Dew prevention
OK, I am a cheapskate. I have investigated the cost of dew zappers etc, and didn't like the price much, so got to thinking.
Peltiers are cheap - the most expensive good quality 15/12V one I found locally was $19. Instead of using it to cool, I wonder if placing one NEAR a lens (like the darned finder that ALWAYS fogs/dews up) with the hot side toward the lens in a little cradle would do the trick?
