Step 8: Last Details! (Optional) (LEDS)

Depending of the helmet you're making, you can weather the painting, or in my case, I added the LED lights in the helmet!              

Here's a video of the LEDs:
 
For those interested in the electronics things, I simply used a 555 timer and a 4017 decade counter to drive 16 leds boards with 4 leds each, and two more differents boards, with 8 leds each, and two other boards that are not connected to the 555 circuit, but still, have 4 leds each, with ~90 leds in total! Everythings runs out of 8 AA batteries (12v)
