Here's a couple shots of the head with all the projector details and the main eye surround finally in place.
Because I didn't want to do any cutting at all on this metal head, I cheated a little and cut about the last 1/4" off these side details and mounted them directly to the dome with resin. Then I drilled holes for the LEDs, I put six in each one. They aren't straight (drilling into metal is not my strong suit), but you won't see them when I finish the insert I am making for these. These blinking blue / red LEDs were something I had left over from another project, so I figured I would use them.
I then bought a couple of those capsules from the coin operated toy dispensers you see at the front of the grocery store. I used three small ones for each projector. They fit perfectly, didn't even need to cut them.
For the other large eye on the bottom, I wasn't sure what to do. So I took the largest toy capsule and cut about 3/4" off the bottom. Then I bought this really cheap tire gauge from the dollar store:
I pulled off the plastic front piece, turned it upside down, mounted the remaining 1/4" of the toy capsule on to it, and sanded the whole thing to make it look a bit frosted. I then took a small top portion of one of the capsules, filled it with hot glue, and mounted it inside this eye. That will help diffuse the light a little. I then mounted the eye over the LED.
Here's how it looks lit up. I have a solid white LED in the front projector, 5 solid blue LEDs in the main eye, one blinking red / blue in the lower eye, and 12 blinking red / blue in the left side pieces.
I have an idea for the 12 red / blue LEDs and just need to finish the main eye and I think it's done!
