Title: wei's iTab- complete
Post by: wei803 on May 23, 2008, 04:21:36 AM
The first attempt was done last year, one year has passed and I'll keep my words as never gave up on this project. This thread will mark my 2nd attempt to build a Cintiq. Things are still at early planning stage but one thing for sure the project has already begun after my purchase of the 9x12 Intuos 3 (again, since I've sold my first one) over the last weekend.

The last attempt failed (http://forum.bongofish.co.uk/index.php?topic=147.0) due to the LCD panel causing too much of interference to the tablet. Mouse pointer become jiterring non-stop & random mouse click.
(http://i2.photobucket.com/albums/y23/wei803/diy_cintiq/jitter_02.gif)

My plan for this round will be using laptop LCD panel. My research show me that:
- Take less power (might not bother much for now, but when I convert it to a tablet mac it does)
- Slimmer (also easier to break, ouch)
- Using single CCFL (yeah, less cable, less things to shield)
- No need FCC extension (funny that I only see a horizontal circuit sticking out of the LCD, no vertical one)
- External power ready
- Cables are already long enough
- No need for take apart (component come in individual parts, ie driver board, panel, lcd control buttons, power supply)

I've tested with a 12" LCD from an iBook, it works nicely with very minor/ close to no jittering, without any extra shielding. Best thing of it, the video cable and circuit was on top of the tablet when I did the test. A good start indeed. Further study show that the laptop panel are usually using good quality LVDS cable which are already shielded (http://home.comcast.net/~macdan/tibook_display.html#cables). Where by normal LCD monitor uses PVC/rubber protected cable.

But 12" is rather small, since I already got the intuos, my goal will be a 15" LCD like most of us. I have a choice of what type of LCD panel to use:
- UXGA (1600x1200pixels) superb screen with very fine pixels, but, will it be too small to work on? Someone have used such screen do enlighten me.
- SXGA+ (1400 x 1050pixels) cheaper, a more comfortable size to read & work on?
Dell website (http://www1.euro.dell.com/content/topics/global.aspx/vectors/en/2002_lcd?c=eu&l=en&s=gen) have a nice explanation on this.

Now let's say I go with SXGA+ LCD panel, then I need to get matching driver board as well. Already found the source for the board on lumenlab forum, which come with DVI, VGA & RCA video-in. Good enough. I've also specifically not to pick Samsung panel, due to the last failure. I'll go with LG panel, same one used on iBook & PowerBook. But this is still a gamble, like some of us proven that at higher resolution, the greater the interference. So wish me luck.

I'm in the midst of funding to get the panel + driver. (Yeah, another poor designer here). Should be able to make the purchase sometime next week.

If things ended up well, you should see a convertible DIY Cintiq/Mac Tablet in the next few months.

While waiting for the money to fall from the sky (yeah right). I have some idea brewing in my mind...
Stage1 - the cintiq
- I will try to keep the Intuos3 casing as it is, I think it's good enough.
- The LCD driver board, will have to stick at the back of the intuos. To protect it, I plan to use aluminium sheet (more on this later).
Here's a rough idea, sizes are not to scale:
(http://i2.photobucket.com/albums/y23/wei803/diy_cintiq/maccom1.jpg)

Stage2 - the mac tablet
I might be able to pick up a 1st gen MacBook with a dead screen. Planning to integrate on to the back of the Cintiq. Might also want to power the LCD driver board with the MacBook (will go in details later, if I'm able to get the macbook).

Stage3 - the cosmetic
The last part should be tidy up here and there, spray paint. While waiting for stage1 & 2 take place, I've come up with some draft logo :)
(http://i2.photobucket.com/albums/y23/wei803/diy_cintiq/skull.jpg)

------------------------------

29 May
Made up my mine and ordered the UXGA panel with DVI + VGA driver board. Now waiting for salary to pay for it. Item should arrive in 2 weeks. That should be sometime mid June.

Meanwhile have engage a company in US that provide metal furnishing about getting the customize Aluminium panel. Will see how it goes and hope it won't cost me my arm & leg.

Alternately, I might recycle the casing of 15" Apple Cinema Display. But need to look for one that's cheap enough.

------------------------------

30 May
The helpful seller sent me a photo of the LCD panel and driver board. Looks exactly what I wish it will be. BOE HV150UX1-101 UXGA panel no need for FCC extension. DVI + VGA LVDS board that's in small form factor. External power. All cables are long enough for the project!
(http://i2.photobucket.com/albums/y23/wei803/lcd-panel.jpg)

------------------------------

3 June
Found a fabricator for aluminium sheets, been lias with them for pass 3 days to get the drawing done correctly. The aluminium sheet will be my back cover where the LCD driver board located.

------------------------------

5 June
Received the LCD panel kit yesterday. Excellent screen. Initial test still give me some jumping mouse pointer and random click. Will do further test today if I have time.

------------------------------

7 June
Screen test very successful, I get close to no jump. But when the pointer get too close to the CCFL & LVDS random click appear. I can still improve the shielding. Already cut a hole on the inner plastic of the Intuos. Next is to cut a hole for the Intuos faceplate. The thickness of the LCD panel fit just nice! Here's some shots of LCD test.

------------------------------

9 June
Success success success!!!
(http://i2.photobucket.com/albums/y23/wei803/diy_cintiq/yeah.jpg)

Manage to done almost everything today. But still alot to tidy up. But very happy with the result.
The bottom temporary setup, where the LVDS driver board located.
(http://i2.photobucket.com/albums/y23/wei803/diy_cintiq/back.jpg)

I'm re-using the Intuos clear case. Use thinner to wipe away the silver/gray paint coat and I get a strong and nice "window" for the LCD. No need for cutting a hole nor headache for protection sheet.
(http://i2.photobucket.com/albums/y23/wei803/diy_cintiq/close.jpg)

Here's another shot:
(http://i2.photobucket.com/albums/y23/wei803/diy_cintiq/success.jpg)

Next should be tidy things up when the aluminium back cover arrive.

------------------------------

11 June
Further test was done with various Mac with different configurations:
- Mac Pro, Full res 1600x1200 give fast random mouse jumping in 0.5cm radius, not very usable. Acceptable at 1280x1024. Still some slow and small jumping.
- iBook G4, only support VGA at 1024x768, but very good result, but no screen rotation, I need 180 degree rotation. Close to non mouse jumping.
- MacBook, similar result as Mac Pro but better result. I can still use it with full 1600x1200 resolution.

Next, I've decided to call this project iTab (Wei DIY Tablet).

(http://i2.photobucket.com/albums/y23/wei803/diy_cintiq/skull2.jpg)

Planning for the stand.
------------------------------

15 June
repainted the cover today after the failed attemp to wipe the wacom logo:
(http://i2.photobucket.com/albums/y23/wei803/diy_cintiq/smere.jpg)

here's how it looks like when all paint are clean off:
(http://i2.photobucket.com/albums/y23/wei803/diy_cintiq/itab1.jpg)

spray painted to black. done a lousy hand-drawn logo:
(http://i2.photobucket.com/albums/y23/wei803/diy_cintiq/itab2.jpg)

and lastly, preparing the macbook:
(http://i2.photobucket.com/albums/y23/wei803/diy_cintiq/itab3.jpg)

------------------------------

16 June

Stage one are more or less complete. Stage two involve planning to house the MacBook together. Here's what to be done:
- Holding the MacBook, facing the keyboard side to the aluminium plate (better heat transfer?), but I wont be able to access to the keyboard & trackpad (which I don't need). But I still need the power button...
- Power botton relocation, this is a bit tricky. Anyone with a powerbook scrap wanna donate the power button?
- Extending the ports. I will allow the CD-ROM slot facing out. Where all the ports facing inside, which I need to extend to allow access to them (network jack, firewire, USB). Might need to DIY, but no worry.
- Infra port, this is a hell of pain. Anyone know if I can reflect the infra red signal? Let say I use a clear tube to redirect the infra signal to the hidden receptor? Else I might live without it.
- iSight camera & microphone. Have already tested this, need to reroute to the front side. And drill a hole on the clear case.

