Retirement Clock

The retirement clock is for retired people who only need to know the day of the week.

The retirement clock is a bit different from my other projects in that it requires a few components in addition to the 3d printed parts, and some knowledge of using arduino microcontrollers.  

The additional parts and items required are shown in the photos. 

I chose to pause the prints and change the filament color to make the letters show, but it could be printed all one color then paint in the letters.  

The assembly in snap together, except for a little glue necessary on the servo arm and stop retainer.   

The photos show the details of assembly and explain what needs to be done for the clock to operate properly.  

The arduino program is super simple and uploads with ease.  

The timing starts when the arduino is powered up, so to change the day correctly it needs to be powered up at midnight.   The arduino unit signals the servo to advance the day once every  24 hours.  

For the more adventurous, a rtc module could be incorporated with the arduino and the instructions modified to signal the day to change at exactly midnight, this would eliminate the necessary powering up at midnight.
