@blaukon hey well done man. Amazing job.
Please help me understand the following:

how did you attach the monitor and the mirror together?
How did you hold the monitor to the frame?
Is the frame strong enough to hold the mirror and the monitor?
Thanks.

sadly, I do not have more pictures or access to the mirror at the moment - alt text

But I made 3d modell in tinkercad to show you the necessary construction:

front:

-> orange: mirrorglass (bigger than the hole)

-> monitor right onto the glass

backside:

the frame is massiv, about 2-2.5cm wood, I have absolutly no worries that this frame would brake by itself
and that’s basically how it’s mounted:

Hi, I have seen the video and its great work.

I have similar setup with yours i.e.: AssistantMK2 and Kinobo USB mic (not Akiro but that mini USB one) and it is nowhere as sensitive as yours. I have to speak almost next to the microphone for the hotword to activate AssistantMK2. This reduce the mirror usability considerably.

Can you please let me know what you have done to increase the sensitivity? so far, I have increased mic to max sensitivity with ALSA mixer but still nowhere near yours.

Regards,

blaukon

hi, all I did is to set a higher but not too high sensitivity via alsa mixer or on desktop - right click on audio - audio input - input device settings and adjust the sesitivity:

did you test your mic? arecord test.wav -> aplay test.wav?

Thanks @blaukon

Yes, i tried to raise the sensitivity via UI and Terminal. Volume from arecord is still very low.

If I replace the mic, is it direct replacement or any configuration required?

blaukon

if your recoding is still quiet, even when you’ve raised the sensitivity, it’s mostlikly your microphone
I’ve bought this one https://www.amazon.de/Kinobo-Mini-Akiro-Mikrofon-Windows/dp/B00NSOWWIS
and also one that looked like 99% the same, was cheaper, but wayyy worse in comparison.

@blaukon hey so are you saying your mirror glass is bigger than your monitor?

I have the issue if the mirror glass is bigger than the monitor then the edge which is not covered by the monitor it needs to be painted black or covered with a black material. This causes reflection issues on the mirror from the front I.e. you can see distorted images on the edge I.e. the image looks stretched…

hey, as far as I can remember, the glass is slightly bigger than the monitor and the frame is also slightly bigger than the glass, no tape was used, since you only see the monitor in the frame and not the “frame” of the 27" monitor.

tried to show it graphically with my old expanded notebookdisplay:
