Registered for paste here complete solution.

I have all major components, just need to find time for finish it.
Quick look at my equipment: all attachment plus not mine video https://www.youtube.com/watch?v=1Dd3-t7vkgU

Can you tell us about the LCD controller board are you using, (who makes it, where did you get it, part number, how did you program it, etc.)?

Cheers!

Part 1 - the screen

After good experience from my Tablet-PC, I started looking for something more powerful for better drawings. Because I not like to play with mechanical part and have limited money, there's only one options: buy a screen from TabletPC and connect it to my computer.
Quick research and I found and buy screen from Fujitsu (yep, same brand) T5010 laptop/tablet. Seller was marked as recycling company and probably sell parts from broken tablets as spare parts instead of utilizing them. But that's very good for me because complete screen was quite cheap. Also seller guarantee me that whole display have few scratches but LCD and digitizer are tested and 100% working.

* IMG_3854.JPG (291.23 KB. 1078x859 - viewed 118 times.)

I also bought used stylus from the same seller.
Costs:
70 PLN for complete screen  Grin
100 PLN for pen  Angry
15 PLN for shipping inside Poland.
Total: 185 PLN ~ 60$ ~ 45€

Lets look inside.

* IMG_3874.JPG (479.1 KB. 1459x1094 - viewed 99 times.)

It's easy to find datasheet for HV133WX1-100 LCD panel. The Wacom digitizer is SU5E-13W01AS-01X that works as ISDv4 serial unit.
Screen comes with assfucking connector, but fortunately I also received complete screen cables. One problem less.

* IMG_3859.JPG (395.05 KB. 1459x1094 - viewed 97 times.)

I also got working USB webcam, broken fingerprint sensor, buttons&LEDs that should working, touch sensor that i can't test and 4 antennas (WiFi, Bluetooth, maybe GSM). Not bad for that price.


* IMG_3917.JPG (422.41 KB. 1080x810 - viewed 117 times.)

It's also easy to disassemble mobo connectors and solder cable's terminals to almost anything. I found strange HDD adapter from broken laptop (note, it's 2mm pitch) and solder wires directly into it. So far do good.


Part 2 - the LVDS converter(s)

Next I tested my screen with two different LVDS boards.

* IMG_3918.JPG (445.56 KB. 1200x900 - viewed 136 times.)

http://www.aliexpress.com/item/1PCS-New-MT6820-GOLD-A7-LVDS-LCD-driver-board-5V-universal-support-8-42-inch/32475958834.html
Simply and cheap VGA -> LVDS translator for about 6$. It can be programmed via jumpers and should works nicely (approved 5 weeks later when second adapter comes).
Unfortunately I made a short circuit and broke it. Fortunately LCD survived this.
Pros:
  • nice, small board
  • energy efficient chip
  • relatively fast response time
  • always can work with native resolution

Cons:
  • analog input only,
  • can upscale image to bigger LCD but cannot downscale HD image to smaller LCD,
  • menu is usable only when board have valid input signal,
  • always comes with chinese menu language (can be changed)

http://www.aliexpress.com/item/VST29-V59-HDTV-driver-board-TV-PC-AV-HDMI-USB-fit-8-9-42-inch-LCD/1305921741.html
Nice and fancy but too complex adapter for about 20$. Firmware can be upgraded via almost any USB stick, just copy specific file, plug and wait few seconds. Each file is set for different output resolution, almost any standard is supported.
These type of adapters contain TSUMv29 (USB only for firmware), TSUMv39 (USB for playing music, photos and firmware) or TSUMv59 (can play movies from USB stick too).
Pros:
  • a lot of video inputs,
  • remote control,
  • audio amplifier,
  • teletext in some versions,
  • can upscale and downscale image, ie. FHD image -> 800x600 screen,
  • can play movies without computer

Cons:
  • chip overheats,
  • software works much slower,
  • does not accept some input resolutions like 1024x600 and have problems with my 1280x800 resolution,
  • cable/antenna tuner does not work in my version,
  • always comes with chinese menu language (can be changed)

https://sites.google.com/site/lcd4hobby/4-lcd-tft-screen-tester
- nice site with manuals for controller boards similar to models that I using.

UPDATE

After about a year  Shocked I found free time to make few small steps forward. First 3D modeling for the case.
I wish to 3D print the case. Full black (or full white) plastic, screwed to the screen and create nice angle for the screen. But after few measurement I finished with few plywood parts screwed together.

Here are my design:

* 2.png (129.32 KB. 1019x467 - viewed 24 times.)

LVDS converter and WaxBee converter will be hidden under the screen and create useful angle.
The case will also have a vertical standing option. This allow me to use just TSUMv59 board as a portable screen for PC, laptop, console, camera or watching movies (USB input and single 10-15V supply).

* 3.png (40.15 KB. 315x651 - viewed 23 times.)

Just need to make decision. Include 12V lithium battery or make portable power bank.

Here are pinout for the digitizer (based on bongofish wiki page).
In facts, You need only 4 cables. Extra pin marked LED change state when digitizer detect pen. Nice gadget but not important.

* IMG_4729.JPG (369.27 KB. 1313x1199 - viewed 28 times.)

Pin 1 is on the middle of the board, pin 14 on the edge. You may see small white numbers 1 and 14 right next to pins.
It's the 'industrial'* digitizer with 3.3V serial interface and ISDv4 protocol.


* IMG_4730.JPG (200.38 KB. 1263x791 - viewed 24 times.)

And it's my test cable, compatible with breakout board. You may see this on first post.
Nothing special, just enough for the first test. I decided to run and test all electronic, then disassembly it and start building from mechanical case.

Part 3a - mechanical things

I have complete screen case.
WaxBee and LVDS converter won't fit here. Thus I add extra space made of plywood.
I chose TSUMv59 (very nice thing) and Pro Micro (cheaper than Teensy and not much harder to use) and made case designed for them.

Two parts of plywood + rubber feet:

* IMG_4702.JPG (403.73 KB. 1526x710 - viewed 17 times.)


Position of both converters:

* IMG_4703.JPG (249.64 KB. 1600x487 - viewed 17 times.)


All extra parts together (wrong angle between plywood parts):

* IMG_4704.JPG (284.84 KB. 1600x581 - viewed 21 times.)


All together:

* IMG_4706.JPG (223.23 KB. 1547x528 - viewed 17 times.)


And display on right angle:

* IMG_4707.JPG (227.34 KB. 1524x637 - viewed 28 times.)

Looks like ready to use.
