building a mirror 101

Everything is relative. Good reflex means bad readability and vice versa. A perfect mirror in the bright living room at noon may not be good for a dark bathroom at night . Someone thinks even a film is his best choice, but another may regards it is a crap with horrible distortion,…
There is no golden rule for this. Every environment and case is different and nobody dare to say the answer.

Try yourself.

@MMRIZE thanks will do. Last question, what’s the spec of the 2 way mirror I should be looking for if I were to buy one? 3mm with 50% reflection?

@1a2a3a If your LCD has enough brightness and good contrast, more reflection(less transmission) will be the better.
The dilemma is this. More it looks like a real mirror, more it will lose readability.
Under the direct strong daylight, Any film or glass cannot help to read small fonts or dimmed color. It will be a nice mirror(but with a little duplexed reflections)
At night in dark room like bath, whatever can show MM nicely. But by condition of handcrafts, the inside of mirror might be shown somehow transparently.(like bezel of panel or wires, your RPI…).

I say again, all the satisfaction is relative. Someone will think it is enough and someone will not regardless of how much good or how much expensive the material is, how much reflexive or how much transmissible it is.

So the glass or film itself might not be so important to someone(and be so to another). It depends on your purpose, where you install, under which light circumstances, which panel you use, and how it constructed with frame, and etc.

Try and find your own answer. And even consider a info board style without mirror also.

And if you ask me,I made 10s MM in several years after knowing this project, I don’t build “mirror” anymore after first 2 builds.

@MMRIZE like you, I haven’t built a mirrored device. I just don’t need another mirror anywhere. the info panel in the hall is perfect.

I thought of one in the master bathroom, but don’t spend much time in there, and nothing is that time critical…

So now I’m facing kinda my own dilemma here. Having uncovered that mirror shall not have background images, my wife is asking for the dashboard version over the mirror because she wanted our baby daughter photo to be in.

I have bought the ikea Ribba glass version for the mirror. But since it’s going dashboard, my issue here is that the glass has to be the same exact size as the monitor. Previously I was working under the impression that if I hide the small lcd behind a bigger mirror that is fine. But if I were to do a dashboard, my glass and lcd has to be the same exact size. My assumption correct?

Actually for dashboard, do people just frame around the lcd or do they use a plastic/glass?

And if so, any advice what I should proceed with next? I’m stuck with the following item:
24 inch monitor
IKEA ribba glass 50x70

Few options came to my mind.

ignore ribba, mount monitor to wall and use monitor as dashboard and call it a day.
custom made a whole new frame and glass/plastic to fit the monitor.
buy a lcd panel that is 50*70 to fit ribba.
put the lcd panel into the ribba glass. The excess putter space cover it with films or use the white cut out that’s included in the ribba.

Hmmmm

@1a2a3a if I am doing dashboard/info panel, I just use a tv.

there is not much module support for touch, and I don’t want fingerprints anyhow.

Save your money and focus on building itself on first try. After first attempt, you can realize what you need really and what is the point of your work. And finally you will realize what to do.(even though it could be, “Ok, I’ll quit now.” :D)

@1a2a3a - One of the modules that I maintain is MMM-WeatherBackground. It will put a background image on your mirror and change it up according to what your weather app forecasts.

I find that the key feature is the ability to set the transparency of the background image. That way you can adjust how much of the background image is present vs the reflection that you see.
