OK, I decided to build this for
1) Having an interactive screen where to park some menus of Manga studio while I draw
2) Make a gift to my niece, if she starts drawing (I could "lend" her the Cabinetiq, of Course, but handling a 100 Euro pen is not the same as handling a 20 Euro).
As it should go as an accessory of the UBiQ, it must be an Intuos2 ( and I already had the XD-0608-u).
I already had a controller for the LP097X02 from a precedent failure (ugh!) , so I just had to find a new panel.
Apparently, some Chinese Android tablets use the same screen as the IPAD 1, but their screens - as used replacements - command far less money; I had mine for 20 Euros, shipping included, in the end.
I tested that the screen works, and the controller works, and a preliminary jitter test is very promising
At 1024 x 768, the jitter is very reduced.
At first I mistakenly set it to 1440x900 ( it can't really do it, but it crops the image and keeps working) and at that resolution the jitter was a lot stronger.
This ties in with a doubt that I have - that the work frequency of the tablets is not really chosen out of arcane motivations, but to keep it nearer to the horizontal scanning frequency of most screens "palatable" for "Cintiqizing" an Intuos... which would make interferences all the more compelling.
The patents for the first Wacoms, for example, used a ~550 Khz frequency, instead of the ~666Khz of most of their successors.
