The kit includes a tiny trimpot on the circuit board to vary the pulse width, so I imagine I'll be back at Jaycar to find a substitute variable potentiometer with knob to fit onto the box.....

Mike, I grabbed this kit during their 10% off everything sale, and have it sitting until I have time to make it up, but I spotted the same thing. Please let us know which pot you choose - I don't know whether the trimpot is linear or log - I was going to measure it ..... sometime. Thanks.
