Can we get something like this to work with our phones? Maybe even mod the camera software to control it?

He is just getting power from iPhone charging port, it's easy mod.
I think it's easy to make it on HTC too, but not software controlled, just plain light with on/off switch.

can you export power from the usb port or do you have to tap into the battery using 2 tiny wires to an led source. and after the fact, will the battery be strong enough to support the current for the phone and led?

I really want this phone but HTC has held the camera flash back, limiting the usefulness of that 5mp cam. So looking for a solution I found this http://www.phonephlash.com/meet.html. Anyone tried it?

I haven't tried this one, but I know that it will work because I've taken a photo with my Trinity and had a friend fire his flash at the same time and the picture was fine, without the flash it was impossible.
I did a USB cable with 3 Leds connected in one end... if you plug in that to the USB port of the HD with a convertor will light like the Sun.
This is a example with just one led:

It did it with 3 leds but I can't find the web page with the instructions I follow.
Thank you! Great alternative!
in all frankness, i find it quite silly to use a 1000USD device to power an LED....why not using a battery?

Because I must carry with the X7500... so... should I carry a battery too? What for? I'm carrying the PDA plus the cable with the LED... that's all.
The whole thing seems to be a bit embrarasing, there you are using a US$ 1000 handset, with a USB LED hanging from the bottom, for me it'd look like a alien prostate examination tool, The Phlash seems to be a better idea.
pitty there isnt some plug and go little boc with one or thee leds.
but thanks anyway

Hi, im looking at the posibility of installing one of these into the dash of my Jaguar XK8 to use for GPS, media playback, OBD etc. Most of it shound be relatively straightforward looking around the forums.
Sound wise I can link to my head units auxilary input.
GPS looks possible using a bluetooth GPS.
OBD again using a bluetooth device in conjuction with Torque in android.
Possible link up for reversing camera if i use a USB tv tuner maybe?
Power wise i can use a car charger hidden away inside the dash. Question though, will the unit automatically power on if it receives an AC charge in the case where the battery has run flat and the device has turned off beyond being in a suspend mode?
Is pretty much everything controllable on screen? My current plan would leave no access to hard buttons.
USB host - can I connect to a laptop hard drive using a usb to ide adapter? Just thinking for my 100gb media hard disc.
Think that is most of the stuff covered really.

Yes, root your tablet, use any by linux kernel supported device and some development skills and you're ready to go. idk a out-of-the-box solution.

I got my A101 just for development stuff and put the charger in a power strip with a switch. when I turn the power strip on, the A101 just starts up

the only button would be the power button for shutdown or reboot or the volume control. you would have to have a widget or an app for volume control.

yesno, depends on how much power the harddisc draws. but if you like to attach a camera or livetv adapter as well you have to use an powered usb hub anyway
Wow, thanks for your response... looks like it will do anything that i originally wanted really, which is good news!
Im looking at maybe getting a 7 inch archos - what has prompted this is that I just made the move to android from a windows mobile and so far im dead impressed with it. I also previously had a full windows PC in a car that was unfortunately damaged. Im just looking at fitting something into my replacement car and i thought that a full windows PC is less ideal than an android machine.
I still have my old USB GPS device, which I believe has linux drivers - am I right in saying that if it has linux drivers then it may be possible to get it working under android?
For the most part i cant see the lack of hard keys being a problem. Volume up / volume down will be taken care of by my head unit - so i can set and forget the volume (should be able to set it on screen initially yeah?). Reboot can be handled on screen as well - so far I havent experienced android crashing or freezing, but is this something that tends to happen? If so i guess that will be my biggest problem point.
Also - this is a real long shot - does anyone know if the Archos 70 IT's that are brought as 8gb still have internal laptop hard drive connectors - if so i can just drop in an internal hard drive rather than use usb host.
After having a look at units in store I decided to go with the G9 Archos 80. So far im liking it a lot, its speedy, has a full size usb port on the back which allows me to access my laptop hard drive via a USB -> ide adapter and turns on as soon as it gets power - and has working sat nav. 90% of my goals are already met - just needs some soft finessing and installation in car. Just hoping someone roots the thing soon so I can get her to shutdown / reboot via an app.
Jaguar......xD
I noticed that I can not seem to turn the phone on while it is charging. I usually need to pull the usb plug out of the phone, push the power button to turn it on and then plug the usb back in for charging. Is this by design? If so, not quite sure why...
My other android phones never had this issue.
Also, please correct me if am wrong on this one as well. The USB port for Amaze is a standard micro USB. But for some reason usb side (male) of the charger that comes with the phone has a slightly different shape than regular micro USB plugs - so I can not use the same charger with my other devices that have micro USB (e.g. Sony reader, other phones). Yet a standard/traditional micro USB cables can be easily plugged in the Amaze. Again not sure why HTC decided to go with such design.
It almost feels that maybe I am missing on some "bigger picture" that gives a perfect logical explanation to these two observations...

