I've seen this book advertized for a few years now, but never have gotten
it. Anyone have an opinion on it ?

"Easy Step'n", An Introduction to Stepper Motors for the Experimenter"

Thanks.

get a stepper motor (take it out of a disk drive or printer)

look up stepper motors with Google,

and you will have tons of fun discovering for yourself
how they work.

Except that if you actually want to use stepper motors and get the most
out of them, there are some special considerations that need to be made.

It's not immediately evident to an amateur what the difference is
between a resistive and a chopper drive. Or how to calculate torque and
max speed for a stepper based on coil resistance, inductance, supply
voltage, and drive method. Or what the benefits are of different coil
schemes.

Such things can result in a difference of a few cents in a design, but
twenty times the performance of a "guesstimated" solution.

Been there, done that, and will be doing it repeatedly.

But have you read the book? Got any opinions on the "Easy Step'n" book ?

Thanks!
