The hardware consists of 3 parts: the 3D printed parts, the electronics and the accessories.
- Adafruit Feather Board 32u4 BLE
- Adafruit Feather DC Motor + Stepper Wing
- Adafruit Neopixel Ring 24 LEDs
- Two Stepper Motors
- Screw Coupler
- DC Jack Adapter 2,1 mm
- Power Supplies on MicroUSB and Jack 2,1 mm
- M3 Screws
- Screws 2,5 mm Diameter
- 3d Printed Parts
The microcontroller and the motor driver are both feather boards from Adafruit. They are very suitable for this project due to theirsmall size. The LED ring is from Adafruit. The ring is equipped with 24 RGBWLEDs. Thus infinitely many colors and a natural white can be produced.
The motors are stepper motors, which are particularly suitable for soft and precise movements. In order to get the suitable 3D print file for other stepper motors with different dimensions, a parametric model is available on shapediver.com . Only individual dimensions of the motors have to be entered and the 3D model can then be downloaded as a stl file.
04 Test Run
There are 3 movement scenarios and a color selector for the LEDs.
In the next version, more lighting scenes, color changes, and different movements and movement speeds would be great.
05 Issues and Problems
The motors produce a very high and annoying sound as soon as they are screwed together. Like a kind of micro vibration. Does anyone have a solution to the problem?
