Thanks for all that close up detail! I've had the level shifters in a bag for an age, tried to power some sk9822/apa102 without the shifter, loads of problems. Thought I'd give it a go.. Followed the basics on the level shifter - which on other videos was terrible about the wiring, and from yours, I have a fully working 78 strip on top of my Bambu Lab 3d printer. Thanks! from UK :) Liked and Subbed!!
For soldering, it helps a lot to add a little flux paste so it melts over where you soldier (this also protects the board/items nearby w/ a layer of liquid) You want to heat the metal tho, so the soldier attracts to the heated metal. So you heat the pin and pad of the component, then you apply the soldier to the hot pin n it will melt around the pin perfectly. Hopefully this is helpful (I see it's been a yr since uploaded)
Okay, so this is pretty basic and exactly what is needed. This verified what I thought. No idea how or why these things work but I don't think that is necessary. Thanks!
Thanks for sharing! I had heard that for the WS2811 strips a logic level shifter was needed but decided to try my 55ft string without it and sure enough when displaying white there was a noticeable flicker. Fortunately I had ordered a set of these and when I installed it on the 3.3v output of my ESP32 the flicker went away. I've heard these are less than ideal for upconverting the signal, however, it seems like there aren't a lot of other solutions that will work with a digital signal.
I like the fact that we are about at the same level of understanding and soldering skills ! :-D Now, I wonder, will you use this PS for your Christmas Tree ? Seems a bit bulky to me.
Quick question. You are powering both MCU and ledstrip from the same PSU. I have this flickering problem too but i use separate PSUs to the MCU and led strip.(tried using the same but blew my first RPI zero 2w..) How would i go about wiring it up like you did but with separate PSUs?
You can use the breadboard to keep the pins and logic board stable for soldering.
Thanks for sharing your knowledge. This was really helpful.
I appreciate the close-ups. All tutorial videos should be this detailed. Thank you!
I logically am not on the same level as you. Which is why when I made the shift to surround sound in the living room, I had you do it!
Very helpful video, thanks for going over which wires are for which device and how they interact with each other

I put the pins into a bread board 1st, then solder, keeps everything lined up

Great video, what effect would you recommend if we want to cycle through all solid colors in a seamless manner (ie fade from color to color)
Same for ESP32 and WS2812b ? Can u do same as this too?
yes
@@epiicSpooky thanks
I know this video is a bit older but what would a more permanent application/set up look like ?
now i know..
thanx..
Wrong logic level shifter. Use a 74HCT125 instead
