I'm interested in mimicking the functionality of the Arqball Spin, at $60 it isn't cheap so I'd like to make the most out of my Mindstorms parts.

I'd like to use NXT-G to program a motor to rotate 350° in 20 seconds. NXT-G can only controll the power of the motor and duration (Unlimited, Degrees, Rotations & Seconds). The power of the motor can be set from 0 to 100 seemingly arbitrary values:

enter image description here

I don't mind using 3rd party software to program the motor, provided it's easy to use.

Do you have access to the Rotation Sensor at all? You might be able to do some internal calibration prior to the main run? – Zhaph - Ben Duguid♦ Jul 24 '12 at 11:15

@Zhaph-BenDuguid Yes, I do, but it hasn't helped much. My motor is weak at low power (4-12-ish), it would turn at a reliable speed so I increased the power of the motor and added a small gear to power a larger one. – Ambo100♦ Jul 25 '12 at 20:24
