Notes to self…

ilmango minecart station
Apparently the piston under the minecart is "BUD powered", and touching the string will set it off. The sequence of effects triggered that way will also move the minecart, and dispense a new one, which then replaces the old one.

The powered rails seem to have two power sources: the observer on the far right, and the redstone torch. When powered by the observer, the rail power doesn't quite reach the rails under the minecart. As far as I can tell, adding power with the torch won't cause an update, so even though the power should reach the minecart, it won't. Only when the string is updated, the powered rail realizes it should be powered by the redstone torch and activates just long enough for the minecart to be pushed off. The timing of the right part of the contraption seems to be tuned so the powered rails are first depowered, then powered by the observer and then seemlessly powered by the torch again (which also causes a new minecart to be dispensed), so the left-most connected powered rail doesn't receive the power just yet.
