    Custom flip down 12.1" VGA/HDMI/DVI touch screen monitor

    This does not involve as much fabrication as some of you guys have done but I decided to get a second monitor in my truck that could handle the input from the computer and have touchscreen capabilities.
    I searched high and wide but could not find a monitor that offered HDMI, DVI or VGA and included a touchscreen.
    The closest I could get was VGA only and no touchscreen so I decided to build my own.

    Parts:

    Lilliput 12.1" Open Frame Monitor with HDMI/DVI/VGA and RCA inputs
    Compatible Flip Down monitor that is reasonably priced that I could rip apart and use as a donor shell to put in my parts.
    Custom LED lights for better lighting.

    Goal:

    The goal here is to get it as close as possible to the look of the original unit I will purchase but be able to use at least one or 2 of the computer inputs for my CarPC as well as retain the touchscreen capabilities

    For starters I picked up a cheap TView flip down (roof mount) monitor from eBay for a few bucks
    I did my research and even though TView claims this was a 13" monitor the actual viewing area was actually supposed to be 12.1 inches (even that was slightly off I later learned).

    I got the monitor in the mail and within 30 minutes I had already taken it apart to see if I can make it work.
    All of this was without ever turning the brand new unit on to even find out if it worked.




    Display with old LCD in place (take note of the metal mounting bracket. This would be my first obstacle as I will somehow have to get all the wires from the screen passing through the bracket for this to work)

    First thing first, I concentrated my efforts in the LCD display
    I took the LCD out and test fitted to be sure my LCD would fit.
    I must say I breathed a slight sigh of relief when I realized that the Lillilput LED back-lit LCD was close to 8mm thinner than the one that the monitor originally came with which meant I would have a bit more room to work with.

    After a lot of thought and self debate whether to cut all the wires and re-solder them after passing them through I decided after studying the bracket that I could also go another route.
    I decided that since the bracket was made op of multiple pieces I could use my dremel and cut into each piece to get the wires in and while reassembling ensure that all the cuts do not line up so that the wires are still technically lock withing the assembled bracket.

    Here work took precedence over picture taking so I only managed to get a finished picture.



    Unfortunately I had to loose the VGA cable as due to the size of the HDMI one I could not get both to fit. I also tried using an HDMI extension which was thinner however Lilliput built their HDMI cable to include the wiring for the touchscreen so I could not get the touchscreen to work using the extension



    LCD and board assembled I also put the button and infrared board behind the translucent panel to the right of the image.
    This was I retain the functions of the remote since I could not manually rewire the buttons to location of the original without extensive work.

    I also wanted to retain the dome lights so I looked at the unit to figure out how the existing light work so I could rewire it into my application.
    Unfortunately it turns tout that the original lights were there for show only as I could not see any button on the unit to turn the lights off or on or any wiring for that matter to the domelight wires of the truck
    This meant that I would have to build my own circuit for this part.



    The original led in the unit (pictured above) did not cut it for me so I figured I'g get my own and wire it up.



    It is a bit pricey for a LED but I was working on the project and did not want to stop for a couple of days while waiting for LEDs to come in the mail.
    So I hit up my local Autozone and picked 2 of these up for my build.

    I also needed to build custom switches if I wanted to be able to turn the lights off and on as well as have them work with my doors.
    After figuring out that my dome-lights were negatively switched from the doors I went ahead and drew my circuit on a sheet of paper and started building.




    The black spring loaded piece on the side is the switch to allow anyone to turn the individual LED on or off. Two switches one on each side and separated by diodes to prevent current flow from one side to the other quickly fixed my problem.

    After a lot of hard work , I give you the finished product.



    VGA Input


    DVI Input


    RCA input


    HDMI




    I did notice that the edges of my screen are a bit cut off because the old screen was even a bit smaller than 12.1 however I figure I can create a custom resolution to accommodate it as I see fit.
    Now to get this thing in the truck and test the lights to see how well it all works

    Wow. That's some really nice looking work! I didn't even know you could do that vinyl wrap thing. I have held off on making a custom dash panel because I didn't want to just paint it. I may have to Google that, thanks for giving this newbie a new idea.
