Why not use the onboard WiFi adapter on the Raspberry Pi3 B ?
On the sensor topic . Why not go with a Microwave Sensor. Search posts by @fozzie as he has just installed one and likes it alot!
I searched for the thread for you and here it is https://forum.magicmirror.builders/topic/11704/update-replaced-my-pir-sensor-with-a-doppler-microwave-sensor/12
Unfortunately, that is not going to work for you unless you then apply “2-way” mirror film or reflective coating. The operative word is “2-way”. Standard mirrors won’t work. Frankly, you’d have one hell of a time and still not be satisfied. If cost is an issue then please consider “2-way” acrylic mirror which is far less expensive than 2-way glass. Of course, glass is the best result but acrylic can be acceptable. You get what you pay for.
Do a search right here on the forum for “which mirror to use” and you’ll find plenty of discussions about it.
How to rotate a display on Rasp Pi… Unless you’re not using a Rasp Pi
As for calibration you should check with manufacturer… I am using a 32" TV with an IR frame so it covers 100% and no calibration was needed.
Any screen should work, as long as it’s well against the glass it should be fine.
As for the mirror glass, 70% reflective/30% passthrough seems to be the norm for “Smart mirror glass”… it goes by different names and such from manufacturers.
After weeks of research and a first model that you can see on my website https://www.votrehistoireenimage.fr/
I try to change my mirror which I am not too satisfied. I used the Mirropane Chrome Spy 6 mm
And I read everywhere that it will use mirroview in 75/20
I am looking for suppliers who deliver in France and at reasonable prices
Thanks for your help
The pi3 runs hotter than the pi2 (as the pi4 runs hotter than the pi3), it’ because of higher clocks and there fore more power usage that results in higher temps. The RAM issues I can’t explain however. (My Pi3+ runs at around 45-50C with a heatsink on the cpu.)
The Raspberry Pi 3's average SoC temperature unader load was 61C with a peak of 82C. Meanwhile, the Raspberry Pi 2 had an average temperature of 48.9C and a peak of 59.C
Another reference :
I have one mirror glass to offer which I don’t have a use for anymore.
Model: Pilkington Mirropane ChromeSpy 4mm
Size: 500 x 500 mm
It cost me 82€, I’d sell it for 60 € + shipping.
I live in Germany close to Duisburg so pickup is of course possible as well.
Let me know if you’re interested.
@thisistheplace Thank you, this is sound advice. I’ll give your suggestions a try after rescuing the bezel from the rubbish bins failing that, I’m guessing a cheap Chinese control board is the only option left to try. Thank you again for your time and help
Frameless mirrors/floating mirrors are hard to do when you have to hide a screen and possibly a pi/other hardware. (And you probably want polished edges for that to)
If you are able to build the screen and pi in to the wall itself and then mount the mirror flush on the wall, that would be one way of doing it.
But since your glass won’t cover the entire screen (being 1.1 inch to short) the best thing to do is to build a frame with a larger bezel around the mirror+screen.
And in that case yes, cutting the glass down would be good (just to get closer to the screens image ratio).
With a larger bezel you can hide the overflow and you won’t get a backlight-edge visible on your mirror (since all the visible mirror surface will have the screen behind it).
You could probably find a ready made picture frame that is close to your measurements, and then just build a simple wooden box around the components that you can mount the frame to and in the same time get mounting to hang it on a wall.
(something like this maybe : https://www.amazon.co.uk/14x10-PICTURE-PHOTO-FRAME-Black/dp/B00BTBGGFC)
You don’t need any specialized tools to make a frame (a saw, a hammer, some tiny nails, wood glue and some wood.)
I’m working on that same display. I’m mostly changing all the default module regions to center_middle. I’m running MMM-pages to show only one module at a time in that area. I have a navigation module I wrote for that screen to navigate prev/next and a home button to go to the default (first loaded module in MMM-Page modules config) module. The navigation module is on the bottom_bar region.
