This year I decided to change out the battery pack and wire the Evil Mad Scientist flick light LED boards. You can buy these at http://shop.evilmadscientist.com/productsmenu/89. I soldered the wired from the battery pack to a 3 foot length of 16 gauge wire. I discovered that two AA batters give off 3 volts and I had a 12 volt power supply, so I needed to buy a Car DC Converter Buck Step down Module 12V convert to 3V 3A Power adapter. Since I am using the waterproof power supply to wire 6 flicker LED in the witch jars that need 12v I needed to solder the DC converter and a operate piece of 16 gauge to the output of the power supply. I will connect the DC converter output to the 16 gauge wire connecting the pumpkin LEDs and the other wire from the output of the power supply to the witch jar LEDS. More images to follow.
