Discrete Logic Computers

Commenters debate building logic gates, adders, flip-flops, and minimalist CPUs using unconventional or discrete components like soil pots, resistors, NAND gates, or novel mediums, often referencing Ben Eater-style designs and gate efficiency.

Could this be used to build a super minimalistic Ben Eater style CPU?

Where's your chip that does all that in 1k gates?

How can you make logic gates with this?

Well, there are half and full adders, maybe a flip-flop would be feasible?

Liar. You used NAND gates and a clock.

You can make logical gates from this, right?

You could build one out with discrete logic.

A processor made out of tiny resistors?

So can you make logic gates in this?
