Need help: repurpose old android screen as secondary touch monitor (wired) - Repurposing Old Devices

I've a galaxy tab 2 7.0 which is beyond repair and hard bricked, I was wondering if I could use it's display and touch as a secondary monitor for windows, with a reasonable response time, for productivity. It would be a tremendous help.

Please read the post before reply. Device is hard bricked. Software solution not applicable. Hardware solution required.

You probably already gave up on this, but I am answering this so other people get at least sortof an answer.
For the display alone you could try to use a display driver board (Just google for "make your own monitor, DIY LCD controller board" Sadly can't post links yet..)
Will be hard as soldering to the connectors of the display is annoying/nearly impossible.
Next would be touch, and there you would also need to find a driver board (designing this yourself is way out of the scope usually) and then calibrate the coordinates. (Probably okay under linux/unix, next to impossible under windows)
Overall cost would probably surpass what you would pay for a cheap, new device which could run a software solution. (which would be more portable and cleaner looking.)
If you are a linux user, you can tether the tablet to your pc, get a vnc server running on it and then stream the feed via ADB over the usb-cable to your tablet. (ADB can connect ports from your tablet to your labtop and vice versa). This means that you dont have to pay anything for an app, and also do custom stuff like just sharing certain parts of the screen to the tablet etc...

Connect Athena to external touch screen monitor, possibile?

Hi guys, i am currently trying to set up my Athena with my car, i wonder if it's possible to connect my Athena with a external touch screen monitor like this one: http://cgi.ebay.co.uk/8-INCH-TOUCH-...9QQihZ005QQcategoryZ32826QQrdZ1QQcmdZViewItem
throw the VGA cable.
I know it will display the screen throw VGA out, but I am not sure whether it will enable the touch screen function, any of you know this?
Thanks a lot
p.s. I will post some screen shot if I succeed in this project.
Is that a PS2 port?
Seems to me the key question is how would it get positioning info back to the ameo? That looks like a PS2 port on the non-vga cable. IF it was sending back mouse positioning info AND a simple ps2 to USB converter would work then I'd guess it MIGHT work with the mouse drivers i've seen discussed elsewhere. There is a fair few conditions to meet but mostly at a low level by the look of things. Not much info to go on and also it loks like they are using a pen of some kind there. That makes it less useful I think?

I am sure you don't need a pen, there are lots of touch screen out there, for example this one: http://cgi.ebay.co.uk/ws/eBayISAPI....tToStoreCat&refwidgettype=cross_promot_widget
I just don't know if we simply plug in the vga cable from our Athena to the touch screen, will that work?
Possibility not, I can kind of see a usb cable there, how about plug that in the usb host ? but then maybe we still need to install the driver.....
Basically, what I am trying to do here to use get a bigger screen to show for Athena in a car. So, I will then have much bigger TOMTOM, and also can watch movie or go on internet.
Any good suggestion guys? Thanks a lot for all your help.
I cant see any specks on that, but i did find another that said it was usb, if thats the case theres no reason why it shouldnt work.

it seems like they all need to install driver, do you think it will work without driver?
thats the only problem, does it need specialist drivers? I havnt been able to come up with an answer yet.
But i wont be buying one for the car, somone nicked me vario yesterday from the car so not even chancing the Ameo.
I was just going to buy a little 7" tv I bought this tiny Keyboard out of Maplin on offer. thought it would look sweet in the car. but this is giving me other ideas, anybody shed light!
They ALL need specialist drivers.
Touchscreen is absolute position, mouse is relative. You NEED the custom driver. It may be possible, but I dont know how.
1. I think on the Pic is a S-Video cable not PS2.
(The specs say nothing about PS2)
2. Till now i just saw Touchscreens with USB and like Profer said they all
need secial drivers.

Thanks for your answer, i just ask one of the seller there on ebay, and the answer I got is I will be able to plug the VGA cable in, that will enable the screen to display, but in order to get the touch screen working, I also need to plug in a USB, so now the question is whether the USB host will work on this....and of course the driver need to work too
The 4in1 cable should allow the USB to connect, but you would have to convince 3m or somebody (make most of the drivers) to write a PPC driver.
As almost ALL ppc's are touchscreen, they probably wouldnt bother for the 1 customer that wants it
If you know a coding guru who understands USB, then get them to do it for you. Either way, I doubt its gonna happen.
IT WORKS!
Hi, everybody.
Don't know how many of u are interested in this issue, but anyway:
1. just grab the generic touch screen driver for win ce 5.0 from the usual site.
2. Copy 'n paste the UsbTouch.dll file into windows root directory of the X7500.
3. Plug the video cable (the one with usb connector).
4. Plug the xenarc TS usb cable in the abovementioned cable.
5. Wait for the dialogue box asking for the driver to be used with the unknown device.
6. Write the name of the .dll file copied into the device.
7. Press ok.
et voilĂ , les jeux sont fait! It woks perfectly, without even the need for calibration.
This is (even if it lacks some of the fun of setting up a carputer from scratch) the ultimate carputer, perfect integration among all application and real time (quite) OS.
Cheers.

