Here's the problem - I need two pistons to go at the exact same time, so that one of them is contracted and the other is expanded, on a switch mechanism. To achieve this, one of the pistons has to have an inverted redstone signal, like so.
This would be all fine and dandy except that when the signal is inverted it's slower by the tiniest fraction of a second. So, I add a repeater onto the other piston to slow the signal, but then that one is slower than the other. This problem has stumped me on many of my redstone projects, and any solution would be much appreciated.
