Basically, I feel, that I've gotten good at using electronics in TPT and i want to prove it by making a interesting device . So what i would like from the community is some suggestions on what i'm going to try and make.
What not to suggest: No type of calculators - they make me feel sick. Something that is unrealistic. Something very simple.
Diissaster boolean gates are: AND - if 2 inputs are sparked charges output OR - if one or more inputs is sparked charges output XOR - if 1 input is sparked charges output NOT - if input isnt sparked charges output and combinations of these gates
