    Thats right.... the controller for the LCD and the motor controlling circuit are integrated on the same PCB.

    Well if Autonode gives us another delay I propose to all who have electronics experience to sit down and design a stepper motor controller

    Here is what you can do. leave the original pcb and everything connected, and take out the screen itself. that way the motors and buttons keep working like normal. the lcd controller wont care if there is no screen connected, it should still eject the screen enclosure normaly.

    Now the part i am not clear on:
    Spec-V- you said that there was plenty room for another pcb. is that still ture if you leave the old pcb in?

    if not then there is still a solution. just remove the old pcb and extend all of the wires and install it somewhere outside the unit.(so i can keep doing its work). and install the lilliput controller inside the unit.

    As for the buttons, i would leave them alone and just extend the ir sensor and install it somewhere on your dash.

    In theory the original controller should continue to open and close the screen.

    Good luck bro, i hope someone out there has the balls to try this out.
    I will try this soon.

    Thats a good idea Darkhalo. But that would mean we wouldnt be able to use the buttons on the motorized unit to control the lilli. I guess we could use the infrared, but having the buttons sitting there and doing nothing is a bit of a waste. Also having a LCD controller sitting there ONLY to open the screen is a waste of a perfectly good LCD! I guess with a lot of hard work it would be possible to extend the wires from the non-lilli controller so that you could plug only the screen in somewhere else in the car, but doing that would mean the extended wires would get EMI and make the image look all crappy.

    hmmm its a gamble. I will see how it goes though. I really want to do something like this.

    I'm new here and haven't done my carputer yet, I was just kindof searching for ideas when I stumbled on your post. I'm guessing the only reason you wanna do this is to keep the TS of the Lilliput, right? Why not buy the unit that someone suggested above, then install a TS film kit to that monitor? It seems a hell of alot easier. You can buy them at this link for like $100 and they have DIY instructions on the sitehttp://www.digitalww.com

    He wants to use the lilliput for the VGA input. Not just the TS.

    And with the screen you are looking at (The one I have) you wont be able to do what the last guy said. The controller for the LCD has a ribbon cable that connects to the screen assumably for input right? Well yes that is part-right. The controlls for the motors/gears/microswitches are integrated into both the LCD controller, VIA the ribbon cable that connects to the LCD... and to boot, the buttons to open/close and adjust the angle of the screen, are all soldered and integrated with the screen's housing.


    So, unless you can completely design a control circuit that can use new microswitches that opens and closes the screen, you are not going to get this to work.


    Believe me, It is no small task.

    Yeh, what the other fellas said. I would prefer to keep my VGA input LCD screen. The other ones (svideo or RCA input) arent as good in quality and make it hard to read small fonts.

    It has sufficient room inside for a new controller... but getting the motorized function to work without the original controller in there is nearly impossible.

    Someone more skilled with PCBs like Armin might be able to do something with it.

    On the other hand... the screen's quality and brightness is awesome. I have been using it for my Sentraputer for several months.
    Can you post pics on the guts of this thing ? The mechanism should have 1 or 2 DC motors for traverse/flip plus some optical sensors for position sensing. It shouldn't be too hard to build a new controller using a PIC and some motor driver ICs.

    When I had it apart... I sanded it down and repainted it with black metallic automotive paint... its in my dash now so... no pics of the guts.

    It had 2 motors and no optical sensors.. only microswitches that opened or closed when the unit was in a particular position.
