Hi, sorry if this in the wrong area or the post is badly worded but it is my first so please excuse me.
For my final gcse project for technology we have to build a project,in which there are multiple briefs such as lights and speakers or toys etc. I would like to include the use of NFC into this be it a tag on a dog collar turning on a toy or a phone playing music to a speaker, if possible I'd like some ideas on what to do. I'm familiar with python,batch and html and am good at soldering.
Thanks a lot!all ideas welcome will give thanks etc

I'm a bit late, was looking for a GCSE rant thread, but anyway:
To start off, I beat you, already made one for mine. I presume you had the brief that you can make a keyless door, so this is what I did:
Built a generic door, but on the front it had an LDR connected to a PIC chip and 3 status LEDs. I laser cut a panel to hold my phone (Galaxy nexus) and attached an NFC sticker to the back, so it detected it when I put the phone on it. I then used NFC Task Launcher to write the task to launch my client and start unlocking. It can also be launched manually, as well as password protected
It then used the device's rear LED to flash into the LDR in a pulse that would not be possible to easily replicate with a torch, which the chip picked up, and opened the door.
That, + a good portfolio, got me full marks
Point on my part; you can use this as a design, as long as you change it. If you're unlucky enough to end up with the same examiner I had, you'd end up with a lower originality mark, as I already used the same idea. However, to use this idea outside of a school project, permission would be required

Hi! It's my first post here!
I was wandering if it's possible to build a custom "lapdock" station.
Basically what do i need is:
- screen hdmi capable
- keyboard
- battery
- touchpad
- eventually speakers
Since a lapdock has only this stuff inside.
Here is a scheme i tought about:

}
The only thing i dunno is how to make the usb hub to give power to the atrix and to the other devices! I mean it's ok for the electricity, but i dunno if it's correct for data transfert.
About the software, i think that debian could handle all this (speakers via usb, keyboard etc etc.. )
Any suggestion?
sorry for my bad english lol
Are you thinking a stationary dock? Or a mobile dock? From your schematics I am assuming a stationary dock. Either way it would be a great hackaday project.
Actually i was thinking to a mobile one
The schematics works the same, the only thing I assume would change is the dimension of the single parts!
it wont be cheaper than 200 dollars
Sure, but you can add custom parts as a more capable battery, better screen, plug-off BT keyboard etc..
I have been thinking of doing the same type of thing, but my set-up would be stationary. One thing I did think of for myself would be to have a keyboard with integrated touchpad. In the OP's case, it would be one less piece to deal with and make it much more portable.

the more portable you want to make it, the more expensive it will be. and besides, this phone isnt known to run particularly fast on webtop..
lets say you spend 400 dollars... you can pretty much buy a low end laptop that will run way better. the cost to benefit ratio just doesnt seem worth it. not only that, but in the future when new devices come out you might have to scrap this contraption. we don't even know if future devices will have this functionality yet.
I was wondering if I can get something like this anywhere?:

It's a simple enough concept, why haven't I seem this anywhere and where would I be able to get one?
But I can't get just any attachment, I need one that fits my phone, which is a G2.
My Question: Is there an adjustable version of this? one that will fit onto an phone and can be adjusted to work with most?
I've been wondering this for over a year now.
I don't see why not. It doesn't seem like a difficult or expensive concept by any means.
Just thought of something:
what about a micro-usb camera that can be plugged into the phone and used as a front facing camera? is that even possible on android?
That's an interesting concept.
Do you have a link to this product?

Did you READ the OP, or ANY of the following posts?
We're not even sure if such a product exists...that's what we've been talking about!
Is this a real product or not???
Where did that picture come from???
Or, Is that a nice Photoshop job???
Thanks

And then check the second link on the list!!!
It is a nice PS job!!!
You're welcome
well the idea is great. Looks possible and should be expensive but I think it will require some software which uses the back camera while video call (don't know if it already exists or not though it shouldn't be hard on an andriod). I have not seen this or anything similar for sale as of now.
This sounds like a job for a 3d printing hobbyist!
If people are interested and willing to fund development (can't be more than $30 per prototype print), I would be willing to create a 3d-printable universal version.
I already have a project that is somewhat similar (creating a universal accessory to expand the functionality of your phone) to get an idea of what I am capable of, see it here:
http://forum.xda-developers.com/showthread.php?t=1476571
What I would need from you guys is ideas about what kind of mirrors could be used. They would have to be readily available to nearly everybody and easily fitted into the holder. The plan is likely going to be, you can order the 3d-printed project from a 3d printing service, then either go to your local store or some sort of online store and get the mirrors separately.
that seems like a pretty good idea but then you would have to carry around a fragile mirror.
I recently went out and bought a Kinect for the 360. After playing around with it and working to have it work correctly, I rigged it up on pole for testing and took a picture with the phone because of the redneck-ish way its just sitting up there (too good not to share).
When looking at it (the photo), I noticed that the IR port on the Kinect was glowing in the photo (violet). I've got the photo on my phone, but its too large to directly attach and I've got no access to places like photobucket while at work. I'll have to post it later..
So.. Anyone else have any experience with the Epic4G Camera picking up IR signals?
Can't wait for pics

