Collaborative way to achieve a low cost graphical waterfall


I want to build a graphical waterfall like this one .

I saw a similar post here but with incomplete information ... ( )

I want to know if someone is interested in building one with me! We'll exchange ideas, code and all that.

I know how to do the software, I'm a software engineer. I need help with the hardware part.

I have already compiled some papers of 2 guys who have build one. I can share them with you.

How big can we make it ? 256 valves ?

Thanks ahead!


Hi I am interested with the subject. I am a mechanical engineer.
