Hi,

I've got a stepper motor that's rated at 9.2V (240mA).  I'm just wondering
how picky these things are about the voltage.  Could I run it off a 9V wall
wart? Unregulated? Should I maybe add an electrolytic?

I'm using an MC3479 to drive the motor.

At the moment I'm using a 15V wall wart into an LM317 set to 9.2V, which
works OK except that the 317 runs pretty warm.

Thanks guys,
Colin
