Step 4Wrap up...
The first generation hats were 20 LED strings with 4 AA batteries. The LED's were smaller, but they were bright, and the lens was a clear lens so they had a lot of sparkle. They were either all on or all flash.
I have made a couple hats with 2 strands, white in the ruff, and red/green on the top part of the hat. I carefully cut the power leads on one of the strands and soldered back into the battery case of the 2nd strand so I can power both strands from one battery case. This lets me control both sets of lights independantly, so I can have the white on, and the red/green flash, or whatever.
For even something even more complicated, I took the power leads of the second string, and added to the first string after the flash circuit. So the second string would only get power when the first string was set to on or flashing. This made the second string have an interesting strobing effect.
Enjoy!
