@fribse i just use a logitech usb webcam for the mic

@sdetweil Ok, so any cheap lavalier microphone, would be great to have something that was mounted in the frame, I know, details, details, details, but as I’m already on the edge of waf, it needs to be well designed :-D

If you are of ok with basic soldering, you can follow this steps.
The cost of such very sensitive mic will be 2$.

I have made this mic myself and its sensitivity is very high.
Mic is located behind the glass and sensitivity level set to 5%.
With this set-up, I can speak normally 1.5-2.5 meters in front of the glass and mic+Raspberry recognizes what I am saying well.

@Serge Very interesting, I even have the 4466 mic here :-)

Hello,
I’m using the Sony PS3 eye. As there are 4 microphones inside the webcam, it allows me to speak to the assistant at more than 4 meters in my living room despite the ambient sounds (TV, music …)
