Hi All,

Is there a secret to getting the picaxe to power a pager motor, for example, one capable of swinging a small drumstick?

I'm working with 3 GM10s. 2 for the wheels via the L239D, and one for a "percussion actuator". The percussion actuator's not working for the controller:

The Setup:

1 gm10 wire connected to pin 4

1 gm10 wire connected to 0v

5.5 V single power supply

ANY combination of Darlington / no darlington / 330 ohm resistor / motor driver in or out

The Code:

high 4

I've ordered th GM10 geared minimotor from solarbotics.

I know some of you have used it before.

Mine haven't arrived yet, so I'm still dreaming about it.

Here's a quick question for those who know it;

How big a wheel can I connect directly to the output shaft on the GM10 without any significant loss of power. I see they ship it with an optional 25mm wheel, is that the biggest recommended diameter, or can I go bigger without gearing it down further?
