1  Screen Tablet malarky / Monitors / DVI doesn't allow V and H positioning ? on: June 20, 2014, 11:23:01 PM
Hey guys, just wanted to check, for those who use NYJtouch controllers, when you switch to DVI, are you still able to adjust the V and H position of the screen? For some reason my is greyed out when I use DVI. Just wanted to check if its just me, cuase I'm having a hard time calibrating the screen without being able to adjust that.

Update,

Took the whole thing apart and redo some of the shielding and grounding. Found out a lot of the random clicks and jitter were caused by poor grounding.

Calibrate the whole screen to a 1:1 ratio, redid all of the copper taping, solve almost all of the random clicks and manage to get the jitter to a minimum level, around 1 pixel jitter , 2 pixel around the TCON board and ccfl.

The only problem is after a while, there will be a jitter spike where the jitter just jump like crazy for about 5 - 10 mins before going back to normal. Still can't figure out what is causing this, my only guess is maybe the LCD controller is not properly shielded since unlike the K-jintiq, and the cintriq 2.0, I couuldn't get a teko box or anything similar in my local store. Maybe I'll try to look for something with similar characteristic as a teko box and use that. maybe an old DVD player? Salvage the casing and cut to fit? Not sure yet, so for now I bought Lazy Nezumi to solve the jitter, although when it spikes, it still shows, but its enough to get it to work.

Some final images


Have it on an ergonomic laptop stand


Probably not gonna paint it since my room is pretty dark anyways.


Drew this as a test Cheesy


Also, wanted to thank Aerendraca again for sharing his vast knowledge on the subject matter, without him properly wouldn't have gotten far, thanks again mate! Cheesy

And thp777 for finding the CRU program ^^

Properly gonna call it done until I manage to fine something to properly seal the LCD controller board and pray all the jitter will magically disappear ;_;

Thanks a bunch for the tip guys! Cheesy

All right, quick update, so some changes that I've made so far
- Change from VGA to DVI cable,
- Removed the metal bezel that was housing the ccfl, and wrap it in aluminium foil, with 2 pieces of plastic pushing the ccfl down towards the panel
- Shielded the TCON board as Aerendraca suggested, but gonna try thp777 method since the jitter is still present.
- Finally got the CRU softwarre to work properly, increase the refresh rate to 3hz, which seem to remove a lot of the jitter.

Theres still a few problems, the jitter is almost non existent now, except when the LCD panel starts to heat up, then the jitter is back. A lot of random clicks on the upper 1/4 of the screen.

The only thing I haven't done is house the LCD controller in some sort of insulated, aluminium enclosure. I'm having a hard time finding one in my local vendors or one that ships internationally online, so for the time being, I just have a bunch of aluminium wrapping the plastic container that I have it in. If anyone can point out what else I need to do or correct please let me know! Cheesy

@ Thp777, Thanks for the link! I tried setting it to 59hz, and 66hz, unfortunately, not much changes happen. For some reason, it also off set the screen, making it large, therefore unable to fit the entire screen to the panel. I'll play around with it a little bit more and see how it goes.

Yesterday, while using it for long periods, the jitter start to spike when the lcd heats up. I tried shielding the LCD controller as suggested by Zithe1, but that made little difference so far as well. I'm going to pick up a DVI tomorrow and tried it out, as some has suggested DVI help reduce the jitter a bit.

I should also mention that I keep the metal bezel that holds the ccfl together. Cause when I remove that part, I wasn't sure how I would hold the ccfl in place. Should I remove the metal bezel? It does make the jitter worse when the cursor is close to it, but im not sure if removing it will reduce the overall jitter. Any thoughts?


This is the jitter so far




Quick question, do people usually shield the areas I have circle? From what I see, I don't see anyone doing it. The only major difference I'm seeing so far is most people use an aluminium/metal casing to house the LCD controller where else I'm just using a lunch box that is wrap in aluminium. Do you guys things that is relevant to whats causing the jitter?

@ zithe1, Thanks for the info! I'll try wrapping the VGA controller with some aluminium foil, to see if that helps. If not, I'll just need to get an aluminium casing then

@ Aerendraca, Yeah, and i check their FAQ, they don't seem to be planning on making it compatible with win8 as well. ATM I'm trying to find an alternative.

@ thp777, My AMD control panel doesn't give me that option, its stuck at 60hz. If I try to force it, the resolution would change to wide screen ratio.

Aerendraca, you sir, is a life saver! I couldn't thank you enough for your help! ^^

Did everything you told me too and the jitter drop significantly. Shield all the wiring with aluminium foil and wrap them in some duct tape. Also I just place a bunch of A4 printing paper in between the lcd panel and the wacom digitizer. Hopefully its thick enough and the heat wont go through.

I've been trying to change the refresh rate, but powerstrip doesn't seem to work with Win8, whenever I open the program, my computer just lag real bad. Trying to find an alternate way to lower the refresh rate and hopefully it will solve the jitter and random clicks for good.

Gonna keep working on this until I can rid most of the jitter to a point where I can draw comfortably . Any more tips and advice is always welcome guys!

Hey guys, sorry I haven't been active, work had me busy this past few months.

@ Aerendraca, Thank you so much for you tips and advice. I'll be reworking a lot of things with your advice. I'm actually not sure what I should put in between the screen and the digitizer? I'm guessing a sheet of aluminium foil is a bad idea? or would that be ok? I haven't had the time to do the fixes yet, but I'll update you once I've shield the wires. Thank you again for your help!

@thatcomicsguy, Thanks for link! I chose these parts because there have been multiple successful builds with it already. I'm actually having trouble with Powerstrip. I couldn't find a proper guide to lower the frequency, and whenever I do anything with it, the screens will start flashing.

I'll be posting another update soon!

