I wanted to buy one of these:http://shop.evilmadscientist.com/productsmenu/tinykitlist/652But I'm not paying $40 shipping for a $35 order.
I am fighting the temptation to add a PIR motion sensor, and add an ISD1820 chip to play some Christmas carol when somebody walks near.

As my wife said, do you hate your family? If I do that for a private copy, I would put a clearly marked off switch on the back. Ah well..... Best not to do it.
