So I have a bricked Soft Touch Android HU. The LCD / Buttons and such all work fine. Of course, so does the case. This made me start wondering. Is it possible to take an Android Head Unit, remove the systemboard and components, replace with an ODroid and connect the Headunit's LCD / Touchboard and Soft Touch Buttons to the ODroid some how? The one thing that concerns me is that these components are connected by a serial cable to the system board and the ODroid needs USB for touch and HDMI for display. Is there a way to convert this from the Serial to HDMI / USB for Display and Touch from the Head Unit or are these screens and fascias made propietary to the system they service?
Also I know I would need a mini amp. Would it be possible to use the same wiring harness and connectors at the back of the case to power and transfer audio to the speakers or would something else need to be constructed?
Possible? Yes.
Easy? No. In fact, you will need to manufacture some custom components, and these custom components will be VERY sensitive to things like resistance. In other words, the soldering job will have to be done by machine.

Hiya,
I understand that the USB socket on the X1 is slightly different than that of the Orbit 2...
...so I was very confused to see the following:
http://www.easydevices.co.uk/pp/Son..._3.5MM_STEREO_HANDSFREE_ADAPTER_WITH_MIC.html
Would the above accessory work, or are they selling something without actually knowing whether it would work?
If it DOES work, I'll be able to configure my CK7-W to charge/connect to my X1, which is what I want ultimately.
Hmm, I am almost certain it will not work. Not sure why they advitise it for the X1.
The X1 has a mini-usb charging port, but it does not have the extra tack-on pins that HTC's proprietary Ext-USB ports have. So, data and power can flow through the port, but audio and video can not be accessedd natively from the port.
I've searched the HD2 accessories forum and found some inklings of the question I'm asking, but none that quite hit at the heart of the matter. So, my question is this:
Does the HD2 (TMO US) send line audio out through the micro-USB port? I would assume it does, since the dock HTC sells for the HD2 has a 3.5mm jack in back, and it only plugs into the phone via micro-USB.
And my follow-on question would be, if the HD2 does indeed have line audio in the micro-USB port, does anyone know of an actual splitter accessory that splits out line audio and USB charging? I saw this device at AndroidCentral.com's store (sorry, my new account doesn't allow external links) (htc-3-in-1-usb-adapter/5A18A3571.htm) in another thread. But since it's mini-USB and HTC claims it only works for the phones specified, does that mean a gender changer (Daydeal.com, Product ID 31355) wouldn't work with it? Thanks for any info/experiences you folks have!
No one has any info for me?
I browsed around to see if i found anything on this also but i don't think it's possible since it's not a A/V port of any sort. as far as your second Q: The splitter would only be that; something to add additional port's on the device. ie: Since it's connected thru the Micro-sub and the splitter has a mini(assuming)-usb port, it can therefore be charged, Also add's an extra audio jack. (just examples)
Someone correct me if I'm wrong.
Thanks for the response. It may be that the HD2 by itself may not have line audio or any video out signal tied to the micro-USB port, but just the fact that that splitter exists for earlier HTC phones' mini-USB ports gives me hope that the line audio pin out is there. I mean, I'm not an electronics wiz by any stretch, but I think mini and micro USB only require 2 pins for power, right? And there's at least 4 pins there on a micro port.
The older HTC phones used the mini-USB compatible extUSB interface-where the top portion of the connector did the duty as the USB interface and the bottom portion of the connector was the audio interface. Between everyone hating to have a dongle to the emergence of microUSB as the industry standard put extUSB on the road to extinction.

Thanks for that. Makes sense, since they decided (for some stupid reason) to not add a 3.5 mm headphone jack to those phones. But what doesn't make sense is how they can give these newer phones great hardware, and tout their multimedia capabilities, and yet not add a functionality that Apple has had built in since their first iPhone. That's the main reason I still use it: because I don't want to carry two devices around.
Any workarounds for a voip app and microphone for a rooted book color?
the cool guys that know what they are doing are working on bluetooth, that seems to be the best bet to getting a microphone working with NC, cross your fingers!
what about a wired headset with a built in mic. does the nook have the connections to support this?
I think the two best options right now for voice applications are probably the Bluetooth and the slight possibility that the micro-USB port on the Nook seems to have quite a few extra pins on it, which may have left B&N open to a proprietary connector that would allow for additional device connectivity via the micro-USB port.
I've purchased a number of micro-USB adapters in order to plug various devices into the micro-USB port of the NC, with zero success (keyboards, USB headsets, mice, etc). Clearly that port isn't currently operating in that manner, and I'm sure there's a tech savy person that could drop in and give us a simple answer to why this is.
I was also curious about the headphone port possibly have mic capabilities, and was about to purchase a single post headset to test the theory, but then I took a (very unscientific) look at the headphones jack, and it would appear that there aren't enough ring connectors inside it to support an additional channel. Obviously the guys doing the tear-down would know far more about this than myself.
We'll see what turns up over the coming months.
Found this teardown post with spec list and it says that there is no mic input in the headphone jack. I know I read another teardown post which I cannot find that indicated the same thing. I agree that our best bet may be getting the bluetooth working.

