Stepper motors produce accurate, computer-controlled motion for applications such as robotic arms and paper-feed mechanisms for printers. They require current pulses delivered through a special ...

[Neumi] over on Hackaday.IO wanted a simple-to-use way to drive stepper motors, which could be quickly deployed in a wide variety of applications yet to be determined. The solution is named Ethersweep ...

The world is digital today, and most information is represented in numbers. However, human nature is more “analog” and better represented in the old-fashioned way, using pointer gauges and bar graphs.
