first post here. I'm doing a home project, and in need of advise.
instead of me asking wild spread questions, I'll just start be describing what i had in mind.
I'm currently re-painting a Steelseries Neckband headset as it only comes in white, and wanted to add some neat things while i have the headset disassembled.
the headset have a built in microphone, but I'll rarely use it, since i have a usb headset for my computer. so i wanted to build in a jack connection for the mic, so i don't have two cables, or a dual cable, which would also make it easier to maintain eg. replace the cable.
but that's not the tricky part, the reason i wanted to create a separate port for the mic, is that i mostly use the headset with my iphone, winch support a 4 pole cable, and then use what is normally the mic. poles to run power to LED diodes i want to build into the headset, pulsing in tact with the music.
from what i understand the analogue audio signal is AC and at about 0.5 volt.
I'm not sure about the mic.
the materials i have PT.:
diodes, model no. number 1N5819, to make a rectifier. which leads me to the question whether i should full or half wave, since half wave might give a more clear blinking with less flickering, but at a power loss...
capacitor 100uf, 16 volt, for the step up
various blue LEDs, but i don't know the specifications of these. how can i find out?
i have 5 very small LEDs with resistors already attached, they they are under shrink tubing, so a can't read them. but I'll probably use the 5mm LEDs, if possible, since i have a lot, and they give more light.
12 Ohms 5% resistors
2 circuit board mini jack connectors, though i don't know whether they are 3 or 4 pole.
the headset has an impedance of 40 Ohm
last, how would i disperse the light in a acrylic disk, to give a smooth and not blinding light?
please excuse how poorly written this is, English is not my first language, and I'm new at this. i hope somebody can assist me in this project.
in the mean time i'll do some research, which i should already have before posting, but i learn 10 times faster by experience, than reading, so this will be a build and project status log.
I'm looking forward to the end result, and i hope to be able to share it with you guys.

Update
so i finished painting, and finally got around to assembly the haedset, after i got a new soldering iron. next i need to make the microphone port, and the LED's.
but so far i think it looks like porn, compared to the original:
and it looks nice with my 900D as backdrop.
i'm considering making a gold stribe on the plastic next to the pads.

*edit*
collected information:
blue LEDs run at about 3.5V, 25-50mA
AUX supply ~1V pk-pk, and 30 mW per channel, 60 mW total.
microphone line supply 2V (needs 200 to 5000 ohms impedance. (1600+ "operational"))
TRRS pins:
TIP = left headphone out
RING = right headphone out
RING = ground
SLEEVE = mic in+ plug-in power
