How to make a Noise Cancelling Headphone for free.
Here, I will show you how to make an active noise cancelling headphone from nothing but laptop scrap.
The microphone receives the unwanted noise, this noise will be inverted and amplified by opamps and then send to the speakers.
The inverted signal will neutralize the noise you want to disapear.
Materials:
Two old laptops:
2 Microphones
2 Speakers
A soundcard/motherboard from a desktop/laptop for an OPAMP IC
Old circuit boards for some capacitors
The wiring diagram can be downloaded via the link below:
