Thanks for the suggestion! For the next version of this project, I'll definitely be using an SMD ESP32 package rather than these D1 boards, and also incorporate a logic level shifter. Component prices from PCB manufacturers like JLCPCB are much cheaper than buying development boards from Amazon like how I currently am.
I know folks have mentioned a logic level shifter, you could just pop one pixel on the board itself, then tell WLED to skip it, as soon as the data signal hits that pixel it will automatically ramp up the voltage. It would probably be easier to do that than incorporate a logic level shifter @@PearsonDesign-qn7sx
@@PearsonDesign-qn7sx Hello, Loved the work. Great design. However I agree with this commenters advice about level shifting the 3.3V TTL from the ESP8266 to the nominal 5V TTL of the lights. In my experience I mostly notice problems with ESP32's not having the level shifter. Will cause random glitches. The ESP8266 seems to be more tolerant of this. And I would recommend the ESP32 for its faster processor. You can run into issues with random restarts with the ESP8266 when you push it too hard. In my person experience anyways. Great job on the vid!
Thank you! Yes, that would be pretty straightforward to do. This isn't something I've looked into though as I usually keep the controller right next to the LEDs themselves, typically on the underside of a table, where I also mount the controller itself. That would certainly be useful for longer runs with centralized controllers though!
You can just use a 5V tolerant pin on the ESP8266. I've run WLED like this for more than a year and nothing went wrong. Please correct me if I'm wrong.
Hey, thanks for the info! From my usage with the strips I use, I haven't ever ran into this issue. I hooked up an oscilloscope to the data pads before and after the first LED, so that I could measure voltage at the peak of the data square wave. As expected, the the wire going in measured at 3.3v, however the output signal was at 4.8v. Admittedly I don't have much experience with this, however this test shows that the first LED effectively operates as a logic level shifter (provided the input voltage meets the trigger threshold). I'll do some more tests on this as I'm quite intrigued.
Thanks for the tip! I opted to keep it full length to make soldering easier, as the holes in the board aren't properly shaped for these connectors, and there was a lot of space to fill. In the future, I'll probably seek out a better fitting connector.
i tried installing wled in node mcu 8266, found the port initiallized ok, even install goes to 80% & then finalizing error tried several times no success, also wled does not say anything about reset & flash buttons i tried them also still no sucess.
you might wanne add a level shifter for the data channel, also an esp32 is adviced if want over the air updates for wled

The ESP8266 supports OTA (Over-The-Air) updates, so you can push a new firmware OTA. Or am I missing something?
@@PeetHobby you can push the new wled version over the air, new boot loader etc is by my knowledge always wired

Nicely made, simple and functional! Like the clip-on/clip-in holder!
from my experience with wled, adding a relay to fully switch off the strip during standby (led off) is a must have. but great video and nice job
Thank you! And interesting, this isn't something I've encountered with the strips I use. What brand of LEDs are you using?

Nice video, great detail and at the same time entertaining! Looking forward to see more...
A small suggestion... why not make a DIN rail adaptor for mounting it into a electrical cabinet?

Nicely explained, and it's also a fun little project. 👍
I hope you will upload more videos in the future. Good luck!
Nice job for your first video
Thank you!
Nice start! Keep it going!
Great video! Thank you for sharing.
Nice simple video, good explanation. What rating are the fuses? How many Amps?
Is it possible to connect 144led/m with 60led/m in wled? They’re both 5V and have the same 3 copper connections.
Pixel density shouldn't have any impact. Note that this controller only has one output pin, so you'd need to connect both strips together.
The level shifter is missing.
74HCT125 or 74HCT1G125GW (74AHCT125 or 74AHCT1G125GW)

Nice project! 🍒
Instead of bending, you should have trimmed what sticks out. BTW nice work

Very cool.
Hello, is it possible to assemble components without using a PCB?
sweet

Hey bro nice vídeo How i can contacto you? For talk
