I've got a GoKart golf trolley and I have a Golf GPS program for my HD2, so firstly I need to find a holder for the phone but the question I have for you chaps is,
As I'm running Android on my HD2 and this eats batteries - can any of you recommend a good portable charger that works for the HD2? I'm thinking one of those battery packs that has a usb connetion - then I just plug in my standard lead......I may look to see if I can wire up a usb socket from the carts battery via a cig lighter type setup.
The reason why I think I need one is that a round of golf can be 4 hours long and I'd need to have the screen set to full brightness and always on so I can easily see the golf program.
any help would be great
cheers
As you're using a cigarette lighter would a generic car charger do?
Sorry to flag this up after so long.
Do you really need to see the program all the time? I use GolfGPS when im playing and have the screen turned off except when im stood over the ball ready to take a shot and need to know the yardage. Turning the screen off when not needed will save you loads of battery. My HD2 easily gets round a course with 50% or so to spare on battery life. I think GPS can be set to run in the background but even if not, it doesnt take more than a few seconds usually to figure out where you are!
As for holders, i dont know if you sorted it but have a look at http://www.pdahut.com/herbert-richter-holders-and-mounts/ , id imagine the bike handlebar one would probably fit onto a golfcart resonably well!
This site also has a good collection of bike mounts that may well be compatible with Golf cart. Holders and Mounts

I have bought this bicycle mount from ebay and wanted to share my overall positive opinion on it. It is quite cheap, 3,77$ including shipping to Taiwan, but well built, durable and functional nevertheless. It truly is designed especially for HD2.
Pros:
*really universal(up to 1 inch), it was easy to mount and dismount,. no hassle.
*Sturdy fixation on the steering bar.
*360 degree swirling ball-head joint, very easy to tilt.
* not covering any important part of the phone.
* the holder is cushioned wherever touches the plastic of Phone to reduce possible wearing. inserts.
Cons:
* Was rather hard to pull the phone off the mount,the battery cover tended to come off too. But i guess it is reasonable, otherwise the phone would snap off on every bump and jump. I just think that there might be another fixation mechanism, that could be both reliable and easy-releasing..
* no instruction or manual on how to mount/use the holder.
* it is even harder to pull the holder out from the fixed part. I imagine there would be cases when one would try to briefly release the phone out of holder (to make a call for instance) and put it back. Well, with current design it is rather hard. Me maybe I am doing something wrong. Or some parts need to work a couple of times back and forth until they get to the necessary usable condition? I will see..
* The plastic phone holder has a hole for camera, but i would rather prefer if it would have another hole for the LED light, to use it as an emergency blinking light in cases my bike light is damaged/dead.
Conclusion: I recommend - very handy accessory for frequent bikers, but more suitable for outdoor "sunny" biking, where one would not need to take the phone out and back frequently.
P.S. If there was a nice and cheap waterproof case (to drive in rain) i would have gone for it, but couldn't find any, so ended up with this

