Connect long wire antenna to center top where AC Source input is located. If near strong RF sources you get more power.
All diodes are 1N4148's.
220 nF capacitors are 100 volt Mylars.
33 uF. capacitors are 25 volt electrolytic.
Note video demo below points to need to observe correct polarity on capacitors.
