Structure model-testing

Fixing into the Gondola

SOFTWARE LAYOUT

Spark Detection Circuit Update

Added VDD=8V for OA
Added Zener diode 4.7V D3 for OA's LOW output voltage shifting

Project Planning Update

ROBUST shiny metal EXPERIMENT MECHANICAL STRUCTURE

High Voltage Spower Supply Test

input voltage 12 VDC; current drain 250 mA
output voltage 800V
input voltage change +- 2 V => output voltage change +-10V
load 10Mohm => 5V shift
output voltage ripple +-2V
