Introduction: Back to the Future Lamp & Clock

By

Originally, I started from the "high part", the "simple logo lamp". Then I thought: "Shouldn't I add a Back to the Future clock, in the style?" And that's it !

On the back, you'll see a small button, which changes the color, I put three different ones, but you can modify the code and add your favorite color.

Date and time are synchronized via Wi-Fi, don't forget to write your wifi credential in the code.

The components here : https://jeje-linge.fr/en/products/back-to-the-future-lamp-and-clock

Supplies

What you need:

  1. 2x red LEDs
  2. 3x displays
  3. 2x 220 Ohms resistors
  4. 1x 2.2K Ohms resistors
  5. 1m Led Strip RGB
  6. 1x Mini Esp32
  7. 1x Micro switch 6x6
  8. Wires

Step 1: Print the Parts

Print every part.

I used black PLA but you can totally make it with grey PLA.

White PLA for the letters.

Layer 0.2mm, infill 15% for everything but the letters.

Letters: layer 0.2mm, infill 100%

Step 2: Painting

I used metal spray paint.

Step 3:

Insert the "caches" in the letters B, A, O and R.

Then place the white plate inside the model.

Step 4: Solder the Leds

Solder two 220 omhs resistors on the red leds.

Step 5: Glue the Led

Glue the two leds in the model.

Step 6: Chain the Displays

Connect the 5V, GND and CLK of all the displays.

Use 1 wire per DIO input.

Step 7: Place the Displays

Place the displays in the spaces provided.

Step 8: Glue the Led Strip

Cut the led strip in 3 parts.

Glue every part.

Step 9: Chain Led Strip Parts

Solder every part together.

Make sure you put the DIN of the first part on the left side.

Step 10: Solder the Switch

Solder the switch and the "pulldown" resistor.

Step 11: Solder AM/PM Led

Connect the red led to the ESP32.

The two minus pin must be connected to the GND of the last display.

Step 12: Connect the 5V

Connect the two 5v (led strip and displays) to the ESP32 VCC.

Step 13: Solder the Led Strip

Connect the GND and DIN to the ESP32.

Step 14: Solder the Displays

Connect every DIO, the GND and CLK to the ESP32.

Step 15: Place the ESP32 and Switch

Place the ESP32 and the switch in their places.

Step 16: Stick the Labels

I printed the labels on self-adhesive paper.
