Qubino flush dimmer 1-10 V

We bought a nice LED lamp, Nemo Ellisse Pendant Double, which was said to be dimmable, but when receiving it there was a big IF  !!! 

The lamp was not "standard" dimmable, instead it was dimmable with 1-10 VDC or 100 Kohm potentiometer.

The 1-10 VDC control is common in big installations, in public environment, since it can control a lot of lamps with one dimmer.

Checking the lamp I found that the AC/DC LED driver was a Mean Well LPF-90D and in the drivers specification the second IF was found !!

The lowest control level didn't switch of the lamp

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.
