A new hope: Epoxy granite and steel.

Power supply

I've seen a toroidal PSU is a popular choice. I've also read that it can be quite dangerous to work with, as in getting electrocuted. I have octopus fingers, they get into all sorts of places without my permission, which usually results in cuts and wounds, I'd rather avoid any potential dangers, I'm quite clumsy in general. What are my options here?

AC/DC

I'm also confused about the fact that these (eg. https://www.cnc4pc.com/unregulated-l...oidal-psu.html) output DC, if I got AC servos, how does that work? Do I convert it back to AC?

Thanks!
