Light source preparing:

How to make a projector with a light bulb ? When the artificial stars are ready, the task is to prepare the light source. That means you have to use a light source from which all the LED light will attach. Torch lights or any other large over-illuminated light source will work well.

However, another alternative way is to make your light source. For this, take a one-meter LED strip and 0.14cm PVC pipe and make sure that these can perfectly fit inside the box. 

Firstly, wrap up the LED strip with a 0.14 cm pipe. After that, connect all of the wires with the battery power connection. At the last step, connect the circuit with the LED lights.

How to Fit the Star Projector Together

In the case of a soda can, firstly, cut the bottom of the can in a round shape. Use the sharp cutting blade to cut the round bottom, as we mentioned above.

Since using a box is easier for the star project, we discuss the project with a cardboard box. Here are the steps.

Step 1:

Cut the box bottom with sharp scissors. Use effective glue to attach the five pieces of square shape surface. 

Step 2:

After attaching all parts, keep one side of the box open and then use tape to cover all corners so that unexpected light can’t enter the box.

Step 3:

In this step, make a hole on the sixth square to attach the star project with the light source. In the meantime, remember that you can cut out under the soda can.

Step 4:

This time connect the light source to the specific hole, a box or a soda can. Use a good amount of glue around the light source to keep it straight.

Step 5:

If you use a torchlight, then be careful to connect correctly. And keep a system so that you can take off the old battery anytime.

Besides, you can use an LED strip for the main light source. In this case, it is good to set up the battery outside the box that is helpful for easier access.

Step 6:

Now, close the bottom part of the box or soda can because you have already completed the star project task. After that, apply glue around the bottom of the box and ensure that light can’t come from outside. 

Final step:

Place your star projector box at a specific station. When it gets dark at night, turn on your projector and enjoy a pleasant night sky with bright stars.