Can you detail what sort of adapters you tried? Have you tried a gender changer (type a-a female-female) on the end of the nook cord attached to a keyboard?
Someone correct me if I am wrong but, in order for the usb to do something other than just charge and connect to the PC from the usb, you would have to activate USB host, which is not turned on in stock. Hence no of the fancy toys will work. There are a lot of funky pins on the connector so it may have to be some funky adapter, assuming you get usb host running. There are a lot of hackery potential, but until that project is completed, the wait for bluetooth continues.
Go Occip! (the guy hacking the bluetooth.)

This is what I've been thinking about. I don't have the ability to figure out how to activate the USB Host function, but I read several posts about how it worked on N1, D1, and Hero.
The thing I want to try is using a micro USB to 3.5mm minijack cable like those that came with the G1. It's the only thing I could think of that could logically be supported by the default system since it was necessary in 1.5 on that device.
I don't think anyone is using VOIP yet, but you may be very interested in this thread:
http://forum.xda-developers.com/showthread.php?t=989637
I'm running the CM7 image via SD card from that thread, and the Bluetooth works, and I can connect to my phone and my headset. Several people can connect to their standalone GPS units. Worth watching.
Anyone know if the micro USB port is even powered?
On a lot of phones, the USB connectors aren't powered by the device (like my HD2), so you have to hack together a proper setup that supplies power.
Hi all,
I bought my first Dremel earlier in the week so I can finally put all my evil hardware modding plans into action! First up is building a Pi into a PAL SNES case to use as a multi-emulator using RetroPie, and had some quick questions for anyone in the know…
1. Ive ordered the GPIO adapter so I can use the original controller board from the console, but will this also enable the original power LED on the SNES to work as its on the same PCB, or so I need to come up with other ideas for that? If the latter, what would you suggest given that the adapter will be using all the GPIO pins?
2. My plan is to mount the internals of an Xbox 360 wireless controller adapter (the kind you get for using a 360 pad on PC/Mac) into the case, so that the SNES reset button will press down onto the controller adapter’s button for pairing pads. I know drivers are available, but will the pi have any problems running the adapter power-wise from its USBs?
3. Given that my GPIOs will be taken up by the controller adapter, any ideas how I could get the SNES on/off switch to function as a power switch for the Pi? Ideally I'd like it to safely halt the system then remove all power when I flick the switch to 'off'.
4. Last one. I’m only going to be emulating 8bit/16bit, possibly some pre-8bit stuff, so nothing too taxing. I have heatsinks on the pi’s CPU and GPU, would a fan be needed also or will the pi be fine being passively cooled?
If anyone’s interested I can upload some photos of where I’m at so far, and I hope to get at least the hardware side of it wrapped up by midweek. Ive even mounted a USB stick into an old cart and am using it in conjunction with the original cart connector and eject bar, and a USB extender to make things a bit more authentic
Hello
I have been talking to superdave about adding a second USB to my sony xav-ax100. I am very capable of taking unit apart and soldering on the new USB cable to the board. But that is about the extent of my knowledge on doing this. I have no programming back ground. So here are my questions:
1: upon adding the second usb to the board is there any programming that would have to be done for this to work? Does a second USB icon just show up on the main screen.
2: also Dave talked about doing the UART while the head unit is open. I have tried to do a little research on what this is, and from what I can tell it is a way to hook up a computer to the Sony head unit. Why would I need to do this? Keeping in mind I have no programming knowledge.
This unit is going in a bike so once I get it set up to be able to use two USB's. And of course the "caution screen disable" mod. I should be done with modding this unit.
My hopes for this Mod are so I can leave my thumb drive hooked up to the (1) USB port, and be able to hook up my phone for the AA feature for maps and spotify on the (2) USB port.
Thanks for any help on this.
Hub works fine on mine for use with a USB stick and Android auto.
