  1. I know from experience that GST is applied and is payable once the goods arrive in the country, before they are delivered. Apart from GST, and pehaps a small customs charge, delivery was the only other major cost.

    Paul, is the 64 off based on the minimum order quantity for Mouser? I notice the next price break at 100 off is US$1.50 = AUD$2.73

    I'm thinking about the quantity that I will want..

    thanks

  2. Adjusting the pulse width is ideal for controlling brightness dynamically with a digital circuit, as Thorsten says. If the "controlling circuit" is an analog waveform generator(eg LFO) then the brightness of the led will be proportional to the LED current. This is easily measured by looking at the voltage across the LEDs series resistor.

    For a standard LED the voltage source must be above 1.2V before any current will flow above this brightness and voltage will be quite linear.

    questions welcome. ??? -> :D
