Zaku: Monoeye lens

Time is running out. I needed to make a decision on the mono-eye fabrication. Many options had gone through but none would look good or had too many safety compromises.

This one is the least that looked the best. Still kind of dangerous though. O well, I'll have to keep an eye on her then. (uh.. sorry)

Lexan plastic. Heating it up in my toaster oven. When it starts to droop in the window, I pull it out right away.


The best form I had around the house was this paint can. Whatever works!


Perfect diameter

To shape it further, I just took it to my belt sander. 


For the tint, I used some leftover auto tint.




Made a small accent ring out of craft foam. Hotglued it on. And voila!


Now, all i have left to do is:
- screens in the side windows
- hot glue the lens in
- custom cut some foam to fit my daughter's head
- maybe another final coat of top coat to seal things off a bit more for durability

Eye Lens Redux

Eye Lens:

Here we go again! My second (and hopefully FINAL) attempt at making the eye lens for the build. 

To recap my requirements on this sub-project:
- Must not limit my vision, much
- Should have detail
- Tinted yellow
- Must be lit up.
- Lights must not be seen from the outside
- Lights must not be glaring back at MY eyes.

Had put a lot of thought back into this one. Going to start off with a piece of clear lexan plastic. I think this is good approach.
Since I already have the shape of the eye lens from the previous build attempt. I'm going to use it as a template for the curvature. Here I'm laying it down on a piece of 2x4 wood. I needed a shape to put the melting plastic onto. And the wood can handle the heat.

Cutting the shape out with a jigsaw.


I stole this toaster oven from my wife years ago. Started out when I was secretly baking my sculptures in it before. Got caught by the wife.. and said something, something.. and she just gave me the oven! Woohoo!! Score! Anyways, inside the oven is a couple strips of lexan plastic. Warming it up for 5-10 minutes. The moment I can see them droop, I pull them out and put it on my wooden form....

Almost lost this piece. You can see some bubbling at the corners! Luckily, the bubbles are outside and would be cut off.


Cutting them out with my dremel.

Quick test fit. PERFECT!

Now, for the details. I'm thinking of frosting them in. To achieve that, I just mask out a simple design. With my dremel again, I used a steel brush attachment, and just went over the exposed areas.

I could use some fancy window etching solution to frost the details. But, that would mean money. And I rather not spend money if I didn't have to. The return wasn't worth it. Simple economics. hehe

TEST: Can I see out of the new lens? 
Yes! Yes, I can. Even in the frosted areas, I can see vague shapes. So, this is successful.


TEST: Does the detail light up? 
Yes, perfectly!! Success, again!

TEST: Are the lights visible from the outside? 
Nope. Since the lights would be mounted just out of sight. It's perfect again. Another Score!

TEST: Would the lights be glaring back into my eyes/face?
Nope, eventually, I will be mounting the LEDs with hot glue. Then I'll be painting the globs with dark matte paint. The light would only be directed at the lens itself.

PERFECT SCORE!!
