How it works

What this project is testing.

This project sits in the same dangerous high-voltage family, with the interesting science in the conversion and discharge rather than the wearable form.

It demonstrates how salvage electronics can create large potentials, how air gaps turn into sparks, and why high-voltage experiments need distance and containment.

\frac{V _{s}}{V _{p}} \approx \frac{N _{s}}{N _{p}}

Step-up systems trade winding ratio for higher voltage.

V_{b r e ak d o w n} \approx E_{b r e ak d o w n} d

A larger gap needs a larger voltage before air conducts.
