I have it incorporated in the frame. I drilled a 2 or 3mm hole in the front of the frame and a 8mm hole from the back which only goes half way through. The 8mm are perfect to mount the PIR sensor without the lense. The mirror only activates when you are directly in front of it and it’s hardly visible.

According to the datasheet my LCD panel weights 2530g. Thought it’s much lighter… my complete mirror with 6mm mirror glass weights slightly above 8kg. I think that’s not too much. The glass has probably the highest weight impact on the project. Thinner glass will reduce the weight drastically.
I am using only the naked LCD panel with an universal LCD controller board (check for V56 universal LCD controller board on ebay or aliexpress) and a 12V/50W LED power supply. All in a self-made wooden frame. It’s hanging stable on the wall for pretty much exactly one year now.

For the multi-screen part: It depends on multiple factors whether you can see them or not. First is the brightness of your LCDs. If it’s set too high you’ll have backlight bleeding (the black will not be fully dark anymore). Also it depends on the transmission values of your mirror glass and the light environment of the room. It’s best to find a location with constant light conditions. My Mirrorpane Chrome Spy has a transmission of 8%. I’d say that’s lower limit. If I could find one, I’d go for 15% or maybe even 20%.

In the first picture what does the multi-meter show when you measure black (should be ground) against the red wires on the on the right hand connector? Can you also tell me the what LCD panel it is exactly? best to make pictures of the stickers in the back. I’d look for the datasheet to see whether or not it is running on 5V. If so there should be a 5V rail you could harvest. Otherwise I’d think there would be at least a 12V rail somewhere. You could use that with a buck converter to get down to 5V for the Pi.

I got a broken 24" LCD monitor for free. The panel itself is working fine with a cheap universal LCD controller board.
I don’t know about your monitor but it shouldn’t be “extremely heavy”…

If you want to use more than one screen you’ll probably have to use a Raspberry Pi for every screen. Or you use a regular mini PC or laptop with dual monitor support.

I have a sensor that allows changing the sensitivity but for me the lowest was still to much as it got triggered when somebody walked by outside my house. I am using a PIR-Sensor now.

@bachoo786 The sensor should have three pins: VCC, GND and signal out. You connect them the same way you connect a PIR sensor and it should also work with the same MM module MMM-PIR-Sensor.

I was just about to post the exact same as @lavolp3. That should work for sure.

Google calendar? In your Google account you should find somewhere a calender link in this format https://calendar.google.com/calendar/ical/.../private-...../basic.icsthat works for sure. I am using it on my mirror. Nextcloud/Owncloud also works if you want to run your calendar locally.

@pnizet Still quite pricey for my taste but I’d love to see a infor-board project based on it. So go ahead and don’t forget to present it here :smiling_face_with_open_mouth:

Btw, it’s not my topic. @Gooral was the one starting this thread. :slightly_smiling_face:

A mirror with a higher transmission should also reduce the backlight bleeding since you won’t have to increase the brightness as much, creating a better black and therefore having better contrast.
