e-ink as external display - propably possible, but assistance needed.
 
Greetings,

[ my english isn't best so pelase forgive me any language mistakes.
I hope we'll understand well. ]

I've came to this forum seeking for answer for my question which was ' how to make e-ink a pc display ', and after reading hundreds of topics on a lot of sites net i've propably get my answer at last.

Just look:

http://www.mobileread.com/forums/sho...&highlight=vnc

In this topic there's clearly written how to do it. I'm little suprised that i've succeded in my seeking, because after a lot of ' it's impossible/ get an ipad ' answers i nearly lost my hope.

Now, that tutorial consider device called ' irex iliad ', which i don't have - and which is not produced anymore, but i got pocketbook pro 903 - which is very similar to irex in any way, so i've thought that it'll be rather stupid to sell new pb903 and buy in exchange something which is, well, very similar but used, slower, old and without any warranty.

Just look, here's specs of pocketbook pro 903:

http://en.wikipedia.org/wiki/PocketB...etBook_Pro_902

and here's 'irex illiad':

http://en.wikipedia.org/wiki/ILiad

Like You see - external monitor trick must be possible on pocketbook if it is on irex.

That linux tricks, servers etc which allowing to make irex an pc display could be done because of, if i understood it correctly, a ' sdk ' [software development kit] - which was launched some time ago, which lets programmers experiment with the irex software.

And [!] here is a ' sdk ' for pocketbook pro [all models] series:

http://pocketbook-free.sourceforge.net/en/sdk.shtml

so - only some good will and few hours of skilled linux guy is necessary to enable ' external display ' feature on pocketbook pro, i assume that most of work is already done if trick is running on similar irex iliad.

i've found topics with salvations on how to make a server on such a device, how to set up screen refresh etc -
i'm just no geek, no programmer, and i just can't make an use of them.

i'm pasting them here, maybe there'll be useful in some way:

There's more, i just don't know what can be useful.

I need help of someone who understand all those ' coding ' and can just put it together, make an use of it, make me a tutorial like

step 1) download x
step 2) click y and write z in column xy

etc.


I'm writing here because i don't really know where should i search for such a help.
There's no respond at e-reader forums.


Please, do a good deed hacker,
help me.

Hmmm,

200 reads and no replies.

Maybe you have not considered the fundamental limitations of "e-ink".

To update anything on the display, it has to be set to "clear the page to white".
This is s-l-o-w (try it on any e-ink display, I tried a kindle).

Then the screen has to be re-drawn from the start to mark in the black pixels.
This is also s-l-o-w.

It's OK for an e-book, where a delay of 0.3-0.8 seconds to "turn the page" is acceptable, but that sort of delay to re-draw the mouse cursor as you move it in real-time will mean that the display basically freezes (too many slow, clear everything, redraw everything, events).

It's OK for an e-book, but if you are using your mouse-cursor this is not going to work: basically the screen cannot be re-drawn fast enough for it to be used as a desktop.

e-ink is not (yet) ready for use as a desktop.
