Hello

I am building an ltd stirling engine which will be able to run off of the heat from someone's hand. I am basing it's finished size on a 140mm displacer piston. I would like to know the...

Hi
Can anyone tell me whether or not a fairly standard optoisolator such as

this one will be able to work as an electrical...

Hi shreifali
They are definitely bipolar stepper motors, just see the datasheet link I previously mentioned.

Hi
I have exactly the same motors and driver board as you do, here is the datasheet for the motors:

(they're 2.3v, 1A, 1.8 degree step with 1.2kg/cm of...

Hi
I have a fairly standard L298/L297 stepper motor driver board that seems to work perfectly except for one thing which I'm wondering if it's normal or not.
When I enable the drive and step the...

Thanks guys that's really helpful, it's just what I needed to know.

Does anyone know if there are any disadvantages from running a 6 wire stepper motor in the half winding bipolar configuration? They're the only type ofbiplar motors with enough power that i can gat...

Thanks Jason Marsha that is very helpful.
But now that I can't use those 1.2kg/cm printer motors I need another source that I can salvage powerful ehough stepper motors from. Another thing, is...

I too have obtained a couple of stepping motors off of a printer and are wondering whether or not they have enough torque to drive the axes of a small cnc mill (small enough to hold a dremel). I...

Hi Don,
I would also like to use salvaged parts from a printer to make a small homemade cnc machine using the driver board and steppers. I have extensively researched the particular chips that are...
