For the homeowner who didn't know he needed one

A FLIR (Forward Looking Infrared) camera. For your smartphone or as a stand-alone unit. ZDNet discusses their uses, which include to obvious: detecting energy leaks from appliance doors, the location of wires behind walls and ceilings, where that raccoon is in your attic, or your wife's lover in the bedroom - under the bed or in the closet? - to the less intuitive, like where a plumbing stoppage is, and - I like this one - swiping passcode from ATM machines by scanning for residual fingertip heat on the keypad.

FLIR Instruments has an informative website, including reviews by actual users (and some other really cool products, ranging from night vision scopes for hunters to nav systems) but you can also find the things on Amazon. Price seems to run between $299 -$699, depending on features, but it's nearly Christmas, you're running out of ideas and with two-day shipping ....

And for a stocking stuffer that, again, happy hubby didn't know he needed, how about a Carp Calendar, available from Amazon for just $18.95? It's German, but the pictures should be translatable: I know Walt could do it.
