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!

You need:

• A Wemos D1 Mini
• A full size servo

The Wemos connects to your WiFi and automatically sets the correct day, there's nothing to set or keep track of!

Supports:

No

Resolution:

.2

Infill:

20%

Filament: Hatchbox PLA Variety

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
