Is it possible to build logic gates (at least only OR, AND gates) by just using electric wires and resistors with no semi conductors (no diodes, no transistor or any other semi conductor material or device)?
The reason I'm asking this is paper circuits, by using only graphite pencil (graphite pencil lead contains some amount of graphene which is semiconductor but not a detail to focus since its in minimal amounts and don't affect it) and paper (recreating electronic components to some extent, and to try to challenge myself) making capacitors, resistors are simple but what about logic gates.
So I thought something like this, a power source that only supplies a consistent current (even if its shorted) e.g.: bench supply.
- drawing 2 lines connecting them together somewhere before the output.
- making output on end and to have higher resistance by drawing paper faintly, less current can pass due less graphite = less conductive.
- electricity takes shortest path that does have less resistance.
if a: false b:true then current going to rush through a and return to supply no electricity passing also due everything connected it should affect the output, output should be negative after this point.
Will something like this work? Here is thing susposted to drawn to paper.
I know this is short circuit technically but as stated earlier using a source that supplies fixed amount of current. By doing that at least its not going to burn or destroy the supply. I revised it a bit.
