Homemade machine puts a new spin on winding yarn
If you’ve ever wanted to wind balls of yarn, then look no further than this automated machine from Mr Innovative. The YouTuber’s DIY device is powered by an Arduino Nano and an A4988 stepper driver, spinning up a round conglomeration of yarn via a NEMA17 motor and a timing belt.
The ball is wound on an offset spindle, which is mechanically controlled to pitch back and forth and spin itself as the overall assembly rotates, producing an interesting geometric pattern.
User interface consists of a potentiometer and 16×2 I2C LCD display, allowing Mr Innovative to set the winding speed as a percentage. As seen in the video below, it’s able to “spool up” at an impressive rate, potentially creating lots and lots of balls o’ yarn as needed!
