I just got my mirror up and running and was trying to install the PIR sensor module provided by @paviro (https://github.com/paviro/MMM-PIR-Sensor) but it doesn’t seem to be working. I followed the step by step instructions as written and still the screen does not turn off. I even stuck the sensor (still wired up) under a box and no luck.
I bought these PIR sensors (http://a.co/aYDzwAS) and am using these to plug in the sensor http://imgur.com/a/VEu0F . They are connected directly to the sensor with jumper wires.
My modification to the modules config file looks like this.

{
module: 'MMM-PIR-Sensor',
config: {
    sensorPIN: 22,
    powerSaving: true,
    powerSavingDelay: 0,
    relayOnState: 1
    }
}

I also ran the command /opt/vc/bin/tvservice -s and receive the output state 0x120006 [DVI DMT (68) RGB full 16:10], 1920x1200 @ 60.00Hz, progressive

One thing I did notice is that while running through the install process, I ran sudo chmod u+s /opt/vc/bin/tvservice && sudo chmod u+s /bin/chvt but it said chmod: cannot access 'bin/chvt': No such file or directory

Anyone able to help?

First time mirror builder here and I’m looking to add some volume buttons to the side of my casing to control music (such as volume, pause/start, skip track/back) and for the life of me I can’t find some cheap buttons. Does anyone have any advice on where to find some? Also, what would I need to install buttons, just the buttons and jumper wires?
I’m running on a pi 3 and I’m in the US if that makes a difference.

I think I got lucky with it actually being the micro-SD card. I’ve been using a SD card adapter to fit into the SD slot in my computer, and unfortunately there’s only one of those on my laptop :P

For some reason, when I had the old card, formatting it (even when it was completely empty and fresh out of the box) took at least half an hour. Now with the new one it only took about 5 minutes.

@Mykle1
In case you were curious at all (or someone in the future finds this), it turns out it was a problem with the micro sd card. The one I had was a 32 gig Lexar micro sd card. I took it back to the store and swapped it out for a 32 gig SanDisk mico sd and this one has been working perfectly.

Thanks again for all of your help, you’re awesome!!!

@Mykle1
I’m about to go return my sd card and see if I can’t get another, but wanted to make sure before I mess with the new one that I’m even formatting it right.
I’m using the program “SDFormatter”, setting the Format type to “Full (Erase)” and the Format Size Adjustment to “ON”
Does that sound right to you?

@Mykle1
I just cleaned everything up and went step by step through the instructions I mentioned before (even bypassing NOOBS and downloading Raspbian directly then flashing it to my sd card, but I was only able to get as far as $ sudo apt full-upgrade, during which it fails. It runs for a while then towards the end it says

My entire desktop has gone grey, all icons at the top (cmd, chromium, woflram, etc.) are just blank file images that don’t do anything…
Do you have any advice on fixing this? Do you think it could be a problem with the sd card itself and I need to get a new one?

@Mykle1 Okay, I’ll give it another shot. Thanks again!

@Mykle1 Yes I am running on a Pi 3. Also I just ran the cat /etc/os-release and it gave the exact same output as you wrote, so it is running jessie.

I think I will wipe and re-install, but do you think using NOOBS like I have been will suffice since it does say I’m running jessie?

Also, sorry for the million questions, but could you step me through downloading the latest Node.js as well as cloning the repository? When I tried to download just Node.js a couple dasys ago and ran sudo apt update then sudo apt full-upgrade (as per this guide http://thisdavej.com/beginners-guide-to-installing-node-js-on-a-raspberry-pi/) I get some errors (it’s been a couple days since I did this so i forget what the error was)

Thank you for taking the time to reply :)

When I try to run the bash command to download and install MagicMirror, I get the error…

Note.js installation Done!
Cloning MagicMirror...
fatal: could not create work tree dir 'MagicMirror'.: Read-only file system

I tried to run the bash command again, but I got an error telling me that dpkg was interrupted and asked me to run another command, so I ran

sudo dpkg --configure -a

and re-ran the bash command a 3rd time, only to arrive at the error

E: Sub-process /usr/bin/dpkg returned an error code (1).

Some additional information:
I’m running the command as pi user.
I’m running Raspbian with PIXEL because when I download NOOBS to a micro-sd, ‘Raspbian’ doesn’t show up as an option (even with ethernet connected). I was assured by some people on reddit that Raspbian with PIXEL was the same, just with a UI.
I’ve wiped and re-installed NOOBS at least 4 times on this micro-sd card, taking about an hour each time, and all I want is a working mirror :(

Do I need to go about a different way of installing this software? I’m unfamiliar with linux so any simplified version is appreciated :)

@Iron_Reptar Just for fun I decided to try to rerun the command again, and it first said that “dpkg was interrupted.” so I ran
sudo dpkg --configure -a
Like the screen told me to, then re-re-ran it, to arrive at the error "E: Sub-process /usr/bin/dpkg returned an error code (1).
Help, all I want is a working mirror :(
