Welcome aboard pixel lighting.
Guessing that you're on a regular residential block, with all your proposed props reasonably close together.
F16v3 should be all you need based upon your list of props
That said, you may wish to get a differential board (and smart receivers) for the f16v3, so...
just grab a microsd card of decent quality..... unless you're going to put stacks of sequences on it, you can get by with probably a 4Gb one, but probably the best value ones would be the 16Gb ones. :)
As it has been said, use a licenced electrician for all of your mains powered stuff.
That said, people often use an extension cord with the tail cut off and inserted in to the controller box through a gland, and then to your meanwell psu's.
my roofline spacing is 90mm.
seems a long way apart until you realise that my house is more than 100m from the road.
Why 90mm and not 100mm or more ? ..... pixel spacing is normally 100mm, and I can make them fit in to my drilled electrical conduit. :)
primarily the confusion created by having different voltage pixels, and the pixels that don't work when powered on, i.e. 12v pixels on 5v power.... I would imagine they wouldn't even light up at that low voltage ?
however if the OP decides this is how they want to proceed, then all I can...
I think the OP needs to work out which voltage he wants to use across his display, be that 5v or 12v first.
Splitting a display across 5v and 12v can cause it's own issues, and I don't just mean plugging 5v pixels in to 12v supply either ! :)
Meanwell's are great psu's.
That said, if the OP...
My yard is 36 metres wide, and my house is 100+ metres from the road.
I run my mega tree 20 metres from the road, with 50mm pixel spacing. Up on the house I run 90mm pixel spacing.
I also run my lights down the front at 30% and up at the house at 40%.
Like you, the road at the front is your...
YMMV, but I use a HP 1200w psu for my 24 strand, 100 pixel, 180 degree megatree.
Being that you are in the USA, you might find a few HP 750w psu's might work for you.
My tree is running on 6 ports of my f16v3, which means 400 pixels per port. I do PI between 200 and 201 pixels, and run at 30%.
