Here is a tiny tutorial on how to make old headphones in noise cancelling ones.
I´m a professional musician and when i record voices or acoustic guitars sometimes the audio from the headphones gets into the recording, so i started to use acoustic noise cancellers from a hardware store over the ipod headphones (but it was terribly unconfortable).
Now i mix an old pair of headphones i had with the noise cancellers, to make a more confortable (yet unexpensive) solution.
See the gallery for the steps and the process to do the project.
Here is my third proyect, it´s an level meter with led via the Headphone out of my mixing console with the Arduino UNO. Here is the device working on video (updated video in english using the Iphone Photostudio for arduino stand): Very simple, you read the voltage from the headphone output… Here we are going to use the system of a KVARTA Ikea Clock, and make us an LP clock. Here is the part list: - 1x Ikea KVARTA clock - 1x LP We start dissarming the clock, first taking off the clear cover of the top, so we can access… A very dumb and simple, but really good looking example of the Arduino UNO and LEDS. The effect of the Knight Rider Car. The idea with this example is to learn how to work with arrays on the code.
