No Prints Yet
Be the first to upload a Print for this Design!
Ambient Light using NeoPixels and a Arduino Nano as a light source :-)
The lamps shade is printed in PET-G using the “spiral outer contour mode” without any bottom layers.
The base is printed in silver ABS, 0.2mm resolution.
For both prints I used a 0.4mm nozzle.
The Arduino sketch and library I used are can be downloaded at: https://www.thingiverse.com/thing:3297082 or https://www.myminifactory.com/object/3d-print-81732. They are from AdaFruit and I just changed it a bit so the LED's slowly change color. For more info: https://learn.adafruit.com/adafruit-neopixel-uberguide/arduino-library-use
The 6 LED's are soldered in series to form a ring. Because they can take a max of 60mA each, I took the 5V from the Arduino's internal regulator.
Note: I had to hot-glue the Arduino to the base, so it can't move while plugging the USB cable in and out.
If you have any questions, feel free to ask :-)
Do you have constructive comments or think I made a mistake? Please tell me :-)
