Hey fellow NZer, Yup, that's indeed possible, almost ANY motor can be speed controlled, if it's NOT too big, one can simply use a 100/150 Watt Light Dimmer, (the bigger the better) to do so, bigger motors will require a proper speed controller... PWM one...
One can get kits for speed controllers from Jaycar, or **** Smith too, Radio Spares if you have a dollar to spare, they seem to charge like wounded bulls, but their stuff is always available and always works.
I doubt if you would need a microcontroller, as the load is only 65Watts, as it's current draw is under an Amp.
I imagine that the Light Dimmer will suffice... Usually though you need to upgrade the heatsink on the Triac, in any event, by about double, just to be safe.
