Light Up Leggings
Intro: Light Up Leggings
Create a light show with these light up LEDs. Wear them dancing and all eyes in the room will be on you. Wear them running and drivers will know to get out of the way!
This is super easy to do even if its your first time building a circuit.
I submitted these leggings to the Soft Circuit Contest! Check out all the awesome projects submitted and submit a project yourself!

STEP 1: Materials
1. Leggings
2. Conductive Thread
3. 2 Coin Cell Battery Holders
4. 2 Coin Cell Batteries (3V)
5. 2 220 ohm resistors
6. 12 LEDs
7. Metal Clasp or Snap (not in picture)
8. Needle
9. Cardboard - 5" wide and 9-12" long, cut the edges so they are rounded, this cardboard insert will be used to help you sew
STEP 2: The Circuit
Plan out your circuit on paper first.
Each leg is a separate circuit with 6 LEDs. The LEDs are wired in parallel. The rest of the circuit is in the back of the leggings.
This circuit can be transfered onto a t-shirt, bracelet, you name it!

STEP 3: Prepare LEDs and Resistors
I usually use LED beads but I had some small blue LEDs that I decided to use for this one.
Using a pair of pliers or tweezers curl the ends of the LEDs and resistors so they are easy to sew.

STEP 4: Prepare Leggings
Using a pen, mark where you want the LEDs to go while the leggings are on you.
Put the cardboard insert in the leggings where you are sewing so you have a surface to sew on. If you don't use this you will need to have one arm in the leggings as you are sewing and this will be hard.

STEP 5: Sewing the Circuit
Start with the LED closest to the foot of the leggings. Sew the positive end to the leggings. Sew up the leggings attaching only the positive ends of the LEDs.
Use the cardboard insert to help while sewing. When you run the needle in the leggings let it hit the cardboard and bring it back up through the leggings.
Continue sewing around to the back of the leggings. Connect the thread to the resistor. Sew the rest of the pieces in place as illustrated in the diagrams. Leave some thread slack when connecting one of the clasp ends so you can screw them together.
The other end of the clasp will be connect to the (-) end of the LEDs. Sew back around to the side of the leggings and end at the first LED you sewed on.

STEP 6: Light 'em Up
Put in the battery and twist the clasp together!
Its that easy : )

I also had a black tutu with fiber optic light strands in it for Halloween and it got torn or something. So I took the lights out (basically fishing lines) and I put them in a headband to hide the battery pack!! Turned out pretty cool!

if you're into that, although reading your comment I'm not particularly worried about offending you anyway

I normally get odd looks when I make that sort of comment xD

If you connect them in series, they all share the same current so will all be approximately the same brightness, however you'll have to add up the total forward-voltage, and subtract from the supply voltage (which must be greater) to determine the best value for the current-limiting resistor.
... then, if you wish, you can put several of THOSE CHAINS (each with their own resistor) in parallel if you wanted more LEDs.
EG:
+ LED LED LED LED LED LED RESISTOR -
+ LED LED LED LED LED LED RESISTOR -
+ LED LED LED LED LED LED RESISTOR -

+ LED resistor -
+ LED resistor -
+ LED resistor -
[etc etc]
Alternatively, find yourself something like a 9V battery, then you could do:
+ LED LED LED resistor -
+ LED LED LED resistor -
+ LED LED LED resistor -
[etc etc]
... with (let me see) (9V-2V-2V-2V)/0.1A = 300ohm resistors

Not to be overly critical but if I remember circuits correctly, one of the sketches shows the LEDs in series rather than parallel. Perhaps that was part of the design process.
