Accomplishments this week
1. De-scoped Electrical Demo
- Without the lab equipment (voltage source, multimeter, oscilloscope), I am unable to test if I am outputting the correct pulse signal to the stepper motor.
- Decide to use the Raspberry Pi to control two stepper motors and one servo to do the intended motor control sequence when the flip signal is triggered. The de-scoped project goal is to attach a code review to analyze when and by how much each motor is signaled to run, to demonstrate the control algorithm.
2. De-scoped CAD Simulation
- Without Techspark, I am unable to use laser cut nor 3D printers to fabricate new shafts and flippers. Even though I currently have a first version wooden shaft and turner but I didn’t fabricate dampers yet to prevent the shaft and flipper from wobbling. Hence that iteration does not reach the desired position accuracy. The de-scooped project goal is to use the CAD simulation on Solidworks to demonstrate intended flipping motion. I will also not fabricate a physical stand to hold a music book because of the lack of tools.
3. Electrical Component Shipment
- Order a plug-to-wall DC voltage source to power the stepper motor.
- Arrange with Quinn to have the electrical components shipped from the ECE lab to my home next week.
Progress for schedule:
- Changed schedule
Deliverables I hope to accomplish next week:
- Receive electrical components, ensure Raspberry Pi can work in my local network
- Get familiar with CAD simulation
