Ok, i purchased the IRL540 transistor and the magnet worked... problem was it did not drop the ball when at the full half turn... it held the ball until back at the start position then it let it go... tried to use moon magnet again but fuse has blown... not sure if the ball was released by the moon magnet or the fuse blowing... installed a new fuse and it blew straight away.... its like the IRL540 was working fine but when told to power the moon has stuck on so maybe a part before the magnet driver board is bad.... any ideas???
is this the diagram for this circuit?
