SmartKnob is an open-source haptic input knob combining a brushless gimbal motor and magnetic encoder with closed-loop torque control to simulate software-defined detents and endstops. The project includes firmware, PCB designs, and 3D-printable hardware for building the device, including the SmartKnob View variant with an integrated round LCD.

Use cases

• build a haptic rotary input knob with adjustable detents
• DIY macro knob for controlling software with tactile feedback
• learn closed-loop motor control with a BLDC motor and magnetic encoder
• create a customizable volume or media control dial
• experiment with ESP32-based embedded hardware projects
• build an input device with software-configurable endstops

When to choose

• you want an open-source, hackable haptic knob you can build and modify yourself
• you need software-defined detents and endstops that can change dynamically
• you're an electronics hobbyist interested in motor control and custom hardware

When to avoid

• you want a polished consumer product ready out of the box
• you're not comfortable with soldering, firmware flashing, and PCB assembly
• you need a cheap off-the-shelf macro dial without a DIY build
