I plan to build a dial that is able to control multi-factors such as brightness, colors, and wheel. I came up this idea with an old telephone dial and I wonder how one dial can control multiple tasks.
Technically, I was planning to build a programmable tactile dial. So it can transform the tactile effects and clicking points depends on what it will controls. For example, if there are 5 steps to control, then it will have 5 points that the user can feel each point. I will use a haptic motor with the motor drive.
I needed to set up capacitive parts and haptic motor on the dial, I need a slip ring to prevent twisting wires. So I used timing belt and
1 x rotary encoder (I tested a small rotary encoder but it already has tactile feels when it turns. So I used 600p/r rotary encoder just because it is smoother. I think it is important not to have any tactile feel from mechanical parts.)
And, if I have a rotary encoder with center hole, it would be much simpler for fabricating.
1 x slip ring
1 x MKR1000
1 x RGB led ring
1 x haptic motor
1 x haptic motor drive
1 x capacitive sensor
- DMX Ethernet
- Haptic motor
I tested a haptic motor with the driver code from Adafruit site. It works very well and simple.
- Quadrature rotary encoder
For my quadrature rotary encoder, I used Encoder.h library and connected to interrupt pins. Compared to the normal rotary encoder, it was very sensitive and fast.