***If this does not belong here I appologize, and feel free to move this if necessary. I just figured the development community is most likely to take this "upgrade" on***
After seeing that someone used Palm's wireless charger on their non-palm phone; I decided to put one on my Droid Incredible.
***This was done to a completely stock Dinc. I did not use any special back, and the stock back gets to stay on (unlike in the other video that I saw)
Wireless Charging the Droid Incredible
**Disclaimer: This will void your warranty, and if you solder something wrong will probably break your phone. With that said I can in no way be held accountable for anything that occurs while performing this “upgrade” to your phone.
>>>>If anyone knows where I can buy that little void sticker that you will see in a picture below, please let me know! If we can get that sticker then our warranty is not voided by doing this.
Supplies:
1.Palm touchstone charger http://www.shopping.hp.com/product/handheld/categories/palm/4/accessories/FB300AA%23AC3
2.Palm touchstone phone back http://www.shopping.hp.com/store/product/product_detail/FB306AA%23AC3?
3.Micro USB cable
4.Soldering Iron (the finer the tip on this the better)
5.Torx T6 screw driver
6.Safe pry tool (or a small flat head screwdriver)
7.Very tiny insulated wires (I just pulled mine out of a USB cable that I cut up)
8.Electrical Tape
9.[Optional] Multimeter to test that you actually made a good connection
How To (Images are of a higher quality (12mp) so I had to stick them in zip files to get them on here):
1.The palm touchstone phone back has a sticker inside of it that encases the wireless charging receiver, so you need to peel this off. Once it is peeled off it will look like this (without the wires soldered onto it):
(Images can be seen in: Palm Receiver.7z)
2.Remove the battery cover and the battery then unscrew the back from your phone (please view a tare down video for details, there are plenty of them on you tube that I used for a reference.)
1.All you need is a torx t6 screwdriver and a safe pry tool, I used a small flat head screwdriver and it worked just fine. Unscrew the 4 screws around the sides and then carefully pry off every place that the battery cover clips on, as they also hold on the red back.
(Images can be seen in: Dinc Inside.7z)
3.Solder on some wires to the USB connector as shown in the below image without soldering onto the pins next to them. This is difficult and takes some time and patience, since these connectors are very small and close (note the polarity in the image, notated in red).
A.Also it is necessary to place a piece of electrical tape over the components right next to the connector (Green box in the image) as they will short out the power and make it impossible to charge your phone if you do not (I found that out the hard way and went back and fixed it).
B.One final note here is that I had to melt down the red phone backing inside to allow the cables to get past the case. See the green rectangle in the image above for where I had to do that. I just used my soldering iron and melted it down, it makes a pretty nice indention for the wires to fit through.
(Images can be seen in: Dinc USB.7z)
4.Now push out the rubber plug in the red phone backing next to the USB cover (this is encircled in Green in the image from step 2).
A.Run the cables that you just solder on through that so that they are sticking through to the battery compartment on your phone.
B.You can also stick on the palm receiver to the inside of your phone cover (note the direction and placement, as this is necessary to close your cover).
3.Note that I placed electrical tape over the wires. This was necessary to keep them from breaking off of the USB connector since the solder points are so small.
(Images can be seen in: Almost Done.7z)
5.Solder on the wires to the palm charger receiver and you are done. Now you just need to carefully place the wires towards the middle of the phone so that you can close the back of your phone entirely (this is another reason why the wires need to be small).
A.Note the polarity of the connection.
B.Also I put a piece of electrical tape over the connections on the palm charger receiver to protect them (not shown in the image).
(Images can be seen in: Wireless Charger.7z)
Here is a video of the end product and how it works:

Its been done with the Evo, but don't know anyone who did it with the Inc.
http://www.goodandevo.net/2010/06/h...rk-with-palm-touchstone-wireless-charger.html
Sounds really nice. Not gonna try it with mine because I'm too scared
Though shouldn't this be in accessories or general?
What are you doing to align the coils? My biggest concern that's kept me from this is the magnets also would mess up the compass sensors readings which I for one actually value.
Wow, you managed to bring me out of my months of silence in posting...
I feel honored that I can get you out of your months of silence
The coil alignment is handled by the magnets inside of the palm touchstone charger itself (the base unit that plugs into the wall). The metal objects that you can see in the "Palm Receiver.7z" file are actually not magnets, but small circular pieces of metal that get pulled towards the charger base when you get them close to each other. So when you have the phone off of the charger, there are no magnets to mess with anything
Also you will notice that there is a piece of metal behind the coil, and that seems to block the inductive signal all together (because I tried to put it on backwards to no avail). Therefore your phone is mostly protected from the inductive transmission.
The only thing that I noticed, is that the touchscreen on the phone is a little weird when it is on the charger, but I see the same side effects when plugging the phone into a "non-htc" charger (before performing this "upgrade"). **I also saw this on my Moto Droid when connecting it to a 1 amp charger, and I have seen this with multiple other touchscreen devices so I think it just has something to do with the frequency of the charger.
Also in case of any concerns: MY PHONE HAS IN NO WAY BEEN DAMAGED BY THIS "UPGRADE"

Yah, it probably should be, and may get moved (which is perfectly fine by me). I put it in here because I am a developer and much more likely to do this, so I figured the development community would be more interested.

