Watch Winder

An elegant watch winder with wood slots (3d printable panels now available!). I made a new version, smaller than the previous one and with the possibility to install Pogo pins for a second winder. 

It works with a D1 mini microcontroller and a stepper motor.

- New watch holder and rotor to fit with my new Watch Box

Component list:

• Pogo pins: https://s.click.aliexpress.com/e/_c2xJoAxh
  You need a 4P pair (motor cables) and a 2P pair (motor driver power supply). 
• D1 mini microcontroller: https://s.click.aliexpress.com/e/_c2yz2bsB
• Stepper motor with motor driver: https://s.click.aliexpress.com/e/_c3bp08OR
  You need a motor + driver for each winder you'll made.
• 6001ZZ bearings: https://s.click.aliexpress.com/e/_c3FSeHun
   

Please, take into consideration that my connections used between D1 mini and motor driver maybe don't work in the same order for you (may vary depending on the motor used). So if the motor doesn't rotate properly, change the order unless you find the right combination.
 

Connections for single winder

Connection for double winder:

Firmware for single and double Winder available on my Drive

The D1 Mini will generate a WiFi network named “Watch Winder” for the first 10 minutes after power on. During this time you can connect to this net and configure your winder. The WiFi network SSID and password  (default 12345678) can be edited in the firmware. Also the 10 minutes of WiFi visibility can be extended.
To configure your winder, navigate to this url http://192.168.4.1/ (the default IP may vary, check Serial prints) and setup the number of turns, speed and delay. 
Speed 1-5: 1 is the highest speed, 5 the slowest.
Number of turns: for example 2 turns mean that the winder will do 2 turns clockwise and 2 turns counterclockwise then delay for the delay time.
From my tests, the best configuration is 3 turns - speed 2 - delay 7.
