In the narrow interval of relative sobriety between my Christmas Holiday and my New Year's Holiday, I've generated not one, but two new letters columns. And there was much rejoicing.

Column #81 has to do with yammering PCs, indoor antennas, sensor sensitivity, faster SATA, headphone power, no-name batteries, bent Gigantas, full moon timing, and acronyms.

Column #82 covers hot CDs, slow 3D cards, iPod toasting, power conditioning, anodes and cathodes, exploding tools, dodgy products, AA lithiums, and Ugg boots.
