3D Printed Back to the Future TIme Circuit Clock

The front left LED .stl file was incorrect and has been updated. The time circuit clock will display the following via the LED displays.

Destination Time – (Top-Red)

The destination time is an area that shows a fixed date and time. Use this area to display an important date in your life such as wedding, Birthday or the date you first discovered this most excellent clock.

Present Time – (Middle-Green)

The present time is the current date and time. You set this initially when you download the Arduino and you can adjust the hour and minute via the RGB LCD display keypad.

Last Time Departed – (Bottom-Yellow)

The last time departed will alternate between three different important dates every 20 seconds. Use this for birthdays, the date you finished building the clock, the day you met your significant other, etc.

The time circuit clock will announce the time between the hours of 8:00 AM and 9:30 PM. The time is generated via the Music Maker MP3 shield. The audio files for the time announcement were recorded by my wife and are included. To enhance the clock further, I enlisted a voice impersonator that recorded the time announcements as "Doc Browns: voice. Contact information for the voice impersonator is included in this “Instructable”.

Power on message and time announce files are provided. You can change these by simply by recording new .mp3 files and putting them on the music maker board micro SD card.

The clock is 3D printed and utilizes (1) Arduino Uno, (1) Music Maker MP3 shield, (1) ChronoDot real time clock, (1) RGB LCD keypad, (9) 3 mm LEDs, (1) voltage isolator and a few other components. A complete parts list is provided at the end of this “Instructable”.

The .stl files for printing the clock parts, Arduino code, wiring diagram, decal template and the audio files are located here. The clock was printed on a Lulzbot mini which has a print bed size of 150 mm x 150 mm. Due to the smaller print bed, some parts require gluing.

The entire clock was printed with HIPS filament with the exception of the pushbutton extensions that were printed with black ABS filament.

The Clock is controlled by an Arduino microcontroller. The Arduino handles the interface to (9) four digit LED displays, (6) AM/PM LEDs, (1) MP3 Music Maker Shield, (1) RGB LCD pushbutton display and a Chronodot real time clock.
