[Q] Adapters compatibility question (is it safe - will it work/charge?) - Motorola Photon 4G

UPDATE: Posted in wrong thread - re post in accessories section. Not trying to spam. Thank you.
Hey XDA. I recently upgraded my phone to a Motorola Photon 4g.
My problem is this:
The phone has a usb input and micro hdmi input.
I bring my phone with me, almost everywhere; however, because I spent a lot of my time at the gym (24 hr fitness), my battery gets low and I cannot keep the phone on long enough (unless airplane mode) without it dying.
My gym has the Nike + Ipod hookups which are mainly dedicated for charging iphones and ipods and also used for video/audio support.
I was wondering, is there an adapter for a male iphone/ipod to hdmi or micro hdmi which I can use to charge my Photon at the gym (even if I cannot get audio/video? I think I have seen some male pin ipod/ipone pin adapters for regular hdmi, and I figured I could then get a regular hdmi to to micro hdmi adapater to see if that would be an adequate work-around?
I'd love to at the "very least" charge my phone at the gym, but my main concern is compatibility issues and/or if the use of multiple adapters may cause voltage or charge/related issues (e.g.: overheating? or future problems down the line?) A while back, I saw a project for a serial to usb DIY project that may work?: http://www.sparkfun.com/products/8245
Can anyone offer some advice? Last thing I want to do is brick my phone.
Even a bluetooth or wifi male ipod/iphone pinned adaper to my phone might be cool also? Any advice?
Thank you so much.

You can't charge your phone through the micro HDMI port, only through the micro USB port. Now there is no reason why you can't convert an ipod adapter back to USB but I'm not sure if they make anything like that. You'd probably have to build the cable yourself from multiple parts.

Hmm....I could be wrong but thought one would need an MHL port to charge via HDMI.
I can't offer you a solution to the ipod adapter issue. However, instead of spending money and time trying to modify something to work, might just get a portable battery charger. I have the Splash Intense one and it charges my phone fairly quickly and can do it about 3 times before it needs recharged. Plus, I can charge 2 devices at once if I want to. The other nice thing about this is it can be used anywhere and I even tether it to my phone and put both in my pocket. This way my phone is always on me and charges at the same time.
If this is something you are interested in: http://www.energizerpowerpacks.com/us/products/xp4001/ or just search Amazon for different units.
Sorry if this info doesn't help you.

atrix/bionic lapdock compatibility with Amaze 4G?

Anyone tried to fit the Amaze 4G on a lapdock? Can't find any posts via search
Those Lapdocks (eg Atrix Lapdock) go on sale for ~$50, basically a display, keyboard, battery and trackpad.
Below is someone's hack for raspberry pi on the lapdock.... since amaze 4G has HDMI out, only thing to do is to see if we can get the cables to fit properly, and the USB functionality(keyboard+trackpad) to work, and the software
http://www.theverge.com/2012/6/21/3105822/motorola-lapdock-hacked-raspberry-pi-rikomagic
So I did a bit of digging...
The Amaze uses a MHL connector (see wiki) which allows for access to HDMI and USB over one connector. The lapdocks seem to have two connectors to plug into the Motorola phones. It doesn't seem like a big issue to replace the cable from the lapdock with a MHL one that you could probably buy off ebay.
Double check which pin corresponds to which wires on the MHL and also on the USB and HDMI cable from the lapdock, cut the wires, re solder, heat shrink, close the lapdock back up....profit???
That's as far as I can tell regarding connecting the hardware the phone. I'm willing to bet that the HDMI will output directly to the screen fine without any software adjustment. But I'm unsure about the keyboard and trackpad.
Thoughts?
I'd be willing to give this a try if there's interest.

from looking at the raspberry pi and other stuff(laptop/wii connected to the hdmi port), you'll get a "mirrored" display... the keyboard/trackpad depends on the usb connection/driver/OTG Kernel, dunno about that
Youll need
Lapdock: $20-$60 (i'd suggest getting the atrix/bionic versions, not the motorola 500 one)

->I can't get any clear indication that the USB data from phone passes through to the USB connector on the MHL adapter
maybe some HDMI cables/connector (HDMI male from MHL connector to miniHDMI female on the lapdock)
I have a tablet and a netbook too, so don't think I'll be attempting this for now
the 35Whr battery(from googling), people say it can charge your phone a couple of times over(your phone's battery is 4Volts*2AmpHr = 8Whr)
I'll see if I can find a cheap one here in Canada.
It's a rather interesting concept.
It kinda reminds me of this.http://www.ubuntu.com/devices/android
Definitely interested in this, would be cool to have this setup.
Live and Die on this day....
went to a radioshack nearby, they didn't have it..
bascially, i would only get one if its around $20 (since you can charge phone with it, $20 for a large battery is worth it, though not for the laptop form factor)
The only docks I can get my hands on are $50+ from ebay. This idea is such a niche product...I'm trying to think of a time where this could be useful.

commute on a train/bus, could watch video on a larger screen while charging your battery
if we had the software to support it as well (like the ubuntu-phone posted earlier or webtop options), could compose email or edit code on the go...
Isn't that why we have laptops?

if you want to spend more than $200, a laptop
if you want just one device that has everything loaded, and customizable(via the lapdock), maybe a netbook or this lapdock
i guess that's why the Atrix Lapdocks are selling at a discount... the manufacturers couldn't find a good way to advertise this expensive device (MSRP is $300 or so)
it's available for $40 on bensoutlet

We don't have hdmi
I took the dock section apart n tried to plug in my amaze to the built in hdmi but no go with netflix. I'll try something else and report back.

[Q] 11 Pin MHL + USB OTG

Hey there, i have tried gathering information about this subject and it seems all threads always lead to this announcement:
http://www.gottabemobile.com/2012/06/29/galaxy-s-iii-new-mhl-connector-also-enables-usb-on-go/
Short: Samsung have changed to an 11 Pin-out to enable USB OTG and MHL Hdmi out at the same time. I purchased an original HDTV Adapter (EPL-3FHUBEGSTD) which as far as i can reliably count indeed has about 11 connectors inside the USB connector that goes into the phone.
Now, i can get HDMI out just fine, but ONLY when i also connect the MHL adapter to a power source (a PC USB Port will do fine), however i have also read, that the phone is able to power the MHL adapter itself but obviously would not be charged then (no surprises there). This does not work however.
Further, connecting a USB OTG cable to the micro usb port on the MHL adapter does nothing. No notification and no devices connecting. No power either, since the LED on my USB Hub does not light up as it should. Connecting any devices to the hub does nothing to change that situation. If i leave out the MHL adapter and connect the USB OTG cable directly to the phone, everything works perfectly. I have tried this with 2 different OTG cables so they are not the problem.
This is an original genuine HDTV Adapter for our phones, which according to that post should be working fine with USB OTG.
AFAIK, this topic --does-- come up more frequently now as i can find a few more discussions about it, albeit none really helpful:

http://en.wikipedia.org/wiki/Mobile_High-Definition_Link#11-pin_MHL-USB_Connector
http://forum.xda-developers.com/showthread.php?t=1811435
That wiki entry is the most interesting link as it definitely states that using MHL and USB OTG simultaneously is possible and is also the reason why the 5 pin layout was changed to an 11 Pin layout.
Looking forward to reading your replies!
the ability to use MHL and OTG simultaneously would give the S3 so much more purpose. It is powerful enough to replace a desktop computer used only for light stuff like browsing and watching videos, and even simple gaming. If samsung made a dock like the one for the motorola atrix I'm convinced they will broaden their target group. The atrix got everything right with this but is inferior hardware wise. I love the idea of a one device for everything concept. Unfortunately it doesn't rhyme very well with the growth society.
Love the MHL and the OTG is even better only after I got the correct cables as the cables changed on S3 to the S2 version, unlimited space for watching films on my phone is now awesome and even better connecting it to to the TV just need a good dock,
is there perhaps any expert advise on this? According to multiple sources it should work but really doesnt. Did i buy the wrong mhl adapter?
I think they will only both work together when being used with an MHL enabled tv. That way the power comes from the tv and the usb on the adapter can be used for the usb-otg cable.

But if i connected the MHL with the s3. Would sound come out of my phone AND my TV or just my TV. If it justs comes out of my TV, then can i hook up my bluetooth headphones and listen to my video or it would not allow me?
Thanks

Ah ok sorry! Afaik you should be able to choose your headphones as primary audio source in the bluetooth settings. I know I can choose what I want to be output to my bluetooth headset, but I don't own an MHL adapter so I don't know about that. Someone with one should be able to try it, and if they don't own a bluetooth headset/pair of headphones they could try with wired ones and see what happens.

