Use a 9Volt DC wallwart power supply with the ArduiNIX (Not included) Once plugged in, certain portions of the ArduiNIX will become charged with high voltage. Do not touch the anode pins, or test points, or any exposed solder points while the unit is charged.

To drive VFD Tubes in the 30 to 40 voltage range, the timing capacitors in steps 6 and 7 must be changed to higher value capacitors.
