News around notebook laptop computer

Always actual informed. Last news about notebook and laptop computers. Digital cameras as permanent companion and photographic memory.

Notebook outdoor all the day
	Complete system for the solar power supply of notebooks and longer run time by an external battery.

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.

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.

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 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.

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.

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.

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?

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.

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.

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.

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

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.

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.

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.

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.

Photovoltaic for the mobile usage
	34 Watt peak, foldable as a 2 kg package to pack in every backpack. In the case of working on the beach, in the mountains or on an expedition the ideal power supply.

12V power supply
	At the 12V plug from the battery is a 3 plug connector for the AA battery charger of my Canon-S1, charger for the cellphone and car adapter for the notebook.

Light buffer battery for solar power
	Changing to an 1,8 kg notebook, the buffer byttery for the solar equipment should weight less than 2,5 kg. For the small consumption of the ASUS UL30 10 NiMh batteries.

Screen in sun
	Antiglare is a have to at purchasing a notebook. Otherwise, the display would be like a mirror like the incasement around the display. With 2 eyes, the screen content is more easy to recognize.

Foldable photovoltaic module
	Such unapparent small, I take the folded 34 Watt module out of the backpack. With 2 kg weight, it produces with 2 hours sunshine the same amount of energy

Multi power supply for netbook is enough for ASUS UL30
	All in one, 12V DC car adapter, airplane adapter, 100..240V AC with 40 Watt and an USB charging socket for my Android cell phone

Light tripods for digital cameras
	The best tripod does not help, when it was not taken along when it's required. Test of tripods in the lowest weight class up to 1,2 kg.

Airbus 320 seat
	The provision of space in the tourist class is in harmony with the size of my ASUS UL30 notebook. What to do here with my old Lenovo thinkpad R61?

Office at the waterfall
	To work has nothing to do with being cruel to yourself in a stuffy office. GPRS, UMTS and a solar power supply makes it possible to work in an inspiring environment.

What delivers a photovoltaic at sun behind clouds?
	Behind a sparse cloud is the sun recognizably. My foot throws already the clue of a shadow. 0,8A charge current. 30% of the 34 Watt peak.

Sealed lead acid battery with charge regulator
	The charge regulator is simple with double sided adhesive tape glued on the sealed lead acid battery. Also this should be only a temporary stopgap.

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?

Panorama software test
	The big quality difference between PhotoStitsch 3.1 (delivered with the S1) and our since 2000 used PixAround induced a big compare test.

Swim break
	As soon as I go swimming, my doughters jump to the ASUS UL30. Both would like, that I swim for hours, otherwise they want to go home.
