    @Aly I found documentation for the sensor that a resistor would indeed solve the issue here. I can set the delay up to 200 seconds with a 250k resistor, so I ordered one and will report back how it went.

        @Aly I misspoke, shouldn’t have called it documentation. Rather, it was this picture:alt text

        Which appears to be a translation from the Chinese original picture.

          @Nususu

          so if we remove the R6 resistor the delay would be 30s ?

            @Aly yes, it would appear so. I just bought a soldering iron and resistors which arrive tomorrow so I’ll perform a couple tests: 1. Remove r6 and verify that it’s 30s. 2. Add 250k resistor and test duration.

                @Aly I tested this today - I put a 250k resistor on R6 and it increased the timer to approximately 25 seconds. I forgot to test without a resistor. Let me know if you end up testing that.

                  @Comunnity

                  If it comes to the thickness of the mirror: Would you either recommend webcams, etc, behind the mirror or as I thought create a CAD-print plan for a 3 D-printer to hide the camera behind a… actually I have no clue how to call it … a “string” of maybe a lamp?

                  Do you guys have recommendations or Best Practices?

                  I saw some awesome bathroom project in this forum but no one 3D printed his lamp or LED. My roommate has a 3D printer so I am thinking about to integrated a camera in one part of an LED lamp which is on top of the mirror.

                  Maybe someone tried this idea before me. Hope there are some Best Practices on how to do it.

                  As always I would like to thank you for your awesome feedback guys.

                  Kind regard from Hamburg, Germany,

                  Paul

                    I really like the way this guy mounted the camera on top of the mirror: https://forum.magicmirror.builders/topic/6952/my-mirror-so-great
