radar eye

So I made a lens, and painted and mounted it and my radar eye.

The lens was made with a plastic ball from Micheal’s crafts, which I painted the back of with black primer. This was the item used:

It’s a 2 piece plastic ball, I think meant for christmas decorations. Its only like $2 and thick enough that it should hold up. I got the 100mm one, since I thought the curve looked best behind the eye. To trim it down to the right size I placed the hemisphere in the eye opening, and traced around the rim with a marker, then cut out the lens from the hemisphere with my dremel, then sanded it until it would sit flat against the dome.

I mounted the eye to the dome using the method in the wiki here, it is held on my 4 4-40 screw shaft superglued into small holes in the eye and bolted inside the dome. Seems secure enough.

I think the dome is looking grea tso far, and I hope to recieve several more servos and a pololu serial servo controller in the next day or 2 to continue making my various panels open 🙂
