How to make your own Noise Cancelling Headphone using broken computers Part 1 - DIY

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:

[@ashkansolimani4290]

do you have digital diagram and code by arduino ?

[@scraptech4736]

The digital diagram you can find in the link in the description! There is no need to code since it is a pure analogue setup.

[@unlazi7412]

The digital diagram is not working

[@cking9145]

Don't you need to code?

[@scraptech4736]

This is a complete analogue solution, no digital settings or coding is necessary
