Yeah, we have pictures of each step and explained polarity at the top of the page, and then mentioned whether each part was polarized in each step, but the silkscreen for the resonator has a notch on it.
I can see how that can be confusing, so I added a sentence about it in the step.
We most certainly modeled our build instructions after ladyada's, and followed most of her presentation on making a "kitbiz." I personally feel like her kits could use more explanation discussion around the theory, although her newer kits have been much better about this. Matthew made some excellent visuals in the "Design" section for the TM.
