Related, I would love to see a video covering where to get a proper enclosure for the power supplies such as the meanwells
Your breakdowns and spreadsheet analysis are crazy good and extremely helpful. Thank you for putting this all together! You get a like and subscribe, thank you very much!
Great video. Loving the technical detail
Incredibly informative and easily digested. I'm really glad I found your channel. Keep up the great content!! Thank you
Thank you, great to hear that! :D
All the explanations is clear, thanks ❤
I thoroughly enjoy every bit of viewing your videos. Excellent breakdown and summary of technical details into “human readable” format.
after I spent too long poring over a bunch of the top results about this topic on Google (which are all word salads meant to boost SEO it seems) you provided a very clear explanation of the information I was missing. appreciate it!
Glad to hear it!
Thx for tips. Very clear and to the point.
Thank you. Great explanation and cleared up a few things in particular 'regulated' pixels. Thank you!
You're very welcome!
Enquiring minds want to know about the mysterious new 24v high CRI addressable RGBW COB (so many acronyms!) strips!
Yes I keep postponing that video because I'm trying to cram too much inside of it. This video was a result of taking some of that out so I'm getting closer but because of some travel plans it'll still be a few weeks before I can finish it. Come to the Discord if you want to discuss it, it's released (the 24v COB RGBW) and it's good for whites but there are some tradeoffs for everything else. It's also already in the power sheet!
@@IntermitTechwhere on your discord can I find it? Sorry for being a dummy, I have tried to scroll through different channels with no success 🥲 thanks!
... Or maybe, the strip exist and not the discussion about it on Discord 😅
Higher Voltage is always MOAR better ;), lol. Thank you for your content, best LED Addressable content out there. Also, really enjoy your boards!
Thank you very kindly! :)
Excellent post! I was looking for an aluminum channel that has a raceway attached with it as to run data and some power injects. Have you found anything that can hide both the LEDs and the cables?
Do you plan on doing a video on silicone diffusers?
Good Video. Do you find the cob strips as 'bright' as regular LEDS, diffused or not. 5v mainly
And now please give me that explanation ~20 years ago when i was in school x_X"
Awesome video as always! I Don't see the link to the 12v with buck converter built in strips. curious as to what they cost :)
Apologies I just completely forgot to add them, just did!
was wondering if its possible when getting a digtogo to replace the ESP32 with a QUINLED-ESP32-AE+ ? :3
Ah no it is not. The dig2go is fully enclosed product. The pluggable ESP32 boards only go on the Dig-Uno and Dig-Quad
Can you do a video on kitchen under cabinet lighting that has a good white but is also addressable rgb for specific occasions?
I will have one in the future but it's a bit delayed. There is basically only a single strip that is suitable for that and that's a recently introduced addressable 24v COB LED strip in RGBW. It's a bit worse in the color department vs the RGB 720LEDs/m version but it does finally have decent whites and I think would do fine in such situations. My video should come out in a few weeks about it.
can you link the strip, maybe I can get them via 11.11 sale still.@@IntermitTech
Thank you for the informative video. I want to install a ceiling (~30-50ft) of leds, and I also want some more accurate warm white along with RBG. Would you recommend me to go with the WS6812 RBGWW - 5V, or wait until FCOB - RGBW 24V version comes in the near future?
If you want decent white the FCOV 24v RGBW version is the only option, everything else is low CRI. It's already available on Aliexpress from BTF lighting.
@@IntermitTech the thing is that the fcob rgbw you mentioned is not addressable right? So, if I want good quality white, I will just have to sacrifice addressability?
No it is, but it has 7cm wide zones but good white
@@IntermitTech is the ws2814 the one you’re referring to? This seems to have a larger addressable zone (56 leds), but its still addressable. Would you recommend this over Ws2811 rgb + ws2811 cct (if I can run 2 strips parallel, though this maybe too much work)?
@jadenphan8106 if you want good whites on addressable strip, the ws2814F cob is only option really. Running 2 strips can also be an option yes. The ws2811 only white strips can also work al and are CRI90. I'll have a video in a few weeks.
Thanks for the good info.
I want to run at least 3 WS2815 60 LEDs/m strip with 12V 30A power supply in parallel. How can I do the connection. Would 30A damage the WS2815 ? Pls suggest.
As long as the power supply is the right voltage you just need enough Amps, more is fine. Amps are drawn, not pushed like voltage is.
@@IntermitTech Thanks. I got my answer.
Isn't the WS2815 strip individually addressable on 12 volt?
Correct, they are one of the exceptions I also show later in the video! :)
The next step for manufacturers will be to make led chips with multiple lower power series LEDs in the one chip.
9 LEDs for 12v (3 red, 3 green, 3 blue).
18 LEDs for 24v (6 red, 6 green, 6 blue).
Yes, those already exist in COB LEDs and I have some in already that are in addressable form but the problem will become the forward voltage difference between the colors, the way you describe it won't work or you are going to be burning a lot of power for some color inside of resistors and such. Still, it can be done and at some point we'll see a COB LED, LED strip I also imagine.
@@IntermitTech the amount of LEDs of each colour does not have to be the same. Unfortunately there would be more red LEDs than blue (opposite to ideal) but this could be compensated for with an internal calibration profile to ensure even intensity. This would make for a chip with maximum efficiency and very low voltage drop.
Are any chips available like this anywhere at the moment?
@dougschafer5161 yes there are in COB LEDs, but none that I know of on a strip yet.
@@IntermitTech thanks for the info.
Would be very interested if you come across any in the future. Thanks for your great content 😊
What's the best way to run 12/24v addressable strips inside tracking with full beam diffusion on a house roof line?
Curious as well
Full diffusion mostly has to do with the distance of the LED to the diffuser. With 60LEDs/m generally you'll need about 1.5cm to 2cm distance between the LED and the diffuser itself, we did some tests with that on a livestream a while back.
Of course going for the COB variant can help a lot with that since they are diffused by themselves, then even just 0.5cm is plenty and it'll look very nice if you want the "smooth stripe" look!
The problem with COB's is they don't come in IP65 and the 60's require power injection both sides of the 5m strip so that becomes a nightmare to hide on long exterior runs. Are there any 10M roll addressable strips available (possibly 48v) out there as that would solve half my problem? @@IntermitTech
So if i want to do a ~150 meter run around my house with WS2811 60leds/m 12v i'd need what, like 33 points of injection? -- just going off specification that stated 5m per string.
Yup, 150 meter is an insane amount. Or rather, I haven't checked that number hit that's really really long!
But if one diode in row dies the voltage rises end destroys the rest or i missed something?
Yes, it's possible that if a single diode fails the voltage will rise but that shouldn't immediately destroy everything, often it has a bit of a tolerance. This is at least not a common occurance, that a strip goes bad because of that reason.
Well, they could just fit three or so led dies of each color in series into one 5050 package instead of wasting the power in only heat emmitting blind diodes 🤔
even een vraag tussendoor...ben jij toevallig nederlands
Jazeker, viel het op?
