Some necro for future references.

This has been done with iPad panels, look around Hackaday.
You can wire the eDP screens to full DP. Leave HDMI alone, it's a bastard normie smart TV standard that should die a fiery death. It's essentially identical to one of the DVI cable options. DP is far superior to both.

You need a breakout board with a panel tape connector soldered on it to separate the power pins and the signal pins.
Power pins need a power source that can deliver enough juice to drive the backlight and a power regulator if you want to be able to dim the screen.
Signal pins need to be connected to standard DP cable with matching pin layout. Be wary of path lengths. DP opeates on high frequencies so path lengths are important, otherwise you'll get funny artifacts.

These guys:
https://www.gtcocalcomp.com/

They've been making tablets since 1970's I think. Their tablet's main purpose is digitizing stuff into CAD drawings. Their current version of the tablets, the Drawingboard6 has been around for quite a few years now. They have a dedicated linux driver it seems (https://code.woboq.org/linux/linux/drivers/input/tablet/gtco.c.html but there are others available) and a line of tablets they call "graphic": https://www.gtcocalcomp.com/graphics-tablets

The specs on those things are pretty epic.
They have a wireless pen with a battery. I like that. I've used a Yiynova, and the feel and precision of the pen seems a lot nicer than that of Wacom (but both have sucky drivers).
Calcomp is delivering mission critical tools for the aerospace and oil industry. I... kind of like that (on one side it implies awesomeness, reliability and indestructibility, on the other - lots of cruft under the hood and backwards compatibility. Think Debian Stable).
And they sell enormous tablets that go for $3K on Ebay. By enormous, I mean like 42"x42".

So my question is: did anyone test these in drawing/realtime applications? Stylus sensitivity? Software compatibility? Did anyone test them in Linux?

I might have a short access to one of these during a contract job, so if you guys have some testing methodology/suggestions/bash scripts/whatever, fire away!

Like the title says, need an Intuos 3 pen. Just bought a 9x12 off of eBay, but there's no pen included.
New to the forum, pm offers I guess, or if y'all just post straight into the topics that's cool too.

Okay, my tablet monitor sandwich turned me into a liar  Cheesy

This past sumer is when I last test it. I tried all the screen frequencies back then, had a piece of cardboard behind the lcd inside of it's frame, and paper on the tablet as a sheild. This time around, instead of cardboard I used paper. And now I'm able to draw on a regular peice of glass on top of my monitor. Only problem is, like everybody else, lots of jitter around the edges which makes it completely unusable. I'll try grounding the tcon board to the metal plate of the tablet I guess. Wish me luck!

I have an intous3 12x19 and an AOC2269 just like this build
The only difference is that I'm using regular off the shelf window glass which is approx. 2.4mm

Pretty sure others here have used normal 3mm glass:
http://forum.bongofish.co.uk/index.php?topic=2378.msg20544#msg20544
http://forum.bongofish.co.uk/index.php?topic=2379.msg21097#msg21097
http://forum.bongofish.co.uk/index.php?topic=191.msg3069#msg3069

Now the plastic LCD frame of the AOC monitor is about 7.62 mm in height or .3 of an inch
so with my glass (2.4 + 7.62) that would be about 10mm above the wacom antenna circuit board

I can't seem to find whatever the maximum distance is for the pen tip to the sensor board...but maybe it's 13mm according to this post? I really wish all the info was in one place.  Anywho, does anyone have an idea of where I might be going wrong? i don't want to take the LCD out of it's frame, but I can if that's what's required. Just not sure how to make a frame for the led strip yet..  Undecided Any thoughts on all this?

The outage was due to a database problem, but that ought to be OK now.

The attachments should be back.

The server paths have changed recently, It's probably that. I'll have a look.

Most of the image in the builds forum don't show up and clicking on them gives a 404.
Yesterday I saw that the website was having issues, but it's  back now. Is there a major problem or something?  Shocked
