Thought I’d share my build with you guys, I’d like to thank @Zach for his very helpful guide, as I pretty much followed it step by step.

No photos of the build other than the finished product, but it’s a 43" 4K TCL TV as the screen (because the majority of the connections are on the side, not the back) and Pilkington Mirrorpane glass as the front end - for a 43 inch screen, cut to my exact dimensions was $175+tax!! Much cheaper than the twowaymirror.com smart tv glass. I think their glass is Pilkington Mirrorvue which my glass supplier was quoting $215. I preferred the reflection from the Mirrorpane over the Mirrorvue so went for that - the glass company sent me samples free of charge - shout out to Rex Glass in Pittsburgh.

My next step is to get the Facial Recognition module working so it’ll show different items depending on whether it is me or the GF stood in front of the camera, but I can’t seem to get it working with my USB Logitech webcam… I’ll post a help request on that.

Anyway, here it is… thoughts / questions are welcome!

I just tried it, an array works well!!

The glass I’m using has reflectance of 68% and transmission of 11%

Mirror view has reflectance of between 53% and 76% with a transmission of between 20 and 45%

I was just happier with what the Mirropane gave me.

oh and a shout out to @mykle1 for the AfterShip module, probably my favourite one on the screen!!

I’m using MMM-Wunderground for the weather.

there’s a USB and HDMI that go into the TV, it’s more for future proofing rather than anything specific… Then there’s another 2 USB that go into the Pi. I’m working on getting a webcam and facial recognition working so probably use one of them for that.
