Hey all. Ive got a costume party coming up in 2 weeks and im planning on going as Iron Man
Now im looking at buying some LEDs so i can replicate the Arc reactor from the chest. I was wondering whether i can solder the LEDs directly to the batteries or whether i need to have resistors/cables between the batteries and the LEDs. Any advice?
The resistors that are pre-soldered are sized for a 12V supply so you can use 8AAs or a 9V(this would work but the LEDs would be dimmer). You might also consider picking up a simple switch from Radio Shack or somewhere so you can turn them on and off. Fell free to ask more questions if you need help.
