Lazy Susan on Ball Bearing (USB Powered)

thingiverse

This is a "Lazy Susan" for a curing station (or whatever you would like to use it for). I designed it to run with a cheap (28BYJ-48 ULN2003 5V) motor/controller combination, ball bearing and a rubber band. Here is what you will need (other than the files printed): Motor + motor controller: 28BYJ-48 ULN2003 5V 30mm ball bearing Arduino Nano/Uno/Pro Mini B10K potentiometer Wires Rubber band Assembly: Put ball bearing on base. If the bearing is too loose you can use one or to layers of electrical/insulation/scotch tape to make the base knob a little thicker. Screw the base in place where and place the top on top of the ball bearing. If the top is loose, use tape to thicken the outer part of the ball bearing. Mount the motor onto the holder and screw the holder in place and slide the spool onto the motor. The distance of the motor to your Lazy Susan depends on the length of your rubber band.The band should sit tight. Put on rubber band. It should slide into the groves of the top and the spool. Wiring: Arduino -> Motor Controller D8->In1 D9->In2 D10->In3 D11->In4 5V-> + Gnd-> - Arduino->B10K Potentiometer (Knob pointing in your direction) 5v->Left Pin A2->Mid Pin Gnd->Right Pin I can post code that works without the speed control (potentiometer) if anyone is interested. EDIT: I also added a version for a smaller bearing (22mm)