I have a rubber case on my Dinc... would I need to remove it for charging?
___________________________________
Yup.... The ones yoe momma told ya about.... Bad Seed Customs!!
I think you will be ok if it is one of those thin (about 1mm thick) rubber cases. Anything thicker than that and you would probably have to install the wireless receiver on the case itself and remove your battery cover all together.
I tested a thin rubber case that I have (no more than 1mm thick I think) that fits a Droid Eris and it charges as long as its flush to the back of my phone.

Wow, this is amazing, very well done. I think this is the first hard mod I've heard of for an Android. I guess gold cards were a sorta gray area.
I've had my Incredible modded to work with a Touchstone since around June of last year. It works great, but I must caution anyone thinking of doing this to be VERY careful. Experience with soldering and a steady hand is a must. One could fairly easily mess up their phone attempting to do this.
Could you do this with a powermat if you wanted to? I have a few laying around I could use.

What I originally meant was pictures. But now that you've added them and I've seen the glory, this mod is really quite impressive and I'm thrilled you shared it with us. But now that I think about it, could this also do USB wirelessly? That would be pretty amazing.

No, the transmission of data wirelessly is achieved through modulated EM waves. This is simple inductance: a changing electric field creates a magnetic field, a changing magnetic field generates an electric field, so a current carrying loop placed near another loop of wire will induce current in the other loop. The receiver in the phone is engineered to "create" the "proper" amount current to charge your battery when combined with the base. In theory yes, but not with this equipment.
How does the phone treat a USB cable being plugged in - will it charge ok, and have your data transfer rates been adversely effected? I wouldn't think so, since you're only touching the power...

I have used the USB charger and data transfer cables without any problems at all. Also I have copied some files off of my phone to my PC since the "upgrade" and did not notice any extended times or anything that would remotely make me think something was wrong.
I did not run a speed test before and after to see if anything slowed down, but as you said we are only touching the power pins, so I highly doubt anything has changed.
To avoid jacking Verygreens thread on usb host support, I am creating this thread for development of the Nook Color Backpack.
What is the Backpack, you ask?
The Backpack will be an open hardware based addon similar in style to the sliders used on Compaq(HP) iPaqs. It will be self contained in that it will carry its own battery source for powering USB peripherals and also a few built in goodies such as a camera module, stereo speakers(possibly amplified), and possibly a GPS module.
This thread is to help others who may want to build a similar device and to accept input from the community on its design. PLEASE, refrain from any flame wars or other similar postings.
Feel free to post with suggestions, comments or even criticism(as long as it is constructive).

Sparkfun.com sells a bunch of stuff that would make for a good prototype:
5V 600mA boost converter and LiIon charger (w/ microusb charging port):

2Ah single LiPo cell:

microUSB plug - right angle breakout:
http://www.sparkfun.com/products/10031
USB A socket:
http://www.sparkfun.com/products/9011
If you were planning to use a hub you'd need a more capable boost converter or go with 2 LiPo cells in series and step-down. For a proof-of-concept I think you can get pretty far with these parts.

Thanks pokey. I'll check into those. As far as the plug, I'm currently looking at buying and modifying a stock cable...to retain stock charging from a high amp source. Externally I think I will be going with a standard female USB A port for power in/stock USB connectivity.
The hub I've chosen so far is a cheapo Targus unpowered. Very easy to mod into what will be required.
Really need to get on a rough draft drawing of the general layout. I work 12 hours a day in construction. Ill try hard to squeeze spare time in for this and pics of the little I have done so far this week.

solar panel, 1.8" hard drive, flash card reader, speakers and 3g card are some things I think might also be cool in something like this.
I am digging this idea. Can't wait to see some progress on this. If the speakers were bt then you could limit the wires some. Space for a 1/8 inch hdd would be nice because you could just use a cf card if you desired. Could really make the nook into a sort of laptop device if done right. Really can't wait to see this. Also check this out. Found it in another thread. May want to add a holder for it into the design somehow. http://www.amazon.com/ProMini-Wireless-Bluetooth-Keyboard-TouchPad/dp/B003ZJEUBI/ref=pd_sim_e_1

It took some googling for me to figure out what you were trying to do, but I see now you want to make a hard case that slides over the back of the NC with some hardware integrated.
My main criticism is that the backpack form factor is really optimized for handheld devices, and the NC is already pushing the practical weight for a handheld device. We're looking at easily another 1lb or more with this hardware, rendering it more of a docking station, at which point an actual docking station with a keyboard makes more sense.
Still, if you do want to design a backpack, consider incorporating stands and grips to make it more ergonomic. For instance, you could have fold-out tripod legs, or a picture-frame style easel, and indentations or possibly even finger loops.
Personally, I would prefer a genuine dock to serve as the 'other half of the laptop,' without requiring that the NC be either permanently attached to all that hardware or removed from its primary case.
to make the hooks that go around the side you could use sugru to mold them. i would think that would work.
I have a few thoughts.
1. I might find time to make this into my obsession for a while, as much as this interests me. My degree is in electronic engineering and I'm a pretty crafty person so perhaps I can be of assistance. I will give it some thought and see if I can contribute. So busy this days with life...
2. One of the things I need to be able to switch from a full laptop is the ability to sit this thing on my lap and work from a keyboard. With all the current cases, they are not supported properly like a hinged laptop display so they have to be on something and propped up. To be able to use some type of hinged holder that is stiff enough to hold the Nook up would be awesome. I have some ideas on how to do this, it could be the finishing touch once it's all working.
3. With the functionality that most people seem to want, I personally don't think size is that big of an issue. Why don't we figure out how to mod one of the existing iPad cases or something of that nature? That would give a slightly larger keyboard and the extra space around where the Nook would attach and/or slide into could hold the additional hardware like speakers and such. IMO, if I can have the size of the Nook and pop it into something like this when I *really* need to work or type a long email, I'm cool with a slightly larger format.
I'm struggling to keep up with some of the latest info regarding USB host & BT support on the Nook and such, but I'll see if I can read up. I'm guessing that once the source for HC is released it all becomes easier and it appears that CM7 is already making a lot of progress.

More power to you, though it sounds like the Asus Transformer is exactly what you want.
Take a look at this:http://www.energizerpowerpacks.com/us/
I have 2 of the XP4001 models, each one is the size of a small usb hard drive. It has two usb ports on it and charges my phone, digital camera, and mp3 player great.
Haven't tried it on the Nook yet...
If I get what you're trying to do, taking apart one of the XP8000 models and going from there might be a good part of the prototype puzzle?
You can find these at office supply stores, more then big box electronics stores.

This looks like a great battery pack. Thanks for the link.
I've been thinking more and reading more on verygreens thread...I'm start to think KISS. Battery pack and USB hub, with one port facing each way(left,right,top,bottom). Then just make a modified camera with the cord eliminated and the plug molded right into its housing. Have opposite ports facing forward and backward at top and bottom to allow for video chat or (very large) camera usage.
Some benifits of this will be more flexibility in hardware, possible use as a simple battery pack for the nook, and MUCH easier designing of the charging/bypass circuits.

I see what you are saying...yeah, if I hold my nook one handed for any length of time...its heavy. As above, I have started thinking about keeping it simple. The hub I have only weighs an ounce or two, once stripped of the housing. The batteries will be the main source of weight/bulk. The charge controller is about dead simple using a picaxe 20x2 chip and very few components. Mostly it will just be a voltage source sensor and switch to transfer to the appropriate power source(battery or USB input).
I guess I haven't ever looked at this as a laptop converter, but rather as a way to complete the picture, by allowing the addition of things like a camera and microphone input that Android was made for.

