FWIW If you take a cheap digital analog clock, remove the battery, connect to the two coil connections, you can drive the clock with a 0.5 Hz square wave through the series combination of a capacitor and resistor. Typical values are 100mfd and 200 ohms. You need to select these values to get certain stepping without pole-ing. The clock originally used 1.2 volt pulses, alternate polarity about 20 mS long. You can trade off these values and still get smooth certain operation.
