Introduction: LED Animated Glowing Rapunzel Hair

About: I'm a .Net Developer - an avid Instructables reader. I'm an beginner, but I've got a lot of patience. Thank goodness there is so much information online! I'd like to get eventually get into robots - and who…
Here's a quick video of what the wig looks like in the dark:



I couldn't let one daughter wear a light-up Tron costume for Halloween and not do something for my other daughter. She wanted to be Rapunzel for Halloween.

I used the same circuit as my Tron Disc - the one using the ATTiny45 - please refer to that Instructable for wiring, etc.

Hot Glue was used to hold LEDs in place in the hair - once wired & tested.

A pen with the insides pulled out was used to help run wires through hair. Push pen into hair - feed wires into pen - pull pen out.

Two LEDs were placed at the end of the hair and then one for each braid. The remaining LEDs were placed in the head section.

For the LEDs in the head area - I twisted the leads into a circle, soldered and then sewed into the netting. Make sure to leave plenty of extra wire here! I didn't and it made the net less flexible.

Power was supplied by a re-used 5v Solar Battery. I used a Scoche Solbat II, but any power supply between 4 and 5.5v will work (such as 3xAA batteries).

I've attached the code in case anyone wants it. It also includes a great function I found for a simple random-number generator for the ATTiny.
