DIY Headphones Wiring and LED?
Part one - How does head phone wiring work?
To elaborate: I know speakers need +ve and -ve to work But all i see from a headphone jack is 2 copper ground lines (ive been told to twist those together into one wire) and Left +ve and Right +ve where one is green and the other is red.
How does this work for the mini head phone speakers?
Part Two - LED
Im trying to hook up LEDs and draw the power from headphones so it will flash to the music. How do you go about doing that? Some one made something like this with speakers: http://www.metacafe.com/watch/826934/sou...
But the video was too vague...
Part 3 - Enough power?
4-8 leds will be used. Will this draw too much power and make the headphones quiet or too silent? or does it keep drawing power from the Ipod shuffle anyways?
P.S. Im making an IPod shuffle raving eyeware rig. Sounds weird, but its pretty hot in japan Cyber punk scene. (The product is 200 usd. and the idea i have is vastly improving it anyways.)
Help please.
Headphones work with two hots (a left and a right) and one ground shared between the two.
Headphone outputs do not have enough power to light LEDs at all, so don't start.
What you can do is use the small audio signals there to trigger electronics which control the LEDs, all being powered by their own battery pack..