I'm pretty sure the connector is an HDMI connector so you can connect it to a TV etc. But for why it won't start unless you unplug it beats me...maybe you're just not holding it long enough?
Thanks for clarifying about the port being also an HDMI. I totally missed it. Quite frankly, I did not even realise that micro HDMI and micro USB ports could be combined like that in one. This totally explains my second observation.
As far as not turning on while charging, I tried it many times including holding the power button for a few seconds but it does not come on unless I unplug. Normally when you turn it on there is a slight delay between the press and white "HTC" screen coming on. So maybe I am not waiting long enough and press again and it resets the "power on" command. Not sure...
Anyway, thanks for the info.
Mine turns on when I plug it in from an off state. I confirmed it last night right after my battery died.
Also the USB port is a 12pin. You will need a mHL adaptor to get the HDMI capabilities to work. You can check the Accessories Section.
You should look at your phone while its charging, it goes into recovery to charge but the backlight and colors stay off you can only see the text if your in direct sunlight that's why when you push the power button your basically pressing reboot system now (1st option) in clock work mod so in order to not get that while trying to turn it on while its charging well you have to take out the plug and the click the 1st option

Ah ha! That is great info. I will check it out. Thanks for everybody replies.
Also, I believe some ROMs have issues with turning on while charging. I forget which ones or if I am thinking of something totally different.
I just noticed the same thing the last couple times my phone died, just figured it had something to do with the ROM or recovery.

Your recovery has almost everything to do with off charging

Does anyone have experience with this dock:
http://www.amazon.com/Hyperion-Stan...355001050&sr=8-1&keywords=hyperion+dock+one+x
The reviews claim that it does not bring up dock mode, but the most recent review from July says that its possible with a little modification (bolded).
"I have an HTC One X (AT&T version) and wanted a dock to allow me to use the phone as an alarm clock/bedside device.
The design for this charger is actually quite good, but the build quality leaves much to be desired, at least in my opinion. When I plugged in the dock to power and docked the phone, the charging light did not come on, and the phone kept switching between dock mode and normal mode every few seconds. Also the charging (actually power) light never came on. However, the phone charged just fine, and the dock was heavy enough to not have a risk of tipping over, and fit the phone perfectly.
After reading other reviews, I knew that the dock didn't actually put the phone into "dock mode", so I planned on modifying the device from the start and decided not to send it back because of it's flaws. Upon taking the dock apart I saw that it had a circuit board that looks like it was designed for several types of HTC phones, because of the many blank spaces for components. There was a 10k-ohm resistor which I assume was intended either for the LED power indicator, or putting the phone into dock mode (earlier HTC phones used a 10k-ohm resistor to indicate dock mode), but it's hard to tell since it didn't actually connect to anything. While that was concerning, even more so was the fact that the LED was wired to the wrong pad on the circuit board. When I connected it to the right pad, I found the blue LED was extremely bright, too bright for my intended bedside use. I wired a less-intense red LED (because red doesn't affect night vision) to a 100-ohm resistor connected to the +5v on the USB port. Wiring a 47k-ohm resistor between pins 4 and 5 of the USB port was sufficient to tell the phone to go into dock mode.
Overall, if you just want a dock to charge the phone, or want to put in a little soldering to make it into a decent dock, I can recommend this device. Otherwise I would wait until the higher quality docks come to market."

