My first step was to connect the two CD together to form a wheel. My plan was glue the tape roll between two CD then use the clay to fill inside the tape roll area, lastly run a hollow tube through the hole of the two CDS. But the hole of the CDs are not big enough, so I decided to use the drill to make the hole larger. It works!
I made a 30cm*20cm base, two 11.5cm*3cm stands, and two bevel edge stands. I used hot glue to connect them, it works really well.
I decided to use a straw (it’s very fit in the hole) to go through the “CD wheel” which can hold the “CD wheel” on the holder.
On the top of the two stands, I made two hollow tubes. Therefore, the straw can go through it.
I made a handle on the left side, it is for left-handed people. Because the handle is made of wire, I added some red tape on the handle to increase the safety factor.
I used a rubber band to connect the CD wheel and the DC motor. Additionally, I put a gear on the DC motor, it can fix the rubber band and boost the speed of DC motor.
I used a CD to be the major important material of the light. The first time I chose to use separate wires and LED lights to connect with the DC motor, but the contact is not good, the light is not easy to light. So the second time, I choose to use LED light that already connected with the wire, that’s works much better.
This piece of paper has been hollowed-out by me, and while the lights have been running through “Joyful”, “Joyful” can also be printed on the wall so that the generator has become the projector. And the small thing can help to put the paper.
After I had done everything, I decided to paint my design so that it would be more beautiful and attractive which can make my audience more enjoyable.
Gather feedback from others:
The generator doesn’t work sometimes. (the light is not lighting)
In my statement above, I said that I added gears to make DCmotor rotate faster. I also used LED light wire instead of the separate one.
