Bioshock Big Daddy costume
For Halloween, I've been asked to go as a Big Daddy from Bioshock to a party. Going over the top as I normally do for such things, I'd planed on not only making the drill rotate on the arm, but also the eyes light up. While I've wired motors before, I've never done the same with LED's, which lead to some interesting electrical problems. In total, I'd planned on having all 8 eyes wired up with two different sets of LED's, 4 red and 4 yellow per eye. The idea was to have a pack on my waist set up with the power supply and controls. The power supply was going to be 6 9-volt batteries all wired in series (providing 54 volts of power) connected to a push switch. The push switch would be the on/off switch, with the lead going to a toggle switch. The lead would connect to the middle input, the top would lead to the red LED's, and the bottom would lead to the yellow LED's. The LED's were going to be wired in series as well inside their housing, which was going to be cross sections of multiple Sobe bottles with holes drilled through it for the wires to go through. The eyes were all going to be run in series, with resisters at the end of the series before connecting to the power supply again.
1) does the plastic bottle pose any risk of short circuiting the LED's? Electrical tape can always be applied but the question of if it would be a good idea came up.
2) With 54 volts being generated from those 6 nine-volt batteries, what precautions would be recommended to make sure I don't get 50 mA through the heart if something does go wrong?
3) If possible, can anyone suggest a more efficient way of wiring or working the circuit?
