Logic gate elements
-
To be fair, that isn't much of a tutorial. The closest to a tutorial here, hidden deep within the wiki, is https://powdertoy.co.uk/Wiki/W/Complete_Electronics_Tutorial.html, but even that is very outdated. The wiki doesn't mention anywhere even that BRAY (as opposed to PHOT) can be used for logic, let alone anything about subframe (which, by the way, is 2 years old).
I would make a more current Powder Toy logic tutorial, but it feels that there just isn't enough demand for one for it to be worth making one (prove me wrong). Making a good tutorial takes a lot of effort, especially when you include screenshots and frame animations.
Anyway for the original topic, @EaterOfCake try imagining how single-bit logic gate elements could allow you to do any better than present adders (hint: they can't):

Okay, after giving it some thought, I came up with this:
What I said before is just plain wrong. I now agree that most logic gate elements would be pointless, with one exception: the NOT gate. These things are an absolute pain to make, so how's this for "elegant implementation": A power source that turns off when powered with PSCN. It would obviously not power PSCN, but would power all other conductive elements.
By the way, forget the other ideas.
PS: I use too many colons, I know.

FILT also has a NOT mode :P a 29-bit one.
