Fantastic explanation dude! I was just talking to a professional LED engineer the other week and he mentioned this technique about how to smooth out data signals over a great distance. Please keep these incredible videos coming, You have a true gift for making hard things simple.
Great to see someone actually using the correct level-shifter/buffer for that purpose 👍 The HCT125 is available in a small single gate (1G) version, the 74AHCT1G125GW, which makes for a perfect small in-line converter board. Also, if you can't get a 125, basically any AND/OR/XOR gate will do. So any 74xT1G[125,34,32,17] should work.
Another great practical video, thanks. I used RS485 in kinda the reverse scenario of this on a project recently, and ended up with an arduino mega, with a dmx host shield very close to the very long strip end ( think I ended up around 15m of led) and signaled what it should do by sending dmx from a lighting desk. The mega listened for the dmx value and colour shifted accordingly
Thank you, i was going in the wrong direction. So i wasn't using an esp32, but i will now and i was not using a capacitor, never came up. That was a very informative video and now I'll get on the right track i felt like i was in class, Cheetos on my keyboard and the only sound was my labradoodle snoring, was like 1994 in Engineering school minus dog. Ok i'm just starting over after i find the capacitor box.
Many people seem to think that Cat5 etc. twisted pair is good for standard "SPI" signals because that's what's used for data cabling but while it should be used for differential systems like Ethernet and RS485 (Cat5 is RS485 compliant) for standard single ended data it can make things worse due to the higher capacitance of the cable.
Thanks for including that bit about the backup line.

Ah, thankyou so much for that kind comment, and I'm glad you find them helpful!

Thanks for sharing and explaining so well !
