Title: Success ** greenuns' build log
Post by: greenuns on April 03, 2007, 08:03:20 AM
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  ;D
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.
(http://img151.imageshack.us/img151/753/img2896ob8.jpg) (http://imageshack.us)


That's a big slab of plastic in there. Does anyone know what this is called?
(http://img201.imageshack.us/img201/4207/img2898nz2.jpg) (http://imageshack.us)


Ok, slapped the LCD on top and everythings working. Although there's some drop outs every now and then.
(http://img223.imageshack.us/img223/4173/img2901dz9.jpg) (http://imageshack.us)


I'm guessing it's the gap from the plastic frame.
(http://img460.imageshack.us/img460/8757/img2904tn4.jpg) (http://imageshack.us)


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.
(http://img341.imageshack.us/img341/1167/img2910ok5.jpg) (http://imageshack.us)


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.
(http://img151.imageshack.us/img151/5002/img2905st9.jpg) (http://imageshack.us)


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.
http://www.youtube.com/watch?v=pS0uIuwZOs8

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. :)

 ;D 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
(http://img258.imageshack.us/img258/6903/untitled1rk7.jpg)
and then click where it says Tablet Area:
Set it to portion

(http://img490.imageshack.us/img490/671/untitled2fa5.jpg)
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

Nice :)

Yeah, do the click to define area.


Title: Re: greenuns' build log
Post by: greenuns on April 03, 2007, 07:01:44 PM
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?


Title: Re: greenuns' build log
Post by: dynam1c on April 03, 2007, 07:27:01 PM
yep after would seem to make more sense as thats when its in the dont touch it now its working state.


Title: Re: greenuns' build log
Post by: Drewid on April 04, 2007, 01:35:42 PM
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.


Title: Re: greenuns' build log
Post by: greenuns on April 05, 2007, 06:02:12 PM
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?


Title: Re: greenuns' build log
Post by: Drewid on April 05, 2007, 06:30:17 PM
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.


Title: Re: greenuns' build log
Post by: DonShole on April 05, 2007, 06:34:17 PM
I taped everything including the glass screen protector to the tablet, using double sided adhesive tape to hold the backlight housing in place initially.

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!

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

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...
http://img413.imageshack.us/img413/8145/cablekh6.jpg

or what wires did you guys use?


Title: Re: greenuns' build log
Post by: Switz on April 29, 2007, 11:22:32 PM
You should NOT extend that cable.


That will make your backlights dimmer.

Extend the cable to your main board FROM the lcd


Title: Re: greenuns' build log
Post by: Chems on April 29, 2007, 11:23:54 PM
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.


Title: Re: greenuns' build log
Post by: greenuns on April 29, 2007, 11:54:10 PM
so any wire will do?
is there a specific gauge? ohms? volts?
do I have to solder the wires? or is it just a twist and turn with tape job?
sorry, i just have no clue with these things....


Title: Re: greenuns' build log
Post by: Switz on April 30, 2007, 02:24:36 AM
I beg to differ chem (NO S lol)

You are the one that is going insane, he said from main board to INVERTER,

you are not supposed to do that


Title: Re: greenuns' build log
Post by: greenuns on April 30, 2007, 04:21:28 AM
sorry lads, i should've been more specific. that cable connects

this

to this
(http://img259.imageshack.us/img259/2706/2904072319kd1.jpg) (http://imageshack.us)



or should extend this cable?

Title: Re: greenuns' build log
Post by: Chems on April 30, 2007, 11:43:43 AM
Yeah Ive just read your other reply. Make sense what your saying, about small power across that little cable.

I extended my Main Board to Inverter Cable and it worked fine.


Im not sure anymore now, best listen to switz as you guys have the same monitor.


Title: Re: greenuns' build log
Post by: greenuns on April 30, 2007, 08:57:11 PM
so should I extend the CCFL wires?
and is the top most image the inverter?


Title: Re: greenuns' build log
Post by: Switz on April 30, 2007, 11:12:09 PM
I would say extend the ccfl wires because that seems to have worked twice now


Title: Re: greenuns' build log
Post by: Chems on May 01, 2007, 11:00:23 AM
If this works I may extend my CCFC wires as it will make the back of my build tidier.


