I've thought about Android, but I am concerned that the Android 'universe' of apps and online info is alot smaller than Linux. What Android apps would you use for navigating?

ASUS - Eee- ASUS EeeBox PC EB1007

Newegg.com - lenovo ThinkVision LT1421 (1452DS6) Black 14" 8ms Widescreen LED-Backlit LCD Flat Panel Monitor 200 cd/m2 400:1 The display burns 5W or less, and with keyboard and mouse plugged in, and the EeeBox powered with a 12V/18V adaptor, the whole mess draws under 2A @ 12V. When I plug a quad RS232/USB adaptor, and an Iridium satphone into the remaining USB ports the current drain is under 2.5A @ 12V.
Hint: To use only the USB monitor, you need to have a “dummy VGA plug” plugged into the EeeBox VGA connector. Otherwise the EeeBox never completes the startup sequence and the USB display remains blank. I spent a few hours figuring this out!
This particular USB monitor has LED backlights, and there is a button on the back that lets you adjust the screen brightness. The lowest setting is completely appropriate for use on a dark night. I haven’t tried the display in sunlight, but that’s not where I will be using it. I’m looking for a software method to control the backlight, but haven’t found one yet. The brightness button is pretty easy to reach. This monitor and computer are both light enough that you could secure them with velcro if you wanted.
The EeeBox runs Windows 7 (64-bit), and so far all the programs I need are working fine.


Above was posted by Valis June 2012 on own website.

Sounds neat but how much$$? I didnt see a ,link to buy the eepc and the link to the newegg page for the monitor says NLA?

Re: 12vdc Marine Computers

From YachtValhala's website:

March 2010
"On a recent trip to Singapore I found an ASUS 1000 netbook with Linux operating system and 40GB SSD (solid state drive). I installed Windows XP and all of my navigation programs. The power consumption of this machine is a miserly 800mA while simultaneously running five navigation programs. Now THAT's more like it!"

He previously used a 12v
ASUS EeePC 1000H that drew about 1.13a or 13.5watts and liked it. His page here: Cruiser

Re: 12vdc Marine Computers

I have purchased a second monitor to use in the cockpit.

1.I would like to turn the inside monitor off to conserve power. Does anyone know how to do this in XP??

2. Do to the screen size of the second monitor the depths are rather small for vector charts. Does anyone know how to increase the font size for vector/cm93 charts?

Re: 12vdc Marine Computers

You can go into the control panel power options and set a low time for the OS to turn off the monitor or better you can just hit the power button on the monitor. Anything else would involve the control functions of your graphics section.

If there is a way to make the font size larger for vector charts then someone else will have to chime in.

Lake-Effect,

See my 'how to' here: Building on Motorola Xoom | Official OpenCPN Homepage , and thread here: OpenCpn Install on Android Tablets Easier Now.

There has been a report from sevanopula that he has successfully used a bluetooth gps with OpenCPN running in a chroot, linux environment on his android tablet. Solutions for using a usb gps are being pursued, and rather involved methods have been proposed. We are hoping mrm, marius - a poster in the thread brings a simple fix forward relatively soon.

Personally, I have no need for a gps connected to OpenCPN. Read my posts to find out why.

There are also Windows tablet users presently trying to get a gps - built in or usb - to work.

Thanks for the reply.

Unfortunately the timeout idea blanks both screens and the inside computer is a laptop, so no power button. So far the best I can do is dim the inside screen.

All the laptops I have had have a key on the main keyboard that allows switching from the laptop screen to an external monitor. Is that your setup, the screen on the laptop below with an external monitor connected to the VGA output on the laptop? In that case easy to switch from one to the other just using the keyboard.

Then if you are having problems with the screen in the cockpit blanking out go to the setup screen on your laptop and disable the power saving feature that blanks out the monitor. Then it will stay on until you turn off the computer.

Most laptops that offer an external video output allow you to choose which screen to use from the keyboard. If you have an Intel based system you can choose which screen to use from the Intel graphics window.

Re: 12vdc Marine Computers

I was searching for a 12V monitorwith VESA mount 2 years ago and the only one I could find at the time was made by Planar. I have the model PL1900 19". I had hoped to wire it directly to the M4-ATX power supply in the computer I put together so the 12 volt power would be regulated. For reasons I still don't clearly understand, this caused horizontal lines to scroll on the monitor. Planar makes a 12V power brick that stabalizes the voltage. I ended up going that route. Would love to find a better solution.

Re: 12vdc Marine Computers

I'm not sure why your M4-Atx caused lines on the display but it probably wasn't necessary to use regulated 12 volts. I've ran a Planar PE1700 directly off my 12 volt batteries for years and still use it in my office. I replaced it with a Mag Innovision GML 2226 with LED backlighting (no longer available).

Currently available is the Hanns-G HL203DPB with Vesa mounts and Samsung has The S19A450 and S19A200 series available with LED back light and Vesa mounts. These will all run directly off of your boats 12 volt buss.
