Christmas Decoration: Village in a Tree

In this project you will build a lamp in the shape of a Christmas tree. The inside of the tree is a winter Chirstmas village lighted up by RGB LEDs. The tree can turn in one side to show the inside village or to the other side with Santa Claus and his reindeer. You can check on my video for more details

3d printed part

Electronics components

• 1 servo motor 9g
• 5x LEDs RGB W2812B (can be more if you want more light)
• 1 Raspberry Pi Pico (or Pico W)

Tool

• sodering iron
• cutter pliers
• 2M screws 2x

You will need to print all the part in the stl file. Be careful when you clean up the village because it has small details

1. Glue the Santa piece to the village, make sure that you have their holes mate together
2. Press the servo horn (cut short) into the wing holder
3. Add the wing holder into the santa piece

You can place the Leds on the big tree part. Their position will be more or less under those holes of the houses. The number of Leds can be more if you prefer more light. Then pass the wire through the hole to the base

Add the servo motor to the base and pass the cable of the LEDs to the base

Mount the base into to big cone part and tighten it with 2M screws

Add the RP Pico into the base cap and connect it with the LEDs and servo motor wires then close the cap

Secure the LEDs with hot glue. This is to make sure that it won't stuck to the moving parts when it rotates

Add these two files on RP pico. I used Thorny to do it but you can use what ever you prefer.

Power the RP pico and test it. You can also modify the code to change the position and light settings

Enjoy your light or give it to the one you love.

Merry Christmas! (and happy making :) )
