Bredbandskollen, Internet speed, CLI

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.

Raymarine E120 & E80 backlight failure

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.

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)