Your on the right track with this answer,
Look for a touch screen that has a protocol that is treated as a standard HID ( Human interface device ) Ie:mouse, keyboard etc.etc.
if you can find such a device then the built in drivers for plug and play HID's will work fine.
otherwise the rest are right
Did this really work??? What car? This would simply be quite fantabulous.

USB data input use on a non USB Host smartphone

Hy everyone,
First of all, thanks for this great forum which never fails to impress me.
I have a question which some of you might help answering: I'm wondering if it's possible to use the mini-usb port of my smartphone to get some data input.
Let me explain myself a bit more: I know that smartphones (HTC Touch for me) aren't USB hosts. However, the data connexions are still present.
Here's what I'd like to do: even though the smartphone can't control another peripheral, I'd like that external peripheral to send data to the smartphone, and the smartphone to use that data to control the screen. That would give an alternative way of controlling the screen.
The input would come from another touch surface, so my guess is that using the data to control the screen shouldn't be much of a problem.
So? Any idea if it's possible? What kind of platform/language would be nice to do that? C#?
(I have JAVA development experience, but I'm quite a newbie as far as Win Mobile devs are concerned. I'm willing to learn though
I think I searched this forum (and others) quite extensively before posting. If by any chance I missed a related post, I'd be glad to know about it
No ideas? Anyone?
Last up before I stop...
prob. not
i dont think that is technically possible. i think one has to be the host, and that host provides power. so to power the input device(im thinking keyboard) it would need the smartphone/ppc to be a host....
but i have no clue in this area...maybe someone could prove me wrong?
Hey, thanks for your answer.
The powering issues could be overcomed by cutting the cables and giving power from an external power source (I think several people have tried doing it, I need to find the links again). By the way, the peripheral itself is plugged on 110V, so there's plenty of available power
I'm not seeking here to "control" the device, just to aquire the signal it's sending... Does that seem feasible, or does the peripheral need to be somehow "activated" by a Host before sending anything?
Well, in order to get data, the host must ask the slave each time it needs some. Other things must be done by the host, like usb enumeration. That means there has to be a host or it won't work, unless you use usb on-the-go, but I do not know many devices that support it.

[Q] Does any eInk Nook have hardware that could support a physical keyboard?

Please forgive my ignorance - I'm a fairly new developer and know very little about hardware.
The subject line of the post pretty much says it all. I'm looking for something inexpensive with an eInk screen that I can use to type on, as regular monitors tire out my eyes after a while. If no software exists, I'd be very happy to contribute to that development, which is part of why I was looking to the Nook (I'm most comfortable in Java).
Does the current model or any previous eInk model have the capacity to connect a physical keyboard? If not, are there any other eReaders that do have this ability? (I know I can get an eInk screen for a netbook, but I don't want to spend that much if I can avoid it.) I saw a few old threads discussing whether or not USB Host was possible, but none seemed to have a conclusive answer one way or another.
Thanks for your help!
I'm not quite sure if the current version has Bluetooth. But since it is android and if it does have Bluetooth. Chances are there would be the possibility of connecting a Bluetooth keyboard.
Another possibility is getting an eeepc network and replacing the screen yourself with a pixelqi screen. That should be easier on your eyes (though probably not so easy on your wallet)

Sorry, Volcanolotus, but the STR does not have bluetooth. One further option for that would be use the usb connector, converting it to usb host, and adding the physical keyboard. It is just a concept, but it may work.

Hm. I thought so too. Fret not! I just thought of a solution. It has wifi right... Use this! https://market.android.com/details?...?t=W251bGwsMSwxLDEsImNvbS52b2xvc3l1a2l2YW4iXQ..
Though its really a clumsy solution but a solution nonetheless
Though i love the nook, would not a kindle, already having a keyboard be a better option?
Now, in regards to using the USB port as a USB host, in regards to cell phones running android, the hardware is there, though software uses have been hit/miss on. ICS (Android 4.0) enables usb host functionality natively in the operating system, this will probably be your best bet for the functionality you want. The downside is that I would expect it to be atleast a year or longer before ICS comes to the nook.
keyboard now working
I asked verygreen to work on this and 24 hours later, voila.

