Earlier today, there was some discussion about using WS2811 chips as a basis for a pixel strobe. The general consensus has been that DMX (either conventional or as E1.31) is too limiting to achieve a strobe effect by itself due to the data refresh rate. So, we're back to thinking about a pixel strobe controller again. Such a controller would drive the pixel strobes and take it's input from a DMX stream. It could have various parameters such as: Brightness - you might not always want to flash at 100% intensity Rate - how often the strobes flash Duration - how long each flash lasts for Fill - how many strobes flash at once You could set these parameters before the strobe event (while they are dark) via a few DMX channels, then use another channel to turn them on/off. Perhaps the brightness channel can serve as that function. I'd envisage a board with DC input, DMX input and pixel output connectors. It would also have a DMX address DIP switch. Pixel type (6803 / 2801 / 2811) could be selectable via jumpers. Anyway, that's my guess on a starting point.
