Star Wars Jawa Eyes for a Jawa Costume

Ok so my nephew wants to be a Jawa this year for Halloween.  Grandma is the seamstress, we got her an expensive Bernini sewing machine so she went crazy with the Jawa robe.  I took on the task of making the Jawa eyes.  I mean c'mon I've got all the materials to make them already, plus it involves LED's, and I have TONS of those that I bought off of eBay, just for this sort of project!

Unfortunately I never liked yellow or amber LED's so I didn't have any of those, they probably would have worked a little bit better.  But I do have tons of ultra-bright white LED's in various sizes.  So all I'd have to do is make some sort of yellow colored diffuser and I'd be set.

Plus I discovered a brand new composite material using tyvek and Gorilla Glue.  It's probably the best idea that I've had yet, and it can be used for a HUGE variety of projects.

With all the glue drying involved it's a several day project.  If you do make these please post pictures in the comments for this instructable!

I'm hoping to have pictures of the eyes at night with the whole costume after Halloween. 

There they are!

Step 1: Materials List

Picture of Materials List
1 Toilet Paper tube.
1 bottle of Gorilla Glue (or Sumo Glue), I used both
1 small tube of Silicone sealant
some bamboo skewers
bar clamps and spring clamps
1 or 2 Tyvek mailing envelope(s)
8 feet of two conductor wire
2 5mm bright white LED's
3 inches of aluminum foil from the roll
soldering iron
solder with flux
heat shrink tubing
paper towel
Yellow Mustard
4 or more razor blades, I used the double sided kind
1 black marker or matte black paint
1 piece of corrugated cardboard about 6 inches square
1 needle and black heavy duty thread
some newspaper for a work surface
some elastic banding from the fabric store

First of all, absolutely brilliant! Jawas are such charismatic little critters and it always seemed to me it would be fun to dress up as one, but the glowing eyes are so central to the whole thing I figured there was no use unless I could get them right. Now I have no excuse!

Now for my question: Where are the eyes positioned in relation to your nephew's head in the above pictures? You mentioned that they were meant to rest on the forehead, but I can't shake the idea that they're over his eyes here. Adjusted for the photo-op or am I just seeing things wrong?

Well thank you very much for the high praise! It's encouragement like this that keeps me making stuff! And I'm so glad so many people have checked out this instructable!

Now for your questions;

I had made the eyes so they could be positioned just over his eyes on his forehead so that he could see fine. I'm pretty sure he did reposition them for the photo, however. His grandmother made a thin black hood out of some kind of material that he could see through and breath through just fine.

I did try to figure out a way that I could make glowing eyes that he could see through, but in the end I just couldn't think of a way to accomplish that.
Thanks for the clarification! And by the way, I totally agree with your decision to have the eyes on his forehead: mask-making taught me long ago that one should not be too attached to having the creature's eyes in the same place as the human's eyes. I'm sure it looks fine anyways. And it's nice to know there's another challenge out there waiting for us if we decide to face it...

Cool, I'd love to see pictures of the full costume.

I just got a picture and posted it to the instructable right away.  The costume came out pretty good.

 "Leds have a very tight beam of light"
Hmmmm, what LEDs are those? because i think those propierties belong to lasers.
DrPeper (author)  santy224 years ago
Good Question!  Single chip LED's (like the ones I used here) typically have a viewing angle of 6 degrees to 60(ish) degrees.  Typically you are in the 20 to 30 degree range for most single chip 5mm component LEDs.  The ones that I used had a 20 degree viewing angle.

You get some spill out from the focusing lens but it's really quite minimal, 90% or so of the light produced by the LED is emitted from that 6 degree to 60 degree viewing angle.   So it is quite a tight viewing angle when compared with incandescent.  Incandescent bulbs spill out light in just about every direction (effectively 360 degrees), which is why they need a focusing reflector to get more of the light out of the enclosure.  CFL's are the same way but they simply wouldn't make any sense in this project, due to size and voltage requirements.  Now using multiple LED's with some kind of lens can increase the viewing angle, but I was trying to keep this as simple as possible.

Plus if you specifically look for a wide viewing angle LED's they are out there, but for most of my projects I like to stick with a low viewing angle LED.

Lasers' on the other hand would have effectively zero viewing angle because it's coherent light and that is the nature of coherent light.  Sure you get some spill out from the lens, but still effectively zero.  Now there are many different types of lasers out there, but the ones that most people have seen are laser pointers.  Which actually use something very similar to an LED (short for Light Emitting Diode) called a Laser Diode.

It's easier to convey this in a diagram, so I'll have to look one up and possibly add it to the instructable.

If you remember the original Jawas, it strikes me that they had 12V bulbs and maybe big battery-packs?

Well I didn't want my nephew carrying around a 12v battery so I wasn't entirely concerned about strict accuracy in implementation.  Rather I was just looking for accuracy in looks.  That and LED's don't produce the heat that an incandescent bulb does.  With an LED I can get away with 3 or 4.5 volts, which I thought would be safer.  Plus I've got a little LED fascination, they are way more efficient and the batteries last longer.  I pretty much try to make an excuse to use LED's in almost every project.

I was thinking only of the hard time they must have had to create the same effect - aren't LEDs wonderful?

You know I hadn't thought of it from that perspective.  It is certainly interesting to think about.

I got a chuckle out of the T-shirt I saw:   Jawas