Here it is.. notice the green "on" light. On the kinect, the left most is the IR source. Glowin purple *shrug*
Yes. Its a PVC pipe. No, there is no base. No, the sensor is not attached in any way. It was oddly secure just sitting up there.

Ahh. I didn't know that! Kind of was weird when I saw the photo, ergo the question. Thanks!

Lots of cameras detect bits of the IR spectrum. Cameras, unlike people see all the electromagnetic energy that hits their sensors. They typically have filters to dampen this effect but I can't remember having a camera that didn't see a little bit of infrared. It is the same with the Wii in my house.
Posting epic posts straight from my Epic 4G.
Its a digital camera thing. Film wouldn't have this issue, but its about the way that the sensors on digital cameras detect light.
That is some trippy isht. Thank you for posting

That PVC kinect stand is nothing to be embarrassed of! Now that border along your ceiling is another story! lol j/k!

I know people have done LEGO stands for almost every phone possible but I thought I'd just share my very simple and minimalistic stand.
It works in both portrait and landscape and has the potential to be made into a dock with the right tools (such as THIS or a POGO pin setup)
Here are all the pieces you need to duplicate my stand:

"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Here are the steps:
Finished product:
The extra length of the pieces extending to the back of the stand are required because in portrait mode, the phone's weight is a bit too much if shorter pieces are used instead, the extra length provides stability. The shorter white piece in the front provides a slightly higher lip to easily put the phone in portrait mode and provides the required stop in landscape.
Thanks for reading, hope you enjoy.
wow, never thought of using legos. Great stand!
This is a good idea to not pay 80€ for the dock XD
Well done!! I might have to run down to Toys R Us today
This is clever...thanks for sharing!
I guess there was an upside to keeping my giant boxes of Lego around.
you can make it taller and incorporate the usb cable to make it a true dock!
I can never find just regular legos to buy LOL. Walmart for example only has the pirate kits and junk. Where do you buy regular legos? I guess I'll check Amazon.

Ahhh too clever! Too bad I don't have any Lego pieces lying around (anymore).
i added a few more to heighten the back of the support. Now it can hold my N7 also

So I recently got myself a 2004 Nissan Maxima.
This is what the centre console looks like stock
Anyways, when I bought the Nexus 7 I placed in front of the screen and it was a perfect fit. I decided to open it all up and move the screen to a lower position. (I lost one of those map pockets but whatever). Sidenote: on the left side of the picture under the steering column I tucked away an Avantree bluetooth module. Helped me retrofit the car with bluetooth audio so no wires
After all that I was left with this:
So i decided to install my N4 qi wireless charger in there. It's pretty ghetto really, I bought some cardboard, some felt and a pvc pipe for support taped it all together and:
Gave it power by soldering a micro usb cable down the back. Placed it in the huge space while resting the end of the pvc pipe onto an inner lip:
Best part is, my N4 fits nicely as well and because of the rubber lip I created to help the N7 slide in, it isn't free to move around.
When I took these pictures the soldering wasn't done which is why they aren't charging in the photos.
Anyways, thought I'd share, hope you guys liked it! Also sorry if this was more of a mod than an accessory but still
Let me know what you guys think!
I think its awesome!
Question though, how are you running Navigation with the Nexus 7? Are you tethering your phone to it? Or is it LTE?
There are lots of offline gps apps (navigon, sygic,...). And you can update the maps over wifi since the n7 is removable from his build carboard. No traffic informations I guess, but that's fine with me.
Very nice though. I wanted to do a thing like that but there are too many modifications to do on my '96 Peugeot 106^^
Maybe with a new car in a few years.
On my 2.3 device I had a "car interface", it's helpful for quick interactions. You might wanna look it up
