Has anyone tried running their 9v train set off of the rcx? I did it over
thanksgiving with limited success. At full power out of the rcx, the train
moved only about 1/2 speed (rcx 1.0 plugged into the lego train's ac
wallwart). I haven't measured yet, but I'm guessing that either the riostat
that runs the train provides a few more volts output at full speed or the
rcx limits the current to the output port. Does anyone know what the
electric 9v train motor draws at full speed and what the rcx outputs are
capable of contributing. I was hoping for lots of interesting programmed
train layout fun, but I think I will need to work on either a rcx controlled
relay system or else a mechanical device that physically turns the train
riostat under rcx control before I get too excited.
Many thanks.
