Anyway, after removing metal plate on the screen.
I meet the LED backlight again. Hello, long time no see!
Anyway, i should fill the metal plate part with other stuffs...
Cause I didn't want to buy foamex, I used several arcryl parts in my room.
It looks dirty, but ok. Anyway, this part is not visible.
Assebmling all together, and doing test.
Now, I design my case using AutoCAD, and send the drawings to a private company who have CNC and lazer cutting machines.
Anyway, after few days, I got my case.
It looks like this. The bottom is made by ABS, while other parts are made by arcryl.
The bottom has a hole and scoopped(?) part. (Please correct my English)
The hole is for the connector for the wacom plate and the wacom circuit board.
And the scoopped part is for FPC cable connector for buttons.
From this pic, you can see why i made above parts.
Anyway, you can glue ABS and arcryl very tight with chloroform.
And bore holes for screws using dremel and tapping screw.
Taping the wacom plate to prevent electric short.
And install foamex with knife cut to hold LCD.
But my hand is not fixed...
Anyway, LCD is fixed like this.
And to prevent it fall off from wacom plate, I glued them with strong double-sided tape.
With the trasparent top cover. It will be colored in(by?) black.
And before to order 0.7T tempered glass, I ordered 1.65T tempered glass.
I will explain why I changed the tempered glass later.
But anyway, I ordered a wrong thing. The size is 500x323, but I ordered 500x232 by mistake
Anyway, just install it to see whether the thickness is ok.
And, I tested withough glass and top cover.
When turning on, you can see AOC logo.
Through the hole on the bottom of the case,
The wacom plate inside the case and the wacom circuit board are connected.
And bore holes to hold SMPS and AD board.
At this moment (taking the picture), I had no idea that this AD board will be burned....
You see that scsrew?? On that screw, there was spark and both SMPS and AD board are fired!!!!!
Shit, they must use cheap circuit board.
Anyway, withought knowing the future, I was taking pictures....
And I also attached a monitor arm. In that picture, it was attached in reverse way
I modified it in final result.
Anyway, it is tightly held by screws.
So.... I thought this might be finished soon.... at that moment..
My hand may know the doom of this tablet... This pic looks sad..T^T
Yeah, yeah... until that moment, i was so excited.
Anyway, bore screw holes for top cover.
Boring holes is really boring.....be patient.
And color the top cover in black.
Actually........I recolored it more than three times.....
At first time, due to poor sandpaper work, the paint was ripped off, so recolored.
And then, during my DIY beam projector work, I chopped the top cover with my beam projector by mistake .... ... so recolored.
And......There were lots of mistakes during finish spray work.
So recolored...T^T Maybe I am stupid
Anyway, let's move on again.
This pic shows how i gonna hold buttons with screws.
I bored holes for screws on arcryl parts and glued on the back side of the top cover.
The shiny part is touch script.
Now, i can hold the button like this.
Took this pic with excited mind.
Didn't know that it would be take more than one month further...
Still excited, I go on coloring the tempered glass. haha
The button parts are not completed, yet.
The opposite part is same.
To hide the headless screw holes, I covered them with black stickers.
Time to attach the tempered glass with very strong double-sided tape.
I didn't know that this will cause a disaster....
Anyway, turning on the desktop.
And then, I found a very important stupid problem in my build.
When I tried to draw a straight line, the line is not drawn continuously but drawn with segments with some pulse shown in the example pic.
I found two reasons.
First, the panel is somewhat thick, so by adding 1.65T tempered glass, it is more difficult to transfer the pen signal onto the wacom plate. However, this is not a big deal.
Second, this is a real important issue. Since my case is purposed to reduce the thickness than that of the original wacom case, the insulatoin metal sheet is very close to the wacom plate. AND this leads to eletromagnetic interference between the wacom plate and the metal sheet.
By experiment, I found that the distance between them should be longer than 2mm. So I should disassemble all, and should insert 2mm thickness on the back of the wacom plate.
