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 – I – Lightning detector with a simple headphone jack
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.
Part – I – Lightning detector using headphone jack
Part – II – Detecting switching ON/OFF tubelight with a headphone jack
Now in our previous post, we established that the headphone jack can be used to successfully detect electromagnetic disturbances ( Sparks and Lightning ). In this post, we explore the interaction of the tube light with the headphone jack.
Here is a close up of the peak that you saw in the video:
Nowadays of course, we have moved on Non-flickering tubelights and it is highly unlikely that we might be able to detect the peculiar peaks that you see on this. But to be sure we are currently working on this and we will keep you guys posted on the results.
Also if we could incorporate this into a IoT network, things will go crazy!!!
