My main goal of this project is to make disco light that cast a good shadow.
I purchased an acrylic cube as a base, an acrylic cylinder to put light color filter around the light, and all other electrical parts.
- Acrylic Cube: $26.99
- Acrylic Dome: $16.98
- Acrylic Cylinder: $11.99
- 12 Volt Battery: $3.42
- Battery case: $5.99
- Motor: $15.98
- Extension Cord: $7.99
- LED light bulb: $9.69
- Cellophane wraps: $9.99
- Total: $109.02
As you can see in the picture, I used the lantern cord to hold the cylinder as an axis and put the motor on the side of the cylinder. Laser cutting the precise distance between cylinder and motor was a little tricky, but I managed to get the right distance by several trials of cutting.
For the upper part, I put aluminum foil around the acrylic dome with some holes to project light on the ceiling.
I am not happy about my final project because there were many things I didn’t make concern about issues, such as gear ratio and light. The light was not strong enough to have a good shadow, and the motor wasn’t fast enough because I didn’t consider gear ratio. I should’ve made something within my scope. 🙁
