Can somebody verify that I'm on the right path for a 24x36 Magic Mirror?

I’m based in the USA and I’m in the process of planning out my first build, and it’s turning out to be more expensive than I originally thought it would be. I’m fine with the technical side of the project, but I’m not very good when it comes to building out an actual frame.

Planning for a basic kitchen magic mirror that will use some default modules. Doesn’t need touchscreen or anything, but I’m open to it if it’s an easy addition. Would also like to add some sort of presence sensor but not sure how to build that out.

Here is what I am currently planning:

24 x 36 30% Transparent Acrylic Mirror: $89
32 Inch Monitor (I read that VA panels have better black levels so decided for this one): $271
Raspberry Pi 4 Starter Kit: $119
Budget for a Frame: ~$200

Total: $700+ after tax

Does this seem high? Do these components seem correct? I’m struggling to find the right list of things I’d need to purchase for this project.

Thanks to anybody who can help in advance!

@poopflavoredcake do you NEED a ‘mirror’ in the kitchen?

I keep trying to justify adding a mirror surface in the hall where my mirror system runs.
it’s a 43in TV. was a 24, then went to 32, now 43 HD.

I like the size for the content and the crispness of the image displays. but I can’t imagine any additional value to seeing me reflected in its surface.

I wanted touch screen, but hate the idea of fingerprints. I see them on my laptop and phone. and not much MagicMirror stuff is touch enabled anyhow.

I use a Webcam for motion detection. didn’t have a pir sensor at the time

the acrylic panels have a tendency to flex. it’s amazing how it shows.

so, my advice, find a used 32in tv, build the system w the parts.pi, detection sensor, modules. try it out.

many monitors do not turn off by command. you turn off the hdmi port, and get a big no input display, as required by the EnergyStar standards. my TV is like that. all I can do is hide all the modules. it’s my hall nightlight.

oh, and figure out how you are going to get power there. I ended up putting an outlet in the wall, and connecting it to the circuit for the attic light.

One more vote.

32 Inch Monitor (I read that VA panels have better black levels so decided for this one): $271

Wow, the monitor itself looks really good. But in my opinion, it’s somehow overkill. Generally, MM and your Pi don’t need such a high spec: 165Hz, 1ms, … MM is not game machine or Netflix player.
And if you really assemble Spymirror on your screen, you may lose some of the benefits of those high-class monitors.

A bigger screen would be heavier. It needs more robust frames and mounting methods, and thermal control must also be considered for that kind of monster.

Even though RPI 4 can handle up to 4K60p (3840x2160), It would be a burden for RPI4. If you are considering playing clips on your MM, you may need a stronger device.

So, what is your purpose? Your types of equipment would depend on your needs.
