The simplest strobe

Good day to all. Due to the fact that modern cars they don’t really need a strobe to adjust the ignition, the need for it has not yet completely disappeared. First of all, because there are such cars, and secondly, not every car owner knows that the high-voltage cap cannot be removed to check the spark on modern ignition systems, as this can lead to failure of the high-voltage coil. Which in turn is worth a lot. For this reason, I set out to make a budget and reliable strobe.

And also if we connect the simplest multivibrator to the control electrode, we get excellent light accompaniment to the music.
