Hi racemaniac,Do you mind if I move this discussion over to the LED string saber thread? Now there is LSOS support for neopixel (not yet released, but I included a video, quite recent), I think it will give a new boost to the dicussion about this!
My power supply is 4 nimh batteries cells (4000 mA each). Theese are special Radio Ccontroled car batteries (should deliver up to 20A)At the begining I'm at 4.9V and at the end I was at 2.8V
Ok so back with a new test, I've powered up both line, so I run a test for 8 minutes, no batteries problem, I run two 144 led with no voltage drop problemso I run 288 led at full green end full blue.it draws 4AI've checked the voltage and I have a strange voltage drop that I don't understand, why near my batteriy I have 4.1V and why on the strip both end I have 2.7?If I plug the arduino power on the breadboard near the strip it reset when voltage on strip is nears 3.3 (wich is the minimum for a Atmega328P@20MhzI thought connection in // does not suffer from voltage problem? But that said it works correctly, but with a good voltage my strip would be even lighter see the schema (it is one led in it, but it is to compact the view, the 2 strips are with 144 led)thx
Hi di you have a problem with the voltage drop in the led strip?I'm doing the same thing with 144led/M strip and with powering only one side it drops at least 2V, I'll test powering both sides
my first 144leds/m strips arrived . i'm wondering, do you guys also have strips that are composed of 2 strips of half a meter? (so in the middle you've got 2 leds that are a bit further apart).

Ok I've droped the breadboard and soldered strip directly on battery for test, it's working here is an example with only one strip, it is already a strong green, I will do a test with two strips:Lightsaber TestI've added a little effect, there is a kind of light ring traveling on the tube, it is not a malfunction
In the tube it is some baking paper:
Sorry i was not able to édit my answerIRL it is leSS brightBut it is quite bright with one stripYou cannot see the led if it does not touch the paper.I have to build a centering ring to put every 20 centimeter in the tube
