Title: La Fox Tablet build...
Post by: Le_renard on August 09, 2008, 10:22:59 PM
Bonjour !

I'm starting a build log, hoping this project will be a success...
I don't really expect to build something special, technically or esthetically speaking...
I just hope this screen-tablet will work nicely.

The classic combination - just to be sure I will find some help at every stages of the process...
Phase 1
- Dell 1503FP (eBay 60€ including shipping from Germany)
- Intuos 1 12x12 (usb) (eBay 180€ including shipping from the USA)
- Apple Mini-DVI to DVI adapter (Fnac 25€ including shipping)
- 2x FFC Extension cables (40pin / 0.5mm pitch) + PCB Board (diy-beamer 37€ including shipping)
Phase 2
- ??

The "je ne sais quoi de different"
- iMac case (eBay 60€ including shipping)
- Logitech NuLooq (Amazon 50€ including shipping)

Cost so far : 412€

And, by the way...
- Don't know a thing about electronics !
- Using the metric system too... (hi Colinus)
- Freelance graphic designer and musician (in a great band called Sibyl Vane ^^), working on a Mac for graphic stuff, and Windows for musical ones...

Work in progress New pictures on page 3
- Finished the build, then saw my screen turning black...
- ... and realized I had to start again !

Last edit 09/01/2008 12:30pm Pictures of the case + new beginning !

A couple of days ago, I managed to find all I need to start this build on eBay...
I have already received the Intuos 12x12 and tested it... it works great !

A few days later, I finally made my choice and got a Dell 1503FP. The screen is on its way from Germany, but shouldn't be here before a week or so.

As I'm not very tools of any kind, I'm already wondering if I will be able to do this properly... I am a bit worried about the enclosure and how tu put eveything in such a slim box without breaking it all !
so that's where I looked at my iMac and thought that it might be nice to use an empty iMac 17" case as a "shell" for this screen-tablet.

So eBay again and a got a nice 17" iMac G5 case  for 60€ including shipping...


So, this is a quick mock-up of the project...

Any tips or suggestions ?

no Tip, no suggestion, but I'm really looking forward to this project:)
..if it works, I can be sure to build such one too, I had this idea some weeks ago also, but didnt find any broken imacs or so... and I wasnt convinced if it would really fit... :)

So start building soon my friend :)
I'd love to see such build here =)

Greets from Germany;)

Sounds like a good idea to me , if it'll fit it would be a great case.

Post by: Le_renard on August 12, 2008, 04:29:43 PM
Did one of you guys ever included a keyboard or some input devices to control the shortcuts ?
I guess it's quite difficult to work "smoothly" without using the keyboard at all...

Maybe a very slim keyboard :

Or maybe just a simple numpad and some custom "I-can't-live-without" shortcuts ?

Ok... sorry to post so many useless stuff, but I guess I feel like working on this project by doing this...
I finally grab this device ... The Logitech NuLooq...
(http://www.tech2.com/media/images/img_1318_nulooqnavigator_450x360.jpg)
buttons and spinning wheels, etc... pre-configured for Adobe CS pack...
It's available for Windows and Mac OS.
I guess an on-screen keyboard would be useful for naming my layers, for instance.

That looks interesting.  I wonder if I can get the company to get one to try out.

This looks promising, I dunno about a keyboard but I bet you could get one of these to fit, I wonder how much they run for.

I got mine for 50€ including shipping...

By the way, I received the iMac case... This 17" version is just cute... cannot find other words ^^

I opened it up to look inside and see what I will have to remove and found some strange-shaped screws... I have to buy one of this screw-driver before the next step...
I think the sensor will fit, but I may find some problems with the board of the tablet...
I must confess it's smaller than I thought.

Here are some pictures.

The back of the case... The aluminium stand is nice and could be useful - when adjusted a little.

This is "locking" and securing the case. I will have to find a way to keep this function if I want my case to stay close while working !

Nice, actually using iMac casing was part of my brainstorm. But have to drop that idea as I can't find an affordable casing for sale at my place. This is surely another exciting build. Keep it coming!

