0.06A per LED 196*0.06a 11.5A and does not include anything else you have drawing from the same source. For those reading that assumes all LEDs on set to white. Each LED (RGB) os 0.02A and so unless you have a project that is effectively using this array as a white lamp, then you can probably cut down the power requirements. It would take some testing but if you are only lighting 55% of the LEDs at any one time and you go full power white then you can get away with something closer to 6A

Really nice job! According to the datasheets the ws2812B leds draw a max current of 60mA per light, you have 192 of them which is around 12A max draw! When you tested it and your bench supply dropped to 3V I'm surprised it mangaged to even supply that!
@TheGrrson

That's 60mA if you are running each LED at pure white with full brightness. Each NeoPixel actually has three LEDs within-1 red, 1 green, 1 blue. Depending on the colors you are displaying (by mixing the RGB color) and the brightness, you can keep power draw pretty low with these. A good rule of thumb is just never go full white with full brightness.

Take 20mA per color per led..... Comes to 12 rows by 16 leds times 3 (led colors) times 20 mA = 11520. That is safely to say that 12 Amps is sufficient. Quite a nice calculus indeed, so you prevent from blowing a psu... By the way, I like your approach and build... Very nice indeed...

Is the current going to suffer from running linearly through the whole strip? Would buss bars at the sides supplying 5v and GND individually to each strip maybe help keep resistance down?

Max Current Intake = Max Current Intake by a Single LED * Total = 60mA * (16 * 11) = 0.06 * 176 A = 10.56 A (~ 11A). So recommended power supply is 5V-11A.

hi good video but from my understanding you can not push power backwards on these leds hence the reason for the arrows data power and live power would push forward only. for you to power inject you would do that half way down equaling out the power usage . i have done all of mine on a larger scale my largest is 1,476 led's matrix i power injected 2 times i used a esp32s chip and boosted the data line with a low level converter 3.3v to 5v jump as data pushes at approx 3.3v this helped with glitches as this is on a large scale works seamlessly hope this helps . My power booster is a 60amp power supply it doesn't use that much but i also use that for my led singing Christmas bulbs.

I am kind of new at this but... 16x11 = 176 "pixels". Each of the WS21812 at full-white/bright = 60ma. 176 * 60 = 10,560ma / 1000 = 10.6a. So to drive the entire board you'd probably need a 12a power supply.
