    @Knox Yeah, thanks, my Fresnel lens isn’t even fixed to the PIR sensor and comes off right away if you don’t find some way of keeping it there ;-). But you’re right, didn’t think of that, it’s actually covered by this plastic dome. Maybe if I install the PIR sensor in the frame of the mirror and cover that section of the frame with acrylic glass, such as Plexiglas, it might work and look alright. Will try and test if my sensor detects IR behind a sheet of acrylic glass.

      that would be a good test, but just note you’ll be lowering its effective area. Which for a mirror might be fine, as you normally stand directly infront of it.

        Sure, I guess I’d have to play around with its sensitivity, will keep you updated on the outcome of my tests

          Pir isn’t really an option behind glass. There’s a cam based solution which works through the mirror.

          That said, my mirror is full sized and the pir peeks out the bottom… You’d never know it’s there unless you know where tot look…

              @Cato No problem… anyone care to donate to the WWF Panda?
              There’s a PIR sensor on the bottom of the mirror, out of eyesight. It detects … well… hot legs :D

                @RedNax Your mirror looks really cool.

                Our mirror will be mounted pretty much at eye level so having the sensor at the bottom of the frame won’t be an option for me, but I’m already experimenting with covering the sensor with plastic stuff ^^.

                Is there an xkcd module I’m not aware of?

                And may I ask where you got your glass? Some of the pictures I’ve seen look like you can still see the monitor behind the glass but with your mirror that doesn’t seem to be the case.

                  @yo-less Thanks!

                  The mirror is from a dutch webshop… At night, when there’s no other illumination you do see the backlight of the screen shining through… In the daytime it looks like the picture.
                  I’ve been pondering altering the backlight/brightness of the screen according to ambiant lightlevels… unfortunately this is only controllable by navigating the screens menu as opposed to discrete buttons…

                  Oh, and yes… there is: https://github.com/RedNax67/DailyXKCD

                  It’s forked from the original author… Ive added the random comic on non comic days…

                    @RedNax Alright, is that the case with all types of glasses? I guess it would be?

                      @yo-less It think all mirrors suffer from this… You need enough brightness to show things in the day… Which will be overkill at night…
