I made a battery operated fan to run inside my cigar humidor to circulate the air and maintain the humidity level. I am using a 1.5v dc motor with one D cell battery and a 10 Ohm resistor on the positive lead to slow it down a bit. I thought the resistor would help conserve the battery since it runs constantly. I'm not sure if this will help since I've read that resistors just drain energy in the form of heat. To remedy this, I would like to make a timer circuit that will run the motor (without the resistor) for 5 minutes on and 15 minutes off. I would really appreciate any help in the making of this circuit. I have a Radio Shack nearby, and that's what I have to work with for now. Thank you in advance for your help. I threw in a few pictures to give you an idea of what I'm doing.
