Raspberry Pi qtVlm setup on board with AIS via wifi
I have tried the setup onboard and have found some areas that need adjusting for the mounting - the french cleat works but it needs some additional support for when the boat heels and also bangs or pounds as I am sure it will -
I am going to redo the bulkhead part of the french cleat with some slots to keep the units support board more secure, using the same shape as I did for the desktop stand - maybe adding some slots to the mount to stop the unit sliding sideways when the boat is heeled. The positives of the system is that the wiring to the left with the USB socket powers the raspberry pi well and the small plastic distribution box has a on off toggle to turn off the RPi and also has a 12v socket to power the screen - I have also added XT60 connectors that will mate with a fan, the ghetto blaster, 12v LED red green nav lights that can be fitted to the mast in case the masthead lights fail, as well as anything else that needs a 12V supply.
The only downside is that the USB socket in this distribution box has blue LEDs while all the others in the boat are red - not a biggie but it would have been perfect if they were red - next time I will take better care when ordering.
Another positive is that he data from the ONWA AIS is really simple to send to the qtVlm and openCPN programs here you see it on the RPi qtvlm & opencpn and on my old android mobile phone opencpn so there is 3 redundancy options ONWA chartplotter ,RPi and mobile phone
qtVlm is a super powerful program you can load gribs, polars, charts, ais data, NMEA integration, it does routing and tons more and is regularly updated. It comes with a pdf manual and although the learning curve is quite steep it is really worthwhile to take the time to work through the manual and try it - there are also youtube videos which showcase the software with tutorials on its features. It accepts various types of charts and the developer has charts which can be purchased. You can use S57 S63 CM93 and MbTiles and raster charts in KAP and Geotiff.
It is available in Windows MacOS Linux and RaspberryPi Linux versions with paid versions to unlock features on Windows Tablet and and paid vesions for Android and IOS devices from the relevant app stores.
I have been using Linux for years- over 25 years but I find that it has got easier and easier and on the RaspberryPi 4 I can have a really low power consumption computer that is extremely powerful and runs really well and boots very quickly.A bonus is that when you boot up your computer while connected to the net it tells you there is a newer version and you download the newest version and with a few lines of linux command line commands it replaces the old version with the new version while keeping all your settingsand chartsetc. intact. BRILLIANT
