So, we had the opportunity to test out the headphone jack with an actual spark gap and it was absolutely wonderful. Check it out:
With the data we can actualy find out the frequency of the spark occurrence. In our case it turned out to be ~ 34 – 36 Hz. And since this is in the Audible range we can actually hear this (somehow we missed this when making the video)

Part – II – Detecting switching ON/OFF of Tube Light using headphone jack
Part – III – Cigarette lighter spark detection using headphone jack
This is part-III of the post series on detecting electromagnetic waves using headphone jack. In this we capture the EMW that emanate from the spark gap junction on a lighter. This is analogous to our gas lighter experiment but conducted at a smaller scale.
We say that this is analogous to the Gas lighter experiment because the waveforms obtained are extremely similar in nature.
