Thread: Template or Mechanism Ideas for Servo Driven Eyes

Tweet

I'm going to be making some servo controlled eyes for my Madame Leota Tombstone but my brain is fried and I'm having trouble wrapping my head around how I'm going to attach the eyes to a plate and then to the tombstone. Just as Madame Leota, the eyes are going to open and then look left and right and then the eyelids will close.

If anyone has any suggestions, I would appreciate it.

Thanks.

Hi, how is your project coming? I am working on a drawing for you, but I have some questions. What are you using for eyes? What about the eye lids? Also, how much room do you have?
Thanks

I've been using a video I found on Youtube http://www.youtube.com/watch?v=QnZ6Q...feature=colike to help me. I am using half of a 2 inch plastic ball for the eyelids and ping pong balls for the eyes. I put it on the back burner because there is not enough time this year to finish it. I will be getting back to work on it after Halloween though.

OK, well post a picture of what you have so far, when you're ready to work on it again. How far allong are you?

I had to redo the design because I ran the metal through the inside of the wood and found it was a pain in the butt if I wanted to make adjustments (that and the plywood was driving me nuts). I found MDF was available and might work better. I made some forms for the eyeballs but I think I used MDF that might be too thick so I'm going to use a thinner MDF that I just found I had. I need to find something that will hold the metal without bending it (I might use metal tape). I'll try to take a picture of what I have so far tomorrow.

How much force in being applied to the metal? You could hold it in place with contact cement, or JB Weld. Did you figure out how you're mounting the eyes? I was thinking you could drill a hole in the bottom, fill them with resin, then re drill the hole to about 1/2 an inch deep. Then set the eyeballs on studs that are attatched to your plate. Use a little grease to prevent them from binding. On the back of the eyeballs have a stud sticking out of each one with a ball joint on the end. This would be where your linkage would attatch to make them move.

Here are some pics in a photo album http://www.halloweenforum.com/member...onic-eyes.html. There isn't much force being exerted, but it does have to move. This was the first design so the 2nd isn't going to be the same as first, but very similar.

OK, I get it now, the metal is the shaft that the eye lid pivots on. So the eye lids look like what I was thinking of, only I would have done lower eye lids as well. How are you going to mount the eye balls? You may already be aware of this company, but if not check out this site for some different hardware that may help. http://hobby.dubro.com/

I figured out how to get the mechanics of Madame Leota working. I created another thread showing my progress. Madame Leota Tombstone Build Using Servos

Thank you everyone.
