[Q] hacking docks to provide audio, hdmi or sync (MHL and stuff)
I've spent some time searching looking for something on the subject, but haven't found anything that seems to cover it (does that make me special (I did laugh at the video), but enough off topic).
so I specifically have the Samsung Galaxy Note. though I realise in a lot of ways its really just a big S2 in most regards. and I suspect several other devises that would be comparible.
I'm currentlty using a dual charging dock station which I bought cheaply of amazon, and that gives me sync and power. having looked inside the case there loads of spare room in there. and so I'm wondering about playing around with the MHL adapter and ideally something like the audio out with the official samsung dock.
from what research I've done the note senses what type of dock its in by the resistance on pins 4 and 5. now even with my basic electrical skills it seems rather easy to put in a 3 way switch to select between these
obviously the guts for the HDMI out would be from a MHL adapter, and that should be possible to power through the standard connectors on the current dock. but what I cant seem to find would be the associated parts for the audio (dont want to buy the official samsung dock just to rip it apart) (one thread on here about stripping the cable back to power and then the 3 inner wires were left, right and ground, but didn't see any evidence of that method working)
the audio aspect has another relevence for me, as I'm also wondering about a note dock/speaker set up (cheap 2.1 speakers, rehouse the sub to a case that incorperates the mUSB connector, audio components, and power, so that other than speaker cables and one power cable that'd be it (currently use a Sony NWA-3000 plugged into old pc speakers for such night time listening)
so thoughts and advise (specifically on the audio aspect)
