Is it possible to use N900 with a larger external Touchscreen? Possible idea
 

I was just thinking it would be nice to have a larger screen/dock that I could put on my bedside when I'm charging the N900. So I have an idea, but just trying to verify if its likely possible before spending money on it.

I know that most touch screens monitors out there use USB for the interface which the N900 wont support. But what if you added a Bluetooth adaptor to the USB interface of the touch screen?

I was thinking of using a screen like this:
http://www.xenarc.com/product/700tsv.html

Its native resolution is the same as the N900. It has speakers built-in. I could easily fabricate a dock etc.. Main issue is if a bluetooth adaptor added on to the monitor would work with the N900.

What do you all think?

The operating system on the N900 would have to be configured to use the new screen. Apart from the debate of whether the accelerated graphics would work there is the Bluetooth speed issue and power drain to take into account as well. You then have to sort out drivers for the screen too. Summary: nice idea but don't think it is going to be either possible or worth the effort.

why would there be a power drain? The N900 would be plugged into the charger, and the video out would be plugged into the screen. Does the N900 not use accelerated graphics for its TV Out capabilities? Also that touch screen comes with Linux drivers. Wouldnt it be the same as using an external bluetooth mouse/keyboard. Same as how the PS3 six axis controller is being used?

The idea is excellent! What I would like to see in the future is a big touch screen into which you can dock the N900. But this would be a great first step. I don't see why it could not be made to work. If you can plug the touch screen into USB + TV-out, the only part left to be figured out is getting the touch screen input drivers working with the N900 X server.

The idea is to make something similar to the new Sony Dash Personal internet viewer. Except powered by the N900. Figure if I'm going to have my n900 charging on my nightstand, Might as well be able to access its features easily from a glance.

Here's the link to the sony Dash for reference:

Yo dawg, we heard you like touchscreens, so we put a touchscreen in your touchscreen so you can fingerscroll while you fingerscroll.

(Sorry, I know that was awful, but it was all I could think about after reading this thread.)

What bluetooth adapter will you use?

i have my n900 working with an o2 joggler (openpeak) running ubuntu netbook remix over vnc, works great with the touchscreen controls, just a little to laggy though to be useful but it works.

I have a 700 TSV and thought about this kind of a setup too. Unfortunately xenarc only provides pre-compiled binaries for their X11 display driver, and in i386 only. I'm going to drop them a note and see what they say about pre-compiled arm binaries, or releasing the source.

Kinda like the terminal mode demoed on the n97... would be pretty awesome

Re: Is it possible to use N900 with a larger external Touchscreen? Possible idea
 

xenarc sent me a pdf from eeti.com that has some extremely basic info on parsing the data that comes in from the USB/serial port. Xenarc doesn't do the drivers themselves, they just take what eeti.com gives them apparently:

"Please see attached. That is all we can provide. Or you can contact EETI directly. www.eeti.com and see if they are willing to provide you the
source code.

We use their touch solution, so it's not up to us to release any source
codes."

I'll start looking at the pdf, see how far out of my programming league it is. ;-)

So I went and looked on the EETI site and found a download for Linux Driver for their touch solutions.

I'm interested in a solution for an external touch screen for the N900 as well. I've got a project that could use this functionality.

I would like to get away from a tethered solution though and use a wireless control of some sort. But beggers can't be choosers. Even a tethered solution is a positive.

Allthough, native x server is ofc better solution :)

This interests me also.

I have been thinking of how to implement a larger tablet-sized screen as a car system operating from the N900 to use its maps, music, phone, browser, etc. That would mean that the "car" system would not require its own SIM for internet access, and it begins to make more sense to remote the screen and control from the N900 which has all the personal programs and data you carry around, anyway.

At first the idea seemed to point to using a tablet with WiFi to VNC into the N900, but that would require setting up the N900 as a WiFi hotspot, and if already playing music and possibly using the FM transmitter, that's a lot of power drain even while charging.

So a USB tether from the N900 to a larger dashmount remote touchscreen would seem to make more sense.

It would probably be best if the larger "remote" screen had two pages: one for the remote of the N900 screen, and the other with local functions such as perhaps DVD player, OBD-2 data display, etc.

While I would prefer completely "local hardware" solution in the end, with prepaid 3G and OpenVPN + unionfs, (maybe linuxice or meego IVI) it's possible to make full incar use out of n900 with carman + Bluetooth OBD-II adapter... see http://talk.maemo.org/showthread.php?t=37259

The more I think about it, the more appropriate it seems that there should be methodology to simply & quickly operate your mobile computer from other computers.

I was doing research at a university this weekend, working from a printout of a spreadsheet that had been sent to me. The university had Windows computers that guests could log onto, but of course they had little on them but the original Windows software.

If, by connecting my N900 to the computer via USB, the terminal became a remote interface for the N900, I could have wrapped up all my work then & there using a spreadsheet program on the N900.

Similarly, if in a car, all the maps, music, etc. I need/want will be on my mobile (N900), & there will be no slowdown of learning accommodation for operation if a dash computer was simply a remote VNC-type viewer for my mobile computer.

It would be interesting if something could be devised like the program which some USB flash drives run when you plug them into a computer - they start on the computer a U3 program for file management, device ejection, etc. If, when connecting the N900 via USB to another computer, the N900 could run on that computer a program to operate the N900 VNC-like from the computer, it might be simple & fast.
