I'm planning on a Leonardo Watch cosplay in the near future, and I'm thinking of making light-up goggles to simulate his "Eyes of the Gods" power. The idea is to paint a design onto the goggles (or affix tracing paper to the front) that cannot be seen in normal light, then put a blue mini LED bulb into each goggle to switch on and reveal the design. However, I have no electrical experience, so ideas would be helpful.

The goggles look like this:[url]http://40.media.tumblr.com/3116380e599b36c7adf8aa67714d1fb0/tumblr_nmv0fhHISA1td08a3o1_1280.png[/url]

If you paint the design and put LEDs in, the "power" will probably come out darker than the surrounding plastic. From the reference pic, it looks like the cross hairs are supposed to lighter, but I'm not sure how picky you're going to be about that.

Your better bet for that is probably [URL="http://www.instructables.com/id/Edge-Lit-Displays/"]etching acrylic[/URL], as putting an LED on the side of that would give you pretty much exactly the effect you're going for. If you're not into the idea of dremeling (or don't have that tool around), I'm pretty sure there are places online where you can order laser-cut parts, so you could just draw it out and pay to have someone else cut the lens/do the etching for you.

Another thing to think about is the orange tint that'll already be on the goggles. Adding blue to it isn't going to wash out that color; you're gonna get some intermediate.

Also, in thinking about wiring, you'll definitely need some sort of power source-- maybe a small watch battery? You could hide the battery clip under your wig pretty easily (if you're using one).

Personally, my first thought was to buy and cut orange acrylic as the lens and attach tiny EL wire on it as the etchings.

But if that isn't possible then StarsCASSiOPEiA's idea is just as good.

Thanks for the help. I don't have a dremel, so I might use a knife. Do you think the orange color of the goggles will be a problem? I can use two kinds if needed, one regular orange, and one etched clear. Also, the designs I see on the example are flat plastic. Would curved plastic give off a different effect?

#5 StarsOfCassiopeia on 3 years ago

It might be possible to do with a knife, but I wouldn't count on being able to get clean curves or detailing, especially since you're working on a curved piece. The edge of a sander might work? You could also try etching while it's flat, and then use heat bending to shape your piece after the etching is done.

The "problem" with the orange will most likely be that you won't be able to overpower the orange with blue LEDs in a way that makes it look all blue. That's your call on how you wanna do it, but two separate lenses would definitely solve that problem.

The curve shouldn't make a difference! It's just much easier to work on smooth, flat surfaces, so that's what most of the examples are.

Ex, [URL="http://www.dimmableledpanellight.com/photo/pl1916508-odm_oem_ultra_slim_led_light_guide_plate_customized_acrylic_laser_engraving_sheet_for_building.jpg"]take the wine bottle in the back of this pic[/URL]-- it's obviously curved, and the tree is etched!

orange lens + blue light= green effect. That's physics, no two ways about it unless you get into complicated stuff.

I've actually etched glass before, using chemicals and some kind of stick on tape, but I'm unsure if hydrofloric acid would work on plastic. Also, I don't think I have the materials and know-how to heat bond. If I etch this way, how do I do it safely?