------------------------------

18 June
Just done my shopping for some final parts. Adapters, cables, grille for the last part of the project. Hopefully will received them in 2-3 weeks. I've also decided to remove the combodrive and replace with a 2nd internal harddrive. In this way, I can let the CD-ROM side facing inward.

------------------------------

19 June
Aluminium back casing arrived at airport 11am today according to USPS tracking system. Hope to received it this week. Else it will be next week.

------------------------------

20 June
Wow, this is really fast, the item was cleared from airport custom should be on its way to my house. High hope to get it today or tmmr.

With some adjustment to Wacom driver, I manage to reduce to jitter to very minor. Only obvious when pointer near the bottom & side of the screen.

------------------------------

21 June
Here's roughly how my current jittering at 1280x1024 resolution:
(http://i2.photobucket.com/albums/y23/wei803/diy_cintiq/jitter.gif)

Drilled a small hole for iSight camera. I get blurry images under the thick acrylic case.


------------------------------

25 June
The aluminium plate arrive on Monday, done a very rough tape test. I'll let the photos tell the story.

Front view:
(http://i2.photobucket.com/albums/y23/wei803/diy_cintiq/itab-1.jpg)

Back view:
(http://i2.photobucket.com/albums/y23/wei803/diy_cintiq/itab-2.jpg)
The air vent holes is off. I'm not sure what went wrong during the production, the holes should be in equal size. I've notify the fabricator. Waiting for their reply. I've re-use the 4 rubber strip from the intuos.

The stand:
(http://i2.photobucket.com/albums/y23/wei803/diy_cintiq/itab-3.jpg)
Supposed to be a vertical wall vase hanger from ikea. It's cheap and hey it's aluminium ;) I've bend it a bit to make it fit my iTab.

Using the stand:
(http://i2.photobucket.com/albums/y23/wei803/diy_cintiq/itab-4.jpg)
This stand is not really portable, should stay on my desk. Have an idea to fit in another stand at the back of iTab.

The logo:
(http://i2.photobucket.com/albums/y23/wei803/diy_cintiq/itab-5.jpg)
Brush the logo on with masking film + sand paper.

(http://i2.photobucket.com/albums/y23/wei803/diy_cintiq/itab-6.jpg)

The MacBook:
(http://i2.photobucket.com/albums/y23/wei803/diy_cintiq/itab-7.jpg)
Temporary held with masking tapes. Will re-position it later. If I keep the ports part facing out like this, I will get the Mini-DVI to DVI adapter & firewire exposed, not very nice. Will have to go back to initial idea where the CD-ROM slot face out, ports face in. When facing in, I will have to extend some of other ports that's not connected internally, like the ethernet, sound, mic, USB & firewire. (note, I'm stealing 12V from the FireWire port, have to do some modding there).

------------------------------

26 June
Tried to reposition the MacBook lastnight, doesn't work. :( Oh well...
Installed a Seagate 7200.2 200GB drive into the MacBook, very speedy indeed.

------------------------------

27 June
Installing & tuning softwares:

------------------------------

7 July
Aluminium grille sheet arrived today.

------------------------------

8 July
Finally it's done.

Optical drive bay facing out.

(http://farm4.static.flickr.com/3216/2651520279_277600c0da_o.jpg)
The ports side. All port you see here are extended or repositioned. I've extended the FireWire and stealing the +12V from it to power the LCD panel. One USB port are connected to the intuos internally and another one was extended. Yet to do the headphone jack and ethernet port. Will live without them at the moment.

(http://farm4.static.flickr.com/3126/2651519839_db34383254_o.jpg)
The back, clearly showing the grille in place. The tape you see at the upper right and lower left are the power-on button for both MacBook and LCD. Will tidy them up once I get the idea what to put as button.

OSX and iSight in action.

