WS2812's don't have to be part of a strip. They come as single element modules as well.

how the data is sends to each single LED/element ?
edit: must be a connection between each LED somehow isn't it?

Why use a compromised approach if a better alternative is cheaply available? Suitable mosfets for this purpose are cheap. Even bss123 or 2n7000 would do nicely and they're a dime a dozen - quite literally.

Is just because all the project was last minute and I could not buy any other transistors so I was forced to use what I had at home .
