Thread: Lilliput screen inside motorized unit?

It would be good if we could develop an 'open-source' motorised VGA in-dash housing forged from one of these cheapo composite-only units married with a Xenarc/Lilliput.

I share the opinion that getting the motors going again using a microcontroller would be achievable after stripping the original guts out of the housing. I don't think we should get too hung-up on this problem being a deal-breaker.

The only remaining big question for me would be as to whether it's possible to fit Lilliput/Xenarc controller boards into the chosen motorised housing.

I'm in the UK and have noticed a few of these suspiciously low-priced in-dash motorised LCDs on ebay...

ebay link 1

ebay link 2

ebay link 3

All three of these look cosmetically different from the 7" motorised unit sold by mp3playerstore. It'd be interesting to see how many motorised in-dash variants are floating around at the moment.

I certainly want this problem solving enough to put my money where my mouth is and get one of these things to experiment with.

I have actually been toying with this idea as well, and right now i'm in the process of searching for the indash lcd/radio that I can tear apart to start looking for an LCD controller card combo to fit into it, figure if I can find one with a cracked lcd would be the best bet, should go cheap. I figure if I can get at least VGA then move up to touchscreen later I would be happy. But I think the motors would be easy to control for opening and closing with a pic microcontroller.

I'd like to have my Lilliput in one of these too. Can anyone post pics and measurements of the inside of the LCD housing ? Better still, do a test fit of the Lilliput touch panel, LCD screen and controller to see if it fits.

how complicated could are those motorized open/close controllers...

i'd assume its not just open at low V close at high V..... since you also have to deal with when to stop trying to open/close

Motorized Xenarcs are sold, a slimline dvd player can be put underneath it, and you have pretty much the same thing. Why destroy $2000 worth of equipment?

Where is the motorized Xenarc available from? I did not think this was out yet... Stop me before I spend the 400 on the Xenarc screen to mount it in my 701 housing!

The logic is relatively simple:
- determine the position (open/closed...) of mechanism using the sensors (microswitches, optical, whatever),
- power right motor to open/close/tilt
- cut off power when the sensors indicate the desired position has been reached.

Relatively simple to implement in a PIC.

Does that mean we should still hope for a motorized touch vga? I read in another thread where they realised that there is no market for these. Has anyone come across a tutorial for converting a touch vga to an indash motorized unit, and where the products are atually avaiable to buy?

might solve some of your problems...

Oh yeah, that aussie was asking about a how-to install lilliput to indash unit... Here you go-

It's... uhm... pretty detailed.
