How to make your Christmas tree look so different?
Today, we’ll follow Mr. Hartvik’s instruction and make a special LED lighting with 3D printed parts and Teensy 3.2 development board.
With this special designed LED lighting, you only need to touch the sensor wiring under the Christmas tree to change the lighting patterns in 18 different bright looking.
I – Materials & Tools
3D printed parts: https://www.thingiverse.com/thing:4691935
Teensy 3.2 develop board
USB cable (longer than the tree height)
WS2812 RGB LED lamp (cuts to 62 led /length 105CM)
10 Ω resistor
1m three color wiring (0.5mm / 22 AWG)
PLA filament (transparent & black)
Anet ET4/ET5 3D printer
Hot glue gun
II – Make the Christmas Tree Lighting
Step 1, print the parts
Step 2, assemble parts together.
* insert the LED strip wiring into the printed tree trunk (star holder).
* don’t glue anything together here.
III – Soldering & Programming
Din <—> Pin 2
+5V <—> Vin
GND <—> GND
That’s all the instructions from Mr. Hartvik to make a 3D printed LED lighting with Teensy 3.2 develop board for decorating Christmas tree. Sorry that we’re for now unable to find the programming procedures here. If you’re capable of doing Arduino programming, have a try on this project and put a beautiful lighting on your Christmas tree with 3D printed parts.
