Hand-warmer pen

a writing aid for carpal tunnel and poor circulation

I love my light up pen, I click it obsessively to many a store clerks' annoyance. But I wish it would heat up as well. My hands feel cold due to poor circulation. I'm sure a small heating element could be added to the innards of the pen, powered by the batteries.

Halfbakery: Winter Mouse http://www.halfbake...idea/Winter_20Mouse
Includes a link to an outfit that appears to be selling one, although I'm not sure they're for real - they give addresses to send money to, but no price. [jutta, Nov 21 2004]

       Well hello to you too, [Klaatu], and when are you going to fix your email?   

       and furthermore, (hands on hips) just because someone mentions it in an anno, does not make it baked. I googled and can't find a single one, :- P

       Not baked, indeed, but I'll buy the set of pen, mouse, and keyboard when it becomes available.

       That's one of the many things I like about those overprized small "space pens" - they're small and round enough to just keep in my pant pockets, and hence warm to the touch when I use them.

       [norm], was thinking about the mouse too, It would not be hard to add a battery warmer inside. [edit: I see lots of previous discussion on the mouse and mouse pad]

       [dentworth] e-mail now corrected.   

       As cold as it is, this would still be very nice to have.
Klaatu, Nov 21 2004
  

       Nice idea. Heat wouldn't adversely affect the ink quality would it?

       It could dry out a water based ink faster, but donno about other inks.
