Step 4Now add Power
I played around and found two alternate contact points for the 5V + and -. My goal was to eliminate the circuitry that went to the 5W resistor and heated it up to make the perfume
more effective.
I soldered a battery pack of (4) AA batteries to these connections. Note that I am using rechargables so the total voltage is only 4.8 ( 4 * 1.2V ).
Now, pop the switch once to make it come on. Again to make it cycle slowly, again to make it freeze, and again to turn it off.
I also made one of these and used the 5V from my USB port to run it. With a maximum of 3 LEDs on at a time, the current should remain well under 100ma. It worked nicey.
I also used one in a Halloween prop and it has been running fine turning on/off using relays for several hundred times.
