Rodini pulse charger with Rodin coil,555 timer, and single diode charge circuit. It is a good charger for its size. It charges 1000 ufd / 200v capacitors up to 120 VDC in a few minutes, using only a +15 volt DC supply. It may also be a good battery charger, using the Bedini-type collapsing B-field spike effect common to his SSG circuits . I'm doing more testing. The Rodin coil also spins up a Neodymium ball to a moderately high RPMs with plenty of peripheral magnetic fields all around the coil.
Unsure if the spining ball makes the charging function better or worse.
Thanks to experimenters like Jaimie Buturff, lidmotor, neomatrix11, geminitrix, johnydavro and others for posting their work also.
IMPORTANT NOTE: Error in 555 hookup shown on the diagram. 555 Pin 7 should connect between the 1K resistor and the 100k pot. The top of the 1K resistor connects to +15V supply. My apologies for that.
