Subject: bicore


Hello again

i'm having great trouble trying to build a wlker using Ian Bernstien's
tutorial on how to freeform the bicore from beam online. He says that if u
r using the 74AC240 then u should be able to drive a motor directly, well
i've tried this but it does not seem to work. So has any1 else used this
tutorial and had any success?? If u have then please can i have some tips.

Does anyone know wot voltage this bicore needs to run a little motor ( 3v,
300ma) - mayB this is my problem, the motor??

Do i need to use a h-bridge if my motor is running at over 100ma??
thanks

si lord
