DMX snowfall tubes


Recommended Posts

Hello dear light-creators.


I have been working on DMX controlled snowfalltubes.


And have  4 working examples now. I used arduino Atmega328 chips to get to the point. 


I wanted triggerable, RGB DMX tubes of 1 meter long, 30 pixels in a row. I use WS2801 pixelstrip for that, back to back in a 1 meter acryllic transparant.


Designed a very simple pcb for that, with Eagle and had 5 pcbs made. I am not a very good programmer, so I used 1 arduino for the DMX input and for each tube per pcb an other, in total 3 atmega328 chips, which are low cost chips.


Each tube takes 4 dmx adresses, which are easy to program.  the channels per tube are 1 RGB and 1 enable channel for easy trigger. One PCB take thus 8 DMX channels in total, driving 2 tubes.


The first firmware is very simple, but I came to the idea to enhance the firmware, to also have the possibility to let water drops fall down and fill the tube for instance.

More in the future as programming continues
