Here we sould need a solid stock of experimental material, otherwise the stuff will become a dry dusty desert. And the area has to be clearly furthermore. But it is a good way to play with the inverters, the ANDs the ORs the XORs and their inversions.
It is now time for the question how many different types of gates with two inputs and one output might be possible...
The logical answer to it will puzzle even the discoverer! And after that the astonishing feat that each of these 16 functions can be achieved by combining e.g. NAND gates and inverters or as well NOR gates and inverters
