Geared Clock Remix
thingiverse
I modified the Arduino code from this thing:http://www.thingiverse.com/thing:570797 It was modified to use the 28BYJ-48 stepper motor and ULN2003 drive module. The picture shows an Arduino Pro Mini and a bread board with the drive module installed, but any Arduino will work - UNO, Nano, Mega, or Pro Mini is fine. There's also a switch which sets the clock with each press counting one minute forward. I made the standoff's using this thing:http://www.thingiverse.com/thing:351092 I had to adjust the X and Y dimensions by .2mm each to fit the gears loosely in place. Put the minute and hour gears on, setting them at 12 o'clock position with them facing each other directly. Printer Settings: Printer: CTC Rafts: Yes Supports: No Resolution: .2mm Infill: 40%
