tablet size vs monitor size.

[Drewid]

I got this PM from Mr Slippy so I though I'd answer it here as I wasn't very clear in the build notes.


one thing i wasnt sure about....and it was a little unclear after reading your guide...the pad's drawable area, is 12x12, even tho the case is 16x16, however, the monitor is a 15 inch monitor...so how does the draw area match the size descrepancy of the monitor and case match up...do you increase the window of the case to match the total monitor size, or lose the edges of the monitor under the case to match the maximum draw area of the wacom tablet circuitry? does that even make any sence? LOL
Anyway, hope you can illuminate my question:) thnx


RIGHT. (cough) The case on the 12x12 tablet is 16" x 16" , The sensor is pretty much that size as well but the active sensing area is 12" x 12".   There is an area of circuit outside of this which is partly where the chips live and partly (I think) an antenna for communicating with and sensing the pen.

A 15" non-widescreen monitor is 12"x9" the visible area is very slightly less than that. The hole I cut is -just- larger than the visible screen and -just- smaller than the LCD panel   Now then that obviously works out nicely.

Those lovely people at Wacom have given us perfect lines to cut the sides to, moulded into the casing. The next question is where you should mount the screen vertically.  I reckon go as close to the bottom of the case as you can while fitting everything in, and here's why:

The Wacom drivers allow you to section up the pad, and apply the different sections to different areas of windows desktop.  Now of course the biggest chunk of pad will map 1:1 to the LCD, BUT if you have a 3" strip of pad unused at the top you can map that onto your other screen. So you can keep photoshop menus on your main screen, leaving your pad free for just the main toolbar and the drawing.

Does that make sense?

* These numbers are calculated. you should look into the spec of your preferred monitor
**This is a Notebook LCD size
*** I found a lot of 21" wide-screen monitors but they varying between 21" - 21.4"


if i found more specs, i'll extend it with more tablets

Heheh... An Intuos3 12x19" with a 22" widescreen LCD would be awesome! Probably still cheaper than the Cintiq 21UX, too

I've read of someone building one as well. I'll have to see if I can get him to log it here.

A 12 x 19 would be a monster for sure, ha. I reckon the cost would be 800 usd for both the monitor and the tablet the most. I am looking for a refurbished 12 x 19 tablet from Wacom instead of buying in ebay - sorry I just can't dish out a couple of hundred bucks to some guy in the Internet. I saw Wacom selling refurbished stuff I don't see them anymore in their website.

Drewid, any luck in getting the guy building the monster logged in here?
 

[Drewid]

Indeed. he is the mighty Chingwa. but r3d373 is also building a biggie

Thanks for the link!

Edit: How big would a monitor have to be for a 6 x 8 tablet?

[Drewid]

Sorry, I don't get what it is you are asking.

[Clint]

Yeah sorry ><. How big would a monitor have to be for a 6 x 8 or a 18 x 24 tablet?

[Drewid]

6x8 would be 10",  that's getting pretty small.

18X24 would be 30" (not widescreen).  which is colossal.
That might be getting to the size where the backlight would be too thick. I've never seen inside anything that big so I don't know for sure.

A friend of mine just bought a dell 30" which needs a dual-feed video card but runs at something like 2500 x 1440 res.   mmmmmmmmm.

Not portable unless you have arms like King Kong, but potentially a fantastic desktop setup.

If you want to calculate your sizes for your own, use the following formulas:

Width of a TFT with a ratio of 4:3
WIDTH = SCREEN DIAGONAL * 0.8

Height of a TFT with a ratio of 4:3
HEIGHT = SCREEN DIAGONAL * 0.6

Width of a TFT with a ratio of 16:10 (5:4)
WIDTH = SCREEN DIAGONAL * 0.848

Height of a TFT with a ratio of 16:10 (5:4)
HEIGHT = SCREEN DIAGONAL * 0.53

Width of a TFT with a ratio of 16:9
WIDTH = SCREEN DIAGONAL * 0.872

Height of a TFT with a ratio of 16:9
HEIGHT = SCREEN DIAGONAL * 0.49

In case you want to check the maximal TFT size for your current pen board, simply transform the formula: W = D * F <=> W / F = D. Make sure you use the correct ratio!

I have a question.  Can I just cut off any part of the sensing area on the wacom and nothing will happen?  Or am I getting at this wrong?  Also, do you think that the menu on the UD-1212 would be small enough to fit into a CTR with an internal power supply or no matter how big or small, it still will affect it.  Also, how far away does the power supply have to be, for example:

s|-------\
c| menu \
e|          /
e|supply/
n
sorry for bad drawing, lol did it with the keyboard

  No, dont' make a cut in in the sensor circuit board.  There are long circuits running from edge to edge, they can't be broken and still work.
