I'm curious what you consider a "logic" gate?  Do transistors count?

Transistors are used to build them.  If you are using a transistor to accomplish computational work, yes, it's a logic gate. A slide rule is a logic gate. That something is a logic gate depends upon it's ability to model functions and it's use to that end.

Logic gates are primarily implemented using diodes or transistors acting as electronic switches, but can also be constructed using vacuum tubes, electromagnetic relays (relay logic), fluidic logic, pneumatic logic, optics, molecules, or even mechanical elements. With amplification, logic gates can be cascaded in the same way that Boolean functions can be composed, allowing the construction of a physical model of all of Boolean logic, and therefore, all of the algorithms and  that can be described with Boolean logic.

Maybe it's about time I did?

Given your interest, yah, probably. Bit like a programmer deciding to learn about hardware and it's manufacture. Your model will -have- to conform to the kind of system the hardware can support, or else it couldn't be representative of a human mind even if it was a comp mind. Presumably, if comp is mind...it can be accomplished many ways, but the different manners in which it's accomplished, separate hardware, would lead to noticeable different types of systems with different ranges of ability and different limitations. It's possible, for example, that you can model an NN or circuit that our bodies just can't build..or that even if they did, due to our anatomy, they wouldn't/couldn't work.
