1/29/17
- created first draft of the project proposal.
- explored alternate project possibilities, including displaying just on a cylindrical surface, removing inner led display volume, and making the display scalable.
- considered which components to use, settled on the stepper motor.
- considered using individual LEDs or strip LEDs, and settled on individual LEDs to ensure LED can be individually controlled and visible from multiple angles.
2/7/17
- switched LED to addressable LED strip due to limited number of ports on the arduino
- tentatively decided on about 10 layers of LED
- designed pole, arudino and battery layer, and first LED layer
- 3d printed designed layers
- modified project proposal
- redesigned pole to be hollow so wires can be held inside the pole
- redesigned layers with tolerance on connecting parts
2/14/17
- ran test on the strip LED with Arduino mega, confirmed that each light can be controlled individually
- determined that motor controller and separate arduino was required for motor, and added components to the budget
- arduino battery layer failed to take into account the size of the ports on the arduino mega; fixed design and reprinted
- 2nd LED layers printed
2/21/17
- finalized budget: switch from AA to D batteries, switched to buying 3 led strips, removed wires and electrical tape from budget
- tested motor
