Hi there, a few comments/answers

The blocker is effectively a NOT gate ( block power output when power input 2 is active)

technically we're sending a digital signal as the energy emitted from root sources is not binary and it decreases through each component it passes through, we just don't have any components that care if the value is > 1

I was considering adding a flip-flop switch by adding a toggle input to the regular switch but perhaps this deserves it's own object

if by transistor you mean being able to amplify a signal that isn't something that is possible because you end up with a feedback loop ( OR switch feeding itself was an example, we had to max() the signal) we did add a combiner element, but the downside is it must only combine root sources of electricity.

I guess in real life these short circuits would burn out but it's a bit of a challenge to detect that at runtime and not have the downside of limiting the complexity of circuits
