While a homebrew ternary computer has little practical use, it’s an awesome example of the, ‘because it’s there’ engineering we’re looking for in a great Hackaday Prize entry.

A South Korean research team has successfully realised an energy-efficient ternary metal-oxide semiconductor on a large-sized wafer. Professor Kyung Rok Kim of UNIST's Electrical & Computer ...

The example in the figure shows an implementation with two ternary inputs, using two of four available analog inputs among the configurable I/O pins of a PIC12F675 microcontroller.
