When solving challenge 64, the voltage tripler, I came up with a solution that is slightly different, and seemingly more simple, than the one listed in the back of the book. I think it’s still valid, but as the output of the circuit is the sound emitted by the ammeter, it’s difficult to verify it.
To do so, I used the simulator to build my circuit so I could compare the sound with the one from the simulated proposed solution. I think they do emit the same sound, but again I’m not 100% sure.
So I wanted to ask: is this circuit I built a voltage tripler?
Bonus question: I built that circuit from this diagram. Is it correct?
