Introduction: Flux Capacitor Alarm Clock

Here it is ! The flux capacitor from back to the Future (more square).

It's an alarm clock and once the alarm goes off, it randomly plays sounds from the BTTF soundtrack.

I provide everything to make it.

How to use:

  • Setup/Stop button: Set the alarm time
  • hour + minute button: activate or deactivate the alarm ("0" alarm off, "1" alarm on)

When the alarm is rigging

  • hour or minute button: snooze 5 minutes (time can be modified in the code)
  • Setup/Stop button: stop the alarm

Special feature

  • hour + minute button then hold the hour button until the feature starts.

Enjoy !

Supplies

Print every part + plexi plate 100x100x2mm

Step 1: Electronic Components

Step 2: Painting

Paint the following parts:

Just slide the led inside the part.

You have to put the "IN" toward the outside.

Solder the 3 RGB together (see wiring diagram).


Step 4: Assemble the Coils and Diffusors

You'll see that I've put numbers on the coals, the "1" will be on the up left, the "2" right, the "3" down.

Glue the coals, the diffusors on the plate.


Step 5: Solder the Display

Solder four wires to the display.

Step 6: Solder MP3 Player

Solder the wires to the DFplayer and connect the speaker.

Solder the wires to the "Hour" "Minute" "Setup/Stop" buttons.

The wires (yellow and orange) have to be connected to the ESP32 first.

Step 20: VCC and GND

I used WAGO terminals to connect every 5v/VCC together and every GND together.
