    I've been asked a few times about the 12v PC I built for my motorhome and I've finally gotten around to making a video on it for anyone that's interested:

    :thumb::thumb::thumb::thumb:

    The best post i have seen in years :Eeek:

    But... yes, there always is a but. English is not my native language so can you please add the specifications and attributes in writing.

    I want to be sure i am using the right components :Doh:

    Thanks in advance :thumb:

    Excellent video...

    I really like your setup. Just a shame your requirements are a bit too low for me to do the same.

    I am however interested if you have a link for the adjustable voltage regulator. That will be handy for a variety of uses in my van :thumb:

    I am impressed with the low power usage. My big laptop which is based on a core duo uses anything up to 6amps when going full tilt so your system is more powerful and uses less power than my laptop. Which just goes to show an old laptop is not necessarily the best thing to use when on the road :Doh:

    If your monitor is capable of 1080p any chance of a link to it please?

    Hi Onderweg and thanks for your comments :Smile:
    I'll list of all the components and links to them later today once I get a little spare time.

    Hi Gromett and cheers :Smile:
    The voltage booster/regulator I bought from Ebay here:
    http://www.ebay.co.uk/itm/300933289543?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649
    I was a little sceptical that it would do the job as it was only a few pounds but tested it thoroughly before installing and it's a great bit of kit. I've had it running off a flat battery (about 12v off the terminals) and with a CTEK charger on recon mode so the terminals are pushing out 14.5v and the voltage out of the regulator didn't fluctuate at all.

    The monitor is a LG 24EN43VS, here is a link to it:
    http://www.lg.com/uk/monitors/lg-24EN43VS
    It is 1080p and has really good viewing angles compared to other TN panels I've had - comparable to the IPS panels I use on my main rig. It's also very thin and light. I think I paid about £110 for it.

    Great thread.
    Note to anyone buying a regulator. The output cannot be lower than the input voltage, so cannot be used to regulate voltage to 12v for TVs etc.

    Great little box.

    But why not a laptop ? So much easier to store away from prying eyes when you leave the MH and for travelling.

    Hi Hilldweller,

    I did initially think about using a laptop but in the end decided on a full PC for a few reasons, the main one being that I don't like working from a laptop :Smile:
    I just can't get used to using a small screen and working so close to it, I prefer to sit back with a wireless keyboard.

    The other reason was, as the PC is also the TV in my van, it's nicer to watch it up on the wall as is the norm.

    Another pet hate of mine is wires. If I used a laptop I would have to trail the power wire across the van and maybe wires to connect to Wi-Fi (unless I used a wireless router). Wires are a little impractical for me as well with a dog that likes to ambush me at random times :Doh:

    I did consider security. The PC will be locked away when I'm in the van (well vented space) and removed when I'm away from the van. It's smaller than a laptop so easy to remove. In fact as it's so small it can be put in my on-board safe if needed.

    Thanks for your comments,

    David

    Thanks for your reply, good to read your logic. In fact, on second thoughts, your PC is inherently safer than a laptop, it's not so saleable, they might not even guess what it is.

    Anyone without your skills might consider one of this type with a 12V power supply as used for laptops.

    AAMOI my hauphauge TV dongle was giving trouble and I took a punt at a £5 ebay one. Smaller than a USB memory stick. I works a treat though the software is only B league.

    Sorry it's taken me a while to get back to you - just been busy :Smile:

    Here is the complete spec:

    Power Usage:

    The entire system (including the monitor and all of the wireless devices) runs on about 40w per hour. If I’m watching TV and using the sound bar this can rise to around 50w per hour.
    As far as how this impacts on the leisure batteries the system uses about 3.2a per hour, rising to around 4a with the TV and sound bar on. So if I say have the PC on for 8 hours then watch TV for a further 2 hours the system will draw around 34 amps per day.
    This is less power than my laptop uses. It’s also much faster than my laptop and has a 24″ screen which is a bit of a luxury in a motorhome [​IMG]
