Electrical beads spinner (with motor)

thingiverse

I have seen this thing: https://www.thingiverse.com/thing:1003559 I came directly the idea, which perhaps equipped with a motor. And here is the result. I have decided to make a very simple circuit so that everyone can produce it. A power supply, switch, motor and a potentiometer. The spinner can not only be switched on and off, it also can set the speed. The speed control is not very precise, but it is very simple. The housing I printed upside down (top side on print bed) with supports. All other parts I printed without supports. The ground cover I had fixed with 2 screws. After that I added 3 clips which should hold the cover. If that works you dont need the screws. Motor I used a motor from some electronics-trash. Its a Motor from type "RF-310 6Volts" with motor diameter of 24,4mm and needs a long axis! Switch Snap-In switch with dimensions of 19,2x12,9mm Potentiometer 330 ohms and axis diameter of 6mm. If you dont find the value of 330 ohms you can use one with 470 ohms and connect a parallel resistor with 1k to it (see schematic). I have used a linear potentiometer. You also can try a logarithmic one, could make the regulation of the motor more evenly. Power supply Any power supply with 5 to 6 volts and at least 300-500mA (I used an old one with 5,7V/800mA). I hope I have nothing forgotton ... if I did please write a comment ;-) Thats all for now, have fun!
