kinetic sculpture
Inspired by the spinning wheel, I want to create a similar one. This is how the end product looked like.Due to the thickness and heavy weight from the parts, the motor wasn't able to hold all the parts together. So I can only move the part with motor, without the LED lights on. Then with the LED lights on part, I need to make it move manually.
Final product with motor on.

Process
I first created a wheel that has holes in it so it can also use arduino lights to make it shine.
Wheel model in Fusion 360
I used strandtest wheel script to make the Neopixel light up
Then I laser cutted the parts in 1/4 wood. I didn't choose 1/8 becasue i was worried if it may break.
I assembled them together.
When I tried to make all parts spin, I realized the motor holder was too small to hold all parts together.
Then I decided to make it stick. Instead of using the wood one, which I need to drill a hole. I decided to design it myself and 3D print the stick.

3D printing the file took a long time. 4 hours but I was able to learn how the machine works.
However, the wires I attached to my motor broke even after applying hot glue gun on it.

I also tried to drill a hole to the stick and make the motor acctach to it.

Other modeling
I am interested in learning how the joints work and create wheels.
I learned to use add-ons scripts (spurgears) to make the gears
Following the tutorial, i was able to make the wheel spin.

Measure voltage. Ohm's Law.
I am powering using 3.3V. The total voltage is about 3.3V. The resistance is a 300 Ohm resistor. I = V / R = 3.3V / 300 ohm = 0.011A = 11mA
