from Union Bridge Labs:
Part machine. Part monster. The yarn monster eats raw yarn and excretes perfectly rolled yarn balls. A wireless remote control allows for the adjustment of the speed at which the monster consumes your yarn. Yarn Monster eats other yarn winders for breakfast.
The yarn winder is powered by a stepper motor, which is driven by an Easy Driver & Arduino Pro Mini. The Arduino receives speed instructions via XBee from a remotely connected potentiometer.
The remote & controller boards were both designed in Eagle and etched using muriatic acid and H2O2. Click here to view an image gallery that shows the etching process.
