add-extra-audio-jack-to-your-treo-part
Finally, I have some time to post some basic information about my Audio Jack Hack. I have been working on this project for some time and have actually been using and abusing it for a while (broke my first one in Vallarta 3 months ago). I guess you can call it real world testing, but I have also done other testing on it.
The design has gone through various design iterations and improvements, but still only exists in "hacked" form. I actually plan on manufacturing come next year but for now I am working on more exciting designs. For now I will post pictures if my design and see what kind of feedback I get. This is one tough hack to do and I have ruined many antennas!
Antenna functionality is not affected, but I have also been experimenting with modifying the internals to get something better tuned for the 1900 MHZ spectrum. Also, the original jack still works and you can use the headphones on either jack for phone calls. Wired headset still works and will work on new jack with adapter.
Speakerphone use via powered speakers should work and I have a working prototype, but is does not quite fit in the antenna... yet!
Also, I have submitted a patent application to the United States Patent Office for this design.
I hope you guys like it!!!

this is definately the one ive been looking forward to the most :)
yes, very exited about this one.
SO.....how do you do it again?
Is this an introduction on how you've done it? Are you going to post a full fledged guide in the near future :D ?
btw, looks great man !! :)
is there any radiation transfer seeing that headphone connector is so close to the antenna?
it would be pretty cool having a 3.5m jack on my treo.
can you really patent an alteration to someone else's product?
Yes, if there is no intervening prior art, you can patent an improvement to someone else's product (or patent).
where are the instructions to do this?
My first prototype did pick up some radiation on one channel (from the tip). The latest prototypes have less metal and have better insulation
Please don't advertise your website on my blog.

Let me be the first to accuse you of a Photoshop job -- it's too cool to be for real.
In other words, GREAT JOB!!
your comments are uncalled for... well, until I post the Treo 650 Tequila decanter w/antenna spout.
Thanks!!!! :)
why shouldnt i just use an adapter with the jack thats already on the phone?... i can see the merit in not having to hassle with adapters though...
Adapters suck!!! Plus, the original jack is located in a terrible place.
The top location is much better when you carry your phone on your belt or pocket. Also, adapters put extra stress on an already delicate 2.5mm jack.
I'm working on mine now... disassembled the antenna. Now I'm going to Fry's to get a soldering iron and the wire. I have an extra broken treo to use for parts if I break anything.
Stress kills - especially the stress of a standard headphone (3.5) adapter on the exceptionally weak 2.5 jack on the Treo. Fantastic idea you have here. Hope Palm buys it and puts it in a future Treo. Too risky and potentially expensive for me to try doing myself. Great blog though and I may use the info to help fix my 2.5 jack.
I have to agree that the jack's location is completely illogical (as are many of the Treo's design features and software). The use of an adapter is pretty tricky, and it DOES almost guarantee that the jack will loosen over time.
Luckily, I've had so many problems with this device (6 exchanges in 3 months), the Cingular store just exchanges them without question. :-)
GREAT suggestion, though. I may try it when the Treo 700 comes out, since it's doubtful they'll do much improvement (except for the software).
You gotta get me one for a hook up :)
great idea! Im on my 5th 650 and I think my warrantys about expired.put me on your list of potential buyers!

Ready for the flood of questions? Here we go:
-If I'm listening to stereo headphones (no mic), and a call comes in, will the phone be smart enough to use its own mic to pick up my voice?
-If considering the Seidio G2350S cradle, with built-in GPS receiver. It's got no audio-out, and the cradle blocks the 2.5mm audio port from being used. However, the cradle itself does not plug into the audio port. As a solution to this problem, I'd like to make a cable that goes into the 3.5mm antenna port, and splits between an external mic (for my car visor) and a stereo output, which I will connect to the AUX port of my car stereo. Does anyone out there have any comments as to how this would work when running Tom Tom 5? Assuming this cable idea works (which I can't see which it wouldn't), should Tom Tom automatically route the audio to the stereo out?
-Tom Tom 5 also has a feature to block on an incoming call, and then resume afterwards. Does anyone have any experience with this, while using the 3.5mm antenna port? Ideally, I'd like to be able to take the call through my externally wired mic and car speakers, just as I'd expect Tom Tom to work.
Any thoughts at all are appreciated. I'd hate to get stuck with useless hardware and find out I didn't look hard enough for someone who already played the guinea pig role :)
Cheers.
Bret,
This many questions should be sent to my email, but you have many options:
1) hack you cradle to add an audio jack (or send to me)
2) add a 2.5 mm jack in the antenna with idential fuctionality to the original
3) add a 3.5 mm jack and lose the 2-in-1 functionality (stereo or mono+mic... no stereo+mic
4) add a special 4 conductor (4c)jack (I have some) but you will need a 4c plug ( I dont have)
My biggest question: where did you attach the wrist strap??? This is my biggest complaint about the Treo, that there is no scar/hook for attaching my safety/drop strap.
Oh, other than the damn audio jack cutting out, of course...
I just had the jack installed and it works like a charm. Thanks again for the wonderful job.
Did I miss the instructions for the 3.5mm antenna jack? or is the only option to send my phone to you to do the hack?
I did this.. and it didnt work :(
I didnt use this part though Kycon P/N ST-3500-3N
Instead i bought crappy radios.. and took out the jack..
could of that been the problem??
I did this like... five times still no luck
now my original jack from the inside looks like crap... still works.. but.. E-O!!
would rather replace 2.5mm jack on bottom with 3.5mm one, and rely on my Bluetooth headsets. I never use wired headsets anymore. Wonder if using that jack disables the mouthpiece?
wow... 280$ an hour, that's pretty steep labor rate. seems like 30 minutes of work could be priced a little more competatively. I'll learn how to do it, teach a mexican and i'll charge 30-50$ to get it done just so you don't rape these people.

I am very interested in getting one for my Treo,
please let me know how can i contact you to get the product
Arturo
I am very interested in the Atenna plus the audio jack.
Please send the price of the antenna to artmend15@gmail.com
I tried to put a 3.5 jack in the 2.5 spot. After 4 tries, I could not jet the new jack small enough to allow solder lines and still get the case back together. I planed to get one of the "flat" ant and use the new jack on the bottom. It is clear that is not going to happen.
Is there a guide to do this mod? Right now I have NO audio jack. Looks like stereo blue tooth head phones are on the way.
For those interested in the software method for this I would recommend Headcold. A freeware app that redirects audio.
Hi,
I came across your blog and thought you'd have the technical experience to help me.
The Treo 750 has an audio output which is female 2.5 mm, 4 conductor. My headphones have a male 3.5 mm, 3 conductor. So to connnect the two I can buy independent plug and jack but how do you string them together - make the connections.
Any idea on how to connect a 4 conductor audio plug to a 3 conductor audio jack.
Thanks,
Sam
kablamo!!
Do you still offer 3.5mm jack hack?
Great blog.
Thanks
Nick
