Hey guys, I'd appreciate your input on this idea.
I have a G1 that was run over by a car. The screen is, of course, completely broken, but the rest of the hardware works properly (charges, adb, etc.).
I also have an old Asus S5n laptop with an awesomely thin lcd display, but with a fried video card.
I have relatively no experience with laptop or phone internals, so here is my question:
How plausible would it be to build a G1-powered tablet using the provided hardware along with a touch panel kit and perhaps a modified android kernel?
getting the Asus screen to display the output of the G1 phone will be a miracle and if it is done...ur probable half way there.
good luck with that
Soo... the only ways I can think about going about doing this is getting a proper LVDS driver for the laptop display (quite possible but expensive [$200+]) and then getting the video output from the G1. I'm not sure that's possible but I remember seeing someone somewhere doing that... could be wrong (hopefully).
Even if you were able to do all of that, you would be lacking input as the touchscreen wouldn't really be augment-able.
Either way, good luck with your project1

I got my Wing second hand from my father. It was in a car accident at one point and pretty much submerged in mud. Anyways, it was taken to a phone place at one point and they replaced the lcd I think, and then shortly after, the phone magically experiences banding issues in the graphics vertically. obviously the pattern changes to the other direction when i flip it open.
more over, the keyboard doesnt seem to be working 100% either. In fact, most of the keys don't function at all. I have tried pulling the ribbon cables for both and putting them back in, and I can see nothing physically wrong with either cable.
Any further troubleshooting assistance would be greatly appreciated.
P.S. I will get out my camera and collect as much data as I can about it in case that helps.
P.P.S. After I sleep that is. I have been fiddling with the thing all night. BTW, There doesn't happen to be any sort of adapter or something to hook real headphones to a T-Mobile Wing is there? One of its primary functions is as an mp3 player (but its really only a ghetto ghettoblaster at the moment, with only speakerphone) and the headphone/mic combo that came with it for its lame usb port don't have the greatest audio quality compared to what im used to.
Well I finally got some time to take the pictures, and I just have to get them off the camera and then ill post what I have.. (I figured I might as well take it apart while I was at it.)
I've got a simple touch that got stepped on, now Joseph Conrad has an interesting hairdo (can see where the crack is).
I've got ADB installed and working well for my other (various) Android devices, so using that is an option if I can figure out the Nook side.
The light next to the USB port goes on when I plug the Nook in, so there's some logic working in there.
Questions:
Can someone suggest a way to test if the device is good excepting the screen?
Is it worth replacing the screen on this device and if so, where could I find one?
Assuming screen replacement isn't an option, I'm considering random fun projects for this hardware. Anyone got recommendations?
The first random fun project I'm thinking of would be a WiFi repeater, mostly because I need one in the house here. Total awesomeness would be getting DD-WRT working on it
if u expert in adb ... then u can use and install program named "screenshot" and then run it and take print screen from ur nook and pull pic from ur sd card from screenshot directory .... all that via adb
but i dont know how ... it's just a theory ..... but it will make sure that ur device working or not and is it screen Issue or not
thx
That's a good idea, speedman.
You don't actually have to install any software.
The stock "screenshot" works well enough.
Ok, the colors are all screwed up, but still.
Code:

Oh, yes you can buy screens from NST's gutted for parts.
It just that they cost about as much as a used NST.
If it were mine, I'd do some hacking.
I've already got a console UART connector soldered to the board.
I'd see about expanding the key matrix and seeing if I could get some I/O pins going.
JTAG would be fun to play with.
So I had bought three Stratospheres for cheap (bundle auction), hoping that I'd be able to pick up another cheaply with a good screen or bad glass+good LCD. However, beings I've not taken one apart to that extreme I wasn't aware how hard it'd be to separate those pieces At any rate, they all work fine otherwise, I know at least 2 boot to Android since I eventually get the haptic vibration indicating it'd reached the unlock screen. I had also hoped that at the very least the Wiki would've been right about HDMI out, but it's hard to find out what all have full support (the Epic 4G [D700] I got instead for example has it mostly but no one's able to get it working).
New screens cost the same as a working Strat, and seeing as I already bought an Epic after finding that out, I'm wondering what to do with these. I love tinkering, so being able to solder in a Composite, VGA, DVI, HDMI video connector and use it as a self-powered Stick Computer would be seriously awesome.
I'll gladly take hi-res PCB photos, with a DSLR and ample (non reflecting) light, if folks want to help tackle this Hell, for that matter... if you've got the know-how and want give it a try, I will give you one of these Strats to see what you can figure out. These aren't like the Epic as far as PCB goes, either. That Epic is very tiny and a fraction of the phone's size, but these Strats are pretty much the full phone's length and width, so lots to play with lol
Anyways, hope someone knows a thing or two and we can figure a hack out!
Thanks.
EDIT: This just came to me...What about something like these, in conjunction with a ROM (preferably Odin flashable) that has USB Hub support?
http://www.monoprice.com/products/subdepartment.asp?c_id=101&cp_id=10114#1011403
Unfortunately it isn't driverless, BUT it does list Linux support, at least on the VGA model! More than I'd like to spend given the project, but we can call that Plan Y (Plan Z being: buy a new screen lol)
Ez way - how about flashing with some latest ROM and enabling tvout (with help of screenshots from DDMS)
Then you can connect any cheap stuff decoding pal/secam and maybe an otg keyboard/mouse + power chord through hub or straight to the batt slot.
The tryhard way - you could try to exploit screen flex slot. You should find 16/24bit rgb dpi'ish interfrace there + 2 i2c/spi busses and some gpios. Maybe utilising it as 16bit rgb going to sort of converting circuit could leave you with like ~15gpio pins for mostly any kind of stuff u want (spi, i2c, irqs). You need a good breakout for that and gotta consider high frequency layout (as rule of thumb, try to make wires between consecutive ICs as short as possible and equal length)
Capabilities and possibilities are unlimited. Just human's imagination and life is.
Id be careful with usb-dvi converters. Might work. Might not. Check with otg keyboard or smth first.

So TVOut on the does actually Stratosphere work? (with a custom ROM, I mean)
You happen to know where to find such a ROM? I know that XDA doesn't have a Strat subforum I've looked high and low, and can barely find custom ROMs, let alone one that's TVout lol Everything is still Gingerbread based, but I suspect that doesn't matter since the hardware is from that time.
As for the latter, I actually hadn't realized that without a screen, I'd be without a MOUSE haha I was totally focused on it having a slider keyboard and somehow missed I'd still need a mouse Nevertheless, doing it myself would be pretty hard :\ I don't know that much about the finer details of hardware, at least circuits of that complexity. Modding an analog audio circuit with new capacitors or an OpAmp is one thing, but that's straight forward In-Out, Power-Ground lol
That isn't to say I wouldn't attempt it but I'm not sure exactly what would be needed. If it's LVDS, I do have an older 15" laptop screen that'd be cool to hack a Strat to use :cyclops: That's adding a bit more complexity to things though, at least to start with right out of the gate.
Sadly I dont know where to get Strat ROM. But I assumed that its HW is pretty much the same as I9000, except the additional keyboard, so aries kernel with patches might/should/could work. There shouldnt be any major problems in porting it. I would get these crappy Sammy sources for I405 and I9000, diff them and try to apply diff on kernel_samsung_aries repo of CM.
About TVOut - it is matter of one or two gate ICs and a jack sensing onboard, as S5PC110 has built in tvout signal generator. So I would expect HW to support it.
Edit: There should be some tvout handling in original kernel sources if it is supported. Though, knowing Sammy, there might be aswell tvout driver enabled but HW not wired at all to support it.
I am looking at doing a project where you take the LCD from an Android tablet (I have an old SCH-I905); and add an HDMI input to it so it can be used as a monitor. I have no experience with how I would even get started on this; besides the 3+ days of Googling that resulted in nothing. I would very much appreciate if someone from the community had something to offer! From some research, what I could see that would maybe do the trick is using some sort of LCD controller board.
Thank you.
do yo know how to operate LCD controller of your SCH-I905? i think if you just want to use your device as an external monitor that you can use 3rd software to do it.
I am interested to know if you have found a way
I'm interested on projects like this. I want to put a female hdmi to lcd or the board or something like that, to view on tv, ie: watch videos without using screen mirroring (for older lcd tv's), playing games in real time (without cuts), youtube, and many more things. If anyone knows about it, please let me know.
Best regards
Im also looking for the same thing. I actually wanna find a way to make my old phone into a notebook. My old notebook motherboard has broke, so i wanna try to transform my phone into the notebook itself using the hardware that is left. I'm pretty sure i wont make it, but ita worth the shot.
Hello folks,
I guess this is the most appropriate subforum to ask this kind of question.
I'm having a broken screen Samsung Galaxy Note 5. And instead of find a touch screen replacement, I want to just get rid of the screen entirely
and instead connect the board to external monitor via hdmi interface preferrably. I believe the part that connect the touch screen is called "LCD fpc connector", correct me if I'm wrong.
So I guess I need something like an adapter that convert "fpc connector" to "hdmi connector".
The question is, is this hack possible? can the phone board output to hdmi monitor at all?
If yes then how to do it properly.
Please englighten me, I'm a total noob on this
Many thanks!
Hey huannb,
I also wanted this badly enough to stumble upon your post. From the light research i have done so far, it seems like this is a project only for those who have well labeled board diagrams and a deep understanding of LCD driver technologies.
FPC stands for "Flexible PCB Connector" and it's usage is ubiquitous in the small form-factor electronics space. If you are working with a FPC connector, you are probably handling a one-of-a-kind engineered interface. There are some hardware hackers who have achieved great feats such as THIS JAPANESE HARDWARE HACKER who build a driver board to adapt iPad retina displays to HDMI. I haven't stumbled on a write-up depicting and FPC interface to HDMI conversion yet. If you find one, please post it here because i would like to meet the person responsible for making it.
The way i see it, we have two choices from here. Reverse engineer a device and build a snowflake adapter which only works on one device, OR recycle the device and continue to live within the realm of consumer hardware.

Hi,
Thank you very much for your insight, it is super helpful and somewhat deep enough for me .
It does seem to involve quite a lot of hacking and there isn't a universal approach.
For my case, it is not worth the effort anymore, I have found a way to use most android mobiles to external monitor without fixing the screen itself without much complications.
I doubt that I can find anyone competent enough to explore this realm any further .
Thank you so much again for your research. Cheers
