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/pages/bttf-lamp-and-clock

Supplies

What you need:

  • 2x red LEDs
  • 3x displays
  • 2x 220 Ohms resistors
  • 1x 2.2K Ohms resistors
  • 1m Led Strip RGB
  • 1x Mini Esp32
  • 1x Micro switch 6x6
  • 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.

Follow the procedure above

Step 19: Great Scott!

I finally invent something that works!