[Q] Nexus 10 as a laptop

Hello. I was looking to replace my laptop these days and since i own a desktop pc,i was thinking maybe a tablet would be a solid solution for something more mobile. I own an android smartphone,but i don't know tablets and their limitations. So,to be more specific:
1) Is it possible to read/write data to external devices,like hdd or usb? And if so, does it need root or is it stock enabled?
2)Is it possible to mirror screen to a monitor? I'm reading strange answers about miracast and i am not completely sure if its micro hdmi out enables mirror screening or just movie streaming.
3)You think it is possible to do some programming on it? Obviously i am not talking about serious and heavy stuff, but since it comes with the best processor out on tablets-yet- and 2gb ram and there are many IDE's on play store i'm guessing it should be ok? Also,would it be a near laptop experience if i installed the linux app?
Hope i did't tire you,thanks for reading.
1)https://play.google.com/store/apps/details?id=com.homeysoft.nexususb.importer&hl=en <- non root.
2)HDMI out does complete mirroring iir
3)well, you could boot ubuntu if you HAD to. but i don't see why not.
I don't think Android in general is well suited for a laptop replacement. I need things like the ability to view more than one window at a time, particularly when programming.
That said, one of the first things I want to do is work on being able to dual boot Linux and Android. For most entertainment type things Android is best but for productivity I'd prefer to boot Linux.
Same here. I mainly got the Nexus 10 as a laptop/desktop alternative to connect to external LCD monitor, keyboard, mouse and possibly USB storage. It obviously seems powerful enough.
Questions:
Since the built-in display resolution is 2560x1600 and the HDMI output is 1920x1080 does it scale down the built-in display when mirroring?
In mirroring mode can you use the tablet as a touch input (laying it flat next to the keyboard) in place of mouse?
Thanks.
Thank you all for the fast answers.
1)From what i saw,usb importer is for reading only,not writing. So i'm guessing root is needed?
2)Thanks,i didn't know it mirrored to screen.
3)You are right about that part,programming needs many windows. Im guessing apps that offer ide's with multi tabs and possibly extending the display through the hdmi out to two monitors instead of mirror could be possible,right? How does the tablet do with compiling/running speed?
Obviously you are right though, dual boot would be the best option.
Thanks again.
If you are looking for the desktop experience, laptop is still your best choice, there's plenty of processing power, program compatibility, storage and screen space at ~$500. Tablets are mobile devices with limited HW and OS, but in return significantly faster internet, social media and multimedia access, better screen, longer battery life and much comfortable weight allowing the kind of easy use (e-reading in bed etc.) a laptop cannot. The closest tablets to a real laptop are the full Windows8 ones starting around $1000. If I wanted the programs and stuff I'd go with a $500 laptop, if I wanted the larger mobile, multimedia and reading experience, which I do, I'd get the Nexus 10.

That'll most likely happen on the Nexus 10 as well at some point

[Q] Nexus 7 as display for TV dongle possible?

Hello everyone,
I am attempting to set up a Tronsmart MK908II TV dongle as a portable sandbox and web development environment. For my first attempt I'm using the stock ROM and apps from the app store such as Bit Web Server and Terminal IDE. I've had a fair amount of success, though very tempted to install Pi****u (Ubuntu) for a more powerful environment.
One of my main objectives have a miniature HD monitor so I can have direct access to the device if necessary even when I'm on the go. Before I go out and buy a suitable device for this, I'm trying to get my Nexus 7 to act as the display, since I will always have it with me and it's the perfect size. I believe I may have all the necessary cables and converters to make something like this possible... I'm just a bit stuck at the moment on getting it all to work as I want and I suspect its a software/config/capabilities limitation more than a physical one. I have already attempted this a couple of different ways, including using a USB cable from the dongle and an OTG converter for my Nexus 7, but could not get the Android USB Serial Monitor Lite app to recognize input from the dongle.
Does anyone know of any tools or knowledge that might help me achieve this? I can probably find an app that will allow me to remote control my dongle from my Nexus, which is plan B, but it's far less desirable since there are some circumstances that a purely software solution might not work from the dongle end.
Thank you for your time!
Tennyson Hull