I took your advice Aerendraca and bough a conductive adhesive copper tape, couldn't find one in my local store so I had to order it online, which took forever!

Now that I finally have it I tried to tape it to the back metal sheet, but no difference, so I tape it again to the wacom digitizer, which gave some very slight improvement, but not much.

I should probably mention that I kept a small chunk of the metal bezel to hold the CCFL in place on the panel, so jitter on the very top of the screen is to be expected, but I'm trying to get it so the mid-top to lower area have minimum to no jitter if possible, cause I'm planning on using this for sketch and line work.

I've also tried powerstrip, but I can't seem to get anything below 60hz, is there a detail guide how to go about it?

Thanks Bernard! I gave that software a try and mess around with it but no deference in the jitter. I'm guessing is because I havent grounded the LCD panel yet.

Speaking of grounding, I have been looking at the K-Jintiq, Lunatiq and Cint®iq 2.0 threads and they all use a metal encasing on the back for the controller board. I couldnt find any so I was thinking of what Aerendraca said here about connecting both the wacom digitizer, and the LVDS to the metal reflector plate at the back of the wacom digitizer to ground it.

Do you guys think if I use a copper tape to connect the TCON board to the metal reflector at the back (view the red square in the attachment), would that help ground both LCD and Wacom digitizer?

I'm probably just gonna glue the controller to the back and close it up with a lunch container.

Thanks for the advice Aerendraca! I'll post more questions and concern up in my build log for help  C:
11  Screen Tablet malarky / Build Logs / Re: DIY-TIQ! (ughhh.. need to work on the name) on: November 25, 2013, 12:27:25 PM
Thanks for the suggestion bumhee34! I'll try it out later and let you know what happen C:


EDIT: Thats odd, I cant seem to lower my refresh rate, its stuck at 60hz. Is there a third party software or a work around for this? I have an ATI card but thats also showing 60hz as my only option.
12  Screen Tablet malarky / Build Logs / DIY-TIQ! (ughhh.. need to work on the name) on: November 25, 2013, 08:43:30 AM
Hey guys! So I've been stalking this forum in the dark for a long time and now that I finally have all the necessary components to build my own DIY-TIQ! I thought I'd start a build log, and hopefully get some help as well, cause I dont know what I'm doing half the time.

I'm basing my build on K-Jintiq like many others, I'll just repost the parts I'm using for the sake of convenience for others

- Wacom Intuos 3 12x9
- 15" S-IPS 1400x1050 LP150E05-A2K1 panel
- NJYtouch RM5451 w/ audio controller board.

OK! So, I actually should have started this build months ago, but at that time I bought the wrong screen, which if for another IBM 15' laptop, but the resolution was lower and the colours were terrible. So I had to save up money to get a new screen and get the programmer from NJYtouch to reprogram it for the LP120E05 but the programmer was buggy as hell. Only until yesterday, I manage to get the program to work correctly.

So far I've already strip the tablet down, and prep the screen, cut all the plastics, and removed the paint from the clear plastic.

I'm kinda at that point of just putting everything together, but when I hook it up for testing yesterday ,it worked!....kinda. There was a lot of jitter, but its definitely looking pretty good so far. I'm not really sure what type of material I should use for shielding the wires and isolating the lcd panel from the wacom digitizer thingy. So far I'm just laying down a bunch of sheets of A4 printing paper, but I'm not sure how long that'll last. I was thinking of using Aluminium wrap for shielding but..does it work? Not really sure, I'm a real newbie when it comes to this but if its for the sake of improving my work flow and quenching my thirst for a cintiq, I'll give it a shot :C   
13  Screen Tablet malarky / Heyaaaalpppp / Re: General question about shielding on: November 24, 2013, 09:31:02 AM
Thanks for answering my questions Aerendraca. I'll work out the shielding as I go.

As for grounding, are there any particular methods or any precaution I should take when building my DIY cintiq? Or rather, is there a more specific example of how to join both the LCD and wacom digitizer to an electrical conductive shielding material?
14  Screen Tablet malarky / Heyaaaalpppp / General question about shielding on: November 23, 2013, 08:29:29 AM
Hey guys, so my screen finally arrive today and I'm about to start building my DIY Cintiq (base using the K-Jintiq)

I just have some general questions regarding shielding the wires and grounding, etc. I'm not very good with this stuff, and I really dont want any circuits to be burning when I turn this thing on. Soo... yeah, any help would be awesome! Cheesy

Questions!
1) Is there anything placed between the screen and the actually wacom tech board? I was thinking of placing some sheets of paper, will that do?

2) Is shielding general referring to separating the individual wires to prevent interference from one and another? Will using aluminium wrap (typically for food) work? What wires should I be shielding and more careful with.

3) Grounding, if I'm not mistaken is when we make sure the wires and electricity are connected to some sort of non conductive material that is touching the ground? Please clarify if I'm wrong.

I'll probably have more questions as I start working on this, but for now, if anyone could help me clarify these points, I would greatly appreciate it!
15  Screen Tablet malarky / Monitors / Re: Bad panel or wrong controller? on: June 29, 2013, 05:25:22 AM
Yes you are right actually! Its just a metallic tape, but just wondering as Im actually trying to fit everything in the intuos 3, I wanna remove the metal frame like what the guys did for K-Jintiq, but Im kinda puzzle as I really dont wanna break the panel. Is there a guide out there to remove metal frame?

Or is it just pray out all the metal only? There are a lot of plastic segments and tape that I dont wanna touch without knowing what they are ^^;

Edit!

Good news! Looks like its actually the LVD cable that was causing the flashing and jitterness. I hook it up again and whenever in grab the wires together on the lvd all the flashing and jitter disappear. Lucky i order another one along with the programmer!
