3D printed desk clock with silent stepper motor drive
This is a 3D printed clock using an Arduino Nano and a custom motor control circuit to drive a stepper motor. The motor control circuit allows 64 position micro-stepping to drive the sweep second hand with a smooth and nearly silent action.
The STL files are available at MyMiniFactory at myminifactory.com/object/3d-print-183452
The custom motor controller is available on Etsy at etsy.com/listing/1063320628
06-Jan-23 Update: I made a new quieter motor controller and uploaded new files to MyMiniFactory. If you purchased the old design, you have access to the updated files. This new controller uses easy to find parts and adds a precision real time clock with an accuracy of around a minute per year. Details are at youtube.com/watch?v=PR4PXR7RXEY and on my web site at stevesclocks.com/sp6