I have recently received an MHL connector (5 pin type) and the samsung 11 to 5 pin adapter for it. I can confirm that if I plug my OTG cable into it, and then into my powered USB hub, I can get the MHL to work just fine, both video and audio. The OTG cable powers it just fine, but does NOT allow me to use other devices attached to the USB hub.
I am still researching. I suspect you need to bring all 11 pins off the phone with a splitter of some sort, or possibly wire data lines through the MHL. Probably not with the 5 pin MHL connector and 11 to 5 pin adapter, but with the full 11 pin MHL adapter. I am not up to that level of hardware hacking. I suspect whoever does it first can sell a BUNCH of them!
Oh, and I have a Moto Lapdock for my Raspberry Pi, and would love to hook my S3 to it too!

[Q] Atrix Lapdock with Bluetooth

I searched the forum and could not find this having been asked, but if it already has been, please feel free to point me in the right direction:
I have a Atrix 4G and lapdock and have been experiencing difficulty with the keyboard/trackpad timing out and becoming unresponsive after a few minutes. I have tried different ROMs (Nottatchtrix, Stock, CM7, CM10 [epinter]) and have purchased the adapter cables to see if the USB connector was not sticking out enough (read about that on another thread). None of that worked. Did RMA with Motorola and they returned it saying it works.
My question is: has anyone attempted to use a USB Bluetooth adapter of some sort to make the Atrix recognize the lapdock as a bluetooth keyboard/mouse.
I was hoping to do this as a solution to my current problem with the lapdock since the HDMI still works.
Not sure why you want to put a BT adapter into the lapdock since the phone already has BT inbuilt. Are you thinking that by putting a BT adapter into the lapdock, you can communicate with the phone separately without the phone actually plugged in? If so, then you are out of luck as the Lapdock is a "dumb device" and will only activate when the phone is plugged in. It does not hold any processing or logic outside of it being a USB hub and basically a KVM (Keyboard/Video/Mouse). It will not support BT adapters being used in the way you think it will.

MHL Cable/Screen Mirroring

Just got it, but would like to watch movies on my TV. I have chromecast but i wanted a wired solution to eliminate any lag.
I know the phone has MHL 3.0, but I have a 5 year old Samsung non-smart TV.
which MHL cables can I use? My only requirement is that the MHL adapter should NOT need power. Basically looking for something like the iPhone HDMI/Lighting adapter, or the Samsung MHL 2.0 cables that didn't require power.
Thanks in advance.
Something like this: http://www.amazon.co.uk/LINDY-MHL-H...e=UTF8&qid=1445628106&sr=8-1&keywords=MHL+3.0
"Additional USB Micro-B female for charging & power"
In my experience, MHL requires power, I don't think the phone pumps out enough to power the HDMI without it. That might not be conceptually correct, but every lead I've ever tried will only work with power connected anyway.

MHL 3.0 do not require external power, the port is there for compatibility with MHL 2.0 & 1.0 phones or if you want to charge the phone while using the adaptor.
This adaptor works fine without external power on my Z5C
Somebody gave me this .
MHL Micro USB to HDMI HD TV Adapter Cable Samsung Galaxy S3 S4 S5 Note 2 Tab 3 (from ebay)
needless to say, it doesn't work with my Z5c, it even says so in the description. Is this because the cable is not MHL 3?
Samsung uses a different number of pins I think.
Also, doesn't the receiving device have to support MHL?

Good to hear MHL 3.0 doesn't require external power but it might be the power output on Z5c usb port is higher. Are you sure it doesn't has any problem because when I'm reading the customer reviews I found that.
"I'm usually a fan of Lindy products and have bought a lot in the past, but this adapter has a critical flaw and I'm appalled that they have decided to sell it anyway. When connected to either my Xperia Z1 or Z5 it creates so much interference with the mobile network signal that it the signal completely cuts out. Meaning I can still share the screen, but not stream any content. A quick look on Google confirmed that the adapter is the cause, and cheap knock-off active MHL adapters often do this."

I haven't used it that much yet, only to display content from the phone's SD card. I'll give it a test tonight, to see if there are any problems with network signal while using the adaptor.
