Thank you! I found this page ages ago when trying to find an easy way to
build a step feeder (I've wanted to build one ever since a certain Playful
Penguin thread in rtlToronto), and it inspired me to start a list, but I
couldn't relocate it!

Additionally, he gives lots of examples, including (for at least some of
them) ones he built out of LEGO! For the folks that have asked about Steve's
step feeder, I think he may have based this of a design I built, but I lifted
the idea for a LEGO version from these pages. It's a great resource!
I really need to update and refine my list, put in this (& other) URLs, and
include a "tips & tricks" section. But I'm having too much fun building!

The biggest problem I've had with ball pumps (I've got two sitting above my
fireplace right now) is room below the input hopper "floor". The designs I've
build require a cycling piston below the floor of the input hopper, and that
takes up a good bit of vertical room (when the top of the input bin can only be
9-10 brick heights off the baseplate). I can do it... but the resulting input
bin ends up rather shallow, so I have to make it long to hold a "pulse" of 20-30
balls.
