design of astronomical ball necklace

In this post, we'll be discussing the design of our openable astronomical ball projection necklace. This necklace features a hollow sphere that can be opened to reveal a small LED projector. The LED projector can be used to project images of the night sky onto the inside of the sphere. The sphere can then be closed and worn as a necklace.

The first step in designing this necklace was to create a CAD model of the sphere. We used a 3D printing service to create a prototype of the sphere. Once we had the prototype, we were able to test the fit and finish of the sphere. We made a few adjustments to the design of the sphere and then sent the final design to be 3D printed.

The next step was to design the LED projector. We wanted the projector to be small and lightweight so that it could be easily carried around. We also wanted the projector to be able to fit inside the sphere. We settled on a design that used a small LED and a set of lens that could be focused to create a small image.

The final step was to put everything together. We soldered the LED to the circuit board and then mounted the circuit board inside the sphere. We then placed the lens in front of the LED and focused the image. We were then able to close the sphere and wear it as a necklace.

Overall, we're happy with how the necklace turned out. It's a unique piece of jewelry that is sure to start a conversation.

The materials

The materials you will need for this project are:

-A clear plastic or glass ball

-A small LED light

-A AAA battery

-A small piece of black cardboard

-A hot glue gun

First, you will need to find a clear plastic or glass ball. The size of the ball will depend on how large you want your necklace to be. Once you have your ball, use a hot glue gun to attach the LED light to the inside of the ball. Then, use the hot glue gun to attach the AAA battery to the LED light.

Next, you will need to make a small hole in the black cardboard. This hole will be used to thread the necklace cord through. Once the hole is made, thread the cord through the hole and tie a knot to secure it.

Finally, use the hot glue gun to attach the black cardboard to the bottom of the ball. This will help to diffuse the light and create a cool effect.

When the ball is held up to the light, the liquid inside refracts the light and creates the illusion of a miniaturized starry night sky.

Can you look through a projection necklace?

We often get asked, can you look through a projection necklace? The answer is: it depends! If you have the right kind of projection necklace, then yes, you can look through it and see the stars in all their glory. However, if you have a lower quality projection necklace, then you might not be able to see anything at all.

So, what makes a good projection necklace? First, it needs to be made of high quality materials. The lens should be made of glass, not plastic, and the overall construction should be solid and well-made. Second, the projection necklace should have a good design. The best projection necklaces have a large lens that allows you to see a wide area of the sky. Third, the projection necklace should be properly calibrated. This means that the lens should be positioned in such a way that it projects the stars onto the inside of the sphere in a clear and crisp way.

If you have a good quality projection necklace, then you should be able to see the stars quite clearly. You might even be able to see some of the planets, depending on how good the quality of the necklace is. projection necklaces make for a great way to view the night sky, and they make a great gift for anyone who loves astronomy.
