22'' Display + 40cmx50cm IKEA Frame + PIR Sensor

TGBB

Isn’t a 40/50 Ribba frame at Ikea…?!? Thinking of using this or two back to back. Also can you quote the one way reflective film you used as the link was just a link to Ebay.

Hey ryck,

is it possible to show us some pictures from the backside how do you placed the PIR ?
How do you fix the PIR and, if possible, the connection from the PIR to the raspi …
And what hight did your RIBBA have?

Thanks!

ryck

@MyMirror Sure, I’ll try tonight, but I can already tell you:

The PIR is attached to the bottom of the frame with some bluetack
The PIR sensor is using this “module” so just follow the instruction (ie, here)
My frame was 40x50, but you have more options, just choose the one that works better for you (and fits your screen, of course)

Good luck!

ryck

@TGBB Yeah, just two 40x50 RIBBA frames glued back to back…
Any reflective film will work. Seems like the link I posted is not valid anymore, but you could use something like this…

Hey ryck, thanks for the details.
Did your monitor shows information like “no HMDI found” or “lost signal” or anything like this, when the PIR turns off the screen?
If not … what have you done to suppress the text/infos?
Or is your monitor smart enough to do that for you?

@MyMirror I don’t get any text on the display when it goes off, maybe the display is smart enough? Are you using the same software to turn it off?

Hi @ryck,

i think it is python …
I just get “Python 2 (IDLE)” on my menue.
I’ll try to force an update with
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install --reinstall python3
but, after reboot, nothing happens. I’ve got just python2 on my menue.
…
(After searching in the main menue Editor …)
OK - found python3 but without IDLE) - but this should not be the problem, or?
But if it is “easy” to install the IDLE - can you give me a hint?

I use pin 14 - as in the pir.py written - nothing happens … :-(

I think, it is the missing line 7 in the pir.py.
You wrote:
You have to change line 7 to the location of the pir.py file like this:
ExecStart=/usr/bin/python /path/to/your/pir.py

But in my pir.py i didn’t find a line like this …
Can you help me?

Thanks

@MyMirror in the pir.py file you need to change only one thing, the GPIO data pin to which the PIR sensor is connected (you can double check yours here: https://pinout.xyz/). The line is this one: https://github.com/deg0nz/MagicMirror-Display-Controller/blob/master/pir.py#L8

That should be all.

The line 7 stuff is for the service (ie, run the script automatically every time the Pi reboots) and is in a different file: https://github.com/deg0nz/MagicMirror-Display-Controller/blob/master/pir_sensor.service#L7

Merry xmas :-),

thanks … your script works - my monitor not really :-(
If your script power off HDMI i’ll get a “HDMI”-Logo and “no Signal” … bad :-(
It seems that i have to buy a different screen.
Which one do you use? Is it available as 32’’ ?