Awwwww.   

Cuuuuuute.


Title: Re: La Fox Tablet build...
Post by: Le_renard on August 14, 2008, 10:39:20 PM
 ;D Thank you ! May the great old ones help me stuffing it all inside this case !

I just realized my iMac has a mini-dvi output !!!     I need an adaptor, and it's not cheap at all !  >:( 25€ including shipping !)

I'm also thinking ( a little ahead, i know ^^) about the protection I should use for the lcd.  Glass or plexiglass ?
How thick should be this "layer" ?


I opened up the wacom 12x12 to see what was inside and had to face the truth : the iMac case seems to be too small !!!
3 little cms and 1/2 !!

There is still a chance for me to fix this issue : beneath the case is this edge where you can find the captured screws you have to loosen to lift the back of the iMac.
You can find an aluminium plate, with a lot of tiny holes... ( a "grille" ?)

(http://images.macworld.com/images/legacy/2004/10/images/content/imac1.gif)
Do you see what I mean ?

I think I may try to get rid of this "drilled plate" and let the wacom board "pop-out" of the case, giving it those required extra 3cms.

That could work, but I suppose it will look far less clean and nice. I would have to find some kind of protective "grille" like Wei used on the ports side of his build.

Hum... things are already getting too complex for me !  ;D

Post by: Drewid on August 15, 2008, 01:47:52 PM
The cover can be anything that's transparent really.  If it's a plastic then you can use felt nibs to stop it getting scratched.  If it's glass then it would possibly be better to get non-reflective glass.   
It can be got, cut to size, from anywhere that frames pictures.   

2-3mm is probably about the right thickness, though if plastic you could probably go a little thinner.

I received the screen today, and start working on it after lunch.
Following your build logs, it was pretty fast. ( I had to "dremel" the usual screws, by the way )
Then I realized I needed the same FFC extension cables than Drew. I have to order them tomorrow.
I decided to extend the "backlights" cables. I used some wires lying in a corner of the room. Wrapped them with some black insulating tape.
Then I tried to turn this screen on to see if it was still working. And it did...
Except for two "lines" on the screen. I guess I did this ( can you imagine I forgot to test the screen ? )
I will post some pictures tomorrow to show you those lines...

Then I added the 12x12 board, just to see this with my own eyes... ^^
Very promising. A few jitters, and some tweaking needed to configure the "active area" of the tablet (with the Wacom drivers).

As I told in a previous post, the 17" iMac case is too small. I need to cut a part of the front panel to place the screen at the right place, and the aluminium plate I talked about, too.

This way, i think I could get a decent result. I still have to find a way to protect the board that will pop out of the case. I think I will try to bend some pvc or cheap plexi to achieve this...

I also need to find a kind of frame or something to support the screen. I mean, i can't count on the Wacom case cut like in Drew's build for instance.

Well... I think I will try to use this iMac case anyway and do something out of it. When I ruin it, I will use the Wacom case like everybody ! ^^

Some photos tomorrow !

Post by: Le_renard on August 21, 2008, 09:17:55 AM
My simtiq is looking teeribly today ! All wrapped in silver tape, the lcd protected by a half melt pvc, etc...
But, well, everything is now more or less in place. I need the ffc exntesion cables before realling going ahead.

I'm going to buy some new transparent plastic so I can tape the lcd onto it.

By the way, how did you guys manage to do it ? I mean, most of you have taped - in a way or another - the screen itself to the plastic wacom case, that's it ?
Did you place the tape all along the edges of the screen ? I don't really know how to do it...




Title: Re: La Fox Tablet build...
Post by: wei803 on August 21, 2008, 11:05:28 AM
Mine was "sandwich" by the clear case & PCB. Supported by the signal cable, some L shape plastic with double-side tape.


Title: Re: La Fox Tablet build...
Post by: Drewid on August 21, 2008, 01:26:09 PM
In mine the LCD is taped to the lid of the case with electrical tape, right along the edges,  and the plastic cover it just held in place by being the right size.

BTW :
did you order from diy-beamer yet ?

I wrote them a mail but they did not reply yet on it, and that was some weeks ago...

what did your order ?=)


Title: Re: La Fox Tablet build...
Post by: Le_renard on August 21, 2008, 11:38:06 PM
Yes, I did. I ordered (as mentioned in the introduction summary of this topic I think) two FFC extension cables + their pcb board connectors...

Thanks guys for the tips.. I'll try to get some inspiration from you ^^

Et voila... The Wacom tablet is underneath this gorgeous napkin ( you all will notice the man of taste... ).
By the way, can you see that line on the screen ( lower part of the screen ) ? It's not supposed to be there !
I think the screen is wounded ^

I removed this little magnet ( originally used to hold the remote control ) of the front panel.

Here is where stood a drilled white aluminium plate. The Wacom sensor board will unfortunately, have to pop-out of this "window" ( it doesn't fit in the case )

The back of the case. I unscrewed everything and removed the metal plate and the stand holder. ( if kept in place, it would have crushed the various boards )

I put all these boards on a plastic leftover, because I felt I was going to break something sooner or later ! ( Maybe I did and don't know it yet...)

I taped a transparent plastic sheet on the front panel to support the lcd...
I had to enlarge (or melt) with a Dremel a nice part of this panel because the active area of the tablet was not at the right place !
I really didn't want to do that, but had no choice. I will have to hide this mess !

I don't know if it's still working because I don't have the ffc extension cables yet.

Post by: m0x on August 24, 2008, 08:19:04 PM
hey renard... what exactely did you order ?

I just cant find anything on this page... I dont know why... T_T


Title: Re: La Fox Tablet build...
Post by: Le_renard on August 24, 2008, 10:00:41 PM
what exactely did you order ?
- 2x FFC Extension cables (40pin / 0.5mm pitch) + PCB Board (it's a package. here's the link... http://www.diy-beamer.com/EN/store/comersus_viewItem.asp?idProduct=92

That case is going to work really well isn't it.  It's looking smart.
- Thanks Drew ! I think the case could look nice... I just think I may break something sooner or later on this first build. This "dead line" on the lcd worries me. Well, if things go bad on this first build, I would probably try to find another 1503 to replace it and keep the case... learning by mistakes. I'm also thinking about insulation of the various parts and boards. Since all those boards are fixed on this plastic sheet, do you think I need to insulate them in another way ?

ah, just 2 of these... I just looked for "double extensions", but did not found anything... but ok =)
then I will order 2 of these :D


THere are two revisions of the 1503. They use different FFC connectors, so you'll need to know which revision before you order.

Post by: Le_renard on August 24, 2008, 11:16:35 PM
...btw, did you order your LCD screen from "delwi.de" ?
- Yes, I did. The delivery was longer than I expected. It was well packed, but there is this "dead line" on the screen, which was not supposed to be there. Did I do myself or not ? I'll never know since I didn't - how stupid of me - test it before working on the screen.


Title: Re: La Fox Tablet build...
Post by: m0x on August 24, 2008, 11:21:42 PM
mhh...I ordered one of them too

...well...does the warranty crack down if you split it up?

Just send them an email and ask them if thats normal for their screens...

...I dont hope so...

I just spend 29€ on the extension cables + pcb connectors... ^^


Title: Re: La Fox Tablet build...
Post by: m0x on August 24, 2008, 11:33:13 PM
btw... got icq ?:)

I think then I could ask you some questions at the time the monitor arrives and how you get along with yours very quickly :)


...of course otherway 'round also :)

...the tablet is already here...the other parts payed already... =)

Bending plastic
I've been working on the project for an hour or so today, still waiting for the ffc cables extensions.
I wanted to try to bend some plastic sheet in order to make a protection for the wacom board. So I got myself a cheap hot air gun and simply try.
The first try was the one ! It's not very clean or whatever, but well, it will protect it all so that's a good start...

(http://img520.imageshack.us/img520/6678/dscf3792fa8.th.jpg) (http://img520.imageshack.us/my.php?image=dscf3792fa8.jpg)(http://img144.imageshack.us/img144/475/dscf3793wf5.th.jpg) (http://img144.imageshack.us/my.php?image=dscf3793wf5.jpg)
I blocked the pvc sheet (badly cut with a Dremel... don't do that... it only melts... I should have used an electric saw)
I used this table because it has the right size and angle for what I needed

(http://img515.imageshack.us/img515/4245/dscf3795qs1.th.jpg) (http://img515.imageshack.us/my.php?image=dscf3795qs1.jpg)
Then you have to use the hot air gun.
Tips : Use gloves to protect your hands / heat both sides of the sheet to avoid breaking / keep on heating while bending slowly the sheet.

(http://img241.imageshack.us/img241/1953/dscf3798tn8.th.jpg) (http://img241.imageshack.us/my.php?image=dscf3798tn8.jpg)
Here is the result. I'm sure with a little practice and planning, you could do far better than that.

(http://img528.imageshack.us/img528/2530/dscf3796if9.th.jpg) (http://img528.imageshack.us/my.php?image=dscf3796if9.jpg)(http://img296.imageshack.us/img296/9770/dscf3797tf8.th.jpg) (http://img296.imageshack.us/my.php?image=dscf3797tf8.jpg)
This is where it should be placed...


And, by the way, I received the Apple mini dvi to dvi-d and the Logitech Nulooq Controller...
It's a beautiful device, pretty heavy and well designed. ( I took a picture of it lying on a cd, to give you an idea of the actual size )
(http://img504.imageshack.us/img504/8974/dscf3786dq3.th.jpg) (http://img504.imageshack.us/my.php?image=dscf3786dq3.jpg)(http://img207.imageshack.us/img207/1690/dscf3790vd3.th.jpg) (http://img207.imageshack.us/my.php?image=dscf3790vd3.jpg)
The only, but major (to me) problem is that it only "really" works with CS2, not CS3 !!

You can use the device to zoom in/out, move into your picture freely, and set the size of your brush etc... you can also configure 4 hotkeys... so that's a good start, BUT...
Logitech released a now discontinued software called Tooldial for Adobe CS2 only... this software was meant to give you a full access to all the main menus of Photoshop without using the mouse....
Meaning you could work on full screen with no menus for instance... a bit like Artrage interface, but all hardware ! It's really a shame they decided to let this software down.

Good work with the hair-dryer and the edge of the worktop there.  That's worth remembering.


Title: White screen + pen issues.
Post by: Le_renard on August 27, 2008, 10:46:35 PM
Today, I finally received the FFC cable extensions...
I plugged everything as I thought it was meant to be...
I tested it and... NOTHING BUT A WHITE SCREEN !!
Doesn't smell like somethin burnt or anything...

The screen is detected perfectly by my Mac and my laptop pc... I tried DVI and VGA port...
The computers act as if everything was ok, so I guess it must not be that terrible... is it ?
When I turn a computer on, the screen turns on and remains white (the lights are working, that's for sure !). When I switch it off, the Dell 1503 turns off...
The Menu settings of the screen isn't displayed...


Maybe did I mis-plug the ffc cables ?


EDIT :
I just tried inverting the L and R FFC cables, just to see, and as expected, nothing happened... same white screen.
Then I completely unplugged the ffc cables... same result...
I began thinking it might be something else.. so I tried playing with the board on the edges of the screen and that changed something !
Then I re-checked the FFC cables and here it is...
I'm typing using the Dell as a monitor right now.

New problem : the tablet doesn't react at all ! Damned... what have I done again ?!




Title: Re: La Fox Tablet build...
Post by: Drewid on August 28, 2008, 08:18:32 PM
It might be something as simple as the drivers, I had a problem where the drivers would just stop working on my laptop if I turned things off and on in the wrong order.

The next thing to look at would be all the tablet cabling, reseating all of them.

Otherwise (last resort) it might be a short circuit or something, check to see if anything looks like it might be crossing a couple of tracks.


Title: R.I.P. Dell 1503FP ???
Post by: Le_renard on August 28, 2008, 10:21:28 PM
It wasn't a drivers problem, but a problem of insulation !
I thought I didn't have to use the aluminium plate of the wacom, for an unknown reason... Big mistake.
As soon as I put it back, the tablet was working again.
(http://img363.imageshack.us/img363/4962/dscf3805to5.th.jpg) (http://img363.imageshack.us/my.php?image=dscf3805to5.jpg)

Then I decided to cut the definitive protective sheet. I used a 2mm transparent plastic sheet and cut it to size.
Then I used some tape to protect the screen area of the sheet and painted the rest white to match the iMac case.
Let it dry for a couple of hours.
Then I tried to glue it with some supposed hyper-strong glue called "Ni clou, ni vis" (No nails & no screws). It wasn't strong enough.
So I drilled holes in each corner of the case (front and back) and of the protective sheet.
I used some nice bolts (I had to extend them with coupling nuts because of the thickness of the case) and everything.

Then I secured the -tiq and here we go... Everything was working nicely. No jitters, nice image (but the "dead line" on the screen).
It was even looking quite good. ( I would have posted some photos, but I'm not in the mood for showing-off right now !)

I spent an hour or so tweaking the drivers to calibrate the pen (in vain I must confess...).

And suddenly... the screen turned black, and a very light steam appeared beneath the plastic sheet.
I unplugged it quickly... too late anyway.
Everything is now black for good. The "back" lights of the screen stay off...

I opened the case to see, but notice nothing except this little "blurry" trace on the protective plastic of this board...
(http://img137.imageshack.us/img137/710/dscf3807tt2.th.jpg) (http://img137.imageshack.us/my.php?image=dscf3807tt2.jpg)

When I plug the monitor, the 3 leds of this board (the "Power" board) are flashing alternatively. Pressing the "Power" button doesn't change anything...

No mysteries, the "Power" board is linked to the "blurry" plastic one. So I guess I toasted it, probably because of over-heating.

I'm a bit lost and disappointed to fail that stupidly !
Do you think the screen is "dead" or do you think I should try to replace the first board (if I'm lucky enough to find a spare part) and see what will happen ?

Hmm that looks likely.  There are a couple of things it could be.   It might be that one of the ccfl lights has failed, this would shut down the inverter board ,    it's a self-protection thing.     It'd be worth looking at the tubes to see if they are discoloured or broken.       The haze on the plastic makes it look like the invertor has failed though.  I may have a spare somewhere, I'll have to have a look in the shed.

well...just let me ask something I already didnt get in the instructions of Drews Build.

How - goddamn it ! - do I get rid of these f*ckin' little screws that are build in the back of the lcd panel, holding the metal-case together ?

All my screwdrivers failed to unscrew these very tiny ones... so let me ask how you all did it ?=)

I had to purchase a couple of good screwdrivers, the cheap ones I had weren't good enough.

Thanks a lot Drew...
I think the inverter has failed... only one fo the two electronic bits seems dead, but well, I don't know...
tell me if you found something in your shed. Otherwise, there are a couple of non working 1503 on eBay that one can purchase as is...

well... I thought that too...but my dads hobby is to repair watches, for which he needs very tiny screwdrivers - but these failed also (!).

But thanks to Mr. Dremel I got them unscrewed also :]

You can find inverter boards for the Dell 1503fp on various websites.
The model is "Samsung SIC251SF".

A shop is selling one for only $13, but they're only shipping to USA !
Maybe can someone living in the USA here order it for me ?

I think I have no choice but buying one to try and see...

Today is the day of the re-build phase !
After a few days of self-loathing and everything, it's time to pick up the pieces and start again.

I have a nice case, a working tablet and an (un)dead screen.
I think I must have gone too fast and forgot to insulate things proprely and secure all the parts "softly". It worked, but only for an hour or so. Now I plan to re-assemble the -tiq more slowly and carefully.

