Installation Linux Ubuntu - Part 2
The hard disk can be divided automatically or manually. The language for the installation can be selected from many different languages. Installation Linux Ubuntu
The Acer ES1-331-C0YK bought in the middle of May 2016 will be equipped with SSD and more RAM in July 2016. On the SSD, Linux Ubuntu 16.04 is installed. Planned Obsolescence by Windows
My first Linux Ubuntu test: I discover an icon with ''Simple Scan'', let's see what happens when I connect my old scanner from 2004 to the notebook. Surprise! Layout for very large screens, 2280 pixel and more width
The only difference to the full-HD layout: the block for own ads moves from below the navigation left to an own column right. Layout for full HD and 1880 to 2279 pixel width
The whole content is in 2 columns. So there is less to scroll on a full-HD screen. SXGA and screens from 1200 to 1879 width
The standard layout of our pages, until the adaption to different screen sizes. XVGA and screens from 1000 to 1200 pixel width
Now, the navigation has place left from the 600 pixel width content. Both 160 pixel width ads move below the navigation. SVGA and most tablets in portrait mode
From 795 to 999 pixel width, it is possible to show both 160 pixel width ads richt from the 600 pixel width content. Layout for up to 794 pixel width screens, most cell phones
The page is zoomed, to show the 600 pixel width content over nearly the total screen width. 15 pixel border, at less than 360 pixel only 4 pixel border. Change the battery in a lyceum
You have 2 batteries for Your notebook, but how do You exchange them, when You sit in a liceum with no plug in reach? Supply from the sun
While I make my test with 2 connected notebooks, all 3 photovoltaic modules, deliver together 2.74 A at 14.2 V. 39 Watt are little bit below the demand. Run several notebooks by the sun
As long as the notebooks do not charge the internal batteries, 85 Watt are enough for some economic notebools. Here is my ASUS UL30A connected by a car adapter to the 12V outlet. 3 photovoltaic modules to compare
One hour later 8:40 am, it becomes cloudy. Opportunity to compare all3 modules, how much they deliver at cloudy sky and still not so high standing sun. First full sunshine in the morning
41 minutes later, the sun is now above the trees and the solar yield is first times greater than the demand from notebook and cell phone. 1.59 A times 13.8 V gives 22 Watt. Sunshine early in the morning
6th July 2012. A little bit sunshine through the tree-tops. I have all 3 photovoltaic modules with meh, becuase I want to test using 2 notebooks. Length of cable is not enough
The distance between a place in the shadow to work and a sunny place for the photovoltaic to deliver electric power can be larger than thought. What does the MPPT with 12V AA Mignon cells?
From 2010 until today, I used 12 AA Mignon rechargeable batteries for my solar power supply of the notebook. Here an experiment what happens when this batteries are Battery full shows MPPT procedure
There had been just 13.86 V and 2.27 A. Suddenly, the display changes to 17.49 V and 1.13 A gives 19,67 Watt. This change is the proof for the MPPT procedure. 34 W foldable photovoltaic
The 85 W control unit stands more than a single 20 W modul. Here I connect my foldable 34 W Unisolar from 2005 and the new foldable 20 W foldable from the solar set together. 20 W foldable photovoltaic
It's July 4th 2012, the photovoltaic is full in sunshine, but 13.47 V times 0.86 A are only 11,58 Watt. Not optimal oriented towards the sun, a little bit warmer. Test with Vanson 70W car adapter
The Vanson SDR-70W is designed for normal notebooks with a higher electric power demand. Compard to the direct 19V outlet of the solar set. Test with Belkin 40 W 12V DC 100-240 AC power supply
The Belkin F5L065 is speciall for netbooks and economical notebooks like my mein ASUS UL30A. Here the conversion loses compared to the direct 19V outlet. Solar set with 19V outlet for notebooks
The 19V outlet of the photovoltaic set for notebooks increases the efficiency versus a 12V outlet and a car adapter for the notebook. Efficiency of AA battery charger
At calculating the energy usage, it's easy to look over the efficiency of diffeeren processes. Or who would have thought, that this AA battery charger just needs 10 W? Solar charger for camera batteries
Most chargers for batteries from video- and digital cameras can be used with 12V. At the 12 V output of the solar set is a car-socket. Test photovoltaic set for notebooks at the rivulet
After 15 years hauling a lead battery, after 2 years too weak NiMh buffer battery. July 4th 2012 starts a new age of notebook outdoor usage. Charge solar set by a notebook power supply
The 85W solar set can be charged by any notebook power supply as far as the plug fits and the power supply can deliver 60 W. scope of delivery  85W solar set
After You have taken out the foldable 20 Watt photovoltaic of the box, You find below: Left top: control unit with 66 W lithium-ion battery, middle top: 12V LED lamp. Braclet for cell phone
What to do when You want to look on Your cell phone, but You have no hand available to hold the cell phone? Because You are running or driving an electric scooter? Airport Moscow transit area
Search for a power outlet, behind the chest is one. WLAN internet is free in Moscow airport. Munich airport can learn from this!
