Hello to all from the other side of the equator,
boy is it cold here!! and raining!!!
i am in the process of building an eyepiece/accessory box. what i would like to do is install several red lights for illumination. however, the only thing i know about DC systems is how to wire a trailer. i feel i could build whatever i need, i just have zero education towards capacitors, resistors, and the like. also i would like to make several dew heaters.
a vehicle is not always an option so i'll need some portable power, the lighter the better.
as for the lights i would like to use as small a battery as possible. preferably one which is incorporated into the box itself. i have room for a nine volt (one of those bigger ones with the springy things on top) or smaller. would this be sufficiant? also a dimmer switch would be nice.
could this power source also be used to fuel dew heaters(eyepiece,telrad,mirror,ect. )? and what kind of life span could i expect?
thanks in advance for all advice.