I emptied the case of all the components.
(http://img135.imageshack.us/img135/2933/dscf3911vr4.th.jpg) (http://img135.imageshack.us/my.php?image=dscf3911vr4.jpg) (http://img399.imageshack.us/img399/2861/dscf3912dx2.th.jpg) (http://img399.imageshack.us/my.php?image=dscf3912dx2.jpg) (http://img135.imageshack.us/img135/7339/dscf3915ey2.th.jpg) (http://img135.imageshack.us/my.php?image=dscf3915ey2.jpg)

I took a fresh look at the inside of the case and saw that it needed to be cleaner and smoother than that.
So, I will start by carefully "dremeling" all the plastic bits to eliminate every rough or sharp leftovers.

In the meantime, I'm trying to find an inverter board or another 1503... Can't believe it, but well, let's call it "learning by mistakes".

I have an inverter board.  PM me your address and I'll get it to you.  You can have it for the cost of the postage.

Re: the rebuild.  You have a good "proof of concept" so it's a good base to build something more robust,  That's the best way to think about it.   ;D

Thanks a lot Drew, that's so kind !
I really hope nothing else is broken...

By the way, I realized yesterday, while talking with a friend of mine (the one who helped me building the arcade cab' control panel), that my calibration problem (before the crash i mean...) was probably caused by the tablet sensor board and the screen badly aligned... does it make sense ?

If they are at a slightly different angle it would cause problems yes.

Hey ! Thanks a lot Drew, the screen is working again... back to work !

EDIT : It works but I have to change one of the ccfl backlight.
One of the "tubes" was broken in two... so, just to try, I taped the two parts together, and it works... but well, it's clearly not as good as with a working one !
Does anyone has a link to a website where I could buy a replacement light ?
I checked on the various websites mentioned on the forum but am not quite sure of which model I need for my 1503fp...

After a few tests, I see that I have to find a better way to "stick" the screen really reaaly close to the protective plastic sheet...

You used to be able to get them on ebay. (posting might be a problem though).    It might also be worth looking for laptop repair places. If you are armed with the model number of the panel thay ought to be able to look it up.

Hi again... it's been months since I last posted here, because i had so many things to do..
Well...
I'll post some pictures soon, but i just wanted to tell that I completed my project and must admit the case was a bit too big when used daily, but it workED...
WorkED because I broke it (can you believe this ?!!! I caught my feet on the power supply !)
The case is broken and the lcd display badly damaged...
Too bad because it was working pretty well, even if I think I could solve some little "jitter" problems by insulating it better.
Anyway, it's niice to have a little more time these days to come back to the forum for a while !

... and, by the way, i'm looking for a "ready-made" cintiq or d-i-y-tiq replacement... anyone ?

What do you mean by "too big for daily use"? 

I am quickly scanning your build thread, but I am not sure: is this a portable device?

Tell us about the stuff you disliked or would have liked.

You still had some other accessories attached, how was that going?

Well, the iMac case was really nice but too big since I had to add a plexiglass "extension"...
I guess it would have been far better if I had built a stand for this device.
( It was only the iMac case, not the computer itself...)
and I think the A5 size is definitely enough for me.


Title: Re: La Fox Tablet build...
Post by: bernard on September 16, 2009, 07:55:33 AM
Your A5 "choice" is interesting (that's close to a 4x5 tablet I assume).

We easily go down the road of trying to get the biggest tablet possible - without even thinking that a smaller size might actually do the work just fine (for some people at least) -- (well, if you can fine a matching LCD at low cost of course).

Receiving a 12x18 tablet (22inch) can be quite "intimidating"  :-[ -- where am I going to put such a huge device on my desk?  ???


...et un p'tit bonjour du Québec en passant. ;D

Hi guys / salut les gars...
back from the dead after all this time.
A very very busy life, not enough money to start a new project ( I almost succeed in completing the build, but broke it in the end !!! ). I chose to avoid lurking here for a while to avoid any temptation...
But well, I keep on drawing and like digital painting too, so I guess it's time to reconsider all this !
Best
b.

ps : by the way, what you did with all these "new" builds is amazing !
