Idea Source:
I have a project at hand and need some assistance from the geeks out there. (I hope to return the favour someday...)
If you view the attached image and the video linked, you may get a nice idea about what I am trying to do. I have replaced the coin cell battery with 9v batteries. In the image red lines represent bulbs and the black lines represent the tracks of foil (both positive and negative). All the bulbs are 3v. In the image, in the top part 5 bulbs are connected to 1 9v battery. In the middle, 5 bulbs are connected to 1 9v battery and in the bottom, 6 bulbs are connected to 1 9v battery. The problem is when turned on some lights flicker and some don't turn on (the mount board on which they are placed on is a little curved) when adjusted some light up)(I tried changing the bulbs). Do I need resistors? If yes please tell where should I place them? Thanks for your help in advance...
