    Dick Smith Electronics has a kit to make one - K7217, but it's considerably more expensive - $127. The project was published in Silicon Chip magazine in the July/August 2004 editions.

    Cheers for the kit - anyone aware of a pre-made "consumer" model I can pick up from a store ;)

    I'll look into the Dick Smith Electronics kit :D

    P.S. What does "Adjustment of brownout voltage threshold" mean? Brownout?

    In a blackout, all power is lost, in a brownout, the voltage drops significantly - which can cause damage to electical appliances (especially electric motors).

    Im going to assume that the 'Adjustment of brownout voltage threshold' gives it the abilty to cut power during a brownout.

    Yes, kamehameha is correct. Paraphrasing the SC article, the threshold adjustment allows you to set the voltage level at which switch off occurs. There are also settings for number of sag cycles so that momentary dips don't cause false triggering and delay before reconnection to allow refrigerators to stabilise if the interruption occurred during a cooling cycle.
