software is that you can easily download full official NOAA digital charts for anywhere in the USA for free. That makes it easy to add new charts and to keep your charts fully updated. I also took along a USB keyboard so I could use the Pi as a computer. Thanks for watching.

Thanks for the kind words. I am glad you found the video useful. I am planning an end of season video in which I will discuss how well the system worked. Before putting one of these home made systems on a sailboat, be aware that the unit is NOT waterproof at all and must be mounted where it can not get wet ever.

These SBC are very cool. Have media server and client ( TV side) running in my home for the last 8 years or so. About a year ago had ADS-B running to track aircraft. One of the nice things about Pi are the number of projects available. I like the idea of no fans and no moving parts. Cool project. Stay safe

I made one of these last spring and use it on my Catalina 22. Works fine -- for the most part, once you get it setup you don't really need to touch the screen much. It's not 100%, but it's a lot cheaper than a full-fledged chart plotter. When I say not 100%, I mean sometimes the touch screen can be touchy and you have to try a couple of times to get it to do what you want.

I used mine last summer. It worked well. The touch screen worked OK except that because of the size of my fingers I found it difficult to make menu selections since my fingers often touched more than one selection at a time. Other than that the system worked well for me.

I loved this video, Todd. This just may be the ticket for my new sailboat I presently have under construction here in Milbridge. My sailboat build is a bare-bones project, encompassing quite a bit of re-purposed wood and self-fabricated components. I'm now finishing up the fabrication of a Mantus-Rocna anchor clone (I've been posting this series on my KZread channel). I think your chart plotter project will blend in beautifully with what I'm presently doing. When this COVID-19 thing is finally past and back to normal, perhaps you'll allow me to be in contact with you to "pick your brain" if necessary. I'll be making trips over to West Marine in Southwest Harbor anyway after life gets back to normal!

Great job. Fantastic value for money. I'd love to know how much RAM you'd need with a Pi 4 to get the vector charts running well? I suppose it would still work out a lot cheaper than the crazy expensive Garmin devices. Apparently you can hook up the boat instruments to the s/w as well with a multiplexer or wifi bridge.

Yes the open plotter software lets you connect pretty much all electronics to the Pi. I never tried the vector charts because I had an issue with them not scrolling smoothly on an old Acer 10" netbook. That said, I think the Pi with 4 or perhaps 8 Gb of ram is a faster computer than my old Acer. It would be easy to try since you can download the vector charts free. Thanks for watching. One thing though. This little plotter worked fine on the bridgedeck of my trawler style powerboat's enclosed helm. The screen is no good in direct sunlight.

Thanks, Todd. Great video! How does it work when mounted on the boat? Is the screen sufficiently bright for sunlight, and how does the screen work when your fingers are wet? Is the system rugged enough to be sitting on the bulk head in the cockpit of a small sailboat? Those are my main concerns.

This screen is not a good choice for direct sunlight. My use for it is aboard my 1936 wooden powerboat which will be going into the water next week.

@@todddunn945 hey, openplotter is a lot more, it has signalk, node red, ais receiver that can send ais info to OpenCPN for example, GNSS, can directly connect to sensors such as I2C or SPI. Effectively it is the heart of your boat network that can collect and forward information from other boat systems to OpenCPN. For example, if you have a NMEA 2000 compass or wind sensor, it can collect that data and then make it available to see in OpenCPN as well as other chatplotters. I use it to take boat data and then send it to a separate home automation system. There image and NOOBS files install Raspbian with Openplotter and OpenCPN already in the image.

Furthermore the connectivity of Open Plotter is simply the connectivity available under Open CPN. At least that is the way I understand it. I could be wrong.

@@todddunn945 It's more like a complete set of tools, of which OpenCPN is one. Openplotter also serves as a data hub and multiplexer for various on-board sensors and transducers for wind, barometric pressure, depth, speed etc. The data can be used for navigation, but also to drive an autopilot. And although booting directly into OpenCPN is optional, it's not enabled by default.

That is great. Very clear instructions. Had no idea you could put something like this together, especially for so little. Is OpenCPN the only thing that will work with the Raspberry Pi? I fiddled around with it some years ago on my laptop and found it a little cumbersome.

John, I am aware that a Pi with more ram would be better, but the 3B was what I had. That said, OPEN CPN runs fine on a 3B with 1 Gb ram. I have been using it as my navigation system on my boat for two years without any issues. I have tried to set this up on my 4 Gb 4B and my 400, but Open CPN has recently had a glitch for loading the program. Hopefully they will fix it soon. I don't have links, but the only parts were the Raspberry PI, the Raspberry Pi 7" touch screen and the case. All are available on Amazon. You do need a mouse and keyboard for to load the program, but not to run it. Thanks for watching and commenting.

It is all in the video. There are five components. 1) A Raspberry Pi single board computer. I would use a Raspberry Pi 4 with 4GB of ram. Buy from any Raspberry Pi seller. 2) A micro SD card (16Gb or bigger) to put the operating system on. Buy any place that sells SD cards. I can buy hem at the supermarket locally. 3) A Raspberry Pi 7" touch screen. I used an official Raspberry Pi 7" touchscreen bought from the same place I bought the Raspberry Pi computer. Actually any screen that is compatible with Raspberry Pi will work. At home I have a 24" 1080P monitor connected to my Pi. 4) A case. I used a case that holds the screen and computer from Smarticase.com. I bought it on Amazon. 5) A power supply with a USB 3 output. On my boat I used a DC:DC converter with a five volt output that I wired a USB cable to so I could run the plotter from the boat's 12VDC main battery bank. You will also need a mouse and keyboard to do the actual programming and loading the Open CPN software onto the system. Any bluetooth or USB components ill work. Also if you want GPS functionality you will need a GPS receiver. Any USB GPS receiver will work.
