Hello,

I created a remix for this project: https://www.printables.com/de/model/62043-rgb-double-helix-lamp-easyprint

I have add a USB-Micro PCB Socket, because I wanted to save myself the cost of an extra power supply. You can buy the Sockets very cheap everywere. Just look for “micro usb pcb”.

So you can use an old USB charger or connect it directly to a TV or PC via USB.

The max current is 560mA for this lamp, if you run the Code with a brightness of 250. So 5V 1A are more then enough.

I offer here only the Base, Bottom and Code for the lamp. You need to download the rest from the original source project. (click me)

-PIN 2 is push pin. (The other wire has to go to GROUND.)
-PIN 12 is LED Data pin.
-Default LED Type is WS2812.
If you need to do changes, change this in the arduino code.

I also used a 16V 100uF capasitor to reduce interferences and added a 330Ohm resistor between the arduino board and the first LED strip of the data wire.

For print settings, take a look in the 3mf files.

Filament i used:

• Fillamentum PLA Extrafill Wizard’s Voodoo
• Geeetech PLA Glow in the Dark Green

<<< How do you change the effects >>>
There are 4 Lists of effects.
>To switch the Lists: Do a long klick of about 1-2 seconds.
>To switch the effects in a List: Do a short click.
>To activate sleep mode: Do a long click of about 3 seconds.

1st. List (palettecrossfade): 1 effect
2nd. List (palette mode): 12 effects
3rd. List (effect mode): 11 effects
4th. List (solid color mode): 18 effects
