PIR sensor behind 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…
-
@RedNax Can you share a picture? 😊
-
@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…
-
@RedNax Apparently some monitors seem to allow for external commands to change the light levels:
