- 1 x Arduino Mega 2560 R3
- 5 x 1x8 5V Relay board
- 40 x single bubble unit
- 2 x conductive sheet for capacitive sensing
- 5 x 12V power supply
- 1 x 5V power supply
- 200 feets+ wire
The unit is designed with the ease of assemble and installation in mind. For example the legs have room for magnets for easily snapping on metal surface with adjustability; The Cloth-fitting ring allow quick replacement only for the needed parts.
- 3D printed housing
- Base unit (STL file here)
- Ring housing unit (STL file here)
- Cloth-fitting unit (STL file here)
- 12V, 0.45A computer fan
- 16 x WS2812 RGBW LED in ring PCB
- Sealed cloth bubble (Paper cut file here)
- All unit's fans Vcc are connected to relay's NO (Normal open)
- All relay signal pins are connected to Mega's digital pins (40 pins)
- All LED wires are merged in a row basis -> only 5 pins are required for controlling
Simplifed sketch for wiring and circuit design
- More animation patterns
- Real unit design, to control each unit with indivial MCU
- To test for 5V fan performance which can simplifed the circuit design
We are very thankful for the supports and leatures from Mr. Ken Yiu and Tim.