@ troyy0206....feel free to work on a seperate design as well. This isn't all about what I want...its about designing something that anyone else can duplicate or modify to their needs.

I've been waiting for week to get my materials to make the home made stylus, finally the most important piece arrived. This took hours to get it to work right. It was a lot easier to get a working stylus for an iPod Touch, but after some tinkering, screaming, sweating and fails I got a pretty good working one.

The most important piece, the conductive foam, I got it from ebay. Just search conductive foam, I got a 4" x 4" still have more than half left. I'm thinking that the wire and metal casing are unnecessary, so any pen or pencil casing should do. What I have discovered so far is that the Nook stylus I made requires a large surface, like you see in the video. I wanted it to be really thin at the beginning that's why it didn't work, since the NC screen isn't as responsive as we would all want.
Anyways, the wire I used, I got it from an old coaxial cable (TV cable). Also, I got the idea from this video, which is a lot more instructive than mine...I just wanted to test it in the NC:
http://youtu.be/4YE8rGuLCtU
I think im going to try a sponge before i get conductive foam.
Very nice! Did you tried to slim the tip of conductive foam?
What is the notebook software are you using on the video?

At first I was trying to get the tip to be the thinnest possible, so it would mimic a ball point pen, but apparently the LCD in the NC need a bigger surface to respond to touches. I was able to get a thin version working on an iPod Touch 3G no problem. I'm going to try to make a new following the video that inspired me, I just need a more flexible wire to make it. Anyways, the app I used is called Handrite
I'm not sure why you'd go to the trouble when you can get a stylus for a couple of bucks on Amazon...
Because of curiosity and creativity and inventively spirit?

This experiment cost me less than 2 bucks, since I used everyday materials around the house. The only thing I had to buy was the foam, which I still have more than half left, maybe for making more or using them for other stuff like transporting cpus xD
Edit: Oh and you might find the foam in everyday electronics too, like HDD casings, tv remotes, etc. So you could get a working (proven to work on NC) stylus for free.

it works and it was really easy to make
Yesterday I had my Nook sitting open on my desk, and plugged in my phone.
The cord dragged over the screen of the Nook, and the keyboard happened to be open. Everywhere the cord touched it tapped a letter.
I tried it again with the cord plugged in to AC, but not the phone...and nothing.
Plugged the phone back in, and was able to tap keys again using the cord.
Maybe we could get a battery-operated stylus that just runs power down to the tip .
I'm thinking triple-a battery, small insulated wire down to, then acting as, the tip, and simply return up to the other end of the battery.
No clue if this would be bad for the screen or not, but as long as it's a low level of power, can't see why it would be.
We have some very creative people here who have the skills to not only make something like this happen, but regulate the flow of power through the wire from the battery.
My thought is that since the screen isn't so great for a stylus on the Nook, maybe enhancing the tapping power of the stylus would help.
For anyone who has no clue what they are doing but wants to try anyways, DO NOT use exposed wire, and in any event i'm not responsible for what happens with the use/misuse/abuse of this information.
Any thoughts on this?
ETA:
Maybe a small triple-a flashlight would make a good starting base for this project, a lot of them go real cheap anymore. Just do away with the light itself, and replace it with a wire. You get a switch already built in and all that way.

That was interesting, but I must ask, will a powered stylus perform any better than bought ones or homemade foam ones?
I tried it again with the cord plugged in to AC, but not the phone...and nothing.
Plugged the phone back in, and was able to tap keys again using the cord.

Without the phone, there is no current flow on the cable, and no magnetic field around it, and so, no capacitance distortion.

Yea, this I didn't know until I found out by accident. I had always just assumed there was, but now know that unless something is drawing power it's in a static state.

