    12V Flip-down VGA monitor and CPU

    I have purchased a Shuttle X-mini as a CPU to run my navigation software (Navionics) on a 45' sailboat. We are headed across the Atlantic next month! Anyhow, I have 2 issues.

    1) Where do I get a 12v-12v voltage regulator? Basically, my batteries are anywhere from 12-13.4V but my computer can only accept 12V. It isn't too tolerant on variations in voltage.

    2) I am looking for one (or two) 12V monitors so I don't have to deal with the inverter. I would like them to be flip-down as space is an issue. I am looking in the 10-12" range. 19" is way too big.

    BTW, will my computer have any issues running a 12V monitor? I mean, wouldn't it naturally expect a 110V monitor? Maybe the CPUs signal is voltage-independent, I dunno.

    Any other tips on configuring this system openly and greatly appreciated! Thanks!

    Are you looking for a touchscreen monitor?

    Check out the p2140 or p1900

    You would need to make a cable connecting this to the shuttle, but theoretically, this shouldn't' be too hard.

    Touch or no touch?
    If you are on a budget, you could mount these from the ceiling and they would fold relatively flat.
    $312.99 http://store.mp3car.com/Lilliput_10_..._p/mon-027.htm
    $189.00 http://store.mp3car.com/Lilliput_FA1..._p/mon-051.htm

    expensive options would be $550-$630

    To have the cleanest signal on your monitor and have a long monitor life, you might want to consider using the secondary regulated 12v output on the supply to power your 12v monitor. This will filter out any alternator or motor noise from your boat.

    There are no issues running a 12v monitor with a computer as long as it is powered well.

    Posting a picture of the installation area would allow us to give you some more tips.

    This is also a nifty little accessory you might want to check out:

    This USB port mounts nicely in wood or fiberglass.

    There are a bunch of cables already made for other types of computers which might work on the shuttle. Check out the cable lists here:

    Do my eyes deceive me?

    Good to see you here Fiberoptic.

    Thanks, all, for the input. Good stuff.

    I do not require touch screen. I have a wireless mouse that I plan to use. The monitor at the nav station (I hope the pics uploaded OK) would be on the ceiling on the left side of the picture, just above the nav station. We are crowded on space. Anyone carry these? I can get them all day long...if I want to take my chances sending money to China!! I'd like to find one here.

    The P2140 DC regulator looks good. But it only has 2 outputs. I was thinking of running 2 monitors -- one at the nav station and one at the steering station. That would require 3 outputs. Or do monitors really need a regulator? Or can one of the monitors be powered through the Shuttle?

    What did you think of the Lilliput 10" displays? They would probably collapse and only use about 2" above the nav station. if your shuttle uses 12v, you could power the shuttle and 3+monitors out of the primary output just by using a very basic 12v distribution block.

    You should regulate your monitors if at all possible.

    The Lilliput 10.4" flip-down model would do just fine...if I could find one. When I google it, I come up empty.

    I think I understood what you said about the distribution block. It sounds like I can get a DC dist. block, and plug that into the monitor output of the Shuttle?

    Here is the monitor link.

    For power distribution here is the way it works.

    Regulated 12v from carnetix ---->distributed to--->Monitors, shuttle.

    A bad install would even just use basic wire nuts. you could solder or use a distribution block, or other types of marine grade crimp connectors to do the distribution of the regulated 12v power output.

    Thanks, Fiberoptic, but the monitor link did not upload. Can you try again?
