WS2812 strip with both 5v and 12v supply on the same strip!

Good find! I actually may be buying a set of these for a work project.

Wow, though, that is just asking for a miswiring… be careful where you put the 12V folks :slight_smile:

Wow, this could just save me a TON of work… I ordered one and will let you know how they turn out…

Just what the doctor ordered!
Or will order.
Even though he’s not a doctor…

Looking closely at the specs it states that when using 12v you can only slice the strips every 50cm (30 leds).
Also there is a regulator mounted on the reverse of the strip. They don’t picture it on the 60 leds/m one but there is a pic on the 30 leds/m http://www.aliexpress.com/item/5m-DC12V-WS2812B-addressable-pixel-strip-waterproof-in-silicon-tube-30pcs-WS2812B-M-with-30pixels-36W/32350328728.html

With shipping, that’s about $14 a meter. I can get the usual 5-volt strips for about $6 a meter and throw in a 3A buck converter for $1 for every meter for a total of $7 a meter – with the ability to use 5-volt, 12-volt, or anything up to 35-volt power supply. I’m not sure I see the benefit.

60 leds per meter * 60 ma per light * 4 meters = 14.4 Amps unless I’m doing my math wrong.

just hooking up a 12v to the end is a lot less wiring and soldering etc if you’re doing long strips

If I’m saving $7 a meter, I don’t mind four extra soldering points! :slight_smile: Everyone will have their own preferences though… one meter with two voltage options OR two meters with one voltage option (or unlimited voltage options with the buck converter and some soldering). At this point in my projects, I want more blink (LEDs) than bling (dual voltage) for my money.

:flushed:

You have got to be f*cking with me…

Who has strips for $6/meter?

25 meters for $140.60 = $5.63 a meter.

The above ARE only 30 LEDs per meter though.

A quick look found the below for $8/meter for 60 LEDs a meter.

But the above are “buy now” prices. I’ve found them for quite a bit less with bidding. You lose a lot of the auctions, but the ones you win are worth it. Not a good option if you have a deadline though.

Reliable seller, yes?

@allanGEE They might be less expensive, but they’re not high density.
Those look like the 30 LED/m ones, not the 60 ones I think we’re all used to.

@Danny_Evans once yout receive it I’m very curious how they are made. The little SMD components are Caps not resistiors - that’s why I’m wondering …

@Ira_T 5m = 150 led as said in the offer

I found the price expensive

@Jeff_Mizener As reliable as ANY eBay seller when you’re trying to pay the lowest price possible. :wink:
I ordered 10 reels of 5 meters each (will be trying to light the outside of my house this summer – in time for Christmas 2016). 9 out of 10 worked perfectly. The 10th one only lit up to the 12th LED on the strip. I’m sure it’s just a bad connection somewhere, but I haven’t had time to pursue it. I contacted the buyer and he/she is sending a bunch of clips and connectors to try and help me solve the problem – so I appreciate their effort. Considering I’ll have to chop and join some of the strips anyway, it won’t be a big deal for me to fix a connection or even discard a bad LED.

now this is a nice find, i tend to buy WS2812B 60/m for $9/10, but this $8 is the lowest i’ve ever seen. I’ve sniped auctions at $8.5, but this is incredible. Nice find.
