Tiny SMD Cockcroft-Walton generator

I decided to build tiny and scalable SMD Cockcroft--Walton generator when discovered that local store sells SMD 1000V x 0.1 uF capacitors and 1000V x 1A diodes. One board is 45x35 mm and can be stacked (vertically) with same boards. It has 10 capacitors, so output of one board can be as high as ~500V x 10 = 5000V In this video it is connected to little inverter I built to generate high voltage from 9V battery, but it also works well with standard AC power suppy (220V in my country).
