Developer Hugo Lispector, who created El Trackpad, today released Controlly - a new app that uses PlayStation and Xbox controllers as remotes for Mac.Ĭontrolly has some key differences from El Trackpad besides one app working with wireless controls and the other running on iOS devices.

However, the app requires the device to be connected to the Mac via USB, which is not ideal for some situations. For the right application, a closed-loop stepper motor may be the best choice.Last year, I reviewed El Trackpad, which is an app that lets you control the mouse cursor on your Mac from an iPhone or iPad. They also have lower overall cost, despite the addition of feedback and the need for tuning. Although their performance is still somewhat below that of servo motors, they offer different advantages such as holding torque. By introducing position and velocity feedback, closed-loop operation helps prevent the homing issues associated with stalling.Ĭlosed-loop stepper motors provide higher position and velocity accuracy than open-loop stepper motors. Stepper motors also can be operated closed-loop by adding an encoder or resolver. For open-loop stepper motors, the drive does not need to be tuned, which simplifies commissioning. Eliminating feedback devices cuts both cost and complexity. Stepper motors are typically operated open loop (without feedback). This ensures that positional errors are not cumulative. The motor can be very accurately commanded to move to a specified angular position, however. Frictional forces prevent stepper motors from being reliably positioned to within a single step. The greater the number of steps per revolution, the greater the resolution-but only to a point. Stepper motors can be driven in various modes such as (in order of increasing steps per revolution) full-step mode, half-stepping mode, or micro-stepping mode. The amount it turns is a function of both drive and windings.

The drive delivers a series of pulses to energize the windings, causing the rotor to turn. Stepper motors are 50- to 200-pole motors that can deliver high-resolution positioning for a variety of low-end applications.
