Success ** greenuns' build log

[greenuns]

hey guys,
thanks to all you great adventurers out there
and Drew! Yay!
, i've finally managed to start a build.
I got a 12x12 artzII wacom pad and
a dell 1503fp screen.

Since the 1503fp is a popular screen here, i'll just skip the dell disassemble.
It was actually quite straight forward. I just followed Drew's guide and everything came apart just fine.

Sorry about the photos, I know they are bad.

anyways,
here's the stripped screen.
Because of the two ffc and it's samsung panel I was hoping this panel is the same as Drew's.



I don't even know what these are called, here are some "other parts"
The ffc extensions are 40pin + 0.5 pitch





Looks like the panel was assembled by "Min-Kyoung Jung" from Section C 
I had the exact problem as Drew. The damn screws won't unscrew.
So I also got a dremel and grinded the screws and then used a flat screw driver to take them out.
Now I know it's the same screen as Drew's, hehe




After unscrewing everything and a bit of pushing and pulling, everything came apart.



That's a big slab of plastic in there. Does anyone know what this is called?



Ok, slapped the LCD on top and everythings working. Although there's some drop outs every now and then.



I'm guessing it's the gap from the plastic frame.



Before the Dell 1503fp I tried a Westinghouse 15" monitor which had these wierd tubes in it.
I tried to make it work with this monitor but had jitters, drop outs you name it.



but I managed to salvage the "plastic slab" from the Westinghouse which filled the gap perfectly after I dremeled off a few cm at the bottom.



then I taped the whole thing together with electric tape. (Damn, i forgot to take a photo of that...)
and placed it on top of the tablet.

All worked, hardly any drop outs and no jitters.

Setting up the tablet was a real pain. The pointer is kinda underneath the pen but it's a little off. But aligns perfectly when it's in the middle of the screen. I had to settle with "map monitor 1" function because I couldn't understand the "Advanced Mapping" thing. But it's annoying because my MBP native resolution is 1440x900 but I have to set it to 1024x768 for the "cintiq" to work. Anyone have a tutorial on mapping the tablet?

I placed a 8.5x11 acrylic board on top of the LCD for protection but there were a lot of pressure problems. I couldn't get the pressure variation I wanted. But then I tried a piece of glass from a frame (2mm thick) et voila!!

Here's a video of the tablet in action.

I'm gonna get a piece of glass that can fit the screen and goes over the white plastic frame.
and then try to put it all back inside the wacom casing. Man that's gonna be a task.
Any cool ideas would be great.

  nice another success

this is how i synced the tablet to the screen

Set up ur screen at the resolution refresh rate you want
Then start up wacswitch - this loads up the wacom tablet properties window.
Select the mapping tab

and then click where it says Tablet Area:
Set it to portion


Then this window appears, select option 2: Select Area with tool (Button Labeled Click to define Tablet Area)
Click on the four corners of the screen, that should do the major work for you.
Then I used the monitors adjust Vertical and Horizontal screen settings to move the screen around a pixel at a time till the mouse pointer was perfectly underneath the pen

Thats my method anyhow

 

[Switz]

Nice

Yeah, do the click to define area.

[greenuns]

sweet, thanks
I'm gonna try that when I get home.
did you guys configured the tablet before putting it all back together or after?
I'm guessing after?

[dynam1c]

yep after would seem to make more sense as thats when its in the dont touch it now its working state.

[Drewid]

Need to do it after.   You can also adjust the area of the tablet by typing in numbers which is obviously more accurate.

If you go to the helpmenu in the wacom drivers there is a diagnostics option.
This gives the current pen position in "counts"  so holding the pen against each edge of the screen should give you the minimum and maximum "counts" for x and y.

The numbers bounce around a bit so you need to get a good rough guess then adjust it a bit afterwards.

[greenuns]

thanks guys.
When putting everything together, how did you guys fix the LCD to the wacom?
did you guys tape it down? glue? or did the cutout of the wacom case (the hole on the wacom case where the lcd screen shows) hold it?

[Drewid]

I had the backlight taped to the Wacom sensor and the LCD taped to the lid.  The hole in the lid was just slightly smaler than the screen.

First I put the lid on (no screen) to get eh backlight lined up, then taped it in place.
Then I put the lid on the backlight upside down, with the screen on displaying a white desktop to get the LCD edges lined up with the hole,  then taped that down.

[DonShole]

I taped everything including the glass screen protector to the tablet, using double sided adhesive tape to hold the backlight housing in place initially.

blue eletrcial tape held together with the sweat and tears of a 1000 virgins chanting the maha mantras of the echok nai.

[greenuns]

cool, i better get some blue electric tape, i wonder if it comes with 1000 virgins
i'm gonna try and put it all together today, fingers crossed!

[Drewid]

not form Maplins it doesn't
Perhaps RS is still running it's 1000 virgins spring sale?

[greenuns]

Hey guys,
My build's been on hold forever, but now that I finished a major project I can go back to finishing my build. yay!
do I need special cables to extend this cable? it's the cable that connects the CCFL board to the main board...

or what wires did you guys use?

[Switz]

You should NOT extend that cable.


That will make your backlights dimmer.

Extend the cable to your main board FROM the lcd

[Chems]

Ignore him hes gone insane.

Hes telling you to do what your already doing.

I did it on my monitor and I just used some standard sort of wire I picked up from maplins. Not had any trouble so far.
