Ok I had to try this, anddddd
Laughing here, I took an old mouse pad, decided this would be fun, and wound #28 magnet wire into a coil that was very loose in the turns, so the turns start at the middle and work out to the edges of the pad. I measured the DC resistance and it was too low for my meter. I am guestimating this to be around 0.01 ohms. I decided to go for a current of 20 mA to see what happened, so knew I would need a series voltage drop to adjust the heating element. From my computer I stole the 5 volts and wired in a 500 ohm rheostat and a 100 ohm resistor to limit this to 50 mA maximum. I adjusted the current flow for 5 mA first and let it sit, and to my surprise, the dang thing was warm and nice and toasty and dang it actually felt good on my heel of my wrist that is always in contact with the pad. THe reason I decided to try it out is that in my telescope days, we would use a bank of resistors to heat the tube to prevent fogging, and all we wanted was a one egree rise over ambient, and running 1 mA current seemed to be fine.
But to the humor of all things, I also will share this with everyone.

Thanks for the Inspiriation JS, next test, 12AX7 mounted inside mouse! :lol:

Ironically, I melted my keyboard just a few days ago. I used two heat lamps, suspended about 5 inches away to dry it after cleaning it. The plastic melted after less than five minutes.IF!!! you are going to heat your mouse, the plastics used to make the standard keyboards and mice are NOT thermal plastics and you may end up with a melted mouse or keyboard.
