LED lighting Tutorial

Hi All,

I created an LED lighting tutorial earlier this year, link here: http://www.youtube.com/playlist?list...4wivgwj0UQKeb9

It's 5 videos long and it goes into the Physics of using LEDs for a simple light-up project.

I kind of made up a design as I went along. After having finished:
my Starry costume,
my LED Party Dress,
my Drippy Plushie with light-up Lantern and
my Panty Angel Wings,

I was inspired to create this tutorial and share my knowledge through these projects. Just as a disclaimer, I'm not a Physics major...it's not perfect, the sound is kinda variable, but I hope you can get something out if it. ^^;;;

I'm constantly working on incorporating lights to my cosplays and you can check out my progress as I go along on my Facebook page: http://www.facebook.com/cherryteagirl

Enjoy and hope to see your shiny cosplays!

Awesome tutorial! I had never thought about using desoldering braid as a conductor on fabric!

I think you may have gotten the math a little off, though. You can include the voltage drop of the LED when calculating the resistor value. So, if your LED has a 2V drop and 15mA draw, if you're feeding it with 3V, the resistor would be (3V - 2V)/0.015A = 66.67 ohms.

It's not a big deal necessarily, but if you don't factor in that voltage drop then your resistor will be more ohms than it needs to be, which means the LED will be significantly dimmer.
