...and if your lawyer knows something about electrical things as well, you'll be laughing:)

The problem here is that a simple linear PSU is about a simple an electrical circuit as you can get, but the consequences of getting it wrong are serious. Get a proximity switch or BOB-to-driver wiring wrong, and you're unlikely to do anything much more serious than pop a fuse or give yourself a serious bit of head-scratching to do. Get mains wiring wrong and fatal shock or significant fire hazard are possible. In principle, it should be easy to describe but I wouldn't like to explain how to identify the wiring on a toroidal transformer with twin 110/220V primary windings. If you understand it, then you don't need the explanation and if you need the explanation, then you probably shouldn't try it! Which leaves the question about how you do learn through experience, and Jazz's suggestion that it needs a private one-one conversation that can be tailored to exactly your set of components, not some bunch of kit that someone else might buy randomly from eBay, is the way to go.
