RPi, Raspberry image backup to Mac

Updated 2018-02-14 !

This backup method will make a copy/image of the whole card even if there is very little data on it. So if the card is 16Gb, the backup file also will be 16Gb. On the other hand You can ZIP the image file to save space.

Another, maybe smarter ?,  backup method is described here.

After some Googling I found that other people have had the same problem and the issue is that the Thunderbolt cable is defect.

The thing is always to get the right spare part number which is 922-9941

So search with Google or Bing => "Apple cable 922-9941"

Some hints to exchange the cable is to follow the relevant parts of these instructions on IFIXIT

Empty the water system

Empty the fresh water system with compressed air !!

One of the things, when You head back to land with the boat, is to empty the fresh water system. I have got several instructions/tips over the years but the best advise I got is to empty the pipework with compressed air.

Some time ago I bought a handy Stanly compressor from Jula. Just below 10 Kg in weight including a 6 liter tank. Nice for smaller works

Unboxing EVE HomeKit products

Since the HomeKit app, Home, for iOS was shipped with iOS 10 it was time to check its possibilities.

After some checking the products from Elgatos Eve seemed to be a way to start. They also have a free App which I like. The disadvantage is that they are Bluetooth devices with a limited range and therefore have to be pretty close to an Apple TV.

I started up with the Eve Room, indoor sensor, and Eve Energy, switch and power meter, and the Apple TV 4 as Home hub.

Apple have god instructions here and there, read them, but first update the firmware of the accessories, in this case via the Elgato Eve app, otherwise the Home app will probably not recognise them.

Dishwasher servicecode 60

Our Husqvarna dishwasher QB 6221 stoped working and displayed the servicecode 60. The washer stops dishing and the pump empties the washer.

After some Googling I found some Guys who have had the same problem and it indicates overheating. It also seems that many modells from both Husqvarna and Electrolux shares the same control electronics.
