I went to do this sort of thing the other day. First thing I did was try and find a Pi Zero 2 W. Discovered most models of Raspberry Pi are completely unavailable. And so, another side project was canned.

That has been the situation ever since the worldwide chip shortage hit. Raspberry Pi (the company) decided to prioritize companies that use Raspberry Pi's in their products over consumers. So it became almost impossible to get a Raspberry Pi, unless you were willing to pay a huge markup to a scalper.

The situation should improve this year though.

> As a result, we can say with confidence that, after a lean first quarter, we expect supply to recover to pre-pandemic levels in the second quarter of 2023, and to be unlimited in the second half of the year.

This is all great but don't underestimate these mirror displays: A friend built a similar one and disabled it when he saw the energy consumption. And this was a few years back. Still waiting to pull the trigger on an appropriate e-paper display. At least I'd suggest to measure the setup before you commit to the whole crafts project.

I don't think an e-paper display would work in this case, though? The nature of two way mirrors requires that the screen actually emits light (instead of just reflecting it) for it to come through.

Maybe an OLED panel would do the trick though, since most of the screen will be turned off. Probably much more expensive to get one of those, though.

It's not entirely their fault. The Raspberry Pi foundation has very close ties to Broadcom, who make all of their CPU SoC's. The original Pi was made with super cheap chips Broadcom was struggling to sell to anyone else. Either a batch of SoC's that didn't sell as well as expected, and later fabrication capacity reserved at a foundry that it later turned out wasn't needed.

The Pi foundation basically sucks up overproduction of chips from Broadcom, in return for low prices. But when there is a chip shortage and no overproduction, they don't get any.

As it's not mentioned yet: https://rpilocator.com/ might help getting a Pi at its intended price.

How are there exactly zero photos showing how slim this thing is/isn't!?!

EDIT: In other news, the settings menu of Pi Imager is brilliant. It automagically fills in your RSA public key, your WiFi details, and other time-saving details. I can't believe how hard we had to fight the RPi devs to make the feature usable and stop hiding it behind a weird keypress combo (to the point we released a fork). They were obsessed the extra options in there would confuse newcomers too much. Those devs were weirdly condescending and really hard to work with, I won't bother again.

They link to the display to use on Amazon. It's very thin at 1 cm.
