The aim of this project is to build a hand cranked Marx Generator for display purposes. Where someone can wind a handle a few times and a loud bright snap of lightning ~10cm long accompanied with a cascade of 20 smaller spark gaps flashes at the same time.
An interactive, dangerous and loud electricity display.
A Marx Generator is a very simple and old circuit first described by Erwin Otto Marx in 1924. It generates a very high-voltage by charging a cascade of capacitors wired in parallel, then suddenly connecting them in series using spark gaps. Air breaks down at about 30kV/cm depending on humidity and temperature and when the arc forms it is virtually a short circuit and this is used to join the capacitor in series.
The project part list so far
High voltage Invertor 15KV DC
First rough test of spark cap and RC combo
Second rough test of 2 stages in the correct circuit configuration
