@madscientist that is what I am afraid of as well, the metal coating sure does not help… but worst case I will put them on the aluminum frame below from the outside and a nice cover on top

I got the mirror from here: Glas-star.de

Hi guys,

just an update on the mirror. Finally the glas has arrived. I am very happy with the quality and the 50mm edge that has been painted black. There were a few stains on the backside which I had to clean manually.

Overall I am pretty satisfied with the results, but I have to change a few things:

What I am happy with:

• quality of glass (polished and round edges)
• Monitor appearance
• aluminimum frame and design (even though it needs to be changed, see below)
• sound quality
• The quality of the double-sided tape (seems like this is minor, but it is so strong I have no doubt it will hold the glass)

What needs to be changed:

• I changed the PIR Sensor to a radar sensor (RCWL-0516) which works flawlessly behind the glass
• The wooden white background reflects too much sunlight during daytime so I have to get a black one
• The Nielsen frame is 50mm too large. The reason behind that is that they measure the inner length but since I put the mirror on the outside it is 50mm longer. It does look okay, but I want the frame to be more inset. So if anyone wants a Nielsen frame for their project. I give mine away for free or a few € whatever you feel is appropriate it measures 95cmx75cm and can be shipped in small pieces and has the high quality double sided tape attached. I could have also gotten a bigger mirror, but obviously that is too expensive
• the cheap capacitive Sensors from amazon don’t work well behind the glas so I am now getting these MT0.1N-NR. The datasheet looks promising, of course 10x more expensive…

A few impressions:

The package came very well shipped:

I initially fixed the monitor with duct tape to see if I was happy with the position, you can nicely see the 50mm painted edges:

First test:

I think the quality of the monitor at night is amazing:

Even from a steeper angle the backlight is barely visible:

@thejoaovitor cool, thank you. did you leave it at 1080p or did you use 720p? Would you mind sharing your conversion details? I tried 720p and it still did not play very smooth.

@madscientist my experience is that in portrait the performance is almost unusable since everything is copied and rotated and I now decided to go landscape.

@madscientist that is true… good idea, I have one 5V 40mm fan as spare. Just one question, are you using your MM in portrait or landscape mode?

@rak

have you tried this? (#ff0000 just for presentation)

body {
  text-shadow: 1px 1px #ff0000;
}

@madscientist good idea, I will do that as soon as I have the actual glass. I have a passive heatsink installed already and in landscape mode the pi usage is less than 25-30% at the moment

@thejoaovitor very impressive, did you store your webm videos locally? If so how did you get MMM-htmlvideo to play all of those files?

Greetings

@madscientist So, experiment done. This is the result of 24h continues running. You can see the temperature has not quiet stabilized but the trend is well below anything critical. My guess would be that with a glass cover instead of the wooden frame I used to insulate the power dissipation should be even better.

@maros thank you, I really don’t know id it will all work out, I started this for fun as I was reading about the amazing magicmirror2 project and their community. Two days later I am taking apart a brand new monitor… and now I have been constantly working on it on my days off.