And one last photo to conclude this project!

Remarks
- I still get jittering when the iTab run hot. Air-conditioned room FTW.
- I get 2 horizontal black line because I accidentally presured the LCD circuit, have to live with that.
- In order to get constant 12v from firewire I need to keep the magsafe adapter connected and powering the macbook.
- Airport get weaker signal due to covered by the aluminium plate.
- There's some dirt & minor scratches inside the frornt cover. Visible on bright background.

Nice.

You Should make it Apple.com.

I always found Mac.com to be awkward for some reason :\

I really love the logo, but after one of my classmates made the remark now I can't see anything but a phallic object when I look at that bone-pen.  ::)

Can't wait to see this one progess.

Cheers,

Thanks for the input guys. Anyway, the logo is just to kill time, will ignore it at the moment.
Panel will ship to me by today if things goes well.

Post by: Drewid on June 07, 2008, 02:54:57 PM
Looking good. Good shielding makes a real difference.    SO what flavour of mac is it in there?   I really like the idea of a self contained drawing device.

Look awesome. I hope to come back from vacation to a completed build ;)

What LVDS controller is that? I would LOVE to have DVI.

Post by: Switz on June 08, 2008, 02:09:52 AM
Sorry to inform you.  Rumors have been going around that Apple is dropping .mac (not necessarily Mac.com, but...)

Post by: wei803 on June 08, 2008, 04:23:00 AM
guys, let's put the Mac thing aside ok? I'm going to remove the image. let's focus back on wacom.  ;)

drew, I've got the MacBook. The screen was dead, it's just nice to be fitted behind the intuos. But the whole thing will be super heavy.

claymonkey, I've took this photo to show you the board:
(http://i2.photobucket.com/albums/y23/wei803/diy_cintiq/board.jpg)
It's really small, only at 10.5cm X 5.5cm. Come with DVI, VGA, backlit inverter (separate board), control strip. Support rotation (90, 180, -90). Powered by a 12V external brick.

The alloy furnishing company just informed me the back casing will ship by friday.
It will be 1-2 weeks before arriving.

Super Work!

Post by: wei803 on June 12, 2008, 03:03:54 AM
Thanks guys. It was a gamble for me. I never know it will works. I was lucky as well because the top most gray "drawing sheet" was only stick-on with double-sided tapes. My first Intuos 3 was glued with super glue right in the middle. And I'm not sure is it possible to clean the glue stain for the old one.

I've tried many liquid before a success. I've tried alcohol, spirits, liquor, nail polish remover (thinner), petrol. Only thinner works. I will take some photos later, the cleaning wasn't very nice, there's still some stain & scratches visible, but not very visible once the screen turn on. Those that would like to try my method, just be sure you do not scratch that part when taking the Intuos3 apart.

Man oh man that's beautiful.
So did you mask the edges while using the thinners?


Title: Re: wei's DIY cintiq strikes back! (2nd attempt - updated 9th June) SUCCESS!!!
Post by: wei803 on June 13, 2008, 02:09:07 AM
Yes ofcourse, but it wasn't very nice strait line. Thinner seems to leak under the tapes.
Lastnight I try to wipe off the WACOM label and replace with my own logo. I failed, hahaha. Thinner leak onto other part and it looks awful on top.
Will wipe the whole thing clean, mask and spray a new paint coat. I think that should give me better result.

Post by: Switz on June 13, 2008, 03:11:04 AM
You should spray it with something crazy.  Find like a rainbow spraypaint (does that even exist).  Then overlay light gold and silver sparkles.
lol, I am bored....

Thanks guys. While waiting for other parts to arrive (from around the globe), I've done some test to see what actually causing the jitter on my build.
- Driver board away - no change
- Unplug the backlit inverter bundled and use the inverter from my laptop and drive the backlit - no change
- Adding aluminiun sheet as padding for the driver board & inverter - no change
- Using a different CCFL backlit (taken from a faulty laptop screen) - no change
- Totally unplug the backlit (dark screen) - no change
- Powered from different sources, tried 2 different 12V adapter, also modified a firewire cable to steal power from my computer - no change
- Also tried aluminium foil wrapping various cables (USB, DVI, power) - no change
- VGA seems to give less jitter than DVI

To try:
- Different DVI cable (shorter, longer, different brand, gold platted, you name it).
- A cold start without inverter & backlit to confirm is it the heat from CCFL causing the jitter.
- Power source from different building

Post by: Drewid on June 19, 2008, 01:17:18 PM
I take it the foil shielding wase grounded/earthed and all that.

Might be worth trying lead foil, the sort of stuff you get for flashings on guttering and such like.

the refresh rate also influences jitter.  I set my video card refresh rate to maximum for my dontiq and the little jitter I had almost vanished.

That is fantastic isn't it.  That's a really finished piece of work, and 1600x1200 too.


 So what was the panel you used in the end? And was the LVDS controller board from ebay?


Title: Re: wei's iTab- complete
Post by: wei803 on July 10, 2008, 09:43:41 AM
Thanks guys, the panel is BOE HV150UX1-101 UXGA. Both LCD panel are from a seller I found in lumenlab forum. Strangely, I couldn't find anything about this guy in lumenlab anymore. Not sure did he stop selling or what. But I got his email & MSN: cityhunterbj(at)hotmail.com

Try contacting him if any of you interested to get LCD panels. Do proceed with care. Not sure what went wrong with him and lumenlab forum.

Post by: kubi on July 11, 2008, 12:48:57 AM
wow that is uber cool, my first comment after years ;)
the panel is nice, maybe i'll get one, i'm looking for dealers here, but no price-tags have to ask them....


Title: Re: wei's iTab- complete
Post by: wei803 on July 11, 2008, 02:16:57 AM
Hi thanks, do try visit lumenlab.com forum they have plenty of bare LCD panels for sale. No stripping and such. Good thing is most of the panel doesn't need FCC extension.

Hi this is a bit off topic but how do you find running photoshop on an Ibook? I'm thinking of using a smashed up ibook for my build a g4 1.33 ghz 12.1" one just wanted to know how fast it is for some basic photoshop work?

1.33 G4 should be sufficient to run Leopard + CS1-2. Max out the RAM to 1.5GB. I would not suggest <G5 machine to run CS3.

I would not suggest to push that poor thing that way. Apple lock the firmware so the VGA out only capable of doing mirroring internal display. Meaning max 1024x768px is what you get. But there has been a firmware hack (http://macparts.de/ibook/) to enable spanning plus supporting higher resolution. It's not a 100% safe hack. Some user reported good results, some as bad as frying the mobo.

Still some tweak but very minor.

Well...may I ask you what type of UXGA panel u used ?
I'm planning since some weeks to build one cintiq on my own and this mac tablet just looks as beautiful as nothing else...i hope I can spot some lcd-broken macbook outta there ;)

But the first thing to go is the wacom and the "TFT".
I think I have to bite the bullet and buy a used Wacom tablet for about 200€ here in Germany, cause no- and I mean NO - international seller wants to ship to europe :/

But besides that I've spottet many UXGA displays on ebay and elsewhere and I'm not sure which one to buy... there are several used ones, built out of there IBM cases, costs ~ 90€ each and many many new ones pricing from 130 up to over 300€, where I'm not that sure which one I should take, with having an eye on my pocketmoney as student... ;/

I would be very glad if I could get an answer from an expert on this territory :]

Greets, Julian

The panel I'm using is BOE HV150UX1-101. Do bare in mind if you buy a panel is the panel only you will be getting. Where these panel supposed to go into ready made laptop as replacement/upgrade. So please look for kit set where you get the VGA/DVI input drive board bundled and pre-programme for you as well. Unless you're very sure what you doing. All LCD panel need to be driven by a driver board that output correct frequency in order to work nicely. Getting the LCD is easy and like you said they are everywhere. But getting the right driver board is a very different story.

