Updated 2024-06-30 ! OpenPlotter(OP), a Boat Navigation application, is really a nice and simple installation of OpenPlotter (OP) OpenCPN (OC) SignalK (SK)  and other supporting applications for Your boat. An overall information about the OP package is found  here   and you can watch the OP v4 progress  here .

Updated 2024-06-06 ! After having tested several methods creating a bootable USB SSD, or other USB drive, for Raspberry Pi(RPi) 3 4 and 5, I finished with this simple method Create the setup you want on a ordinary SD card(Or use existing) Make a bootable backup/clone of the SD card saving it to the USB SSD Remove the SD card and boot from the USB SSD Having a RPi 4, 5 ? Use this post on how to write the OS direct to the SSD.  

Updated 2024-06-05 ! Yes, it's really true ! Thats the maximum time it takes to write the Raspberry Pi(RPi) OS to a bootable USB SSD and maybe read this post ? If you have a RPi 4, 5 and a USB SSD or  other USB drive , that works as a boot media, just use  the RPi imager which can write the image direct to  the USB  storage. Having an older RPi ? Use this post instead. If you already have a SD card with working applications and you want to "transfer",  copy/clone,  them to a bootable SSD use this post .

Im using NodeRed together with  Speedtest by Ookla  but just the other day it wasn't showing the right data so it was time for "Bredbandskollen", the command line version. Bredbandskollen has always been a reliable source when testing internet speed.  I'm using their WEB-site and the iPhone app and it have always worked very well. This post will show how to plot data in a graph according to the picture.

Just the other day the backlight for our classic Raymarine E 120, Navigator(MFD), stopped working. It's from 2006 so I'm not surprised that things happen. You may wonder why we keep it instead of buying a new one but the thing is that we have 2 installed together with a well functioning radar so buying new stuff will be a hefty price tag. After some Googling I found out that the backlight is produced by a CCFL , a type of neon light, and can give up after some years. The Googling also gave some tips how to change to a LED backlight. The picture above is showing a test with a short LED light strip to verify the solution, with dimming working, and checking the health of the MFD.

Updated 2024-05-03 ! In Signal K (SK) there are 2 applications, in SK appstore, that can handle charts Freeboard SK (FSK) Tuktuk Chart Plotter (TT) FSK, preinstalled, uses the OpenSeaMap charts(OSC)  when you are online.  If you want to use offline charts or other chart resources you have to install " @signalk/charts-plugin "(CP)

In search of the optimal solution on how to interface our IVT Heat pump,   first try here , I stumbled over   a nice integration   for Home Assistant(HA). A first quick setup is shown at the right. The first obstacle was that it was HA which I knew about but never used.  So it was "back too school" and doing  a blog post  about a HA Core install.

If you are running the IVT Anywhere or the  Bosch Easy remote  app you probably also can  retrieve its data with for example NodeRed.  With the nice application  Bosch XMPP you can set up an integration with the cloud service supplied by your vendor.
