Lord of the Rings Lamp

I needed this in my life... that's it !

All the components available on my website : https://jeje-linge.fr/pages/lord-of-the-rings-lamp

This is pretty simple to make and everybody will stuck on this lamp.

IMPORTANT : use WHITE or TRANSPARENT PLA only.

Supplies

What you need is :

• 1 Power supply 5v 2A
• 1 Arduino Nano
• 1 Connector DC2.5
• 1 Led Ring (4 parts)
• wires 20 cm

Step 1: Printing

You have to print 4 parts :

• The ring + cover
• The base + cover

IMPORTANT : use WHITE or TRANSPARENT PLA only.

I have designed several bases, choose your favorite.

Ring = > Layer : 0.1mm Infill: 0%

Base => Laker : 0.1mm Infill: 50% (minimum)

Step 2: Painting (black)

Assemble the ring and its cover then paint everything in black to make it opaque.

3 layers is generaly good enough.

Be careful: Don't make the letters opaque, paint from top and bottom of the ring, not directly the letters.

Step 3: Painting (gold)

Paint it in gold.

2 or 3 layers.

Step 4: Solder the Led Ring

Use little pieces of metal to solder the 4 parts the Led ring.

Step 5: Solder Wires

Solder wires on the 5v, GND and DN pins.

The wires should be 20 cm or more.

Step 6: Push Through the Hole

Put the Led into the ring cover and push the wires through the hole of the ring.

Then close the ring and its cover.

Step 7: Solder on the Nano Board

On the Arduino:

Solder wires on the 5v and GND pins.

Solder the data wire from the LED (DN) on the D4 pin.

Step 8: The Connector

Screw 5V and GND from Arduino et LED ring in the connector.

Be careful of the polarity:

(+) => 5V

(-) => GND

Step 9: Upload the Code

Upload the code in the Arduino.

Download the "Adafruit_NeoPixel" librarie.

Step 10: Close the Cover

Close the ring cover.

Step 11: Stare

ENJOY !
