High voltage is fun. But also incredibly dangerous. This circuit creates so many ions that everything else becomes charged. Be careful or you may zap your chips through excess charge or you'll shock yourself.
If you touch the high voltage wires you will most likely die. ONLY BUILD WITH FRIENDS (So they can call 9-1-1 when your heart stops) WITH SEASONED ENGINEERS/VETERANS, AND ABOVE ALL ELSE JUST BE SAFE.
If you are smart about this project it is no more dangerous then mains electricity. Please handle with care.
