MK808B Plus Antenna Modification - Android Stick & Console Computers General

I was curious if anyone has tried to solder one of these on the board? I was thinking that then I could just drill a hole in the side of the case and put an external antenna mount there. The other end of the antenna would then just plug into this socket.

How to make an audio adapter

Hi, I've been using an audio adapter from PocketPCTechs (http://www.pocketpctechs.com/detail.asp?Product_ID=PPCPADPT01) with my XDA 2... However, the microphone doesn't work with this. Even if I plug in a regular mono-headset with microphone, that part doesn't work.
So I thought I'd cut the stereo headphones off of the headset that's included and wire that up to a cassette player adapter. My problem is that the wires going to the headset speakers are coated with some kind of paint along with a fiber which makes it very difficult to make a connection with the wires in the cassette player adapter. I took it to an electronics repair shop to see if they could solder a 3.5mm female audio plug to that end, but they said they couldn't because of those types of wires.
Has anyone had success in modifying the included stereo headset to play through a car stereo while also retaining microphone functionality (for Voice Command or Phone calls)??
You will need to crimp some metal contacts onto the wires to make a good electrical conection, but you MUST do your soldering onto the crimps first otherwise you will just melt the wires off of the crimp,
The wires are special lightweight metal coated plastic filament designed to reduce weight and enhance audio since HF signals only travel in the outer edge or a wire
i used a stanley knife blade to carefully scrape the plastic off but the metal is so thin it just crumbles away and the solder connection doesnt stick that well to it either the stuff is just like factory made and this kinda stops you modding it what i done was use a 3310 h/f kit and cut that up and solder a 3.5mm end to it worked great

Does anybody know the assignments of the 4 conductors of the XDA II headset plug? I'm guessing that the tip of the plug is for the left speaker, the next conductor is for the right speaker, the next is for the microphone, and the last is the ground connection. Is this correct?

No it isn't, the connector at the bottem is the same as the XDA 1 : http://www.xda-developers.com/connectors
On the XDA 1 audio out worked simultaneously with the internal speaker and mic. On the MDA/XDA 2 audio is rerouted to the bottemconnector if you ground Pin_19... The internal speaker and mic wil be disabled.
btw. i sucesfully managed to solder the previously mentioned wires... I went as far as opening a Nokia 8110 headset, rewire it internally and close the mic again You should carefully tin the wires before soldering them...
i recently did this also
when i bought my phone from t-mobile, i had my friend who works there huck me up with a extra usb sync cable
the connection that connects to the phone has 2 philips screws on it. if ur careful enough u can take it all apart to the point of getting to the pins / wires
the usb cable with the power inlet on the back of it up by the xda connector, has enough wires in it to cover you for audio left and right and mic + if u use a common ground (1 ground across all 3 connections)
this is important to know when your alpine cva-1004 uses a common ground and wont engage the video unless all 3 wires are grounded
anyways... i was able to use a ginsu kitchen steak knife (sharpest knife i had) to cut away the rubber shielding on the actual wires holding the wires to the pins. otherwise u could use ur soldering iron and just burn threw it, just try not to breath it in.
then u just un solder the wires, reroute them to the right pins. if u want, use some hot glue to seal them back up, but if u solder them strait enough, the casing will protect it enough
then clip off the usb end, i took a spare component PS2 video cable, the wires were thin enough to integrate nicly into the usb cable, clip that, strip it, solder those in. clean everything up with some black electrical tape and ur done
mine ? my alpine cva-1004 has a remote mute wire. plug the phone into the aux in on the radio in the car, run a mic cable and audio cables (or use speaker phone) and u have the closest thing to a in car cell phone.
also works nicly for listening to mp3s in the car, but my xm satelite radio has that pretty nicly covered
just my 2 cents, but its not hard. i didnt wanna screw up the cables, so it took me about 2 hours in total to do a nice job.

oh yeah, FLUX is key. it may also be called tin, but iv allways known it as flux.
dip the tip of the soldering iron in the flux, then get some solder onto it
purpose of flux ? it makes the iron slippery to the point where it will hold solder (in liquid form) but once the solder touches the wires, release it from the iron
its like non stick spray for soldering irons
you may also be able to put the flux on the wire / connection itself, but iv never done that. little flux on the tip of the iron should help alot
non leaded flux id suggest, but if u dont know what flux is or hot of a iron u should use, u probably shouldnt be doing this project

Tin = solder, sorry i'm Dutch Didn't use anything else, no flux.
A lot of ppl just stick two wires together and try to fill the gaps with solder
This might 'work' with relatifly thick copperwires, but not with these...
Put some solder on the wires before soldering them together.

HTC Fuze Speaker Connector on Mainboard

I bought a Fuze off ebay and the previous owner in repairing the phone rip off the external speaker wires and broke off the connector attach to board.
The solder pads and still there, actually the 2 posts still present on the mainboard.
Where can I buy the speaker connector? so I can re solder it back onto the board?
I can post pics if needed to better explain.
My last option is to buy a parts phone, will a sprint htc touch have the same speaker connector? or will it have to be another fuze.
My other option which I don't want to do is dig up my parts bin for a generic connector, so it can be disconnected to take apart.
If you are skilled enough to re-solder a connector in the first place, why don't you solder your own connector instead of trying to replace the original one. Better yet, solder a wire to the board to an alternate connector,then replace the connector on the speaker leads to the matching alternate connector. I already tore one speaker wire when opening my Fuze, because its is too short. Luckily I did not yank the connector so I was able to purchase a replacement speaker for $10 and reconnect.
I wanted it look stock, but it's hard to find a cheap parts phone so I will just solder on a different connector.

External antenna plug

hi,
i lost my rubber plug that covers the external antenna port right under the kick stand.
does anyone know where i can get the replacement plug?
thanks.
could you find a broken thunderbolt on ebay and salvage the part from there?

External Antenna Port

I'm looking for a cable to wire to the external antenna port of my I9505 S4. I need to know if there are any thinner cables that attach to this port so that I can mount a under the cover antenna for an aluminum battery cover. I know that people say that putting one of these cases on my phone will cut back on the reception so I want to fix this by perhaps mounting some kind of an antenna under the back plate, but have so far not been able to find a cable that will connect to this and will still be able to have the case on my phone. Telco makes that gigantic cable that attaches to large external antennas, but I don't want this. I either want to have something like a laptop antenna under the backplate or just use the whole door as an antenna.
So that being said, let me restate my purpose. I need a thin wire attached to a small plug that uses the external antenna port on my phone. If anyone knows where I can get one, let me know, thank you.

Help sourcing a part?

While soldering a new power button ribbon cable to my mainboard I accidentally bumped one of my NFC antenna pogo pins and soldered it solid.
As expected all attempts at soldering it only added more solder. I have ripped apart a stash of phones I had laying around and found a few pogo pins in them all too large.
Here you can see an image of the mainboard along with some example pogo pins.
something of similar size or a suitable method to make nfc great again would be cool!
