So sclera contacts are ridiculously expensive and my Cable cosplay requires a color eye. A colored contact is doable but not ideal for a real noticeable trait. So I decided to make an eyepatch similar to the Solid Eye from Metal Gear Solid 4. It would be made from either EVA foam or wood but I'm having trouble with the light. What I'm going for is pretty much just the Solid Eye but with a flat, horizontal rectangle illuminated in the center. Preferably yellow.

Solid Eye

So I ask, does anyone have any tips or tricks they've used with LEDs or EL panels in their costumes? I've researched EL panels/tape/wire and LEDs best I could but I've never worked with them and I'm no electrician. Sometimes what I see seems simple and other times it looks way too complicated. Plus I don't know exactly what's required to power them and where to get it. So I'd appreciate anyone with any experience that could lend some advice or expertise. Also, does anyone know if EL panels are even bright enough to be seen at a lit convention? Thanks!

Hmm, I have some experience working stage lighting and prop lights but bear in mind that I'm not an expert. If you want to replicate that eyepatch, then a single LED would most likely be easiest and LEDs tend to be pretty bright. You'd need some copper insulated wire, the LED, battery, electrical tape, and solder. You can find these at electrical supply stores (Radio Shack might have it, depends on the store) and you can check hardware/home improvement stores too. The trickiest part will be voltage. You'll need to match the voltage output of the battery to the voltage needed for the LED of your choice. Not enough voltage and the LED doesn't light up or will be very dim. Too much voltage and you'll kill the LED. I'd recommend getting the parts and pieces and just experimenting with them. Here's a good website to check out for some intro to circuitry info (LEDs For Beginners

And don't be afraid to ask questions when you get your supplies. They might be able to better guide you on how to approach this project.

i would suggest a single LED diode you will need a resistor though depending on the wattage of the diode you get and the size of your battery to offset the power flow ( to much power will kill the diode and battery faster)

A tutorial i suggest is by a german cosplayer Kamui who does some amazing WoW cosplays and uses the diode method

If you have more questions then i suggest going to your local radioshack and if you explain to them what you are trying to do they should be able to help u out. Good Luck!

Go find a Led of choice. find out what voltage is,.
then using that knowledge go figure out what rate of resistor you need so you can limit the amoutn of power going to the led(and so it wont blow the led)
there are calculators for such things online. id reccoment using a button cell battery to power it.
