I want to build a graphical waterfall like this one https://www.youtube.com/watch?v=Z2LUz2WVcek .
I saw a similar post here but with incomplete information ... ( http://forum.arduino.cc/index.php?topic=60117.0 )
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 ?
