Need help here. Yes, I'm crazy. Haven't finished the trooper yet and now taking on a mini Vader. Nothing too fancy for my 3.5 yr old, but better than store bought or rubies
Stopped at radio shack and picked up 2 black project boxes in a 2x3x1 size. Going to be the belt boxes. I also picked up 2 red LEDs with resistor built in. My question is, I ran the red to red and black to black on a 9 volt connector. Lit up just fine. I also ran a little white bulb off it. Was going to mount that inside and just have 2 cutouts with green plexi over the holes. But, I noticed the 9 volt got hot running the two together. Then I realized that the white bulb said 12 volt. Im assuming that's no good and or will burn the battery quick.
If I got a white light that runs 9 volt and still run the two together, am I going to still have this problem? Do I need to run a bigger pack with like multiple double A's?
I also got an on off switch that worked, but I just don't know if I need to just run more juice. Is it bad to have more power/juice like 12 volt battery pack running to a 9 volt led (or two lights)?
