This wig is just one part of a costume a friend and I made for a school festival.
In case you can't tell we were Alien Dandelion-Babies.
The eye-lashes, makeup and the hover-board (not pictured) will get their own 'ibles, which I will link to once I have made them.

My aim with these wigs was to make something that people would just come up to and pet.
Personal space? No.
Awesome? Yes.

The wig is very simple in theory but a little fiddly to construct, so it might take some patience. I suggest having a podcast on.

The wig was inspired by The Seed Cathedral designed by Thomas Heatherwick for the 2010 World Expo.

Step 2: Speperating the Fiber Optics

Having pulled apart my mood lamp I took small bunches of the fiber optics and held them together with a rubber band. This makes them easier to work with later.
Make sure you don't have fiber optics in a bunch that come from areas that are too far away from each other. This tends to almost weave the fibers together at the base and make them difficult to thread through the wig.

I used small bands intended for braces. To hold the bunches together I made what is apparently called a "Larks head knot" (see picture) and then rolled it down the bunch which meant it secured itself, somehow.

Lady Gaga has a fiber optic wig too.  I think yours is better.

3 blue LED at around 3 - 3.5 V each and I assume 20mA;
3 AA batteries -> 4.5 V;
4.5 - 3 = 1.5 V;
1.5V / 0.02A = 75 ohm (1/4 W is more than OK);

So each LED in series with a resistor, and then all three LED-resistor in paralel

Sounds about right.
My LEDs were white and I believe were closer to 4 V, which is probably why I escaped without harm.
Or I just had a battery pack so dodgy it provided its own resistance, which is very possible.

No resistors on LED?
TheTatterdemalion (author)  ASG_81 year ago
I don't think so. But I might be the exception because the battery pack I used had also been the light source for the lamp. It had 3 LEDs connected originally (I took them off because they were bad colours) so I knew it was safe for that number.
More batteries or fewer LEDs and I don't know. A resistor might be a good idea, it's never nice when LEDs explode.
