I googled around for a while on the feasibility of such a project, but I couldnt find much that was directly related to what I have in mind.
I did find this, but it does not concern dmx.
What I'd like to build is something similar to what is pictured in this video, but instead of preprogrammed visuals to have sound activated/based ones. Here are the tubes I thought of using. (edit)The number of the tubes would most likely be 4/5.
Would this project be plausible using a Arduino based solution? So far i find that it is plausible, but am not quite sure. If yes then what major components would I need besides an Arduino board, the LEDs and the sound detector chip?
