1  Screen Tablet malarky / Heyaaaalpppp / LVDS controller burnout on: August 08, 2011, 08:19:16 PM
Hey guys

I finally found a few minutes to work on my build this weekend. I was working on it for about an hour with the controller hooked up the outlet, screen, and computer. I got everything aligned perfectly, almost 1 to 1 on the screen, and got taping before anything shifted. While trying to align the led string at the top before applying the last bit of tape, my lvds controller went up in smoke. Big cloud and sparks, right in the middle of the board next to the copper coil where there's a plastic square (now with a melted hole). I unplugged everything immediately and there was no damage to anything else (me or my electronics). I used an appropriate brick (not the one the company sold seperatley, but one I had with proper specs). The controller itself was hot enough to burn, but I don't know if that was from a malfunction, the normal amount of heat it would produce, an effect of the weather (though it was 20+ degrees cooler than earlier last week), or a combination of the three.

So any ideas why/how this happened? I ordered this one from NJYtouch, so I'll have to wait another three weeks if I reorder from them  =_=.

I'm not disputing any of that. I was just listing a few things so you can find the right parts for your build. Like looking through websites that list the data sheets for lcds, looking through different sizeswhich will still work and look perfect with a 6x8,  and expanding your parameters slightly during product searches. I'm not saying to change WHAT you want, change how you LOOK for it and DESIGN around it.

 It's just natural to warn someone when dealing with electronics, even if they know what their doing (it's human nature).

There's a number of them on eBay UK right now. One's ending in 13 hours is around £400. Someone's just listed one and it's starting at 99p (I know it WON'T stay that way). There's even a 21UX as well. I suppose the real question burning in the back of my mind is "if they're so good, WHY are people selling them?" No use for them anymore? Not quite what they expected? Any particular underlying issues? Can't justify the cost. At least with a DIY one you're building it YOUR way and you have the chance to improve on what Wacom didn't do right. I mean, really, who else but someone SERIOUSLY interested in art and/or design would cough up the money for one?

Those are generally actual retailers, or people who buy them on consignment to make a profit. Even with the 0.99 start bid they usually finish close to the actual worth and aren't worth looking at for a bargain hunter. By rare, I mean an honest-to-goodness used cintiq. People generally don't give these things up. When the do it's because they need quick cash on a large ticket item, they've upgraded to larger unit, it's 20 years old, etc. Just like anything else, it rarely has to do with  product flaw.


If you have the skills to work with resin and similar material, you personally have the ability to make a professional finished product ~ just make sure you leave an access point in case, say 5 years from now, a normal wear and tear type of situation occurs (lcds can burn out in normal uses too) . I'm working on my own intuos3 6x8 project with a 10.1" screen, so I can check any measurements if that will help. The intuos3 is as thick as a relatively thin notebook, so adding a 5.5mm screen and little amount of resin won't be that different from what your describing. Just put the wires and control on the side of the intuos inside your resin case. Or carefully arange things inside the wacom case if that's your route.

Getting upset over an lcd you haven't bought yet isn't the worse you can come across in this project. We're talking about live wires and delicate crystal displays, dangerous stuff if you're not careful (ask anyone on the forum). But you'll be fine as long as you apply some basic problem solving and thorough research before any purchases,

Bernard is just trying to warn you of the risks we all assume with a  do-it-yourself, things break, people get shocked, etc resulting in extra cash and time (and occasionally band aids). But your working on a smaller than normal project, whose items are relatively cheaper. Depending on your choice, a 10.1" shouldn't run more than $70, any where from $25-$65 with shipping.

I don't have the time/patience/contacts (I get old phones from people instead of laptops with salvageable screens) to make a dirt cheap one myself, just as cheap as I can with the quality I want.

I'm more of the mind of "if I had that kind of spare cash in hand, I would want ____ more", ____ when talking about electronics would be a really good computer. Which is easier to find at that price, at least the parts, just because used cintiqs are too freaking rare.

768x1024 is a little odd of a resolution(at least around here), few monitors that I saw use it for their native specification. Most of the 10.1" (and others) that list it are actually misrepresented. A newer led screen is sharp already, maybe you should change the "768" part of your requirement. Go a little lower or higher, but check the actual inch or cm measurements.

If your going to modify for your own artistic purposes anyway, it's even easier to use an alternate size screen. You could even leave the wacom case intact and build you ideal around it. Just take into account the necessary space for the controller, wires leading out of the case, and depth of the screen.

Focus on the details of your ideal screen then look for those in a .1-2 bigger/smaller form.

BTW, getting a screen overseas is not a problem. All LCDs you can think of were manufactured "overseas".  Sending a package in the same city is not much different in terms of handling than going on a plane or a boat. The problem is not the oversea travelling, it is how it is packaged.

Even by the slowest method (2 months by ocean) I've never had my delicates break.  The one exception happened when something was opened by customs (random checking because it was the cheapest option) and the packaging was removed, then dropped/broken several states over *facepalm*.

maybe you can get away with 600$ price.

Dang it, Bernard ~ do you have mad shopping on top of soldering skills!? In all my time looking, I couldn't find one below $800 range. I know it's possible (saw an old one go for $450 once) but I have not personally found one.

Sorry, I missed the part about keeping it the case (my bad, stupid speed reading  Roll Eyes). A 10.1" screen is 1/4" bigger than the active area, so it should still work fine. The screen I'm trying is wsvga 1024x600 (from looking around, that seems to be the average in 10.1"), and displays with enough detail for my purposes.

Just curious, is there a specific reason you want to keep the whole project inside the wacom case? I only ask because, if you're that worried about getting things exact, you could try doing something similar to the dontiq (where the tablet is left intact).

Please, I just want something that I can draw on right now, this instant, as soon as I can assemble (something most who stalk the board without registering/posting probably feel).

This WILL work, many people have successfully done it. We're just talking about taking a screen, attaching it to a controller and computer, sticking it on top of intuos3, and doodling. Everything else is details.

Unless you're planning to open up the wacom, then you have to worry a little more about the inner workings. Are you trying to keep the whole unit inside the wacom case or are going to make an exterior housing (or use duct tape)?

I couldn't find any good screens in an appropriate size either. 10.0 and 8.9 seem to be mislabeled a lot. Since it's your first cintiq type build, maybe you should worry about the resolution instead of size (since bernard gave you an option if reaching every edge is a big deal). 10.1" screens can be found with pretty good resolutions. The matte are average $20 with shipping more expensive, but you probably don't want glare in your eye when drawing.

I'm building mine for (mostly) the same reasons ~ beside the fact it's fun ^_^

You said the digitizers from a late Fujitsu T1510 or a T900. Did you get both to see which would work better or haven't received the item yet to check?

Forgot to list one "oops" ~ I bought a Sony Vaio PCG-C1X, 8.9" XGA thinking it would work since it was smaller than the working area. I didn't realize the 8.9 wasn't in the same proportions one would expect - exactly 8" (like a glove) by approximately 4.5" (probably a little less). I didn't measure since I was informed by NJYTouch (with a friendly smile) that they couldn't match a controller to the monitor without a datasheet (found a service manual for the computer it was meant for,but no datasheet). Luckily it was on sale ($22 shipped) so it wasn't too painful.

Since this is my first build, I'm not very particular about little things. So I got the specs I wanted in a slightly bigger screen ~ I'm always putting things off the sides of screens anyway. I'm just going to center the screen evenly and keep anything on the screen with a corner or side within the usable area.

Project Name: Black Rabite
Tablet: Intuos3 6x8 $127 (no pen, bought off lease)
Pen: Classic $45
Screen: HSD100IFW1, 10.1" LED WSVGA MATTE Min 5.5 mm Max 5.8 mm $61.49
Data sheet if anyone's interested
http://www.siliconbluetech.com/media/downloads/Hannstar10inchHSD100IFW1-A00.pdf
Controller: LVDS VGA controller board DIY 1024×600 LED LCD screen from NJYTouch $40.98

Total $274.47 (including shipping, tax, etc)

I bought the pieces over several months and it's about the same as if I bought a new intuos 3, so I'm good with the price (though my eye twitched when I estimated the cost before hand ~ it's about average, right?). The price will go up a little if I can get my last addition in, plus the exterior's cost.

Why Black Rabite? It's viciously adorable and can't be taken out by normal means. My 6x8 is both black and strategically cute size-wise (plus another odd association my brain makes).

No modifications necessary so far. Hooked everything up to my lenovo s10-2 (it was the closest and had no problem handling other tablets) for a test run.

First try

Tablet not responding (freak for a second for not immediately testing due to lack of pen). Realize 3 seconds later old graphire software is still installed. Uninstalled software, restarted computer.

Second try

Extended screen to second monitor. Pause for fangirl moment (KYAAAH!!!!!!!!!! **so pretty** XD *ahem* I really like my wallpapers, just happy it was something mild or I'd be embarresed by my reaction). Gently test pens reaction over screen (it seems softer than the one used on my other computers, so was a little paranoid). Reacts fine ~ maybe a little slow but there were other programs running. No noticeable jitter. Pointer displays 1.5" behind placement of pen. Had to run after that, so I didn't try any adjustments.

I'll take some pictures next time everything's connected.

Figure the difference in pen-to-pointer has something to do with the stretching of the computer screen, but if anybody knows how to fix it I'd appreciate it (don't remember reading about that in the forum, but I was focused on the actual build parts rather than fine tuning).

Got a matte screen to use in the outdoors and plan to assemble a battery pack with an exterior outlet (that way I can leave the extension cord intact and plug it into a wall when needed). I first thought of using several 9v for easy recharging and later connecting to a small solar panel (somewhere down the line). Not sure if 9v would be better or  compact laptop/other battery.

I still want to try the wireless vga connection ~ I don't care if the signal is overly compressed (or whatever else people were complaining about with the idea). I just want the option of being able to loosely sketch without being tied to the computer.

I need to look around for a good cover for the screen and an exterior housing. I want to make the whole unit waterproof (ideally shock-resistant/proof as well). My two main ideas for the housing (besides a LOT of electrical tape) are a wide flat plastic tupperware like box with locking sides (will add the gasket myself and holes for cables) and an airtight vinyl bag (thick and durable). With the plastic box I was thinking of using a shock absorbing polymer (like the earthquake proofing sheets) around the controller under the tablet.

While looking around I noticed that many pre-intuos2 (and some users with intuos2) came across the same problem in everyday use (no mods).

It's early here so I can't remember all the reasons (I'll check later) but one major one was nearby interference from other electronics. Netbooks especially seem to drive them mad. Maybe the nearby computer/modem/etc is aggravating it. I didn't  see the model of lcd your pairing the ud with ~ does the problem occur when your just testing the tablet by itself or with the lcd?

Looking through random old posts on some forums (searched UD-1218-r power supply) the supplies were AD-3923FM , output: 12V, 200mA, 2.4VA.

This maybe it

http://www.tablet4u.eu/product/nl/230v-ac-power-adaptor-xdgdud.html

I think the weird adapter was meant to connect to the printer/modem port on older computers (funny, it reminded me of a modem port from the early 90's).

Some posts said that the power supply connected to the serial port (maybe there's something next to or on the cable?)

I think several pens of that generation worked with each other, but not sure (hopefully the pens will be easier to figure out ^_^)
