Heart-Shaped LED Lamp with WLED and WEMOS D1 USB-C

A heart-shaped LED wall lamp to elevate your mood and bring cozy light to your space.

You will need:

🔌 Wemos D1 mini (USB-C)

💡 ~40 cm LED strip (max 10 mm width)

⚡ USB cable for power

🔧 Screws for wall mounting

Assembly & Setup

1. Install WLED firmware on the Wemos D1 mini and connect it to your home Wi-Fi.
2. In WLED configuration:
   • Enable Automatic Brightness Limiter
   • Set Maximum PSU current to 850 mA
   • Select your LED strip type
   • Enter the LED count under Length

   • Set Data GPIO = 2 (D4 pin on Wemos)

3. Wiring:
   • LED +5V → 5V on Wemos
   • LED GND → GND on Wemos

   • LED DIN → D4 on Wemos

4. Stick the LED strip around the inner wall of the base.

5. Insert the Wemos controller into the case and close the cover (press-fit).

6. Mount the base on the wall using the 7.5 mm mounting holes.

7. Connect via USB cable.

8. Snap the lamp cover onto the base (press-fit).

Printing Details

Optimized for PETG filament (not tested with PLA).

Recommended colors: dark filament for the base, white filament for the lamp cover.

The diffuser is optimized for light distribution: first 20 layers print without infill, ensuring softer light spread and hiding individual LEDs

 

The model is being further developed to eliminate a slight shadow in the middle caused by the slightly tall Wemos housing. Future revisions will improve this aspect.
