Here is a great way to ring in the new year with some friends and technology. It allows you to wire up the fireworks before you start consuming beverages and watch your handy-work when the time is right.
"The Mortars are all on the 16th channel. the "Det" channel. I’ve ran an extension cord out to the street and plugged it into a 12 volt 1 amp power supply. That power supply wire is then frayed and the positive and negative wires are connected to an electronic fuse starter. From there the long fuse is zip tied to all the mortars fuses which will delay them."
