I have just finished adding a mod on my controller.

The mod adds one button for push to talk (PTT).

I got tired of flipping the privacy switch on my mic cord, I will be posting the
youtube video and images after I get it put back together.

I have tested it, it works great!

Thats a neat idea. I don't think I've seen anyone else do this. Good job.

I haven't see it either, thats why I did it.

I am the first person in the world to wire a ptt button on my 360 controller.

Video tutorial coming very soon.

360 Controller with Push To Talk

This tutorial will take you through the process of installing a normally open momentary switch
to use as a Push To Talk button.

Notice:
This modification will void the warranty on your controller.

Warning:
This modification could damage your controller, I take no responsibility for your actions.

Tools:
- Soldering Iron
- 20 - 24 gauge wire
- SPST Normally Open Momentary Switch
- Voltmeter
- Drill/Dremel with bits

Notes:
This project was completed on a new controller purchased from the store. This controller is most
likely manufactured in the present past. I can not confirm if this is true and works for older controllers
but I can't imagine it would be much different.

Process:
Disassemble Controller (there are lots of tutorials on this, just search)
Locate the "Mic Pin" on your controllers PCB (rcrayon.com/ptt/mpin.png)
Locate the trace for "Mic Pin" (rcrayon.com/ptt/mtrace.png)
Use an Exacto knife to remove a section of that trace (careful not to cut anything but that trace)
Use an Exacto knife to carefully scrape the epoxy resin from the left and right side of trace (rcrayon.com/ptt/mcut.png)
Solder a wire to one side of the trace
Solder another wire to the other side of the trace
Run the wires to your switch location
Drill/Install your switch
Connect wires
Reassemble Controller

Additional:
You may also open the case on your mic cord and bypass the privacy switch.
This is done by unsoldering the M + wire from the privacy switch (both sides)
and connecting a wire or similar between them, hence bypassing the privacy
switch while the volume still works.

Testing:
Before inserting your batteries, place a voltmeter in continuity mode and place
one test lead on one wire and the other test lead on the other wire where they
are soldered to the board. When the button is pressed, you should get tone or
continuity between the two wires, when the button is released you should have
an open circuit. If you don't you haven't cut all the way through the trace.



Images coming soon.

You might want to trim the top half of the shell as it looks like the wires are getting pinched, but great tutorial!!!

Yes.

This is very crude, some of my first attempts.

I have trimmed the top of the case and cleaned it up.

I just added a 1.5v green led with the clear plastic piece and wired it in with
the ptt button, here is what it looks like with the PTT button pushed...

Here is the URL for the led I used.
http://parts.digikey...sp5093upgc.html


And who said I can't put super bright led's in a wireless controller for lack of a 5v rail?

I though also about battery usage, the light is always "on-off" it never stays "on" for any
period of time - at least not enough to have a noticeable drain on the batteries (watched with
voltmeter from full power to drain).

It's also serves as a warning your battery voltage is getting low as once the volts drop
enough, the led will not illuminate.

I ran the power for this off the OCT so it's true off when its off.

Will post images soon.

Very clean mod, if I were using it though I would forget to press it I usually just unplug my mic. The only time someone has heard me say something I didn't want them to hear was when I was at a mates and we didn't realise his Kinect sensor had a mic. Perhaps it would be possible to put a switch in the kinect sensor not a momentary one though...
