[old8s]

hi
ok im thinking i can make a rumble pack from an eletric motor and a subwofer amp

sub outlet has reading of 1.2v
i have 12dcv motor
and 12vdc trasformer (pc)

ill need a motor controller i guess
and an idea of how to hook up mosfet t trigger motor controller
i guess this is simple stuff but you never know

anyhow motor only needs to run one direction with big bob wieght lol
guess im building some sort of transducer

any ideas of sites or where to get circit diagrams of how to hook up

am i forgetting somthing
cheers all
