    looks like you are going to need to make a seperate power supply for this screen.

    i think a couple maxim chips and their associated circuits should be able to put out the power that you need for this thing.

    a max787 will give you regulated 5V at up to 5A

    a max1771 will give you regulated 12V at up to 2A

    both the datasheets from www.maximic.com will give you a typical circuit design, that should be enough to slap something together to put out the power requirments of the screen in a 12V environment.

    the 100% margin on the current capabilites should cover any spikes you might see...

    wait a minute.... are there 2 power supplies for this screen????
    now im confused. i believe there is only one power jack on the casing, so only one voltage should be required for the screen to run.
    anyway, those maxim chips should be enough to get started on the supply, if you need more current on the 12v for some reason, then put an identical 12v circuit in parallel and have a common input, output, and ground. that will double the available current on the output.

    Would these lcd's work on the normal european electrical net?
    Thats 220/240 volts instead of 110 in the us

    They run on DC, it seems, so you'd just have to get a different adapter for it.

    the screen has a viewable area of 10.3 inches... i dont know if the other .1 inch is under the casing, but i think the 10.4 touchscreen should work.

    from the picture on the website for model number res-10.4-pl4 it appears that all the components are included. so i think all you would need is some foam mounting tape for trouchscreen installation... i didnt see that in the kit.

    £91 isnt a bad price for the entire setup... i might look and see if i can get a controller for my spare 10.4 with touch overlay... hmmmm

    looking again, the 8-wire is the same price as the 4-wire and i think the 8-wire gives you better "resolution" for the trouch screen. i also think you can do "click-and-drag" with the 8 and not the 4, but i might be confusing that with the controller abilities...sorry if im confusing you, im kinda just rambling now!!!

    Would someone buy me something?

    I know i am a newbie here but i'd like to ask a big favor to one of you guys.

    The guy selling this, http://cgi.ebay.com/ws/eBayISAPI.dll...tem=2024277024 won't ship internationaly so i was thinking if someone would buy one and the ship it to me.
    Of course i would pay for all expenses and i'd add an extra for your trouble.

    Would someone buy this for me for like 90USD with all included (guy shipping to you and then you shipping to me)?

    The problem is that i only can send you the money throught Western Union, since PayPal doesn't accept my card.

    If someone is interested please email me, i know there isn't much time to the end of the auction but i'd like to give it a shot.

    Thanks a lot and please excuse my english

    Seems like we have to wait for these

    I mailed the guy yesterday and here's his reply:


    I have been completely overwhelmed at the interest and demand that I
    have received from these LCDs. Please understand that I am trying to
    organize the orders I have before me. I have decided to give those
    early in PMing me, posting interest in the thread and emailing me
    priority. I am sure I can get another shipment so I will be able to
    provide for the rest of you. Those of you that I have chosen to go
    ahead with the first shipment will hear from me tomorrow regarding
    payment and shipping. The rest of you will hear from me real soon. I
    am sorry for my lack of organization; I did not know there would be this
    much demand. I hope to be able to provide each and every person
    interested at least one LCD. Thank you for your patience.

    Best Regards,

    Vince




    So I think we all need to be patient...