Title: Re: greenuns' build log
Post by: Drewid on May 01, 2007, 01:11:52 PM
The "it doesn't work" thing is something I heard second hand,  and seems to be incorrect.


Title: Re: greenuns' build log
Post by: greenuns on May 01, 2007, 08:12:06 PM
ok, i'll try it out.
the way my build is that I would need to extend that cable so that it becomes at least 8 to 10 inches..
I hope that doesn't kill the screen...
then back to the type of wire question,
Any wire will do? and is it a twist and turn job? no soldering?


Title: Re: greenuns' build log
Post by: Drewid on May 01, 2007, 09:51:46 PM
For the ccfl wire I would recommend at least use a connection block (terminal block) like bubbaflamm used for his LED strip.  being as it's high voltage I'd be very wary of relying on a twist n tape job.


Title: Re: greenuns' build log
Post by: bubbaflamm on May 01, 2007, 10:17:07 PM
the terminal block can be easily cut down to the number of terminals you want, too.  so if you only needed 2, you wouldn't need to make room for a whole block of 12.
I can't tell from the pics (slightly blurry pics combined with even more blurry eyes.  I've needed to visit the eye doctor for too long), and i'm not sure which wire it was decided was teh one to extend,  but i have successfully transplaneted in new wires on many occasions.  you may be able to simply remove the wires that are there and put in longer un-spliced ones.  if it can be done, that would probably be the best solution.


Title: Re: greenuns' build log
Post by: Chems on May 01, 2007, 10:58:19 PM
I will wait for you to take the point on this one greenus. If it goes ok I will be replacing my extended Main Board to inverter wire for 2 extended CCFC wires.

Post by: greenuns on May 02, 2007, 08:35:05 PM
hey guys,
thanks for all the great help.
I have one deadline to make, which is due tomorrow and after that I'm gonna go cintiq!
Drew, the terminal blocks look great, I didn't even know they existed...thanks, I'll be getting those..
I typed the serial number on the wire in google and I think these are the actual wires.
http://cn.100y.com.tw/PNoInfo/14542.htm

but seems like it's in taiwan..I'm gonna see if any of my chinese friends can translate this
but if anyone speaks mandarin could you check to see if there's any spec?
thanks


Title: Re: greenuns' build log
Post by: bubbaflamm on May 02, 2007, 08:54:35 PM
 try this.  i think it's the english translation

Title: Re: greenuns' build log
Post by: Chems on May 02, 2007, 09:40:35 PM
That is the main problem, what sort of wire to use. I suggest just a bit of high voltage normal wire.


Title: Re: greenuns' build log
Post by: greenuns on May 04, 2007, 02:40:07 AM
guys, it works!!!!!!
I had a Westinghouse LCD lying around (which I thought I threw away), the LCD with 3 tubes and stuff, so,
I cut up the CCFL wires from the broken LCD (luckily the wires were the same, with the same serial numbers), got some terminal blocks, same ones as bubbaflamm
and put them all together, black taped everything and it totally works!!
I'm typing this from my taped up cintiq.I don't know how dodgy the connection is so I black taped pretty much anything that is metal.
hopefully I'll be able to borrow a camera tomorrow so I could show you my dodgy wiring...

so by using the same wires, it's a success. Length doesn't seem to be a problem...

Awesome, some more modifications for my cinitq then. Need to find the right wires thou hmmmmmmmmmmmm.

Good work Greenuns!


Title: Re: greenuns' build log
Post by: greenuns on May 09, 2007, 07:12:42 PM
thanks Chems, i hope it works for you too. Let me know :)

I tried uploading pics, but none of my pics came out properly and I had to return the camera, oh well...

I'm wondering if any of you guys experience the same thing but whenever I press down really hard,
the tablet doesn't register my pen...I''m not sure if this happened after I extended the wires or if it was already like this.
anyone experienced the same thing?

Personally with my first screen attempt, I've successfully used rc model cables, the ones with silicon insulation rated to high amperage. They work perfectly.

Yeah, its happened to people before.

Awesome!
