Day Clock

For those long quarantine weeks where the days blend together. This clock uses a servo so the clock hand always points at the center of the day, it does not "sweep" through the day smoothly like a normal clock would; at midnight, the hand moves to the next day. Thanks to the gearing, this works with a normal 180 degree servo. Code is included, just update to your WiFi information!

Notes:

Print the clock hand at 100% infill, everything else can be at 20%. I used a brim for the clock face to prevent warping and changed the filament between layer 15/16. Edit: Added separate files for the clock face, rings, and letters so it can be printed on an SLA printer and glued together.

Post-Printing

• Trim brim from clock face, including from notch at bottom 
• Push the servo into the slot until it hits the bottom 
• Screw servo gear onto servo horn 
• Attach servo horn to servo 
• Place box on top of servo and coil cable inside, connect to Wemos D1 
• Put clock hand through clock face into clock gear, align to Saturday 
• Place clock in base; I used a dab of glue to prevent it from moving at all 
• Run Day_Verification to calibrate middle of day values 
• Update values in Clock.ino and upload