Has this mod been tried by anyone? Will it work on any dock?
Sounds good and logical to me.....try it....I might to if I can get the dock ordered.... Y wouldn't it work?
Sent with my fast aZZ [email protected] Android.....hox+ is waiting rooted for none stock roms
Dock mode
if I look in the settings of my Telus HOX+ it has dock mode listed with choices that pop up when its docked. I do not have a dock to see what it does but do not all HOX+ have a dock setting? I was hoping it was more magnet activated like my Atrix was
OUTDATED, Do not follow this guide, stay tunned through I am about updating it and giving you a ready solution.
Hello XDA beasts and XDA leechers!!
Today I am breaking my leecher's bounds by writing my first unique How-To for Nexus 6P (might work on every device with OTG support and Marshmallow).
This guide is done using USB 2.0 hub and wall charger and a USB 3.0 Type-C adapter I already had.
If you are a electricity engineer please pay attention and help me moving this glitch to the next level!
I am not responsible if you burn your smartphone or home, we're talking about low electricity through I do not think there's a danger.
Okay, things you'll need:
x1 Scissors to cut wires
x1 Electrical tape to insulate the wires you connect
x1 Lighter to remove the plastic from the wires
x1 OTG Cable (Type-C to female USB)
x1 simple USB 2.0 Hub
With simple I mean the following: it just worked with my Chinese cheap non-wall-powered one, I do not know more information how
Click to expand...
Click to collapse
x1 USB male cable
Will be needed for its +/- wires (If you have a charger you are not using, or a USB mouse, take your s)
Click to expand...
Click to collapse
x1 USB 2.0 keyboard or mouse for test
x1 USB Wall Charger with high Amber output
2A will be cool I guess but not sure yet, I am using it with 0.6A wall charger at the moment and I am getting 0.1A on the phone (I can see it using an application named "Ampere", used for things like this, battery related) because a keyboard and a mouse are getting the rest (0.5A i guess)!
Click to expand...
Click to collapse
(Optimal) x1 ON/OFF switcher
see the attachment photo on this topic, you can find one easily on a old toy or something
Click to expand...
Click to collapse
x1 Nexus 6P (your phone)
Here is the guide, if it is unclear what to do, I also give to you a screenshot of the final thing/hack:
(When I am saying connect the wires, I also mean tape the wires, so if you follow step by step the guide, use tape right when you connect)
Start of HowTo
1.1. Cut the "connect-to-otg" USB cable from the hub, you are about to reconnect it so keep that in mind.
1.2. Cut the USB cable and keep the USB male with its wires, we will use ONLY the black and the red (+/-) wires and this cable is going to charge our phone and power the whole hub.
1.3. Revert the step you've done at step 1 by connecting back the wires and also connect on red and black wires the red and black of the USB male cable of step 1.2.
(Almost ready, you now have a "complicated" cable that have 3 endings 2 of them are USB 2.0 and the other one is connected to the USB Hub)
1.4. Connect the black wire to the one side of the ON/OFF switch and the red wire to the other.
End of HowTo
You are ready, here's a example of how to make it work:
2.1. Connect USB of step 1.2. to the wall charger
2.2. Connect the other USB to the phone through OTG cable
2.3. Power ON the ON/OFF switch and turn it OFF
Glitch is done !!!
2.4. Connect a USB Device on the HUB, it should work, if not move to the next step
2.5. Repeat the step 2.3. once.
Keep in mind that your USB Hub still works without plugging it to the wall charger, but if you also want charging you are going to connect to the charger the USB obliviously, and ON-OFF that tricky switch we added.
If you know more about electricity, let us please know if this is safe for our phone, I think the only downside is the overusage of phone's battery, but let us know, is this hack dangerous for the hardware?
Have a nice day,
George.
Here is what you are about to create, a wall charger powered HUB with a switcher that 'touches'/connects the +/-, sounds dangerous right?
It works through!
Does sound a little dangerous, wouldn't it be less so using electrical tape instead?

True hahah, let me edit the topic, that is a must, I also used it but forgot to mention it.
(I am currently using my Nexus 6P as a computer with this mod (mouse, keyboard and "usb soundcard") and the help of a chromecast, battery is still going down even through it is charging, using a USB 2.0 port of my rooter, the metter of Ampere shows 1750mAh (1.75A) ... Searching for a way to set phone's brightness to 0, absolutely zero, to get the advantage of the amoled screen while still keeping the touchscreen).
Have a nice day!
EDIT:
Here is some information for electricians, using the demonstration of this guide, you can also see the first post on this topic for a screenshot.
1. My wall charger: 600mAh, 5V
2. My Nexus 6P gets about 150-200mAh charging power, according to Ampere application for Android.
3. As I can see/guess the USB devices are getting powered by both smartphone and charger, not sure through because of limited knowledge about electricity and simple circuits.
4. This trick is glitching the Android by making it using MTP (Media Transfer Protocol) while charging, so it happens to reveal that it is POSSIBLE to charge and be in host mode, I am not sure through if it is a placebo and in reality the phone is actually charging only when no key is pressed of keyboard or mouse and MTP goes to standby mode, not sure if what I just said exists in MTP.

Worth the bump,
I found a way to tweak the creation of this guide, clearly SPLITTING the charging of the phone and the powering of the usb devices!
Soon I will update the topic making it the best case scenario guide for "USB Host Mode and Charging on Nexus 6P, while casting to a Chromecast".
Also let me inform you that you are about to charge your phone with a simple/classic USB wall charger of 2.0A electricity while having it connected on a chromecast (via wifi) and a DIY self-powered USB HUB. You have a portable pc in your pocket indeed!
(The trick was to create a stand with a case fan (16V) to cool down that heat monster snapdragon 810 and let the phone charge instead of losing energy even while charging.)
More info soon, there are still cool and kinda safe things to do with your "old" device ^_^,
Have a nice day, George.
