I'm beginning a new project and have most of the implementation process done. Basically the part I need help with involves pulling text from my HTC Touch Pro, and transmitting the text via bluetooth to a digital panel similiar to the one below:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
It can be more fancy, but doesn't have to be. The main goals are that it displays text, can receive the text via bluetooth, and isn't bulky (from front to back, height and width don't matter). Running on batteries is a plus as I'd prefer the project be completely wireless.
I'd much rather it be a self contained unit, but I don't mind doing a little dirty work if it means wiring a bluetooth adapter to the screen. I have no knowledge on how the bluetooth adapter would translate the textual data to the screen though, so I may need help with that too.
Thanks for any and all help!

Have you ever really needed a copy of a document or diagram? Usually the easiest way to do it is to take a quick picture of it with your phone. However, this usually results in poor quality pictures, misaligned text, improper framing etc.
What I propose is an application that corrects these problems like so:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
There are two open source tools that do it (http://unpaper.berlios.de/ and http://scantailor.sourceforge.net/ ). I was wondering if these could be ported to Android?
Did you try any of the other "scan" utilities on the market already available? Did you contact the dev's of those applications and see if they are working on a port or would be interested.
I can't find any scan utilities on Market... Do you have any names?
try Scan2PDF
With the aid of some very fine research by JVDE, I put this together from a handful of parts and a 8x2cm board. Functions from left to right are (skip-volUp-voice-volDwn-prev). Works great with Android Auto!

Looks great! Do you have a schematic for how you laid out all of the resistors and such?

Click to expand...
Click to collapse
The schematics are available at the link I included in my OP. As for the physical layout, I'd have to rip it apart to show it; I'll be the first to admit it ain't all that pretty.
I would have preferred to use a laddered approach, but there just wasn't enough room on the 2x8 board that I used, especially considering the area the switches occupy. Plus I didn't have discreet resistors for each value so had to use a couple in series for a number of them.
Nice work, thanks for sharing!
So I received my OnePlus Cardboard in the mail a few days ago, and it is working great. Use it with my G4, and its really good with it's 538-ppi display. Love the folding feature, the coating, etc. It's an all around good device (Forgiving the squeaking noise it sometimes makes when you press the button on the side). But its blurry to the point it will give you headaches in seconds. I did find a QR code to configure the Cardboard app for the OnePlus One, but nada for anything else. So, I made a custom config with Google's Viewer Profile Generator.

Want something like this
Please let me know how to achieve this.
Have looked in car settings
I know in car settings there are several choices for radar should see the choice for turning on radar and choose the type of radar
Trying to find some surplus ones for use in small laptops. These are Motorola phones.

I thought the image went in the first post but this is a valid link to it on Imgur.
I think the metal bar is the speaker cone and it's mounted on something rubber/plastic that flexes. There could be a voice coil type thing in there or it could be piezo- electric like those annoying little beepers.
Those look like blocked. Are you sure are not fake?
I don't think so. Most cell phones seem to have them, some have tiny holes in them.
I suppose I could try a stethoscope on them, or make something like it with a microphone and headphones. By a weird fluke I have a real medical stethoscope in the other room. Mechanics use them too.
