Design sprint for Polyfyge 2.0
Week 33 Participants:
- Jerry de Vos
- Jose Carlos Urra
Design Principles
We are aiming for a mini centrifuge
Architecture design principles:
Avoid having as much floating components as possible. Solution:
- Mount as much components as possible in the PCB:
- Microcontroller board, Power Sitch, Power connection, Screen and Digital encoder
- Mount as much components as possible in the PCB:
Make the architecture design and placement of the components manufacturing agonostic(as much as possible).
- This means that people should be able to fabricate the casing with a 3D printer, laser cutter, vacuum forming etc.
Design requirements
- Add a mechanical switch for the led to ensure safety
- Part of the rotor should be visible (transparent).
- Use a teensy or similar solution that holds an SD card to store data about product usage, like cycles, etc.
- The PCB should be accessible via easy disassembly steps, ideally one step.
- Electronic connections should be robust and standard:
- PCB must facilitate ease of soldering.
- The electronics should be easily testable without having to assemble the whole product.
- Make the motor mount robust
Tasks and tests:
- Make a preliminary PCB CAD module focused on architecture and component placement.
- Rationale: We want to print the PCB prototype, or laser cut it to se how it fits the requirements above.
- Make CAD design focused on fast printability.
- Print it and test it with new PCB CAD prototype.
