hi there.. hmm. i'm not sure... whats that "4.5VDC 100mA converter"?
heh heh if you were to go by the FLED solar engine i made before.., i think
yours does work... but why does it twitch... perhaps its due to the motor
itself?
the CD motor.. are you talking about the one that drives the lens assembly
around?