That is the question that I posed. If no one else is curious enough to find out, i'll get around to this eventually.
I have a handful of pen-light flashlights floating around here, it would be a simple matter to replace the led with a wire and find out.
When I find time to solder one in i'll let you know how it goes. My job is taking up way more time then i'd like in my life at the moment, so who knows when that'll be.

If you replace the LED by a wire, you will get a short-circuit on the batteries, what means that even if it works as a stylus, you will get your batteries hot and discharged very quickly.
Not to say that is dangerous if the batteries get hot!
Another way would be apply the Ohm's Law and calculate a resistor to replace the LED, but I don't know if this idea (a powered stylus) would be an energy efficient circuit...
Hi,
My made-in-china docking station has just arrived, unfortunately its already been broken (quality material of a matchbox :\),
I have plugged in my micro usb into the socket (female micro usb on the dock) and somehow after few tests the female receiver of the dock fell out.. (I guess it wasn't glued strong enough because I haven't use any extra power to push it in)
Any way.. I have opened it up to see whats going on and found this:

The small piece on the left is the female micro usb plugger that was attached to the green board but fell off..
This is a sort of explanation:

And thats the part it self:

Unfortunately I can't glue it back and definately not weld it on since its too tiny and I don't have proper equipment for that..
But I do want to try to fix it because god damn its 1 day old ! totally brand new!
So I was thinking maybe I should simply tear a cable and plug the + - to the red and black wires at the end of that board..
And so, here comes the question for you expert fellers.
First this is the board:
http://img856.imageshack.us/img856/8915/xo1u.jpg
I have a basic knowledge in electricity but its from engineering study and not from real world, so I don't really know how to read this thing..
Perhaps a better intuition than mines will help too..
Is this board necessary? What does it do? and can't it live with out it?
Why they didn't simply plug the + and - straight to the + - pins of the docking points?
Because thats what I am willing to do but I guess that "Ask the experts before you ruin it" is a helpful tip my mom taught me..
Thanks!

its actually soldered, not welded. its not very hard to solder, even tiny parts.
theres still solder on it. you can reflow it with a heat gun... assuming from your post that you have a welder so im guessing you have a heat gun.
just put the part on where its supposed to go, align it, then heat it.
dont get too close and slowly let the heat build, it'll flow at once. try to avoid applying heat to other parts to prevent them from shifting around.
if you are worried theres not enough solder, buy some solder paste and put a little bit on it.
you can check youtube/google for tutorials on reflowing with a heatgun.
if you dont have a heat gun theres other ways but be mindful of the temperatures of the rest of the components, you dont want anything else falling off.
btw, only pins 2 and 3 are necessary, thats power and ground.
Thanks for your reply but I've actually already fixed it,
I didn't soldered (I used Google Translate for that word ) it all,
I simply plugged out the whole board and attatched the two wires to the +- of a usb cable...
It works great.

i think this is not a good idea
you can destroy the phone with this "FIX", if the phone is fully loaded the dock would load further.
In a extremsituation it can flame up
Search for the heatgun and fix it correctly, please

Yeah I'm sorry but thats a full of crap..
first you absolutely cant flame up your phone by over charging it.. (where the hell have you ever heard about it?!)
secondly, the system for disconnect when the battery is full is inside the phone and not on the charger..
There are few circuit things for defending on the charger but not that..
And last, I already done it months ago and it wasn't bad at all.. sometimes it didn't charge to 100% or dropped down immediately.. but overall was fine..
I use now a new charger (also chinese crap), this one has the circuit board, I don't really feel anything different..
It charges good now but nothing extra noticeable...
Hey man, sorry i won't flame.
I mean the dock can lightup if you don't connect it correctly (short circuit)
But it's not my so you can do what you want
Sorry for missunderstanding

To be honest man there isn't enough current running through the USB to do anything nasty to the dock even if it did short circuit. It certainly wouldn't burn and you couldn't shock yourself, worst case scenario, the dock would just stop working.
