Repurpose high RPM server Hard Disk Drives into functional lab equipment
Ingredients to make one:
- Plastic enclosure: repurpose a similar sized mass produced container like a lunch-box
- 3D Printed Bowden Tube holder STL merged with a coupler you can customize to fit the drive you have on hand using the OpenSCAD file
- Electronic Speed Controller (ESC) module: repurposed from a broken drone, commonly available module for drone motors
- Arduino nano or similar microcontroller with a potentiometer to control RPM
- Optional: LCD display to show estimated RPM
- Optional: Infrared sensor to count and display accurate RPM
- USB power supply for the microcontroller, DC power supply for the servo. Be sure to use a common (-) negative if using two power sources.
- Follow wiring diagram from the source:
