Thanks, that is good insight. I will build a prototype with 1 or 2 inverters, I don't expect very long distances on the output trace, but I will only know for sure when I am at the museum.

I know, but I need to feed 21 strips in groups of 7, so three data pins each with seven outputs. I thought about 3 74hct14 to get 5 each, then one more hex inverter to make 2 additional outs for each of the three lines. That last „shared“...

thanks, I found 3 74hct14n in my drawer. for 3x7 outputs I need a fourth though, since I can only drive 5 strips per IC. for the additional outputs a 74ac14 should also be ok, since I already pushed the signal with a 74hct14n inverter, right? (I...

thanks, I may even have them laying around somewhere.

here is the link for the amazon thingy...

hi there, I have yet another ws2812 project that involves 21 led strips each 1.5 to 2m long. they will consist of 3 groups of 7 strips. each of the strips in a group will receive the same color and pattern info, so I can use the same pin to...
