Title: Nightiq Log
Post by: Night on April 21, 2007, 01:21:09 AM
Ok I begin my Nightiq tonight. I will need some help!

Here: I start with a Lg 15" with internal power supply.. yeah I know.. but this screen was in my old stuff ready to take dust.

Like you can see, I got some jittering because of the internal power supply. Any suggestion?

Your pretty stuck, try using a big bit of metal to shield between the power supply and the screen, see if you get any were. To be honest thou, thats the worst monitor set up for a cinitq Ive ever seen, but youve done alright having what youve got.

i was thinking about making 2 longest cable to connect component to the power supply, and make it external. Its can work, but its lot of work. What you think?


Title: Re: Nightiq Log

Well from your pics, it looks as if your inverter is wrapped up with the main power brick and main controller board right?

Which means your in a bad postion because you cant extend the wires to the backlight bulbs as they will get dimmer.

I cant quite work out how youve managed to get it working in that last pic as I can only see 1 backlight wire?

The ideal thing to do would be to sit down with your main circuit board, and find were the transformed power comes out from and then remove the link, buy a Power Brick (I have one spare) and then hash the power brick wire into the main board. Do you get what I mean?

Also your jittering might not be caused by the main power at all. If you look at my build the jittering was coming from the PCB's around the actual LCD so I shielded them with some foil. Also try disabling left and right click see if it has any effect.

But dont fret, at the worst you can pick up another 15inch monitor for 50quid or less.

i make a test without backlight for put the power supply more far i can, and you right, the problem isnt the power supply.. so I need to shield the left part of the lcd... hope i can be lucky...



Title: Re: Nightiq Log
Post by: Night on April 21, 2007, 11:01:57 PM
no luck, i try to shield it with paper foil, but same problem...

if you were to use LED lighting you could move the power supply more easily perhaps.

When shielding don't forget to ground the shield.

This thing about not extending the backlight cables.  Why is that then, what is it that causes the effect or is it just an urban myth? If you used high tension cables (like car spark plug cables for instance,) would that work?

what you mean to ground the shield? i need to ground the paper foil?


Title: Re: Nightiq Log
Post by: Chems on April 22, 2007, 08:27:56 PM
You need to use proper Aluminum foil and ground that. Im not sure if your just using some paper type stuff as an insulator.

Well drew the extending the cables to the lights, Ive read that elsewere as well as you telling me it at the start of the build. It makes sense really but it would be worth a try to just see what happens.


Title: Re: Nightiq Log
Post by: Drewid on April 22, 2007, 10:24:38 PM
Yeah, or if it's paper on one side and foil on the other side then ground the foil side.




Title: Re: Nightiq Log
Post by: Night on April 23, 2007, 01:06:35 AM
I try the grounding option and isnt work, so I try a stupid idea... what if i take all the stuff and move it up on the tablet?

tadaaaaa is work 100%

(http://jeanfrancoisgiguere.com/nightiq/DSCF1226.jpg)

Im very happy, i think the interference is with the circuit on wacom bottom.

But.. yeah its work.. but now with the lcd circuit higher, its exceed about 2inches.. so i need to found a solution, or create a new case.. :(


Title: Re: Nightiq Log
Post by: Switz on April 23, 2007, 02:29:42 AM
cut open the bottom of the case


Title: Re: Nightiq Log
Post by: Night on April 23, 2007, 03:27:09 AM
yeah but its can be annoying.. no? I didnt have choice to cover it anyway, if i cut the case for let the circuit go outside of the case, its can be dangerous for broke it

by the way sorry for my english lol


Title: Re: Nightiq Log
Post by: Switz on April 23, 2007, 12:30:45 PM
no, you still cover it lol


Title: Re: Nightiq Log
Post by: Chems on April 23, 2007, 12:37:31 PM
Yeah placing it outside the case is a good idea, you can easily make a little extra case to cover the bits sticking out.

Good work on getting it workin!


Title: Re: Nightiq Log
Post by: Night on April 23, 2007, 06:10:31 PM
thanks for your help!! :)

by the way, what is the utility of the thing on the back of the tablet?

this one: (http://jeanfrancoisgiguere.com/nightiq/DSCF1216.JPG)

(the large thing, not the circuit) I think its an isolant..
can I remove it?


Title: Re: Nightiq Log
Post by: Drewid on April 23, 2007, 08:27:34 PM
It's a shield of some kind for sure,   it gets grounded via some springs on the interface board,   and no I wouldn't remove it if I were you.




Title: Re: Nightiq Log
Post by: Switz on April 24, 2007, 12:17:45 AM
no, I think it grounds the board

the copperish thing right?


Title: Re: Nightiq Log
Post by: Chems on April 24, 2007, 11:08:03 AM
Defaintly some sort of sheidling as the Intuos3 has one as well that is attached to the plastic casing by a thick bit of copper tape. I think its why you can place your tablet on top of other electrical items with out getting any jitters.


Title: Re: Nightiq Log
Post by: Night on April 27, 2007, 03:30:44 AM
here what i want to do now.

Ive thinking about use my lcd back frame to hold the power supply, and cover it with the plastic of the lcd:

(http://jeanfrancoisgiguere.com/nightiq/DSCF1239.JPG)

the only problem its the cable.. its too short, so i need to make it longer.

(http://jeanfrancoisgiguere.com/nightiq/DSCF1238.JPG)

And after, I need to create a box on top for cover the lcd part

(http://jeanfrancoisgiguere.com/nightiq/DSCF1241.JPG)

And buy something to protect my lcd for draw on.


Title: Re: Nightiq Log
Post by: Night on April 29, 2007, 05:32:24 PM
Got some time today for continu.

Yesterday I buy this:
(http://jeanfrancoisgiguere.com/nightiq/DSCF1242.JPG), a simple frame for put a photo.. but the glass size is 11x14", so i can use it to protect my lcd.... for 1$ lol

Now i need to make the power cord longer

Now this one

(http://jeanfrancoisgiguere.com/nightiq/DSCF1249.JPG)

a little test for see if all is working or if i broke something

Happy happy joy joy. ;D

Awesome so add that to the files guys, extending the Power to the CCFCs directly on the Dell 1501 doesnt effect performance.


Title: Re: Nightiq Log
Post by: Night on April 30, 2007, 12:45:39 AM
mine isnt a dell 1501. Its a Lg flatron


Title: Re: Nightiq Log
Post by: Switz on April 30, 2007, 02:23:10 AM
No,
I think extending the backlight cables wont make a difference, my theory is that the power that runs to the inverter is very little so that is why you have those things to increase power and voltage, but once it is out there, the backlight cables can be as long as they want.

I did the same thing on mine :)


Title: Re: Nightiq Log
Post by: Night on April 30, 2007, 03:04:52 AM
ahh ok hehe, yeah I did i little test before cut the cable and i see its working, so I do it :)

sweet :D sorry i been away for awhile guys been in Italy again sorting out house stuff.

its cool how in such a short time so many new complete builds :D

oh and ps.. i love the way we all use towels as our anti static extremely safe work top thingy.


Title: Re: Nightiq Log
Post by: Night on May 06, 2007, 04:25:30 PM
i start to cut the case for view the lcd. I have a little problem... the case dont close now

Any suggestion?


Title: Re: Nightiq Log
Post by: Switz on May 06, 2007, 05:04:44 PM
Cut a bigger hole and let the hole lcd sit in the hole, then paint the glass black or something where you do not want do see


Title: Re: Nightiq Log
Post by: Night on May 06, 2007, 05:13:24 PM
humm not a bad idea :)
thanks i will take a look


Title: Re: Nightiq Log
Post by: Chems on May 06, 2007, 05:15:15 PM
Slim your backlight slab down. Thats what I did. I taped the CCFCs to the glass and removed the plastic framing and it allowed just enought space.


Title: Re: Nightiq Log
Post by: Switz on May 06, 2007, 05:25:22 PM
Yeah, but this way, you can keep everything in one peice very easily


Title: Re: Nightiq Log
Post by: Drewid on May 06, 2007, 08:34:09 PM
Get longer screws. 
Use a stack of washers, ro a length of plastic tube,  as a spacer between the front and back pieces
Then tape round the edges


Title: Re: Nightiq Log
Post by: Night on June 10, 2007, 10:37:27 PM
DONE

Since the case didnt fit, my father create me a custom case. But I didnt have lots of pics :(

hah thats great! Good job, looks like youve got a perfect build there.