And,.....here is the sad story.
During disassembling them, I broke down my LCD... I tried to rip off the tempered glass from LCD, and they already glued very tight..
This shot is just before to break down the LCD....Sayonara....
AND, one more disaster...
I told you that I broke down ptz-1231w also. Here is the shot.
During test, I plug in and plug out the wacom circuit board a lot, and one of the connection pin was ripped off!!!! DAMN!!
So I tried to do emergency surgery with soldering.
And it had been dead with my cursed hand. Bye bye...
Sayonara again... to my closet.
So, I bought the monitor, and the wacom tablet again.
Start again from beginning... Jesus..
After few weeks, I bought AOC2269 again in 중고나라. And restart the work.
This is how to hold my pen. You can buy this from internet. Do not know english keyword, but in korean, 다이어리 펜 수납.
Anyway, red color is for man.
This is how to cover the back side of my tablet.
So, it has one power plug cord.
And one DVI port, and one VGA port.
Of course, chloroform is used again.
If you inject it on the edge you wanna glue, they are soaked in the surface.
ABS and arcryl can be glued tight with this method.
So, the SMPS and AD board are positioned like this.
The OSD button for the screen is attached on the side.
The button is extended using arcryl, and will be colored by black.
But, by mistake I lose one of them
It's missing upto now, I do not know where it is haha.
Anyway, the back side is colored by white surfacer and finished by non-glare finishing spray.
During this work, ptz-1231w is arrived from ebay. I love ebay so much.
And from now on, I am working very carefully.
This is the missing button. Where is it?
So after assebmling them, I can test without any problems.
At that time, there were lots of jitters since I hadn't found good screen frequency.
Anyway, at that moment, I was so tired and frustrated by many mistakes and my frined kept teasing me for my many mistakes.
So I took this picture, and send him. haha.
Dear Kim. this pic is for you, my best friend
The pen holder is red, but buttons are white....
I cannot stand it anymore!
So? Recolor them in red with non-glare finish spray
Touch script parts
Now, I can assemble all together.
But the tempred glass has 1.65mm thickness.
And as i explained before, 2mm thickness is inserted more than I expected to cure the big problem.
Therefore, the glass is projected out. So it looked ugly.
So, I contacted to the owner of the company who sells tempered glasses, and I explained my situation.
It is rare case to sell thin tempered glass to normal person, but he agreed to make 0.7T tempered glass for me! Wow thx for him a lot, I didn't need to remodel the case.
The 0.7T tempered glass costs more than 100$. but worthy.
Anyway, I need to wait more than two weeks again to get the tempered glass. Finally, I got it!! Yeah!!
This is really really thin, and it is like the tempered glass in iPad air.
Anyway, I tried to color it, and failed twice
I hadn't noticed the reason for the failure.
And found that.... My room has quite low temperature due to air conditioner. When I tried to color it, I go out with it.
And the outside temperature is much hotter than my room, so there should be lots of moisture congelations. That was the failure reason for coloring.
Anyway, after founding the reason, I go out when sunny day and colored it with success.
To color it well, you need to do with patience. Spray it little for lots of time.
Wow, it looks gorgues T^T
This touches my heart.
Fantastic back side!! with one button missing
With the monitor arm, i can adjust screen slope (is this correct word?)
I like my design
There is litte mistake on coloring, and there is a damaged part by my beam projector.
But it looks cool~! yeah!
Boot on Windows 7, I can use this as a monitor.
But, when I plug the tablet USB, blue light is on, that means the tablet is ready!
Very sexy pen holder (in my opinion)
I can become an artist with Sketchbook Pro (though I am not good at painting haha)
And it is jitter free! I adjust the screen frequency not to have jitters.
To do that, you must have a nvidia graphic card.
Finally, I wanna show you this. http://youtu.be/ipTl4P8zwVI
This is the end of story of my 21.5 inch wacom LCD tablet.
