[Lab] Help choosing a stepper motor

As a non-technical person my suggestion may be way off base, but perhaps
working with the guts of a scanner would fit the bill. Motor and belt
already to go.

No, the stepper motor is going to drive a pulley to rotate a platform

Does the mass need to be lifted against gravity?

The mass isn't very heavy (probably 500g) and I don't need the resolution of
something like a cnc or 3d printer motor and speed isn't super important

The easy driver is for bipolar only, it's a good choice for small steppers

There are many choices on eBay as well, about $11 will get you a serious CNC
driver for larger steppers (NEMA23).

What resolution and speed are you looking to achieve? 

The mass you are rotating, is it heavy and will you require fast start and

Hey all,

I'm pretty new to electronics and I'm having trouble choosing a stepper
motor for a project I'm working on.

I'm ordering from robot shotp, and it looks like this EasyDriver board
will let me control whichever motor I end up choosing, but the number of
motors on robotshop is pretty intimidating.

I'm going to be spinning a small platform so I don't need a lot of
power. Basically, I'm wondering whether I need a bipolar or unipolar
motor? What kind of voltage? Amperage? Any help would be appreciated
