Yep! Exactly. I did something similar a few months ago. I took a big thick speaker cable (10 gauge) and wired it to my power supply. I made a bunch of janky splits in it and soldered some more wire so I could inject power into the strips. Wish I knew about these things before I did all that work, this is what I would use now (not this exact one but one like it):

EVERSECU 2Pack 1 to 4 Way Port DC Power Split Splitter Cable Pigtail for CCTV Cameras DVR NVR LED Light Strip DC5.52.1mm (DC Power Splitter Cable 1 Female to 4 Male) https://www.amazon.com/dp/B07JKSDNCF/ref=cm_sw_r_cp_api_i_TG20Db0SACK3T

Keep in mind those connectors handle a max of 5 amps and if you buy a shitty one probably less than that. So those will only help so much, you still gotta do some wire splitting.

For anything more use Anderson power pole (its not super cheap but really your best bet if you want a connector that can handle the entire 18 amps).

However I only inject power into the beginning of the strips, you can do the end too (I’m assuming) but it’s twice as much work. I’d see if you can just attach each strip to power. You’ll want to connect the data and ground lines between each strip obviously (if you are wiring the strips together so your controller sees them as a single strip).

If you inject power into each strip they will all be nice and even and your project should look great.

I'm not experienced with batteries. Hopefully someone else can help you with those.

This power supply might be more user friendly. Just get a barrel jack and you can easily connect it to the leds. I used this type of psu to power up my xmas lights last year on my balcony so as long as it doesn't get wet it should be fine outside too.

WS2018B
Is what I purchased originally. I may get different some that are just white/warm white since their for interiors of buildings and I'll have no need for RGB.

Down the road for sure I'd love to do a disco rave party in a big warehouse, random flickering fluorescent lamps and white/blue welding flashes. Endless possibilities for sure :)

For some reason I couldn't see the second half of your first comment, don't quite know what happened there... But I'm working with WS2811 strip. Just in case, here's what I got:

https://www.amazon.com/dp/B0775CC559/ref=sspa_dk_detail_4?psc=1&pd_rd_i=B0775CC559&pd_rd_w=LUwIe&pf_rd_p=8a8f3917-7900-4ce8-ad90-adf0d53c0985&pd_rd_wg=sjVz3&pf_rd_r=E49FJSYMSCZR16D0TF4R&pd_rd_r=195ec17e-9f6e-11e9-9c8d-95537dbb79e8

Now I actually have seen that code, realistically that's what I meant by the three pin method. I guess the better way to say that I have seen people do static colors with non-addressable LEDs, my lights are all individually addressable. Sorry, I feel like I'm telling you information you already know lol.

Now that code wouldn't work for my lights, correct?

I saw. Excellent job!

AliExpress. I don’t have a link to them.

These are similar from Amazon:

u/kelvinmead ¡ 2 pointsr/FastLED

yep, no problem

fastled can be as simple as, set colour, set led, and then it would just take some basic coding to have times on and off.

if your working on a micro scale, then use milliseconds and "flash without delay" as a start, but it sounds more like using am rtc would make things a lot easier

ESP-8266 people! I went down the fork rabbit hole on github and found this one, EmteZogaf/FastLED/tree/dma. It:

  1. Adds RGBW support for RGBW SK6812 strips like these. Neat! (I didn't know they existed)
  2. Adds ESP8266 DMA support*. Only on pin 3, however. No parallel support.*

The real question is are your strips 30 LEDS per meter, or 60? If it's 30 per meter, you can seriously downsize your power supply.

For reference, I have an array of strips of 60/m ws28xx, and bought this 300W 5V 60A power supply. I have 987 total LEDS, that at max intensity would consume 295 W and 59 A.

The strips of 60/m are approximately 18w per meter.

If you are using the same strips as me, then the maximum supply you would need would be 150W 5V 30A

One other important note... the power supply is not a constant current supply. The current drawn from the supply will vary depending on the intensity and refresh rate of the data.

Basically, the "max" draw should only happen if you are setting each individual to it's max intensity of white, and signaling a refresh of every LED in the array at 800kHz.

Here's the math. You'll see I added some margin to the final values for safety. You may not have the same LED's as me, but the math can be done the same way for whatever your LED chipset is.

50 LED's per segment / 60 LED's per meter = .8333 meters
.8333 meters 8 segments = 6.667 total meters
18W per meter
6.667 meters = 120 Watts per matrix
120 Watts / 5V = 24 Amps @ maximum intensity

Edit, I just noticed your link to your LED's, and they consume 0.3W per LED. Just so happens that equals 120 Watts, so the recommendation above should hold.

I am newbie too! I use very newbie friendly methods. No solder!

https://www.amazon.com/gp/product/B078RT3ZPS/ref=ppx_yo_dt_b_asin_title_o05_s00?ie=UTF8&psc=1

I just use one of those every 150 leds. If I am using the 300 led strip, the 60/m for 5m, I use 8amps instead of 5. The connector that comes with the power supply works directly with the led strips from the same company.

u/pikipupiba ¡ 1 pointr/FastLED

I linked the one I'm using. I also just ordered some of these and these. Will those both work?

Also, are there any smaller options without the pins sticking out? I just want a small little one channel converter...

These sort of 12V versions are in Amazon, such as this:

Just a no name brand off amazon. Although i believe i have another one coming from adafruit as well

I've used this before, the length may be overkill!

Yea, I have had those a lot too. In portable projects where they are likely to get jerked around, I will use plastic cable puller (https://www.amazon.com/Uxcell-a16011800ux1611-Plastic-Pulling-Leading/dp/B01FM7V6P8 - you can get them at hardware stores) and use electrical or regular tape to fix the strip to the plastic cable. It prevents the strip from bending too far.

u/ZacharyRD ¡ 2 pointsr/FastLED

For posterity, found a battery solution that worked great, iof anyone else has the same problem -- https://www.amazon.com/gp/product/B01M7Z9Z1N -- has a built in switch, has 12v out via a barrel jack, has 5v via USB. USB stays on as long as the switch is on, even under tiny load (just an Arduino). I linked it to a barrel jack adapter, here: https://www.adafruit.com/product/368 . Power to Arduino via USB, common ground to the barrel jack power adapter terminal block, capacitor across the terminal block, power and ground out to the Neopixel strand.

" From the CAT5's the solids are data and the whites are ground. "

This is wrong. Using a twisted pair for data/ground adds a lot of capacitance to the data line, so I would expect problems.

I use this wire on my current project, driving 300 LEDs with a Wemos D1 Mini (8266-based, 3.3V). My Wemos is 15 ft from the LEDs. The secret is to use a sacrificial LED to act as a level shifter/data repeater at the start of the cable.