Post by: m0x on July 23, 2008, 02:57:32 PM
thats good to hear.
So for time reasons, could you - if you remember - send me the name of the driverset and kit you were buying as PM and maybe even where you get it from?
As you said - I am not thaaat sure what I'm really doing - I maybe need some more help by this, cause I'm studying cognitive sciences and want to study art in the next years and not computer technology O:-)  ^^

But thanks so far, your "iTab" just looks awesome, I really really love it... =)

Greetings from Germany, Julian =)

Umm that was a modding contest right?

I think you should have gotten way higher. I mean the number one guy didn't really mod anything, being as it was really more of a hack by changing some code. TIN coated iPhone was pure poo. Don't get me wrong TIN is the bomb, but he himself didn't do anything. He got it coated. He modded nothing. All it did was say I have too much money to play with, to me. You actually made something form other somethings. You got two very separate things to dance a beautiful dance together.  How can people not recognize that is 80 hundred million times way kewler.  :(

iRoc, thanks for your kind reply. Well I believe the judging are fair. Maybe they have their own guideline on how a mod should be. Anyway, I wasn't building to enter their contest, was so happened I came across the contest during my research. But I am really disappointed by the organisers as until now I haven't even receive the entry gift that I'm supposed to get last year. Looking at this I won't submit any of my work to the contest.

Can you please tell me which driver kit and where you bought it from?

Hi, sorry for getting back late. The set I have are DVI + VGA driver board. The simplest one I can get. Come with control strip, backlit driver, the main board and 12V power adapter. I bought it with the LCD, matching LVDS cable was provided as well.

Looks amazing Wei, real nice.

I have been using the same Intuos 3 for years now and recently been checking out the 12/21" Cintiqs. Am a bit worried by some comments about jitter and stuff with the 12" and the 21" has been sold out for a while and they say it won't be available anytime soon :|

I'd love to get a new Intuos 4 to work on, and do your part 1 of the build to the Intuos 3 and take it home for some casual couch painting :)
I wouldn't place a laptop onto it, there would be a small HTPC nearby. How does your final build do, regarding jitter etc if you'd leave the laptop on the backside out?

Been ages since I did a mod, but this one is hard to pass up..

Welcome Heiron!

So do I understand correctly that you want to do a "DIY Cintiq" essentially? This forum is dedicated just to that task. :)  You may look around a bit. There is also a mini wiki.bongofish.co.uk that is its infancy but contains a few things too.  Ask away! :)   There is also tabletmod.com that you could check out. (One of our member spin-off)

Hi Bernard!

Thanks, and I did check out the forums and I really like it so far :) A DIY Cintiq is exactly what I need indeed.. esp. with the wintermonths coming up and a new effort to not be in my office all the time yet still have the feeling to do something remotely usefull yet fun at home on the couch. (not much a of a TV person)

I'm especially drawn to the mod by Wei since I have the Intuos 3 involved, love the resulting look and it seems to have been quite succesfull. There are alot of open questions still though, so may have to open a thread for it perhaps.. and not spam Wei's thread too much.

Open questions would be
-the amount of jitter for Wei without the laptop nearby
-any issues with reading height for Wei?
-good panels to use (I prefer a high res one like Wei with decent viewing angles.. possibly) (MacBooks have really nice ones, but common laptop screens are so so)
-what drive board to get
-is it possible to get the Intuos 3 back together and alive if the mod doesn't work

But I guess time (actually, more likely friendly board members :)) will tell. Am on a Uni so got access to some nice equipment (heck, a top class cleanroom if I wanted :P)..  For now in some spare time trying to get a grip on what would be needed and my odds of killing the LCD panel before it is done :)

Yes, you can start a "build" thread if you intend to go for it.  Posting into others thread is good to get the attention (not everybody watches all threads).

Wacom tablets are solid beast and you can always rebuild them easily without a problem -- the only problem is voiding the warranty if this is a recent purchase.  Some Wacom board died but it is quite rare and it was stuff like high-voltage crossover with the inverter or stuff like that.
