One question: du u use a pull-down or pull-up resistor?

If not this might be ur problem, the gpio will detect random activation, it really needs a pull-up or pull-down resistor to work properly.

Hope it helps a bit.

@Kastore It depends on the device but the color of the wires is not random. Typically red = + but could either be 3.3V or 5V. Black will be - or grd. I can’t ever remember all of the pins but if you do an image search on GPIO Pinout you will get a ton of pictures of how all the pins are laid out.
Yellow can be a bit more arbitrary but if you don’t have the device literature you can do a search on the devices name and/or number

I tried this app and was quite satisfied

@fozi

So I reinstalled the whole module and tried to get it back to work. I swapped to the GPIO_4 but unfortunately the Sensor is now not responding at all :/

Plugin it back to GPIO_17 it instantly works .

HOWEVER - the config is still on 4 but it is accepting the pin 17…

So there is something wrong but i am inclinded to “leave it as be” … it kinda works as i want, alltough i cant “control” it as intended by the module

Well the issue with the Pi being stuck at the splash was already happening before the console… maybe it was multiple things?

The pi started up and forced me to log in suddenly (no clue why). That is what got me started on checking the SD card. Since i didnt get access via remote (“wrong” username) I had to swap to console, deleted files and couldnt figure out how to get back.

It works again ^^

Regarding the disk-space. I got a 16 gb sd card.

However it was the 3-4 previous versions of MM2 I forgot to delete from the bin.

I will keep an eye on it and hopefully never run into that problem ^^’

Really appreciate the help! Thanks alot and big thumbs up to the community here!

Also added the “solutions” to the first post so people may be able to find a quick solution as well.

@MadScientist said in Slim display due to thin space:

universal LCD controller board

The problem with having it “not mounted” to the door itself will be the cables. I will keep on using the door so id have to make sure they dont break or get stuck or anything.
The power cords are strong enough so i dont have to worry - but the LVDS cable i dont trust toooo much ^^

I guess i will be building a “box” on the top side of the door and have the whole equipment in there. That way it is “out of sight”, near a hinge and got a low leverage.

But I may order one of the universal boards and mount that to the door as well. Just to reduce the size. Very nice tip from you! Didnt know they are SO MUCH THINER! Wish they had used that right away in the BenQ monitor ._.

And the air will flow via some airholes on the bottom and top - like a chimney (hope that is enough ^^)
