It's become apparent that some sort of DMX tester would be invaluable to members troubleshooting their DMX controlled displays. At the simplest, it could be an LED and resistor affair as shown on Big Clive's page here. For more advanced detective work, something with an LCD and buttons could act as both a DMX test source, channel level display or a start channel setting tool. It all depends on how much people are willing to spend on such a tool. It could be done as a DIY coop to keep the price down and/or be available fully built and tested for those without the DIY skills or time. I've seen some commercial ones, but they were either expensive or almost useless feature wise. Over the past couple of years, DIY ones have been mentioned on other forums, but I'm not aware of any that made it to fruition. Discussion and suggestions welcomed.
