Okey, lets look at the costs,
mirror glass 1.6x1m will cost ju about 180-300 euro depending on what type you choose.
55" OLED TV (55" would fill most of the size and OLED will work better for a smartMirror due to the contrast and pure black). 1700-2000 euro
the software (from mirror me booth) is 3100 euro
then we have the computer, probably to much for a raspberry, so you need a intel/amd machine
for about say 200-300eur as a minimum.
Then some other hardware as camera, probably 50eur
If you want it to be touch the cheapest way is IR-frame on around the mirror around 300eur,
running touch foil will set you back around 400eur
180+1700+3100+200+50+300 = 5530 Eur and that’s only the most essential parts,
Don’t get me wrong, I would also build my own, just saying that in the end it rarely get cheaper financially by doing it yourself.
