Christopher Hawkins made this cool DIY 3d printed stepper motor: This is a programmable stepper motor and driver that I made out of some nails, magnet wire, neodymium magnets, a digispark microcontroller, and a 3D printed piece that I designed … Read more
Trandi blogged about his Stepper motor bluetooth serial driver project: How to put together a simple bluetooth driver for a nice little stepper motor (Mitsumi M35SP-11HPK) that I salvaged from an old Canon printer. It uses a small Attiny85 (the … Read more
YetAnotherStepperDriver is a breakout board for the DRV8825 stepper motor controller IC. The IC can put out 3A of current, so proper cooling is a must. This is the reason behind so many vias around the bottom pad of the … Read more
This video by Ricardo Caratti demonstrates his method for controlling a Magnetic Loop antenna with an Arduino. The antenna’s tuning capacitor is adjusted using a stepper motor interfaced with the Arduino equipped to read IR commands sent from a compatible … Read more
Dino played around with some stepper motors by using them to generate electricity. The output is AC so he used a full-bridge rectifier, sometimes refereed to as the Graetz rectifier, to get a single direction signal, basically the absolute value … Read more
